Description

A kind of intelligence vehicle locking method

Technical field

The invention belongs to technical field of automobile electronic control, be based especially on a kind of intelligence vehicle locking method of automotive networking communication.

Background technology

Along with developing rapidly of automobile industry, the demand of automobile is the most increasing, client is more and more higher to the performance of automobile and the requirement of practicality, such as, if car owner forgets after getting off that car locking or key forgetting are in car, so in car, article (or vehicle) are the most stolen, and car owner is caused certain economic loss by this.

Therefore, on the premise of ensureing the vehicle performance of automobile and each parts quality, main engine plants increase dynamics to the exploitation in terms of the practicality of automobile, which greatly enhances the safety of vehicle, avoid unnecessary loss for car owner.

Summary of the invention

It is an object of the invention to provide a kind of intelligence vehicle locking method based on automotive networking communication.

The object of the present invention is achieved like this, and the operating procedure of intelligence vehicle locking method is as follows:

1) car owner is by the multifunction push key on steering wheel, enters into the comfortableness interface of IPC with the form of LIN communication, carries out automatic car locking function setting；

2) when each OFF state of vehicle, whether ACM sits people in passing through seat sensor detection car, and sends result to control unit；

3) when each OFF state of vehicle, speed (ESC_vehiclespeed) signal all can be sent to other control units by GW by ESC, with this, these control units judge that whether current vehicle speed is as 0km/h；

4) identified by the position of car key and control car door whether self-locking；

5) when BCM detects permission vehicle-locking signal, BCM drives each car door door-lock motor to perform block action, and after having performed this order, will detect the locking state of each door lock:

(1) if each Men Junyi locks, then BCM drives 1 600ms of horn blast, and steering indicating light flashes 1 time, reminds the success of car owner's automatic car locking；

(2) if there being certain unsuccessful to lock, then BCM drives horn blast 2 times, and blow a whistle 800ms every time, and blow a whistle interval 400ms, and steering indicating light flashes 2 times, reminds car owner to fail automatic car locking.

The invention have the advantage that and can improve vehicle general safety performance completely by intelligent car locking.

Detailed description of the invention

Example 1

Pass through multifunction Wheel switch(multi-functional steering wheel switchs) at IPC(combination instrument) carry out automatic car locking function setting, ACM(air bag control unit in interface) whether there is people in detection car；Then ESC(electronic stabilizing control system) by CAN network, GES is sent to BCM(car body controller), ANTENNA(antenna) KEY/FOB(key/smart card detected) at Che Nei still outside car, send result to PEPS(keyless entry and one-key start system), after PEPS processes, result is sent to BCM(car body controller in real time by CAN signal), BCM controls door_lock_motor(door-lock motor) whether lock, and by the prompting host vehicle car locking success the most automatically of the loudspeaker sound.It is implemented as follows:

1, car owner is by the multifunction push key on steering wheel, enters into the comfortableness interface of IPC with the form of LIN communication, carries out automatic car locking function setting: IPC_Autolock=00(function is closed),

IPC_Autolock=01(function is opened), IPC_Autolock =10(invalid value).These data are sent to the controller of all participations automatic car locking function by IPC by CAN network, and this message result is stored in respective EEPROM by these controllers, during each vehicle power supply pattern ON, all will read this value.

2, when each OFF state of vehicle, whether ACM sits people in passing through seat sensor detection car, ACM_pcount=0000 is unmanned in representing car, ACM_pcount=0001 represents that driver's side has people, and ACM_pcount=0010 represents that secondary driver's side has people, can arrange the length of this message according to seat number in car, by that analogy, ACM_pcount=1110 represent there is people on all seats, and ACM_pcount=1111 are invalid value, and by result by GW(gateway) it is sent to other control units.

3, when each OFF state of vehicle, speed (ESC_vehiclespeed) signal all can be sent to other control units by GW by ESC, with this, these control units judge that whether current vehicle speed is as 0km/h.

4, state is worked as: IPC_Autolock=01, ACM_pcount=0000, during ESC_vehiclespeed=0x0000, ANTENNA in PEPS activates car and outside car checks KEY/FOB function, in car, ANTENNA transmits wireless signals to KEY/FOB, KEY/FOB receives signal and feeds back the ANTENNA in car: KEY/FOB_interior=00(is not in car), KEY/FOB_interior=01(is in car), KEY/FOB_interior=10(invalid value)；The outer ANTENNA of car transmits wireless signals to KEY/FOB equally, KEY/FOB receives signal and ANTENNA outer to car feeds back: KEY/FOB_exterior=00(is not outer at car), KEY/FOB_exterior=01(is outer at car), KEY/FOB_exterior=10(invalid value)；When PEPS detects that KEY/FOB is when car is outer, enter the ANTENNA distance outer with car of detection KEY/FOB in real time, when distance KEY/FOB_exterior being detected > 10(is more than 10m, this distance can be configured in IPC comfortableness function) time, PEPS sends signal PEPS_allowautolock=01(and allows automatic car locking, not allowing automatic car locking during PEPS_allowautolock=00, PEPS_allowautolock=10 is invalid value) give BCM.

5, when BCM detects permission vehicle-locking signal, BCM drives each car door door-lock motor to perform block action, and after having performed this order, will detect the locking state of each door lock:

(1) if each Men Junyi locks, then BCM drives 1 600ms of horn blast, and steering indicating light flashes 1 time, reminds the success of car owner's automatic car locking.

(2) if there being certain unsuccessful to lock, then BCM drives horn blast 2 times, and blow a whistle 800ms every time, and blow a whistle interval 400ms, and steering indicating light flashes 2 times, reminds car owner to fail automatic car locking.

6, if car owner has carried out car locking action by KEY/FOB after getting off, PEPS sends PEPS_allowlock=01(PEPS_allowlock=00 and represents the action that do not carries out locking, PEPS_allowlock=10 represents invalid value) signal is to BCM, BCM controls each door lock motor and carries out block action, after guaranteeing that all doors are all locked, by GW by vehicle lock signal (BCM_vehiclelock=01, BCM_vehiclelock=00 vehicle is unlocked, BCM_vehiclelock=10 is invalid value) send to whole CAN network, the control unit of the automatic car locking of all participations will judge automatically, and then do not trigger automatic car locking function.
