Abstract
A device for controlling an electro-hydraulic brake system of a vehicle checks if the battery or the alternator forming an electric power source for the electric part of the brake system is in its normal operating condition, and when the battery or the alternator is not in its normal operating condition, lowers the load imposed on the battery, so as to care the battery against a too soon failure. The device may also check if the driver is pumping the brake pedal at a substantial standstill of the vehicle, and when the brake pedal is so pumped, also lowers the load imposed on the battery, so as to care the battery against a useless consumption of the battery.
