Method and device for controlling wheel brakes
First Claim
Patent Images
1. A method for controlling wheel brakes in an electrical braking system of a motor vehicle, comprising the steps of:
- generating control driving signals for valve arrangements for a control of a braking pressure in a first group of the wheel brakes from a first power circuit and for a control of a braking pressure in a second group of the wheel brakes from a second power circuit that is independent of the first group of the wheel brakes; and
detecting a first fault in an area of at least one of the valve arrangements, a pressure supply, and an electrical system of the electrical braking system, wherein;
when a second fault affects those of the wheel brakes supplied by the first power circuit, the control driving signals for one of the valve arrangements are generated, a power for an activation of the one of the valve arrangements originating from the second power circuit.

2. A method for controlling wheel brakes in an electrical braking system of a motor vehicle, comprising the steps of:
-
generating control driving signals for valve arrangements for a control of a braking pressure in one of the wheel brakes from a first power circuit, a braking pressure being provided by at least one of an accumulator and a pump; and
detecting a first fault in an area of at least one of the valve arrangements, a pressure supply, and an electrical system of the electrical braking system, wherein;
when a second fault occurs in one of an accumulator circuit, a pump circuit, and the first power circuit, a valve is activated at a brake actuator of a front one of the wheel brakes, the valve isolating the pump circuit from the accumulator circuit. - View Dependent Claims (5, 7)

9. A computer program for causing a computing unit of a control unit to perform the steps of:
-
generating control driving signals for valve arrangements for a control of a braking pressure in a first group of wheel brakes from a first power circuit and for a control of a braking pressure in a second group of the wheel brakes from a second power circuit that is independent of the first group of the wheel brakes; and
detecting a first fault in an area of at least one of the valve arrangements, a pressure supply, and an electrical system of an electrical braking system, wherein;
when a second fault affects those of the wheel brakes supplied by the first power circuit, the control driving signals for one of the valve arrangements are generated, a power for an activation of the one of the valve arrangements originating from the second power circuit.
