The RKE key comprises MCU, and described MCU is connected with button, display device, RF signal transmitting and receiving circuit and power circuit;
The RKE transceiver module, comprise control module, described control module is connected with and receives and the RF signal transmitting and receiving unit of the command information that demodulation RKE key is sent, the I/O processing unit that is used for communicating by letter, the power supply processing unit for the power supply of RKE transceiver module, the output driver element of output control signal and the COMM unit that communicates with engine control system, and described transceiver module carries out two-way communication by RF signal transmitting and receiving unit and described RKE key;
Air-conditioning system connects described output driver element, and by described output driver element control start/stop;
Engine control system connects described COMM unit, with the two-way communication of described RKE transceiver module, and connects wheel box, gathers gearbox-gear information.
Described output driver element is by the start/stop of the described air-conditioning system of Control.Because the output power of output driver element is limited, and air-conditioning system is directly to be driven by automobile power source, just can utilize the limited power realization of output driver element to the control of air-conditioning system by relay.
Described engine control system communicates by CAN bus and described COMM unit.
The present invention also provides a kind of RKE remote start-up method based on two-way communication that adopts said system to realize, as shown in Figure 4, in turn includes the following steps:
Send the starting engine instruction by described RKE key, described RKE transceiver module authenticates the RKE key after receiving the starting engine instruction; If authenticate illegally, the RKE transceiver module is shown by the RKE key to the information of RKE key return authentication failure;
If it is legal to authenticate, described engine control system gathers gearbox-gear information, if the gear of wheel box is not in neutral gear or park, described engine control system returns the failed information that starts by the RKE transceiver module to the RKE key, shown by the RKE key, if the gear of wheel box is in neutral gear or park, described engine control system control engine is lighted a fire;
The RKE key sends and starts the air-conditioning instruction, and described RKE transceiver module starts described air-conditioning system by the output driver element.
After the engine ignition success, described RKE transceiver module sends the information of engine ignition success to described RKE key, is shown by described RKE key.
After the starting of air conditioner success, described RKE transceiver module sends the information of starting of air conditioner success to described RKE key, is shown by described RKE key.
After the starting of air conditioner success, described RKE key sends the instruction that stops air-conditioning, and described RKE transceiver module stops described air-conditioning system by the output driver element.Like this, after the remote activation air-conditioning, when the user does not plan to enter automobile, can be again mode by Remote air-conditioning is stopped.
After air-conditioning quilt stopped, described RKE transceiver module sent air-conditioning to described RKE key and stops successful information, is shown by described RKE key.
After the engine ignition success, described RKE key sends the instruction of engine kill, described RKE transceiver module makes engine kill by described engine control system, if air-conditioning system starts before the engine kill, the RKE transceiver module stops described air-conditioning system by the output driver element, then makes engine kill by described engine control system.After the remote activation engine, when the user does not plan to drive a car, can pass through the mode of Remote with engine kill.Because air-conditioning need to by driven by engine, therefore before engine kill, also need air-conditioning is stopped.
Behind the engine kill, described RKE transceiver module sends the information of engine kill success to described RKE key, is shown by described RKE key.
In a specific embodiment of the present invention, press RKE remote activation button after, the RKE key is encrypted key information, ciphering process can adopt the mode of frame hopping to carry out, and improves the security of communication.Information after the encryption is baseband signal, then this baseband signal is carried in the RF signal and launches.
The RKE transceiver module at first carries out the signal demodulation after receiving the RF signal that key sends, and gives control module with baseband signal afterwards and decodes.
Remotely controlling vehicle mounted air-conditioning work flow process:
The 1st step: vehicle enters anti-theft modes.In the situation that all are closed, engine-off, luggage case are closed, key is extracted, door is locked, click locking key, enter anti-theft modes;
The 2nd step: press fast the remote control start key in 5 seconds after entering anti-theft modes, and continue 2 seconds;
The 3rd step: the RKE transceiver module is set up with ECM and is communicated by letter;
The 4th step: the RKE transceiver module carries out two-way authentication as the base station with RKE key information and ECM.This step is the committed step of two-wire safety certification.
The 5th step: detect by ECM whether gear is neutral gear behind RKE key and the ECM authentication success, if condition satisfies, then starting engine enters the remote activation pattern, and the RKE key shows engine start information;
The 6th step: press two seconds of locking key, RKE transceiver module control air-conditioning system starts, and simultaneously starting of air conditioner information is fed back to the RKE key.
If more than any one-step conditions of six steps do not satisfy, then withdraw from RKE remote start system program, simultaneously failure information is fed back to the RKE key.
In sum, the present invention communicates by letter by the RKE transceiver module is set up with air-conditioning system with engine control system, on the basis that has guaranteed security, has realized long-range engine start and starting of air conditioner, improves the comfort level of vehicle.
