Process and device for controlling a braking force of at least one wheel of a vehicle
First Claim
1. A device for controlling a braking force of at least one wheel of a vehicle, comprising:
- a first arrangement determining a criterion, the criterion at least one of corresponding to a motion of the vehicle and influencing the motion of the vehicle;
a second arrangement determining a wheel variable corresponding to wheel dynamics of a respective wheel of the at least one wheel;
a third arrangement determining, as a function of the criterion, whether a driver-independent brake intervention at the respective wheel is foreseeable;
a fourth arrangement activating actuators assigned to the respective wheel if the driver-independent brake intervention is foreseeable, the actuators being activated for a variable duration of time, the actuators being activated before the driver-independent brake intervention occurs; and
a fifth arrangement determining the variable duration of time as a function of the wheel variable.

Abstract
A device and a process for controlling the braking force at at least one wheel of a vehicle include at least a first arrangement for determining a criterion which describes and/or influences the vehicle movement, a second arrangement for determining a variable which describes the wheel dynamics of the wheel in question, and a third arrangement with which it is determined, at least as a function of the criterion which was determined, whether a driver-independent brake intervention at a wheel is foreseeable. Furthermore, the device and the process contain a fourth arrangement with which a slight activation of the actuators assigned to the wheel, with variable duration, can be performed if the requirement of a foreseeable driver-independent brake intervention is met, this activation occurring before this driver-independent brake intervention. The duration of the slight activation of the actuators is determined at least as a function of the variables which describe the wheel dynamics of the wheel in question.

15. A process for controlling a braking force of at least one wheel of a vehicle, comprising the steps of:
-
determining a criterion, the criterion at least one of corresponding to a motion of the vehicle and influencing the motion of the vehicle; determining a wheel variable corresponding to wheel dynamics of a respective wheel of the at least one wheel; determining whether a driver-independent brake intervention at the respective wheel is foreseeable as a function of the criterion; determining a variable duration of time for activating actuators corresponding to the respective wheel as a function of the wheel variable; and activating the actuators for the variable duration of time if the driver-independent brake intervention is foreseeable, the actuators being activated before a start of the driver-independent brake intervention. - View Dependent Claims (16, 17)
