Accompanying drawing explanation
Fig. 1 is principle of the invention schematic diagram.
Detailed description of the invention
As shown in Figure 1, the present invention's " a kind of novel digitalisation electric vehicle control system ", is divided into two large divisions:
Body part 1: body part 1 is traditional battery-driven car, comprising:
Central control subsystem 1.1, this part is the part that former Traditional control does not have, this part is the control brain of novel electric vehicle, be responsible for startup and the control of battery-driven car, and the scheduling of bus system data, and the management be responsible for for digital key, in central control subsystem, be divided into 6 submodules.
Center-control submodule 1.1.1, this module in charge for the management of digital key and authentication, be responsible for controlling, for the scheduling of bus system data the source switch of other modules.
Radio communication submodule 1.1.2, this module is equipped with the signalling methods such as bluetooth, WLAN, ZIGBEE, NFC, 2.5G/3G/4G mobile communication, and by above signalling methods, car body can carry out data exchange with smart machine.
Signal light control submodule 1.1.3, analog switch mode before this module changes, change the mode of analog switch modes all on battery-driven car into integrated switch mode, light is controlled by the mode of number switch, because light is controlled by number switch, so inside present system, following function can be had:
Light can be detected by central control subsystem whether to damage or exception;
Can in conjunction with the unblock of vehicle, car locking, seek the instruction that different light flash released by car;
Indicating fault can be sent in conjunction with failure condition.
Switch control rule submodule 1.1.3, adopts the mode of analog switch before this module changes, considerably reduce wire harness on battery-driven car, if traditional battery-driven car there are 10 switches, then there are 20 wire harness cablings, and in our number switch mode, then wire harness can be reduced to 7.
Sound equipment submodule 1.1.4, this module does not exist in traditional battery-driven car, and traditional battery-driven car only has iron loudspeaker, warns for car the use that pipes; And in a system of the invention, sound equipment submodule 1.1.4 have employed digitalisation sound system, adopt differential signal input, have three effects:
Send the tweeting sound of conventional iron loudspeaker;
For the buzzing chimes of doom of traditional anti-theft annunciator;
The audio frequency play for multimedia music exports.
Sensor subsystem 1.1.5, this module does not also exist in traditional battery-driven car, and in a system of the invention, sensor subsystem is equipped with various acceleration pick-up, pressure sensor, has following effect:
Under car locking state, detecting vehicle is static or motion; Whether be illegal movement, and it judges that the grade that stationary vehicle is still moved is dynamic adjustment if can be used as vehicle;
In the unlocked state, detect Velicle motion velocity, dynamic and intelligent adjustment can be done to the power system of vehicle;
In ride, judge whether vehicle is translated into, and carries out power system and automatically closes.
Display sub-module 1.1.6, in traditional battery-driven car, be shown as analogue instrument or segment encode digital meter, in our electric truck system, the power supply unification of display sub-module is controlled by central control subsystem, and can hold segment code digital meter and all digital meter displays such as TFT dot matrix digit instrument and TFT colorful digital instrument.
Electric machine control submodule 1.2, in traditional battery-driven car, electric machine controller is the core controller of battery-driven car, it is except carrying out the driving of motor, the business that also response related key etc. are irrelevant with electric machine control, therefore causing much controlling cable must receive controller from headstock, add unreliable factor, and in our electric truck system, electric machine control submodule is only responsible for driving and the control of motor, its power supply is by center-control submodule United Dispatching, and the rattail needed only needs 12.
Battery management submodule 1.3, in traditional battery-driven car, the electric discharge of storage battery is without management, and the charging of battery is charged by charger completely, because storage battery has aging after using certain number of times, therefore just cannot manage accurately battery, and in a system of the invention, communicated by interference protection bus, can the time of each charging, electric current, change of voltage be recorded and be managed, and battery current consumed in the process of moving, voltage are managed, therefore accomplish the accurate management to battery.
Interference protection data exchange bus 1.4, the concept of interference protection data exchange bus of the present invention, it solves following problem:
The reliability that vehicle travels and safety issue.Present invention employs interference protection data exchange bussing technique, well solving this electromagnetic interference in ride of battery-driven car itself affects problem to data transmission;
Battery management submodule 1.3, electric machine control submodule 1.2, central control subsystem 1.1 in vehicle are connected.
Terminal 2: terminal 2 is the equipment of tape operation system, this equipment can be communicated with the radio communication submodule 1.1.2 of car body by communication (mode such as bluetooth, ZIGBEE, WLAN, NFC), also can pass through wired connection, the bus system of access car body carries out serial communication; The function of this terminal 2 is:
1) as the function of key; When this terminal 2 wirelessly contacts with car body, as being authorized in advance, then can be used as key and use;
2) as authorized equipment, this terminal 2 can be used as control convenience and the fault test set of car body.
The mode of battery-driven car changes and becomes digital control approach by the present invention, thus it is high to avoid traditional analog mode fault rate, and control electric current is large, safe reliability is poor, and the defect of fault detection and maintenance difficult.Meanwhile, by authorizing and being connected, make smart machine as initiation key, control convenience and fault test set, the safety of battery-driven car and the simplicity of maintenance can be substantially increased.
