Abstract
A motor vehicle electronic computer (10), includes: an electrical power supply device (11) supplying a first regulated electrical voltage V1 and a second regulated electrical voltage V2 greater than V1; control peripherals (13) of the vehicle actuators (30); and a processor (12) connected to the first electrical voltage source, controlling the control peripherals. The computer includes at least one control peripheral (14), including an output switch (141) having to be supplied with an electrical voltage of value V2, and a voltage step-up circuit (140) supplying, on an output port (140b), an electrical voltage of value V2 for the power supply of a control circuit (142) of the output switch from an electrical voltage, on an input port (140a) of the voltage step-up circuit, of a lower value than the value V2. A vehicle including such an electronic computer (10) is also described.
