CN202541679U - Electric car keyless starting controller - Google Patents

Abstract

The utility model discloses an electric car keyless starting controller. An identification function module PKE and a three-phase brushless direct current motor controller circuit unit are equipped in the same housing. The PKE function module is mainly composed of an identity recognizing processing unit and a low-frequency emitter. The identity recognizing processing unit comprises a CPU controller, an instruction module and a radio frequency receiver. By adopting an intelligent bidirectional communication means, the electric car keyless starting controller has the advantages of low system cost, low-frequency input high sensitivity, low power consumption and compact equipment arrangement.

Description

Battery-driven car does not have key start-up control device

Technical field

The utility model belongs to the manufacturing of motor vehicle condition control unit, especially Electrical Bicycle vehicle condition control unit field.

Background technology

Electrical Bicycle has environmental protection, advantage conveniently; Electrical Bicycle is popularized day by day becomes the main walking-replacing tool of people in the city; Use the Electrical Bicycle of band remote keyless entering (Remote Keyless Entry RKE) function increasing at present; And vehicle-borne no key start-up control device needs to be provided with separately, and this configuration one side makes that the accommodation space of equipment is bigger, use RKE to need the user to unblank in addition at every turn and lock before all need click remote controller; Relatively trouble, and the possibility that exists quilt to cut sign indicating number, crack.

The utility model content

Above shortcoming in view of prior art; The purpose of the utility model is that a kind of battery-driven car of design does not have key start-up control device; Make it to adopt the mode of not having key operated PKE near formula; The vehicle-mounted control part is arranged in the same housing with the three-phase brushless dc motor controller, to reduce the installing space of equipment.

The purpose of the utility model is to realize through following design.

Battery-driven car does not have key start-up control device, it is characterized in that, recognition function module PKE and three-phase brushless dc motor controller circuitry unit are set in same housing; Said PKE functional module mainly is made up of identification processing unit and low frequencies device; Said identification processing unit comprises cpu controller, instruction module and radio frequency receiver.

The utility model adopts the intercommunication of intelligence, and the equipment arrangement is compact low, and the low coverage recognized patterns is adopted in identification, greatly reduces by the possibility of cutting sign indicating number, cracking, and it is low to have system cost, low frequency input sensitivity height and advantage low in energy consumption.

Description of drawings

Fig. 1 is the structured flowchart of the utility model.

Fig. 2 is the work block diagram of the utility model control setup.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to detail.

Can see in conjunction with Fig. 1 and Fig. 2, recognition function module PKE and three-phase brushless dc motor controller circuitry DK are set in same housing (1); Said functional module PKE mainly is made up of identification processing unit and low frequencies device LREF; Said identification processing unit comprises cpu controller, instruction module and radio frequency receiver.Entire equipment is supplied power by power supply module DY.Three-phase brushless dc motor controller circuitry DK adopts the commercially available conventional electric machine controller of Chengdu Xuguang Science and Technology Co., Ltd; As the rising sun light KZQ-6B1 of section, KZQ-9B1, KZQ-12C, KZQ-15A all can, the control of the keying receiving module PKE of electric machine controller.

Fig. 2 has expressed the mode of operation of communication between PKE functional module and the external world (car owner's key); As car owner during near car body; Identification processing unit receiving end will receive by the signal after the identification of remote-control key emission through radio demodulating, data decode and frame deciphering back accomplish that power supply switches, user instructions such as car light control and warning, acceptor circuit adopts the representative type tropadyne.PKE need not the car owner and sends instruction by on the key remote controller and lock door, but through identification car owner's identity automatically, decipherment distance is 1.8 meters.After the car owner gets off; Vehicle is identification car owner's identity constantly, and when the car owner left 1.8 meters on vehicle, vehicle can't recognize car owner's identity and will lock timely; Guaranteed the safety of vehicle and Che Nei treasure; Even near to have interference unit to disturb also of no avail because the interference of interference unit causes vehicle can't recognize car owner's identity more, vehicle locks door will be more timely.Thereby guaranteed user's property safety.Such design has realized that also the control convenience volume is compact more.

Claims (1)

1. battery-driven car does not have key start-up control device; It is characterized in that; Recognition function module PKE and three-phase brushless dc motor controller circuitry unit are set in same housing; Power supply module DY is power supply with recognition function module PKE with the DC motor controller circuit and is connected, and recognition function module PKE is connected with the DC motor controller circuit.
