Abstract
A motor vehicle braking system including at least one electrically actuated parking brake (FP) to be positioned at a wheel, a control unit (UC) configured for generating a command for the parking brake (FP) to apply parking braking or to interrupt the application of parking braking at a first intensity following a first request, wherein the control unit (UC) is also configured for generating a command for the parking brake (FP) to apply parking braking at a second intensity in response to a second request issued after the first request.
Claims10
A braking system for a motor vehicle on a parking space, the vehicle including at least one parking brake (FP) for immobilizing the vehicle on the parking space, wherein the parking space supports the vehicle at a changeable orientation when the motor vehicle is parked thereon, said parking brake having an electrical actuation intended for being positioned at a wheel, and a control unit (UC) that generates a first command to the parking brake (FP) to apply parking braking or to interrupt the application of parking braking at a first intensity (F1) following a first request corresponding to a first inclination of the motor vehicle, and wherein the control unit (UC) generates a second command to the parking brake (FP) to apply parking braking at a second intensity (F2) in response to a second request issued after the first request when a change in inclination of the motor vehicle with respect to the first inclination is predicted.
A method of operation of the braking system fitted to a motor vehicle, wherein the braking system includes at least one parking brake (FP) for immobilizing the vehicle on a parking space, wherein said parking brake has an electrical actuation intended for being positioned at a wheel, and a control unit (UC) configured for generating a first command to the parking brake (FP) to apply parking braking or to interrupt the application of parking braking at a first intensity (F1) following a first request and for generating a second command to the parking brake (FP) to apply parking braking at a second intensity (F2) in response to a second request issued after the first request, the method comprising the steps of:
- following parking of the motor vehicle on the parking space, issuing the first request to activate the parking brake at the first intensity (F1) corresponding to a first inclination of the motor vehicle,
- sending the first command to the parking brake (FP) which applies a parking braking force at the first intensity (F1),
- predicting a change in inclination of the parking space,
- sending the second request to apply the parking braking force at the second intensity (F2, F3), and
- applying the braking force at the second intensity (F2, F3).
