LAS VEGAS — Daimler Trucks North America (DTNA) Monday introduced the first SAE Level 2 automated truck in series production in North America with the latest enhancements to the Freightliner new Cascadia.

Level 2 automation means the truck is capable of both lateral (steering) and longitudinal (acceleration/deceleration) control.

The truck is part of the revolutionary truck technologies featured by DTNA at the Las Vegas Motor Speedway during the 2019 Consumer Electronics Show (CES).

According to the Newsal Highway Traffic Safety Administration, 94 percent of crashes are attributable to human error.

Automating acceleration, deceleration and steering reduces the chance for human error, mitigates collisions and can potentially save lives. These technologies can also enhance the driver experience by making the truck-driving task easier, thereby improving driver comfort and well-being, according to Kelly Gedert, director of product marketing for Freightliner and Detroit.

DTNA’s expertise in automation is backed by Daimler Trucks, which also said Monday at CES an investment of over half a billion dollars and an addition of more than 200 new jobs in its global push to put highly automated trucks (SAE Level 4) on the road within a decade. Most of these jobs will be located at the new Daimler Trucks Automated Truck Research & Development Center at DTNA’s headquarters in Portland, Oregon.

In May 2015, DTNA pioneered automated driving with the introduction of the Freightliner Inspiration Truck, which was the first automated truck licensed to operate on U.S. public highways.

Today, the new Cascadia delivers SAE Level 2 driving capabilities with the Detroit Assurance 5.0 suite of camera- and radar-based safety systems. This new, proprietary system marks a key milestone in Freightliner’s relentless pursuit of industry-leading overall safety, driver experience, and fuel efficiency, Gedert said.

The system can accelerate, decelerate, and steer independently. The Detroit Assurance 5.0 Adaptive Cruise Control and Active Lane Assist features make automated driving possible in all speed ranges for the first time in a series production truck, including:

  • Adaptive Cruise Control to 0 mph: Improves safety, efficiency and driver comfort by automatically decelerating and accelerating to maintain a safe following distance. This technology is especially important for maintaining a comfortable driving experience in congested traffic conditions where repeated braking, accelerating and resetting of traditional cruise control can lead to driver fatigue.
  • Active Lane Assist: Consists of Lane Keep Assist and Lane Departure Protection. When Adaptive Cruise Control is enabled, Lane Keep Assist supports the driver by using micro-steering movements to keep the new Cascadia centered in its detected lane. With Lane Departure Protection, if the truck begins to drift without the turn signal engaged, the system will counter steer the truck back into its lane and give an auditory and visual warning.

In addition to Level 2 automated driving features, the Detroit Assurance 5.0 active safety and advanced driver assistance systems are designed to keep truck drivers, pedestrians, cyclists, and other motorists safe:

  • Active Brake Assist 5.0: The fusion of Detroit Assurance 5.0 camera and radar technology detects moving pedestrians and cyclists in front of the truck and can deploy full braking – an industry first. It can also detect and mitigate a collision with full braking on moving and stationary vehicles and objects.
  • Side Guard Assist: Detects objects, including pedestrians and cyclists, in the passenger-side blind spot for the tractor and a full-length 53-foot trailer, another industry first, and delivers an audible and visual warning.

“The enhancements we’ve made to Detroit Assurance have the potential to make an immediate, measurable and positive impact on overall North American road safety,” Gedert said. “In fact, fleets with trucks equipped with forward collision mitigation systems can experience a 60 percent to 80 percent reduction in rear-end crashes, resulting in potentially fewer accidents and reduced operational costs to our customers.”

Detroit Connect Analytics provides fleets with analysis and key insights on the performance of the new Detroit Assurance 5.0 safety features. Fleets will be notified if drivers have their hands off the wheel for longer than 60 seconds.

Gedert said the new Cascadia also features one of the industry’s most efficient designs, inside and out.

“Thanks to DTNA’s significant investment in ongoing R&D in aerodynamics, powertrain development and systems intelligence, the new Cascadia delivers a 35 percent improvement in fuel efficiency compared to the first Cascadia introduced in 2007. This equates to annual savings of up to 4,700 gallons of fuel per truck, which is the amount of fuel consumed by six typical family cars in a year,” he said.

The new truck also offers aerodynamic enhancements the include Aerodynamic Height Control. An industry first, Aerodynamic Height Control electronically lowers the suspension height at 55 mph to optimize airflow over and under the front of the truck and reduce drag. Other enhancements include Michelin X Line D+ Energy tires developed in collaboration with Michelin, which reduce rolling resistance in 6×4 applications, and a low ground clearance bumper.

Gedert said another critical component of the new Cascadia’s performance is its Integrated Detroit Powertrain, a powerful combination of a proprietary heavy-duty engine, transmission, and axle that is designed to seamlessly work together for maximum efficiency. The integrated powertrain features Intelligent Powertrain Management 6, which uses the truck’s kinetic energy to automatically adjust to the truck’s surroundings by reducing braking power and making transmission and engine adjustments, saving fuel and reducing wear and tear on components.

“It’s not just the new Cascadia’s aerodynamic shape, specific options or powertrain components that make it the best – it’s that these features are engineered to seamlessly work together,” said Kary Schaefer, general manager, marketing and strategy for Daimler Trucks North America. “And we are the only truck manufacturer to offer that level of integration.”

For fleets concerned with fuel economy, Detroit Connect Analytics will also introduce new Intelligent Powertrain Management reporting capabilities, and the fuel analysis will indicate if the vehicle is using Aerodynamic Height Control, Schaefer said.

“With more than 65,000 customer deliveries to date and 50,000 on order, the new Cascadia has proven to be the Class 8 truck of choice in the industry,” she said. “We’re proud to be once again raising the bar.”

GALESBURG, Mich.— Power management company Eaton says it is contributing several components to truck manufacturers participating in the Department of Energy’s (DOE) SuperTruck II program.

SuperTruck II is a partnership between the DOE, truck manufacturers and equipment suppliers seeking to improve freight efficiency more than 100 percent over an equivalent 2009 model, and improve engine brake thermal efficiency performance by 55 percent.

The $100 million program is funded by the Vehicle Technologies Office of the U.S. DOE and industry partners.

Eaton is supplying a number of leading-edge technologies that improve fuel economy and reduce emissions to Original Equipment Manufacturer (OEM) teams. These include a high-efficiency transmission that achieves additional fuel savings by enabling engine-off coasting and waste heat recovery; a 48-volt mild hybrid electrically regenerative accessory drive that charges the vehicle’s batteries, efficiently runs the air conditioner and other accessories, and replaces the alternator in linehaul commercial vehicles; and precise exhaust gas recirculation controllers that enable simultaneous fuel and emissions reductions.

“This is a great opportunity for Eaton technologies to contribute to a program focused on improving the efficiency of commercial vehicles,” said Dr. Mihai Dorobantu, director, Technology Planning and Government Affairs, Eaton’s Vehicle Group. “We’re excited to work with several OEMs involved in SuperTruck II as we strive for a common goal of cleaner, more fuel-efficient commercial vehicles.”

SuperTruck II is a continuation of the DOE’s SuperTruck initiative, which launched in 2010 with the goal to improve heavy-duty truck freight efficiency by 50 percent. The long-term objective of the project is to develop technology that can lead to cleaner, more efficient heavy-duty trucks, which haul 80 percent of goods in the United States and use about 28 billion gallons of fuel per year, accounting for around 22 percent of total transportation energy usage.

In addition to the components Eaton is supplying to the SuperTruck teams, it offers several other technologies that help truck manufacturers achieve stringent upcoming fuel economy and emissions regulations.

“Since 2008, Eaton’s Vehicle Group has been laser-focused on reducing emissions and fuel consumption,” Dorobantu said. “We have—and continue to develop—technologies that reduce NOx emissions and improve the overall fuel economy of internal combustion diesel engines, as well technologies for electric, hybrid and fuel cell commercial vehicles.”

Several products take advantage of Eaton’s modular variable valve actuation technology, which allows OEMs to choose the technologies they want to use based on their needs.

Examples of what Eaton’s Vehicle Group offers include diesel cylinder deactivation (CDA) and variable valve actuation (VVA) technologies. Both technologies can be used to reduce fuel consumption between five and 25 percent, increase the rate of aftertreatment warmup and maintain higher temperatures during load operation. CDA and VVA technologies can also be used at road loads to achieve active diesel particulate (DPF) regenerations without requiring the traditional method of dosing the diesel oxidation catalyst.

Eaton’s CDA technology can operate at up to three to four bar BMEP at all speeds, which reduces emissions by improving aftertreatment thermal management while providing better fuel economy. Similarly, intake valve modulation can be used at higher loads to enable Miller cycle operation to improve engine fuel efficiency.

Another technology to help on the path to regulation compliance is Eaton’s TVS EGR pump, which is designed to save fuel while meeting new global emission regulations.

Eaton’s positive-displacement TVS EGR pump enables the use of a high-efficiency turbomachinery to lower engine pumping losses and increase fuel economy. The TVS EGR pump is driven by a 48-volt electric motor, making its operation completely independent from engine speed and significantly more controllable than competitive pumpless EGR systems.

Additionally, Eaton’s new engine decompression brake can help OEMs with regulatory compliance. Fuel economy and emissions regulations are driving engine downsizing and down speeding in commercial vehicles, which is resulting in the need for higher braking efficiency to maintain braking effectiveness at lower speeds.

Other variable valvetrain functions include early exhaust valve opening (EEVO) and internal exhaust gas recirculation (iEGR), which help heat the exhaust for improved catalyst efficiency and improved emissions.

Eaton’s hydraulic lash adjuster (HLA) technology optimizes the valvetrain performance by providing precise valve seating over the life of the vehicle. Other benefits include noise reduction and service elimination for manual valvetrain lash settings.

Eaton is a power management company with 2018 sales of $21.6 billion. Its energy-efficient solutions help customers effectively manage electrical, hydraulic and mechanical power more reliably, safely and sustainably. The company is dedicated to improving the quality of life and the environment through the use of power management technologies and services. Eaton employs 99,000 people worldwide, and sells products to customers in more than 175 countries. For more information, visit eaton.com.

Cooper Tire Launches PRO Series™ LHS Steer Tire

First steer tire in Cooper’s PRO Series commercial tire line

FINDLAY, Ohio — Cooper Tire has launched a new long- haul steer (LHS) tire as part of its Cooper PRO Series product line. The tire joins the Cooper PRO Series long haul drive tire introduced last year.

The new steer tire will initially be available in size 295/75R22.5 with other sizes becoming available in June.

The Cooper PRO Series LHS was designed from the ground up to offer low cost of ownership through long miles to removal, fuel efficiency, and design elements to help ensure uniform wear and retreadability, according to Gary Schroeder, executive director of Cooper’s global truck and bus tire business.

The new tire features Cooper’s ECO (Energy Conservation Optimization) technology that combines tire design, compounding and construction to provide an ultra-low rolling resistance tire that both exceeds SmartWay standard requirements by 15 percent and meets the EPA’s greenhouse gas (GHG) emissions requirements set for 2021.

“This steer tire is the new flagship product for Cooper commercial tires,” Schroeder said. “We know the importance of this tire position, and it’s why we designed the tire to perform at a very high level – meeting the demanding needs of long-haul fleets. We purposefully created this tire to give fleets what they are asking for – a low cost of ownership solution to reduce tire program costs and improve a fleet’s bottom line. We’re offering the tire at a price point that makes it a ‘best buy.’ Excellent performance, matched with very competitive pricing, is what fleets are looking for in tires, and we’re delivering with the Cooper PRO Series.”

The Cooper PRO Series LHS provides 18/32nds of tread depth and features a wider footprint than most steer tires on the market – a full inch in many cases. “This provides better traction while promoting longer, more even wear,” said Schroeder. “And, it doesn’t sacrifice fuel economy in the process. When paired with our PRO Series LHD drive tire, that is also SmartWay verified, fleets can maximize fuel economy.”

Schroeder said in order to enhance even wear, the tire has a decoupling groove to minimize shoulder wear. A unique feature on Cooper’s new steer tire is a patent-pending stone ejector design with a stepped groove wall in the tread pattern. This feature helps prevent stone drilling to ensure the integrity of the casing for multiple retreads.

Helping improve tire maintenance is Cooper’s “Wear Square” on the tire’s shoulder ribs. This is a visual indicator, which shows the tread depth through five different evolving image icons. A “square” shows full tread depth, while an “L” shape shows half the tread is left. An icon also shows when the tire should be pulled for retreading. Since the Wear Square is placed on both sides of the tire, it’s also an alignment indicator. If the icons don’t match, the tire technician knows there is an alignment problem or uneven tire issue and can take corrective measures.

The Cooper PRO Series LHS features four-belt steel design construction and an industry-leading seven-year, two-retread warranty. The tire is also warranted for full replacement value for the first 50 percent of treadwear.

“Our warranty showcases the confidence we have in this tire,” said Schroeder. “It’s ready to perform.”

KIRKLAND, Wash. — Kenworth, a PACCAR company, has added two new ratings for the 12.9-liter PACCAR MX-13 engine available for the Kenworth T680, T880 and W990. The PACCAR MX-13 engine brings efficiency and flexibility together into one, high-performance solution, according to Kurt Swihart, Kenworth marketing director.

The first new rating of 405 hp and 1,650 lb-ft of torque provides constant power for line haul applications, enhances integration with the PACCAR Powertrain, and offers increased fuel efficiency.

The second is a multi-torque 455 hp rating with 1,650/1,850 lb-ft of torque that is optimized for fuel-conscious heavy haul fleets and truck operators. This rating provides additional torque in the top two gears while pulling a load up a hill, eliminating the need to downshift.

As a result, the PACCAR MX-13 engine now offers ranges of 405 to 510 hp and 1,450 to 1,850 lb-ft of torque.

“These new PACCAR MX-13 ratings provide enhanced fuel efficiency and lower operating costs for our customers,” Swihart said.

In addition, Kenworth now offers a variable speed fan clutch as on option for the 10.8-liter PACCAR MX-11 engine for the Kenworth T680 and T880. The clutch maximizes engine power to the drive axle, helps prevent under- and over-cooling in all climates, and provides faster warm-up and more efficient air conditioning. The PACCAR MX-11 engine features superior performance, a powerful and lightweight design, and ranges of 355 to 430 hp and 1,250 to 1,650 lb-ft of torque.

“The PACCAR MX engine series has a B10 design life of one million miles in line haul applications. This means 90 percent of PACCAR Engines will log up to one million miles without a major overhaul, almost double the life of a comparable engine,” Swihart said. “The PACCAR MX engine series has been well-accepted by fleets and truck operators in the United States and Canada since introduction nine years ago.”

Peterbilt, another PACCAR company, announced late last year it would offer the new ratings.
