ELECTRICAL LOAD FOR A MOTOR VEHICLE
First Claim
1. An electrical load of a motor vehicle, comprising:
- a first electrical vehicle electrical system part for supplying electrical energy from a first vehicle electrical system and a second vehicle electrical system part for supplying electrical energy from a second vehicle electrical system;
a diode element electrically coupled to the first vehicle electrical system part to transfer an activation signal from the first electrical vehicle electrical system part to an electrical energy supply unit provided in the second electrical vehicle electrical system part, the energy supply unit configured to draw electrical energy from the second vehicle electrical system;
wherein the electrical energy supply unit is switchable between an active state where the electrical energy supply unit provides a supply voltage from the second vehicle electrical system, and an idle state where a provision of the supply voltage is suspended; and
wherein the electrical energy supply unit is operable to switch from the idle state to the active state when the activation signal is received from the first vehicle electrical system part.

Abstract
An electrical load, for example and electrical component and/or an electronic component, of a motor vehicle may include a first electrical system part and a second electrical system part for supplying the electrical load with electrical energy from a first vehicle electrical system and a second vehicle electrical system, respectively. The first vehicle electrical system part may be electrically coupled to a diode element for transferring an activation signal to an electrical energy supply unit provided in the second electrical system part. The electrical energy supply unit may be switched between an active state where a supply voltage is provided to the electrical load and an idle state where the supply voltage to the electrical load is suspended.
