  • Drive system for a motor vehicle and method for operating such a drive system
    Patent number: 8676424
    Abstract: A drive system includes at least two drive devices, at least one of which is electric, that drive at least two drive axles, a power electronics system, an energy storage arrangement, and a control device. The control device includes a drive control module for providing a recuperation limiting value for each electric drive, a recuperation control module for combining the recuperation limiting values to form a maximum recuperation total limiting value, and a brake control module for providing a total braking torque requested by a driver or assistance system, such that it derives a recuperation total torque that is less than the recuperation total limiting value and also derives recuperation partial torques for each electric drive. In the case of a total braking torque that is greater than the recuperation total limiting value, the brake control module generates a hydraulic brake pressure and transmits it to the brake system.
