Method and Assembly for Boosting the Brake Force of an Electrohydraulic Motor Vehicle Brake System

摘要

The invention relates to a technique for boosting the brake force of an electrohydraulic motor vehicle brake system in a mode in which, as a result of a mechanical push-through, an actuating force onto a brake pedal acts upon a master cylinder of the brake system. According to an aspect of this technique, the method comprises the steps of: determining a value of a first variable indicating a current deceleration of the vehicle; determining, based on the first variable, a value of a second variable indicating the actuating force; determining, based on the second variable, a required brake boost; and controlling an electromechanical actuator acting upon the master brake cylinder to obtain the required brake boost.

1. Method for boosting the brake force of an electrohydraulic motor vehicle brake system in a mode in which an actuating force on a brake pedal acts upon a brake master cylinder of the brake system by a mechanical push-through, comprising the steps:
determining a value of a first variable that is indicative of a current vehicle deceleration; on the basis of the value of the first variable, determining a value of a second variable that is indicative of the actuating force; on the basis of the value of the second variable, determining a required brake force boost; and controlling an electromechanical actuator, which acts upon the master cylinder, to achieve the required brake force boost.
