Automotive drivetrain and drivetrain control method

摘要

The drivetrain of a motor vehicle with an engine, a crankshaft starter-generator, a hydrodynamic torque converter and an automatic gearbox, comprises an overriding drivetrain controller ( 20 ) with a driver and situation recognition ( 31 ), a status controller ( 34 ) and a torque management ( 35 ). The controller carries out the following functions: a start-stop operation, an increase in engine torque, a rolling of the vehicle on a non-engaged drivetrain and a regenerative braking operation.
