Abstract
A method for detecting a movement of a vehicle that has been shut down in a parked state, including: detecting a movement variable which describes a movement of the vehicle, integrating the movement variable, in a manner dependent on a movement direction of the vehicle, to obtain a movement travel, and, if the movement travel meets a predetermined condition, making a decision on the movement for detection.
Claims11
A method for detecting a movement of a vehicle which is shut down in a parked state, comprising:
- acquiring, by a first wheel rotational speed sensor, a first movement variable which describes the movement of the vehicle,
- acquiring, by a second wheel rotational speed sensor, a second movement variable which describes the movement of the vehicle,
- determining, by a processor, a direction of movement of the vehicle with respect to a movement travel by comparing the first movement variable to the second movement variable,
- integrating, by the processor, the first movement variable and the second movement variable as a function of the direction of movement of the vehicle, and
- deciding, by the processor, on the movement to be detected if the movement travel satisfies a predetermined condition.
A method for retensioning a parking brake which keeps a vehicle which has been shut down in a parked state in a stationary state comprising:
- acquiring, by a first wheel rotational speed sensor, a first movement variable which describes the movement of the vehicle,
- acquiring, by a second wheel rotational speed sensor, a second movement variable which describes the movement of the vehicle,
- determining, by a processor, a direction of movement of the vehicle with respect to a movement travel by comparing the first movement variable to the second movement variable,
- integrating, by the processor, the first movement variable and the second movement variable as a function of the direction of movement of the vehicle,
- deciding, by the processor, on the movement to be detected if the movement travel satisfies a predetermined condition, and
- retensioning of the parking brake on the basis of the detected movement.
A control device for carrying out a method for detecting a movement of a vehicle which is shut down in a parked state, comprising:
- a first wheel rotational speed sensor configured to acquire a first movement variable which describes the movement of the vehicle,
- a second wheel rotational speed sensor configured to acquire a second movement variable which describes the movement of the vehicle,
- a processor configured to:
- determine a direction of movement of the vehicle with respect to a movement travel by comparing the first movement variable to the second movement variable,
- integrate the first movement variable and the second movement variable as a function of the direction of movement of the vehicle, and
- decide on the movement to be detected if the movement travel satisfies a predetermined condition.
