Abstract

The invention relates to a device (100) for controlling the power supply of a starter (300) solenoid (200), the input of said device (100) being electrically powered by a voltage source (1). The device (100) comprises a power transistor (16) connected in series with an electromechanical relay (17), and a control signal (7) is supplied at the output of the device (100) when the power transistor (16) and the electromechanical relay (17) switch to an on-state, said signal (7) controlling the power supply of the solenoid (200).

Description

technical field [0001] The invention relates to a control device for the electric power supply of a solenoid of a heat engine starter, in particular for road vehicles comprising an automatic start and stop system. Background technique [0002] The starter is designed to automatically activate the heat engine by means of an electric motor. For this purpose, the starter includes a solenoid, which is an electromechanical relay, which, when supplying electric power, mainly ensures two functions: closing the contactor that allows the electric motor of the starter to supply electric power and enabling the pinion of the electric motor in order to drive the heat engine Meshes with the pinion of the heat engine. The power supply to the starter is controlled upstream by a control device for the power supply. In the case of motor vehicles, the control device for the electric power supply of the solenoid of the starter should at the same time inhibit the risk of improper starting and ...
