Abstract

A method and apparatus for braking a vehicle having a vehicle brake system with a brake control device, and an engine whose torque is transmitted via a transmission to driven wheels. When there is a malfunction of the braking system and a demand for a braking operation, the transmission ratio is increased by a transmission control unit, which activates the transmission, to produce increased braking torque at the driven wheels.
