MOTOR VEHICLE DRIVE DEVICE

摘要

The invention relates to a motor vehicle drive device comprising an internal combustion engine (2) and at least one electrical machine (16), which can be operated as a generator for recuperating electric current from dynamic traveling energy of the motor vehicle. An electronic control device (40) is designed for determining how much braking torque is permitted on the vehicle axle (8), to which the electrical machine is drive-connected or can be drive-connected, according to at least one predetermined driving stability criterion. The electronic control device is also designed for determining the maximally available recuperation torque of the electrical machine serving as the generator that is established based on the difference between the vehicle electric system demands and battery demands placed on the electrical machine and the maximally producible recuperation torque of the electrical machine during the operation of the generator.
