Abstract
A vehicle includes a drive motor with electrically upstream electric converter, a drive controller generating converter control signals actuating the converter for driving and normal braking operation, and an immobilizer electrically connected between the converter and the drive controller preventing converter control signals which would produce a driving operation of the drive motor from being forwarded to the converter when the vehicle is stopped, in particular at a stop. An alternate regulating device and a monitoring device allow activation of a special braking mode in the presence of an emergency braking command and in the event of which the drive controller is deactivated or at least signal flows of converter control signals of the drive controller to the immobilizer are interrupted, the immobilizer is activated, and converter control signals producing braking operation of the drive motor are transmitted to the converter through the immobilizer by the alternate regulating device.
