Definitions
- the present invention relates to an electric vehicle antitheft control method, in particular for a motor vehicle, and an antitheft system for implementing the method.
- AVE electric locks
- the AVE 1 receives a V / D lock / unlock command from a cabin control unit (UCH) 3, a vehicle information Vv / stopped and a Vm information / motor stopped.
- UCH cabin control unit
- the information Vv / is derived from the vehicle traveling speed information (designated V vehicle) available in a vehicle brake control unit (UCF).
- V vehicle vehicle traveling speed information
- UCF vehicle brake control unit
- Information Vm / is usually deduced from the rotational speed information of the vehicle engine (designated V engine) available in an engine control unit 4.
- a supply voltage ALIM of the vehicle power supply network is also supplied to the AVE under the control of the unit UCH 3.
- This supply voltage ALIM is generally the +12 V battery voltage of the vehicle and is supplied to the AVE only when the ignition of the vehicle is cut off, which constitutes an additional security, the lock of the lock must not intervene only when the vehicle is in the parking position.
- the information relating to the orders given to the AVE and to the vehicle stop are generally conveyed through a CAN-type onboard bus (acronym for Controller Area Network, in other words Local Network of Controllers).
- Engine shutdown information is typically transmitted over a dedicated wire link to enhance safety in the event of a CAN bus failure.
- the main object of the present invention is to provide a method for controlling an electric antitheft device that guarantees a very high level of operational safety and that is particularly suitable for use in vehicles equipped with the "engine stop / restart” feature. ".
- the control method according to the invention of an electric antitheft device for a vehicle equipped with the engine stop / restart function, the antitheft device operating by blocking the steering column of the vehicle is of the type of those in which a power supply allowing an antitheft lock is provided to the antitheft device only when a power supply circuit of a vehicle engine is in an open state and in which a lock / unlock command, a vehicle stopping information and a Engine stop information is taken into account to allow locking.
- the method also takes account of information representative of the open or closed state of the motor power supply circuit to allow locking only if the motor is at a standstill. and the motor power supply circuit is effectively open.
- the engine stop information is obtained from an engine speed information supplied by a engine control computer.
- said engine stop information is provided by an electric machine mechanically coupled to the engine.
- the engine stop information is provided by an electrical power module electrically coupled to an electric machine mechanically coupled to the engine.
- the invention also relates to an antitheft system for implementing the method briefly described above.
- the antitheft system comprises an electric antitheft device comprising first means able to receive the power supply, the lock / unlock command and the vehicle stopping information and to cause locking / unlocking of the antitheft device by state function of said voltage, order and information.
- the antitheft system also comprises means for producing an authorization / inhibition signal supplied to the first means and authorizing a locking of the antitheft device only on the condition that the engine of the vehicle is at a standstill. and that a motor power supply circuit is actually open.
- the antitheft device comprises:
- a control unit locking means adapted to receive the lock / unlock command of a control unit of the passenger compartment of the vehicle;
- the authorization / lock inhibition signal is received on an input terminal of the control circuit connected to a dedicated port of an engine control computer.
- the authorization / lock inhibition signal is received on an input terminal of the control circuit connected to an output of an AND logic gate, which can be integrated in an alternator, or an alternation starter, mechanically coupled to the motor, both of which inputs respectively receive the engine stop information and information representative of the open or closed state of the motor power supply circuit.
- the authorization / lock inhibition signal is received on an input terminal of the control circuit connected to an output of an AND logic gate adapted to be integrated in an inverter connected to an alternator-starter mechanically coupled to the motor, both of which receive respectively the engine stop information and the information representative of the open or closed state of the motor power supply circuit.
- the invention also relates to an alternator, or an alternator-starter, associated with the antitheft system described briefly above.
- the alternator or alternator-starter, has an output terminal connected to an output of an integrated logic AND gate, both of which receive the engine stop information, respectively. and information representative of the open or closed state of the motor power supply circuit.
- the invention also relates to an inverter associated with the antitheft system described briefly above.
- the inverter has an output terminal connected to the output of an integrated logic AND gate, both of whose inputs receive respectively the motor stop information and the representative information of the open or closed state of the motor power supply circuit.
- FIG.1 is a block diagram of a vehicle antitheft system according to the prior art.
- Fig.2 is a block diagram of an electric vehicle antitheft system according to the invention.
- Fig.3 is a schematic representation of the electric vehicle antitheft system according to the invention.
- the information + APC / gives a logic state 0.
- the power supply circuit of the engine is open, that is to say, when the contact is cut in the vehicle, the information + APC / gives a logical state 1.
- the logic gate 20 shown in FIG. 2 introduces this logic function AND performed on the Vm / and + APC / information to produce a lock enable / disable signal S1 which is provided to the AVE 1.
- the method according to The invention thus provides an additional level of safety over the prior art.
- the engine stop information Vm / is derived from engine speed information supplied by the engine control computer 4.
- the engine stop information Vm / is provided by an electric machine 6 shown in Fig.3 and is mechanically coupled to the engine.
- the electric machine 6 is preferably an alternator-starter
- the engine speed information is available either at the control circuits 7 of the alternator, or at the level of the inverter of the starter, and it is therefore possible to deduce the information Vm / at the level of the machine 6.
- the method of controlling an electric vehicle antitheft device according to the invention has the major advantage of being compatible both with a conventional architecture, where the electric machine 6 is a simple alternator, with a "stop" type architecture. / engine recovery ".
- the signals S2 and S3 are already present at the electrical machine 6, the electrical wiring harness is little changed compared to known systems of the state of the art.
- Fig. 3 shows the detailed structure of an AVE 1.
- electrical locking means 9 of the steering column 10 of the vehicle are controlled by a control unit 1 1 receiving locking / unlocking commands from the cockpit control unit 3 via a bus embedded type CAN 12 (which are also interfaces including braking systems 13 and air bags 14).
- the AVE 1 comprises electrical locking means 15 locking means 9 controlled by a control circuit 16 receiving the signal S1 authorization / inhibition of locking on an input terminal 17.
- the input terminal 17 is connected to an output terminal 18 of the electrical machine 6 connected to the output 19 of the integrated AND logic gate 8.
- the electric machine 6 thus produced, alternator or alternator-starter comprising an inverter, thus has the advantage of being completely compatible with the needs of anti-theft devices of the electromechanical type as described above.
- the exemplary embodiment of the logic function generating the signal S1 of authorization / inhibition of the lock by a logic gate 8, and its integration in the electrical machine 6 simply by means of an additional dedicated output terminal 18, described in FIG. above, are not limiting: other types of signals and / or interface known to those skilled in the art can be implemented and have the same functionality.
