Abstract
The invention relates to an electric brake system for a motor vehicle and a method for operating the same. In conventional electric brake systems, the energy consumers (6, 8a, 10a, 14b, 16b, 30a, 30b) are connected to the voltage source (24a, 24b) when a switch-on signal is applied. This has the problem associated therewith that, when the switch-on signal is absent for any particular reason, the energy consumers (6, 8a, 10a, 14b, 16b, 30a, 30b) can be disconnected from the voltage source (24a, 24b) during operation of the motor vehicle. This problem is avoided in that the energy consumers (6, 8a, 10a, 14b, 16b, 30a, 30b) remain connected to the voltage source independently of the presence of the switch-on signal. A disconnection of the voltage source from the energy consumers (6, 8a, 10a, 14b, 16b, 30a, 30b) is only triggered by the computer unit (6, 30a, 30b) by driving an ignition-switch device 28.
