  • Fault-detection methods for motor vehicle gearboxes
    Patent number: 8055402
    Abstract: A method for detecting a fault state in an automated motor vehicle gearbox having two parallel branches. Each branch has a clutch and is configured to transmit driving torques from a drive unit to at least one driven wheel of the motor vehicle. The method comprises the steps of sensing whether both clutches are at least partially closed; of sensing the rotational speed of the at least one driven wheel and sensing the rotational speed of a non-driven wheel, and of detection of a fault state if both clutches are at least partially closed, and a difference between the rotational speeds of the wheels is greater than a predetermined reference value.
