Systems for hybrid vehicles
Hybrid vehicles save fossil fuels by supporting and relieving the diesel drivetrain with an electric drive. Bosch is providing electric motors and control systems for medium- and heavy-duty hybrid CVs.
Electronic Diesel Control (EDC) regulates the functions of the injection system in such a way that the engine provides the demanded engine torque. The injection parameters are constantly matched to the engine and the driving situation. Engines with an electronically controlled diesel system from Bosch combine maximum dynamic performance with minimum fuel consumption and emissions.
- Cleaner and economical engine operation thanks to the rapid adaptation of all injection parameters
Hybrid system for CV
Bosch is developing parallel hybrid drives for medium and heavy commercial vehicles based on existing passenger-car and light-duty platforms. The electric machine enables the parallel electric drive to support the combustion engine. This reduces the required output of the combustion engine and subsequently its fuel consumption and CO2 output.
The required electric energy is re-generated through recuperation during braking or driving downhill, and stored in the battery. In these situations the electric machine works as a generator. The electric machine is controlled by the inverter which converts the direct current from the battery into a three-phase current and sets the required torque and speed of the electric machine. The hybrid system control ensures an optimal split of the power output between the combustion engine and the electric machine.
- Reduction of fuel consumption by 5–6% in HD long-haul operation
- Amortization target: within 3 years
- Purely electric, no-noise start-up
- High start-up torque
- Clearance for restricted areas
- Reduced brake wear
