Abstract

The invention relates to a method and device for monitoring brake signals in a vehicle with a gearbox control unit and engine control unit. An error recognition or a plausibility control of said brake signals is carried out. Brake light signals can be received by a gearbox control unit or an engine control unit. Brake light switch signals can be guided by a CAN bus. A cable break or defective contacts or a short-circuit can be considered as errors.
