Abstract:
Method of controlling a brake system, including a electromechanic parking brake element for detecting the driver's request for brake actuation, an electronic driver assistance device for executing at least one brake-specific driver assistance function, a wheel brake actuator, and an electronic controller, comprising the steps of:transmitting signals from both the electromechanic parking brake element and the electronic driver assistance device to the electronic controller, generating output signals from the electronic controller to the wheel brake actuator, signals representative of an actuating force and actuating force variation, which are preset values for the end value of a tensionary force to be exerted by the actuator device and for a force variation which is to be used by the wheel brake actuator until an end value actuating force is reached, wherein the electronic controller employs a first module for generating output for generating output signals representative of the actuating force and actuating force variation necessary for the execution of the parking brake function induced by the driver, a coordination module for comparing the actuating force variations generated by the first or second module and, in dependence on the sign of the actuating force variations and prioritizing the output signals of either of the first or the second module as output signals for the actuation of the actuator device.
