Vehicle collision signal detection module mainly comprises digital signal input and clash logic processing capacity, and it adopts the cycle timely checking circuit of 100ms.In the time that vehicle airbag bumps ejection, air bag can be exported square wave or the pulse-width signal that one-period is 100ms, terminal, by logical process, judges after collision happens, understands with limit priority this signal is sent to monitoring backstage by wireless module.Monitor staff recognizes vehicle collision information receiving after this signal, can take relevant rescue measure.
This system is provided with vehicle and wakes control module up, when vehicle is during in inoperative, non-charging, the each controller of vehicle comprises that vehicle monitor terminal is all in power down or dormant state, the arousal function that can possess by wireless modules such as GSM, powers on vehicle monitor terminal, and by waking control module up, wake entire car controller and battery controller up, and further open air-conditioner controller, and open in advance electric automobile air conditioner with before getting on the bus driver, meet the requirement of ride comfort.
This system is provided with vehicle location module, and it passes through Big Dipper positioning chip or GPS chip positioning, and by wireless module, this signal is delivered to backstage, determines the current longitude and latitude of vehicle position.
System possesses Vehicular charging monitoring, according to personal user's needs, Vehicular charging process is monitored.Can check current battery SOC electric weight, charge the estimated time etc.Also can issue by diagnosing protocol instruction, by with the control interface of battery manager BMS, the charging of setting vehicle allows the time period.
When vehicle is in normal operation and when charging, this terminal is powered by Vehicular accumulator cell, battery and whole vehicle state acquisition module and wireless driver module are in running order, be connected for the long distance control system of setting up with main engine plants, meet the period of expansion electric automobile requirement of monitoring in real time of national regulation.Simultaneously by driving behavior being further analyzed to vehicle operating and duration of charging section, service data etc. are deployable.
In the time of vehicle operating, can by backstage automatically to vehicle-mounted VMS BMS MCU controller, read once its software version by diagnosing protocol, and be uploaded to backstage preserve, facilitate the management of the each controller software version of vehicle.
Referring to Fig. 2-4, based on said system, the control method of electric motor car and hybrid vehicle long distance control system is as follows,
After system starts;
System detects whether there is following fault successively, comprise: under (1), non-charged state, whether VMS controller exists fault, and under (2), charged state, whether BMS controller exists fault, (3), under charged state, whether MCU controller there is fault;
If non-fault, timing cycle detects, if the fault of existence is sent to backstage by current failure message;
System closing.
In system operational process, when vehicle collision signal detection module collects collision alarm, by wireless module, this information is sent to backstage at once, and periodically to continue to send vehicle location signal to backstage.
In the time of system closing, for the mobile phone mounted terminal phone of can automatic poking calling a taxi, to wake terminal up, backstage receives opens air-conditioning instruction, and is transmitted to terminal, and monitor terminal is opened ring circuit, annular CMS etc., and controller powers on, and finally carries out air-conditioning opening program.
