Abstract
A method is provided for controlling a drive train (12) of a motor vehicle (10) having an electric drive motor (16, 17), a wheel (26, 27) driven by the electric drive motor (16), and an anti-lock braking system (30) for preventing the wheel from locking (26, 27). The method includes detecting an impending control intervention of the anti-lock braking system (30) and disconnecting a torque-transmitting connection from the electric drive motor (16) to the wheel (26, 27) when an impending control intervention of the anti-lock braking system (30) is detected. Also disclosed are a control device (60), a drive train (12), and a motor vehicle (10) configured to carry out such a method.
Claims11
A method for controlling a drivetrain of a motor vehicle with an electric drive motor, a wheel driven by the electric drive motor, an anti-lock braking system for preventing the wheel from locking, and a plurality of driven axles each being connected in a torque-transmitting manner via a gearbox to an electric drive motor, the method comprising:
- detecting an impending control intervention of the anti-lock braking system;
- disconnecting a torque-transmitting connection from the electric drive motor to the wheel in response to detecting the impending control intervention, wherein disconnecting the torque-transmitting connection includes shifting a gearbox located in the drivetrain between the electric drive motor and the driven wheel to a neutral position;
- and
- sequentially delaying a build-up of brake pressure at a driven axle of the drivetrain until the gearbox is transferred to the neutral position in order to prevent gearbox components and/or the drivetrain from becoming jammed.
