Abstract
A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.
Claims14
A method for controlling a power train of a vehicle immobilized in a parking position, the vehicle being equipped with a parking brake device for immobilizing the vehicle and with at least one electric motor, the method comprising:
- applying the parking brake to an applied position by inserting a blocking finger of the parking brake into an interdental space of a toothed wheel attached connected to a transmission shaft of the electric motor;
- detecting a direction of and/or data for a slope when the parking brake device is in the applied position, including detecting a rotation of the toothed wheel via an angular position sensor to determine the direction of and/or the data for the slope;
- detecting a transition of the parking brake device from the applied position to a released position;
- and
- applying a motor torque setpoint to the electric motor on the basis of the detected direction of and/or the data for the slope.
A device for controlling a power train of a vehicle immobilized in a parking position, the vehicle being equipped with a parking brake device for immobilizing the vehicle and with at least one electric motor, the device comprising:
- a controller configured to apply the parking brake to an applied position by inserting a blocking finger of the parking brake into an interdental space of a toothed wheel attached connected to a transmission shaft of the electric motor
- means for detecting a direction of and/or data for a slope when the parking brake device is in the applied position, the means for detecting including an angular sensor that detects a rotation of the toothed wheel to determine the direction of and/or the data for the slope;
- means for detecting a transition of the parking brake device from the applied position to a released position;
- and
- means for applying a motor torque setpoint to the electric motor on the basis of the detected direction of and/or the data for the slope.
