Embodiment Construction

[0023] figure 1 A motor vehicle steering system 1 is schematically illustrated with a motor vehicle control device 9 according to the invention for controlling the steering system 1 . The steering system 1 has a steering wheel 3 fastened to an upper steering shaft 2 . The steering wheel angle input at the steering wheel 3 is transmitted via the upper steering shaft 2 and the lower steering shaft 4 to the steering transmission 5, which converts the steering angle into a translation of a toothed rack. The toothed rack is connected via tie rods 6 to steering wheels 7 in contact with the road surface 8 .

[0024] The steering system 1 is controlled by a motor vehicle control unit 9 . The motor vehicle control device 9 is connected to a supply voltage source 10 which supplies the control device 9 and components connected to the control device 9 with power. The motor vehicle control device 9 comprises an electronic switching element 20 and a control unit 30 which can switch the s...

Abstract

The invention relates to a motor vehicle control device (9) for at least one electrical consumer (40) that is to be controlled, comprising an electronic switching element (20) for arrangement in a supply voltage path (12.1) of the consumer (40) and a control unit (30) for controlling the electronic switching element (20), wherein the control unit (30) is designed to provide a control signal for switching the electronic switching element (20) as a function of at least one input signal (38).

Description

technical field [0001] The invention relates to a motor vehicle control device according to the preamble of claim 1 , having a switching function for at least one electrical load controlled by the motor vehicle control device. Background technique [0002] Due to the increasing number of electrical loads in the electrical system of a motor vehicle, it is desirable to limit the current consumption of temporarily unneeded loads so that the state of charge of the vehicle battery is sufficient to run the motor vehicle even after a relatively long service life. One possible way of limiting the quiescent current demand of the control devices in the vehicle electrical system is to provide a standby or sleep mode. This is particularly advantageous for those control devices of the motor vehicle which provide functions which are occasionally required even with the ignition switched off and which must therefore remain permanently connected to the vehicle battery. [0003] In order to ...
