CONTROL SYSTEM FOR A MOTOR VEHICLE DRIVE.

摘要

A control system for a motor vehicle drive includes an engine control configuration for controlling a variable influencing torque of an engine. A transmission control configuration controls shifting operations of an automatic transmission with a torque converter and transmits an intervention signal to the engine control configuration to carry out an intended shifting operation in a jerk-free and low-wear manner. The transmission control configuration has a circuit configuration for determining a fraction by which the engine torque is to be changed for the shifting operation. The fraction is determined as a function of a transmission input torque obtained from a converter amplification determined by the transmission control configuration and the engine torque determined by the engine control configuration, and as a function of the type of shift. The fraction is transmitted to the engine control configuration as control information for altering the engine torque.
