Abstract
A device for controlling an electro-hydraulic brake system of a vehicle checks if a battery forming an electric power source for the electric part of the brake system is in its normal operating condition, by taking a chance that thevehicle is substantially stopped with a brake pedal not being substantially depressed by a driver, wherein the checking is carried out if the outlet voltage of the battery is lower than a predetermined voltage in a substantially loaded condition by momentarily driving a motor-driven pump forming a pressurized brake fluid source for the hydraulic part of the brake system with at least one wheel being braked by the pressurized brake fluid.
