Definitions
- the present invention relates to a starting control device of a motor vehicle.
- a motor vehicle comprises a starting control device in the form of a lock comprising a rotor and a stator. Said lock allows the motor vehicle to be started by rotating the rotor by a drive means, for example a key insert.
- the rotor is movable in the stator in typically three angular positions.
- the first position corresponds to a so-called "stop" position corresponding to the stopping of the motor vehicle. In this position, neither the starter nor the electronic equipment inside said vehicle can be powered up.
- the second position corresponds to a position called "contact” enabling the powering of certain electronic equipment of the vehicle and also allowing the unlocking of a portion of the motor vehicle, in particular the steering column.
- the lock is connected to a rotary cam member disposed between the stator and the rotor so that the rotary member can be rotated with the rotor.
- the rotor drives the rotary member to angular position of contact, the steering column is unlocked.
- the rotary member is connected to an intermediate element, such as a zipper, for unlocking a bolt projecting from the steering column. Unlocking is to lift the bolt out of the steering column.
- the powering up of certain equipment is carried out using relays actuated when the rotor is rotated. Said relays make it possible to close one or more electronic circuits supplying electronic equipment.
- the third position corresponds to the so-called “start” position for energizing the starter which puts into operation the engine of the motor vehicle, hereinafter referred to as "engine".
- the starter is powered electronically by the battery of the motor vehicle and puts into operation the engine
- the rotor of the lock rotates the rotary member.
- the assembly formed by the rotor and the rotary member is locked in the angular contact position by means of an indexing ball mounted in the rotary member and received in a locking cavity provided in the stator.
- the locking cavity is configured such that the assembly can be forced to exit the angular contact position and move to the angular start position.
- the indexing system When returning the rotor from the starting angular position to the angular position of contact which corresponds to the normal vehicle running position, the indexing system, composed of the indexing ball and the blocking cavities, may be insufficient for prevent the indexing ball from stopping the locking cavity in the rolling position, due to the inertia of the indexing system.
