Condition-based soft-stop function for motor vehicle braking systems
First Claim
Patent Images
1. A control unit, comprising:
- an arrangement for storing a soft-stop function; and
an arrangement for, during deceleration, automatically actuating a braking force reducer to at least partially reduce a braking force acting on a wheel brake, in order to reduce a jerky braking movement, wherein;
an extent of the braking force reduction is a function of at least one of an uphill grade of a roadway, a temperature of the wheel brake, and an amount of wear of the wheel brake.

Abstract
A braking system in particular for motor vehicles, having a soft-stop function, including at least one wheel brake and a control unit which, during deceleration, executes the soft-stop function and which, for this purpose, actuates a braking force reducer which partially reduces the braking force acting on the wheel brake in order to reduce the jerky braking movement. The vehicle may also be safely decelerated in extreme operating conditions when the soft-stop function is implemented in such a way that the extent of the braking force reduction is a function of the uphill grade of the roadway, the brake temperature and/or the amount of wear of the wheel brake.

9. A method for executing a soft-stop function during deceleration of a vehicle, comprising:
causing a control unit storing the soft-stop function as software to at least partially reducing a braking force acting on a wheel brake by automatically actuating a braking force reducer in order to reduce a jerky braking movement, wherein;
an extent of the braking force reduction is a function of at least one of an uphill grade of a roadway, a temperature of the wheel brake, and an amount of wear of the wheel brake. - View Dependent Claims (10)
