Definitions
- the present invention relates to the field of locks for motor vehicles, intended to allow the use of a motor vehicle to only holders of a suitable key.
- a key reading device intended to block the rotation of the barrel in the absence of a key or when a key that is not compatible with the reading device is read, and to allow the rotation of the barrel when a key compatible with the reading device is read
- a switch intended to be driven by the rotation of the barrel to take a first position in which the switch is intended to deactivate a motor of the motor vehicle, and a second position in which the switch is intended to activate the motor.
- the switch and the cylinder receiving the key are usually maintained in different positions.
- the first “STOP” position corresponds to the position where the engine and all electrical equipment are at a standstill.
- the “ON” or “ON” position corresponds to the position allowing to electrically power all the electronic components of the vehicle and keep the engine running.
- the end position “STARTING” or “DEM” makes it possible to ignite the engine and is not intended to be a position in which the barrel and the switch remain locked.
- Maintaining in the different positions is generally performed by a mechanical indexing system.
- the indexing is carried out for example using one or two indexing balls and one or two return springs of the ball or balls. Alternatively, the indexing is performed by one or two flexible blades.
- the indexing system keeps the lock in the ON position as long as the torque exerted on the key is less than a certain predefined value. Said value is typically between 0.15 Nm and 0.4 Nm. When the torque exerted on the key is greater than the preset value, the key goes to another position, and in particular to a position in which the switch extinguishes engine.
- the disadvantage of the previous known lock is that it is very easy to leave the ON position voluntarily or untimely, which can be dangerous when the motor vehicle rolls. Indeed, the key can then be turned into a position in which the engine is stopped, while the operation of the engine is still necessary: when the motor vehicle is traveling at high speed, for example, 90 km / h, or when the motor vehicle is in the overtaking phase of another motor vehicle.
- Inadvertent rotation of the key may for example occur when a driver's knee comes into contact with the key, or because of a very poor road surface causing high vibrations generating a torque greater than the indexing threshold.
- Another cause may also come from the fact that the key is attached to a rather heavy key ring, the weight of the keychain creating sufficient torque to pull the key out of the indexing position.
- the object of the invention is to propose to remedy at least in part the preceding problems.
- a motor vehicle lock of the aforementioned type characterized in that it further comprises: a safety device intended to prevent the switch from leaving its second position towards its first position,
- a speed measuring device for measuring a speed of the motor vehicle and for supplying an activation signal to the safety device when the measured speed exceeds a predetermined threshold so that the safety device prevents the switch from leaving its second position; to reach his first position.
- the predetermined threshold is between 2 km / h and 10 km / h, for example 5 km / h.
- the antitheft device comprises a kinematic chain between the barrel and the switch so that the rotation of the barrel drives the switch, the kinematic chain comprising in particular the barrel and the switch, and the safety device is intended to block a part of the kinematic chain, called biocable part, to prevent the switch from leaving its second position to reach its first position.
- the safety device comprises a locking bolt of the biocable part and a device for actuating the locking bolt.
- the device for actuating the locking bolt is an electromechanical device, and / or a pneumatic device, and / or a hydraulic device.
- the antitheft device further comprises a rotary cam rotatably mounted relative to the body, the rotary cam being intended to be driven by the rotation of the barrel to activate a locking bolt of a steering column of the motor vehicle and wherein the biocable part is the rotating cam.
- the cylinder is intended to take a first position in which the cylinder is intended to receive a key so that the key is read by the reading device while allowing the removal of the key, and a second position in which the cylinder is intended to hold the key.
- the antitheft device further comprises a device for detecting the position of a lever of an automatic transmission of the motor vehicle, the detection device being further intended to supply an activation signal to the device when the lever is detected in at least one predetermined position for the safety device to lock the biocable piece to prevent the barrel from leaving its second position to reach its first position.
- the rotation of the barrel from its first position to its second position is intended to drive the switch from its first position to its second position
- the safety device is further intended to block the biocable piece to prevent the barrel to leave its first position to reach its second position
- an identification device for identifying a driver of the motor vehicle and, in case of identification of the driver, to provide a deactivation signal to the safety device so that the safety device releases the biocable piece to allow the barrel to leave its first position to reach its second position.
