Abstract
The controller for a drive train, with engine and transmission controllers has: a detection circuit with which respective driving situations of the motor vehicle and driver's characteristics are determined, and a control device for the clutch which, when the motor vehicle starts, is adapted to the driving situation which is determined and/or the driver's characteristics. When the motor vehicle starts (accelerates from standstill), the control device transfers, to the engine controller, signals with which the engine speed is stored according to stored characteristic curves.
Claims12
A controller for a drive train of a motor vehicle having an engine, a transmission, and an automatically activated clutch, comprising:
- an engine controller configured to control variables influencing a torque of the engine;
- a transmission controller configured to control gear-shifting operations of the automatic transmission and connected to said engine controller for exchanging with said engine controller data permitting a comfortable operation of the motor vehicle;
- a detection circuit connected to said transmission controller for determining a respective driving situation of the motor vehicle and a driver's characteristics;
- a control device for controlling the clutch, said control device being adaptively controlled with respect to one of the driving situation determined by said detection circuit and the driver's characteristics when the motor vehicle starts;
- and
- said control device, when the motor vehicle starts, transferring to said engine controller signals with which the engine speed is controlled according to stored characteristic curves.
