Control device and method for transferring brake fluid into at least one wheel brake cylinder of a brake system of a vehicle

摘要

A method for transferring brake fluid into a wheel brake cylinder of a brake system of a vehicle includes: controlling a switchover valve, via which a brake circuit having the wheel brake cylinder is connected to a main brake cylinder, into a closed state; subsequently reducing a booster force of a brake force booster, which is exerted upon an adjustable piston of the main brake cylinder; controlling a high-pressure switchover valve to a partially opened state after the reduction of the booster force of the brake force booster; and sucking in brake fluid via the partially opened, high-pressure switchover valve and pumping the brake fluid into the at least one wheel brake cylinder.

1. A method for transferring brake fluid into at least one wheel brake cylinder of a brake system of a vehicle, comprising:
controlling at least one switchover valve into a closed state, wherein at least one brake circuit having the at least one wheel brake cylinder is connected to a main brake cylinder of the brake system via the at least one switchover valve; reducing a booster force of a brake force booster, which is exerted upon at least one adjustable piston of the main brake cylinder, after the controlling of the at least one switchover valve into the closed state; controlling at least one high-pressure switchover valve into an at least partially opened state after the reduction of the booster force of the brake force booster, wherein the at least one brake circuit having the at least one wheel brake cylinder is connected to the main brake cylinder via the at least one high-pressure switchover valve; and sucking in brake fluid via the at least one high-pressure switchover valve which is at least partially opened, and pumping the brake fluid into the at least one wheel brake cylinder.
