First Claim
Patent Images
1. Electric motor-driven wheel brake system for a vehicle having front and rear axles each supporting at least one wheel thereon, said system comprising:
- electric motor driven actuators each operatively connected with a respective brake operatively associated with a respective wheel,an electronic control unit connected with the actuators and transmitting drive signals to the electric motor-driven actuators of the brakes assigned to the wheels,said electronic control unit comprising at least one microcomputer by which as a function of at least driver'"'"'s braking command signals to drive the electric motor driven actuators at the front and the rear axle are formed to build up braking force at wheel brakes, and by which, in at least one braking situation, signals are formed first to drive the electric motor driven actuators at the front axle to build up braking force at front wheels and after a braking effect is achieved at the front wheels signals are formed to drive the electric motor driven actuators at the rear axle to build up braking force at the rear wheels.

Abstract
The wheel brakes of each vehicle axle or side or diagonal are supplied with current by a separate voltage source. To reduce the load on the vehicle'"'"'s electrical system, the wheel brakes of a front axle are supplied with current first, and then the wheel brakes of a rear axle are supplied with current.
