Definitions
- Steering release device for vehicle equipped with electric power steering
- the present invention relates, in general, to motor vehicles equipped with an electric type power steering. It relates, more particularly, to a device for unlocking or unlocking the steering system of such a vehicle, this device intervening after a previous locking or locking of the same steering system.
- Most motor vehicles are equipped with a steering lock device, which is activated, when the vehicle is not in use, to serve as an anti-theft device, preventing the driving of the vehicle.
- the locking of the steering system of a motor vehicle is usually carried out manually by the rotary drive of the steering wheel by the user, even in an angular engagement position. of this locking device, which then performs a mechanical locking of the steering column.
- the reverse operation of unlocking the steering requires in some cases to provide a manual effort, on the steering wheel, without having assistance so that the locking element, which is found in some cases under stress, can be released from its locked position.
- the driver of the vehicle may, in certain cases, not notice that the anti-theft system has remained in the locked position, which will prevent the next start of the vehicle.
- Such a steering unlocking device for a motor vehicle equipped with electric power steering, comprises, on the one hand, a locking mechanism acting on the steering column, or on another part of the steering system, and on the other hand, associated with the electric steering assistance motor, control means receiving signals from at least one triggering event detector and / or vehicle state, so as to control the electric motor assistance and drive the steering column in rotation, or drive in translation or otherwise move another part of the steering system, by the action of this electric motor, until reaching zero torque or effort or a residual torque or effort, almost zero, for which the steering lock mechanism can be released.
- the electric power steering is automatically controlled, to rotate the steering column, or move any part of the steering system, until a value of torque or effort is reached. , acting on the steering locking mechanism, such that unlocking can be done without difficulty.
- the proposed system has a simple and economical structure. On the one hand, it can use sensors and detectors, and an electronic computer, already existing on the vehicle. On the other hand, it does not require any transformation of the vehicle's steering system, and it uses a conventional or existing locking mechanism for the steering column, or another part of the steering system, this mechanism does not even need to be modified or adapted.
- the known unlocking device still has drawbacks or inadequacies, in particular from the point of view of operating safety, and of the adaptation of operation to certain particular situations, this device having no "intelligence". In particular, a situation which presents itself in a relatively frequent manner is not taken into account, namely the case where a steering wheel of the motor vehicle encounters a fixed obstacle, such as a curb, during the procedure. automatic release, before reaching the steering release.
- the present invention therefore aims to improve an unlocking device of the kind previously indicated, so as to adapt its operation to such situations, in order to make this device truly functional and safe.
- the subject of the invention is a steering unlocking device, of the type concerned, for a motor vehicle equipped with an electric power steering, in which the control of the electric assistance motor, for unlocking the steering, is automatically interrupted by the control means, after a predetermined time, in the event that the zero or almost zero torque or effort is not reached after this time.
- the control of the electric assistance motor is automatically reversed by the control means after a first predetermined time, in order to rotate the steering column, or move another part of the steering system, in the opposite direction of the initial direction, until creating a zero or almost zero torque or force on the locking mechanism, or until reaching another predetermined time, this in the case where the zero or almost zero force or torque n 'is not reached after the first predetermined time.
- the invention offers an effective solution even in the case where, during the initial unlocking attempt (the steering being moved in one direction), a wheel of the vehicle would encounter an obstacle, for example abutting against the edge of a pavement.
- the procedure is interrupted, after a certain time, if the unlocking is not obtained with the second direction of rotation of the electric assistance motor, and whatever the cause.
- the invention also takes into account the hypothesis in which, at the time of the request to release the steering, the torque or force on the locking mechanism is already zero or almost zero. In the latter case, the command of the electric assistance motor for unlocking the steering is not carried out (this command becoming unnecessary).
- this device "ignores", at the time of unlocking, what is the torque or the force that applies to this instant.
- the computer will then give the steering system an angular displacement order to the right, then possibly to the left, or vice versa, with preset limit values, until detection of the direction unlocking, but without taking account of the direction to privilege to directly reach the state of release.
- the means control belonging to the device of the invention can be provided to compare the initial angular position of the steering column, or the position of another part of the steering system, that is to say its position at the moment detection of the triggering event, with preset angular positions for locking the steering column by the locking mechanism, or preset positions for locking another part of the steering system, and for controlling the rotation initial of the electric assist motor in a direction corresponding to the shortest movement between the initial position and a blocking position, in order to avoid an attempt to unlock in a reverse direction itself in the necessary sense.
- the device makes it possible to rotate the steering column, or to move any other part of the steering system, in the necessary direction in order to eliminate the residual torque on the locking mechanism, bringing the steering column, or another part of the steering system, to the unlocking position. closer.
- an angle or position sensor for example an absolute sensor giving an angular or other position by reference to a value "zero"
- the triggering event and / or status detector necessary for the direction unlocking device is a key insertion detector. contact or a magnetic card or other similar means used to put the vehicle in the starting state (action of "switching on the ignition").
- the triggering event and / or state detectors generate electrical type signals, which are transmitted to the control means where they are processed and combined, to control the rotation of the steering column by the electric assistance motor, or the setting in motion of another part of the steering system, by electrically supplying this motor with sufficient power to make the torque or force zero or almost zero on the locking mechanism, this mechanism automatically moving to the unlocked position as soon as the torque or force is sufficiently low.
- the control means intervening to control the electric assistance motor by receiving and processing the signals from the triggering event and vehicle state detectors, and from the torque or position sensor, to control the unlocking process. , these are advantageously constituted by an electronic computer.
- This figure shows the usual elements of a motor vehicle steering 2, namely a steering wheel 3 linked to a steering column 4, the end of which remote from the steering wheel 3 carries a pinion 5 engaging with a rack 6, the two ends of the rack 6 being respectively linked, by means of links, to the two steered wheels 7 and 8 of the vehicle concerned.
- the steering 2 comprises a locking mechanism 9, with anti-theft function, which is arranged on the steering column 4, for example under the steering wheel 3. It is, for example, a locking mechanism 9 which is neutralized by the introduction of an ignition key into a contact lock, and which is activated when the ignition key is removed from its lock.
- an electric power motor 10 is provided, with two directions of rotation, the output shaft of which is coupled to the steering column 4, by means of a mechanical transmission 11, so as to transmit an engine torque to it.
- the electric assistance motor 10 is controlled by an electronic computer 12; the latter receives, inter alia, an electrical signal S1 from a resisting torque sensor 13, placed on the steering column 4 between the locking mechanism 9 and the point of attack of the mechanical transmission 11 (not necessarily located at the place illustrated in the drawing).
- the electronic computer 12 also receives an electrical signal S2 from a detector 15 of triggering event, or state, in particular a detector of the presence of the ignition key on the ignition lock, or other equivalent system, this state authorizing the intervention of the release device at the moment of detection of a triggering event.
- the computer 12 receiving and processing the electric signal S2 from the triggering event or status detector 15, will generate, when this signal indicates that the vehicle is in the starting phase, a command from the electric assistance motor 10 up to 'when the steering 2 is released by the locking mechanism 9, this according to a fully automatic procedure.
- the electric assistance motor 10 is powered to rotate in a determined direction of rotation, and with sufficient power to exert a torque on the steering column 4 and allow the release of it.
- the rotation of the steering column 4 will stop, as soon as the unlocking has been observed, or after a predetermined time t.
- the electric assistance motor 10 will be supplied to rotate in the opposite direction of rotation, and with sufficient power to create a torque of rotation on the steering column 4 and then allow its release.
- the reverse rotation of the steering column 4 will stop as soon as this column is released, or after another predetermined time t 'has elapsed.
- a possible warning lamp 14, such as an indicator light, can warn the driver of the vehicle of the impossibility of unlocking the steering 2 at the end of the automatic procedures previously described; the driver can then attempt a manual, traditional release.
- the steering unlocking device described above, is applicable to any motor vehicle equipped with electric power steering, and a locking mechanism for the steering column (or a locking system acting on another part of the steering system. direction). We would not depart from the scope of the present invention, as defined in the appended claims:
- any means of torque measurement not necessarily a torque sensor associated with a torsion bar, or a force sensor;
- a direction position sensor for example an angular position sensor, or a position or displacement sensor of any part of this direction;
