An electronic control unit (3) for a motor vehicle includes a microcontroller (30) which controls the operation of an engine of the motor vehicle, a regulator (31) of a voltage delivered to the microcontroller (30) by an electric power source (2), and a voltage step-up device (32) including control elements (321) suitable for activating at least one inductive load (320) coupled to the power source (2), an activation which consists of successive energy accumulations and discharges by the at least one inductive load. The at least one inductive load (320) is shared with at least one second device (4) that is internal or external to the electronic control unit (3), a second device whose operation is controlled by the electronic control unit. A method for controlling at least one inductive load (320) coupled to an electric power source (2) of a motor vehicle is also described. |
