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.

Method and device for monitoring brake signals in a vehicle

A method of controlling at least a fifth characteristic operating value of a motor vehicle power train includes the step of performing an emergency adaptation of at least one of the stored clutch-disengagement thresholds during an operating phase of the motor vehicle, if predetermined third conditions are present. The method also includes the step of performing a nonemergency adaptation of at least one of the stored clutch-disengagement thresholds at the end of the operating phase if predetermined fourth conditions are present.

Method and apparatus for the control of characteristic operating values of a power train

Methods and apparatus are taught for controlling the operation of a power train in a motor vehicle (), which may include controlling a clutch actuating mechanism () so as to open a clutch () in a vehicle pull mode. Then, a transmission () may be changed from a first gear position to a second gear position via a neutral position by moving a transmission actuator. At or about the same time, the ignition angle of a spark-ignited combustion engine () is preferably shifted during the gear change step to cause the combustion engine to generate a negative engine torque. As a result, engine speed is decreased when the transmission is disposed in the neutral position and a desired engine torque can be rapidly realized as soon as the transmission actuator is disposed in the second gear position. Thereafter, the clutch is closed again.

Methods and apparatus for operating a motor vehicle

A first characteristic operating value, for example the amount of transmissible clutch torque, in a motor vehicle power train with an engine is controlled by using at least a second characteristic value. The second characteristic value is subject to adaptation, if necessary, during an operating phase of the motor vehicle. The method steps are:
