Electric brake system and method for operating the same
First Claim
1. An electric brake system for a motor vehicle wherein a switch-on signal is initiated, the electric brake system comprising:
- at least one energy consumer;
at least one computer unit;
at least one voltage source;
an ignition-switch device for connecting said voltage source to said energy consumer when said switch-on signal is applied to said device;
said computer unit being connected to said ignition-switch device; and
,said ignition-switch device including circuit means for maintaining a connection between said energy consumer and said voltage source notwithstanding a drop in or a switch-off of said switch-on signal until said computer operates on said circuit means to cause said energy consumer to be disconnected from said voltage source.

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.
