Abstract
The invention relates to a control method for lifting vehicle alarm and a control system thereof and can effectively lift the vehicle alarm. The technical scheme is as follows: the control method for lifting vehicle alarm is characterized in that an engine anti-theft controller judges the validity of an anti-theft chip of a vehicle key and transmits a judgment signal to an engine controller; the engine controller transmits the judgment signal to a vehicle controller; when the vehicle controller verifies that the judgment signal is valid, the vehicle controller leads alarm equipment to lift alarm.
Description
Technical field
The present invention relates to a kind of control method and control system thereof of freeing vehicle alarm.
Background technology
Along with vehicle both domestic and external has been equipped the vehicle body guard against theft and alarm system more and more, when increasing safety, also increased the risk that lost efficacy.On low and middle-grade times vehicle, generally use remote-control key to activate or remove the function of this system at present, when remote-control key because some reason (such as water inlet, do not have electricity, circuit board damage etc.) when causing being suitable for, can't report to the police guaranteeing not reduce to remove under the situation of security arrangement, anti-theft loudspeaker and relevant panalarm can't be closed, can cause car load power shortage gradually thus, make the chaufeur embarrassment simultaneously endlessly.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of control method and control system thereof of freeing vehicle alarm, can effectively realize freeing vehicle alarm.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of control method of freeing vehicle alarm, it is characterized in that: the engine anti-theft controller carries out validity decision to the theftproof chip on the car key, and decision signal is sent to engine controller, engine controller is sent to car body controller with decision signal again, when car body controller verified that this decision signal is legal, car body controller was removed annunciator and is reported to the police.
Be provided with the coil that matches with theftproof chip on the car key, this coil output signal is sent to the engine anti-theft controller.
The engine anti-theft controller is encrypted decision signal and is sent to engine controller, and correspondingly car body controller is decrypted decision signal.
2, a kind of control system that realizes above-mentioned freeing vehicle alarm control method, engine controller connects car body controller, car body controller device taking alarm, it is characterized in that: also have the coil that matches with theftproof chip on the car key, this coil signal mouth sending and receiving motivation anti-theft controller, the engine anti-theft controller is connected with the engine controller communication.
The beneficial effect that the present invention has:
Because the uniqueness of car key theftproof chip coding and the use of encryption communication, the safe class of engine anti-theft is antitheft far above vehicle body, more antitheft far above mechanical key, report to the police by using engine anti-theft to remove vehicle body, effectively improve the safe class of car load, avoided the client can't remove the embarrassment of warning simultaneously.
Description of drawings
Accompanying drawing is the schematic circuit diagram of control system of the present invention.
The specific embodiment
As shown in the figure, theftproof chip 1 is housed on the car key, be provided with the coil 2 that matches with theftproof chip on the car key, this coil signal mouth sending and receiving motivation anti-theft controller U1, engine anti-theft controller U1 is connected with engine controller U2 communication, engine controller U2 meets car body controller U3, car body controller device 3 taking alarm.
When using car key, owing on the car key theftproof chip 1 is housed, coil 2 can be the variation of electromagnetic field with output signal, be sent to engine anti-theft controller U1, engine anti-theft controller U1 judges whether chip is legal, the engine anti-theft controller is encrypted aforementioned decision signal and is sent to engine controller, engine controller U2 is sent to car body controller U3 with this decision signal again by the car load network, car body controller is decrypted checking to decision signal, when this decision signal when being legal, car body controller U3 removes annunciator 3 and reports to the police.
Claims (4)
1, a kind of control method of freeing vehicle alarm, it is characterized in that: the engine anti-theft controller carries out validity decision to the theftproof chip on the car key, and decision signal is sent to engine controller, engine controller is sent to car body controller with decision signal again, when car body controller verified that this decision signal is legal, car body controller was removed annunciator and is reported to the police.
2, the control method of freeing vehicle alarm according to claim 1 is characterized in that: be provided with the coil that matches with theftproof chip on the car key, this coil output signal is sent to the engine anti-theft controller.
3, the control method of freeing vehicle alarm according to claim 2 is characterized in that: the engine anti-theft controller is encrypted decision signal and is sent to engine controller, and correspondingly car body controller is decrypted decision signal.
4, a kind of control system that realizes the control method of the described freeing vehicle alarm of claim 1, engine controller connects car body controller, car body controller device taking alarm, it is characterized in that: also have the coil that matches with theftproof chip on the car key, this coil signal mouth sending and receiving motivation anti-theft controller, the engine anti-theft controller is connected with the engine controller communication.
