Bosch showcasing wide range of future commercial vehicle technologies at NACV; automated, connected and electric
At the North American Commercial Vehicle Show (NACV) in Atlanta this week, Bosch is showcasing its portfolio of automated, connected and electrified technologies for commercial vehicles.
At NACV, Bosch will debut its 15-inch freely programmable cluster, the largest digital cluster available for the commercial vehicle industry. The optically-bonded display enables future safety and automated solutions as it is easily integrated with advanced driver assistance technologies. Bosch’s 15-inch monitor has two variants, one in landscape mode as a dashboard solution and another in portrait mode as part of a mirror camera system that can replace side mirrors and improve vehicle efficiency by reducing drag.
The Bosch Central Gateway (CGW) enables secure connectivity in commercial vehicles. It is the central communication node that acts as a router for in-vehicle communication and through the connectivity control unit (CCU) to the outside. It is the gate for all data coming into the vehicle and is secure through security functions such as firewall and intrusion detection. ETAS and ESCRYPT (both parts of the Bosch Group) provide the necessary transmission and encryption technologies that ensure functional safety and data security.
Powertrain concepts. At NACV 2017, Bosch is also showcasing several future-focused powertrain concepts engineered to save fuel and money while extending the lives of fleets. The eCity Truck is an innovative diesel hybrid system that is a flexible and scalable solution allowing easy integration of an electric axle (eAxle) into light commercial vehicles to enable the easy conversion of a traditional diesel truck platform to a diesel-electric hybrid truck. The eAxle is a scalable, modular platform with the motor, power electronics, and transmission form one compact unit.
To further reduce fuel consumption, the eCity Truck platform can also integrate 48-volt technology. The Bosch boost recuperation system enables the provision of a 48V electrical accessories as well as energy recovery and smooth, efficient functions such as start-stop.
Bosch is also developing deeply integrated systems for the future that will offer greater fuel savings. The USDepartment of Energy (DOE) awarded a team led by Bosch up to $5 million dedicated to the development and demonstration of a commercially-viable, plug-in hybrid electric vehicle (PHEV) powertrain for medium-duty vehicles typically used in delivery vehicle fleets as part of the Medium-duty Urban Range Connected Extended Powertrain (MURECP) project. At NACV, Bosch will present progress to-date on the project as part of a comprehensive view of the future of the commercial vehicle powertrain.
Progress on the MURECP project includes the advanced dual-planetary gear transmission (e2PG) featuring multiple clutches that reduces fuel consumption by more than 50% on a real-world drive cycle. The design calls for a scalable battery that makes an all-electric driving range feasible, enabling zero local emissions driving in city centers.
Targeting CV delivery trucks, the e2PG powersplit/multi-mode transmission architecture allows for an efficient downsizing of an internal combustion engine via deep integration of two electric motors, resulting in reduced fuel consumption while still maintaining or even improving the overall performance of the vehicle.
Control unit. The Bosch vehicle control unit (VCU) for Commercial Vehicle and Off-road vehicle application enables the development of future technologies, not only for powertrain diversification, but also for automated driving functionalities as well as connected functionalities.
The VCU offers one scalable electric/electronic (E/E) architecture to handle the increased number of calculation-intensive and cross-domain functionalities within continuously evolving efficient, connected and autonomous vehicle.
Thermal management. Whether a traditional internal combustion engine, hybrid-electric or electric vehicle, thermal management has emerged as a key topic for managing vehicle efficiency. At NACV, Bosch will demonstrate technologies it has developed to manage heating and cooling vehicles.
Bosch is working to efficiently manage the heat flow and avoid wasting energy, ultimately improving fuel efficiency of internal combustion engines or increasing the range of electric and hybrid-electric vehicles. The example thermal system will show Bosch fans, pumps and valves for optimizing energy management throughout the entire vehicle—including solutions for highly efficient heating and air conditioning that satisfies all comfort needs.
Actuator. The innovative Electronically Commutated Actuator (ECA) is a Bosch brushless direct current (BLDC) electric motor platform designed specifically for actuation tasks in commercial vehicle applications and environments. Newly designed from the ground up, the ECA actuator performs very precise and high dynamic actuation tasks in the rough environments of engine compartments, chassis and powertrain applications.
ADAS. Bosch’s driver assistance systems actively support the driver to enhance driving comfort and improve safety on the path to automated driving. Bosch has an expansive catalogue in this space, including ultrasonic, radar and video sensors as well as steering solutions.
The latest generation of the Bosch multi-purpose camera (MPC) is a scalable, monocular camera platform for video-based driver assistance systems that make driving safe and more comfortable. The MPC integrates a wide range of driver assistance functions into vehicles using only one sensor.
Another key enabler for driver assistance technology is the Servotwin steering system, a steering technology pre-requisite needed for automated driving. The Servotwin enables automatic steering for functions such as lane-keeping assistance and cross-wind compensation. The Bosch demonstration truck will feature how the Servotwin and multi-purpose camera work together in lane-keeping functions.
