[0029] The 30M# pin of the auxiliary relay 25 is connected to the brake switch 7, the 86M# pin is connected to the 2D# pin of the right-hand handle switch 6, and the 87ME# pin is connected to the 86E# pin of the start relay 8 It should be noted that there are 3B# and 4B# pins in the ABS host 4, and their corresponding functions are CAN-L (low-level signal line in the CAN bus, with a voltage range of 0V to 0.5V) and CAN-H (high-level signal line in the CAN bus, with a voltage range of 2.5V to 3.3V) in CAN communication. The vehicle speed signal is sent to the 5# and 4# pins in the keyless system host 2 through these two pins, so as to ensure that the keyless system host will not lock the front of the vehicle when there is vehicle speed, avoiding the risk of misoperation.

[0030] When the remote control key 1 is within 3 meters of the keyless system host 2, when the start button in the right-hand handle switch 6 is pressed, the 2D# pin outputs a 12V high-level signal to the 6# pin of the keyless system host 2, the 8C# pin of the electronic fuel injection ECU 5, and the 86M# pin of the auxiliary relay 25. At this time, the keyless system host 2 communicates and authenticates the remote control key 1 through a radio frequency signal.

If they are consistent, the vehicle load 16 is powered.

[0031] In some embodiments, the keyless system host generates a challenge code, encrypts it with a first preset algorithm and a first key into final encrypted data, and then sends it to the remote control key, specifically: The keyless system host 2 generates a challenge code, and generates two different random numbers according to the data length of the challenge code, which are a first random number and a second random number; Encrypt the challenge code using a first preset algorithm and a first key to generate encrypted data; Calculate the absolute value N of the difference between the first random number and the second random number, divide the encrypted data into N groups of first sub-encrypted data groups, extract the header information of each group of first sub-encrypted data groups and arrange them in order to establish a verification sequence; The first random number and the second random number are respectively integrated into the first and last ends of the encrypted data to form the final encrypted data, which is then sent to the remote control key 1 together with the verification sequence.

[0032] In some embodiments, the remote control key 1 decrypts the final encrypted data, specifically: The encrypted data is obtained by removing the first random number and the second random number at both ends of the final encrypted data; Calculate the absolute value N of the difference between the first random number and the second random number, and divide the encrypted data into N groups of second sub-encrypted data groups; Decrypt each second sub-encrypted data group using a first preset algorithm and a first key to obtain a corresponding sub-decrypted data group; Extracting the header information of each group of sub-decrypted data groups and arranging them in order to establish a header sequence; Verify whether the similarity between the header sequence and the verification sequence is greater than or equal to a preset similarity threshold. If so, arrange the sub-decryption data groups in order to obtain decrypted data, generate a response code, and then encrypt it with a second preset algorithm and a second key and send it to the keyless system host 2.

[0033] The first preset algorithm can be selected as a symmetric encryption and decryption algorithm or an asymmetric encryption and decryption algorithm; the second preset algorithm can be selected as a symmetric encryption and decryption algorithm or an asymmetric encryption and decryption algorithm.

[0034] After the response code and the challenge code are verified to be consistent, the 8# pin of the keyless system host 2 outputs a 12V high level to the 86H# pin of the power-on relay 15, thereby closing the power-on relay 15 and supplying power to the vehicle load 16. At the same time, the keyless system host 2 sends CAN communication to the 7C# pin and the 9C# pin of the electronic fuel injection ECU5 through the 4# pin and the 5# pin to inform the electronic fuel injection ECU5 to release the engine anti-theft protection; If the brake 7 is pressed and the side stand is retracted while the start button in the right-hand handle switch 6 is pressed, the side stand sensor 22 outputs a signal to the 13# pin of the keyless system host 2, and the electronic fuel injection ECU 5 provides a 12V low-level signal to the 85E# pin of the start relay 8 through the 10C# pin, and the brake 7 supplies power to the 30M# pin of the auxiliary relay 25, thereby supplying power to the 86E# pin of the start relay 8, and the starter motor 9 is started, thereby achieving one-button start; It should be noted that the 1D# pin in the right-hand switch 6 is the AUTO function. When the AUTO button on the right-hand switch 6 is turned on, the 1D# pin will send a 12V high-level signal to the 7# pin of the keyless system host 2, then the leaving home and returning home functions and the automatic switching mode function of the instrument 3 will be activated. The keyless system host 2 is connected to the light sensor 14 through the 1# pin to know the external light conditions. After the leaving home function is activated, when the unlock button of the remote control key 1 is pressed at night, the keyless system host 2 will power the 86L# pin of the headlight relay 23 through the 14# pin so that the headlights will automatically light up. After the returning home function is activated, when the keyless system is turned off when the ignition switch is turned off The system host 2 will supply power to the 86L# pin of the headlight relay 23 through the 14# pin, and the headlights will automatically light up to illuminate the user for a period of time; during normal driving, the keyless system host 2 sends the information of external light through the 4# and 5# pins to the 4A# and 3A# pins of the instrument 3 through CAN communication, so that the instrument 3 can automatically switch between black and daytime modes; if the remote control key 1 is lost during driving, the keyless system host 2 will send the key loss information to the 4A# and 3A# pins of the instrument 3 through the 4# and 5# pins through CAN communication, so that the instrument 3 will issue a pop-up warning, so that the user can find out the key is lost in time.

[0035] In some embodiments, when the unlock button on the remote control key 1 is double-clicked within a certain distance, the 2# pin of the keyless system host 2 will send a high level to the 86G# pin of the seat cushion relay 12, and the 87aG# pin of the seat cushion relay 12 will power the seat cushion solenoid valve 11, thereby achieving the purpose of opening the seat cushion. At the same time, the 10# pin of the keyless system host 2 sends a 12V high level frequency signal to the 86K# pin of the turn signal relay 20, and the 87aK# pin of the turn signal relay 20 will power the turn signal 19 so that the turn signal 19 flashes to indicate that the seat cushion has been opened; Furthermore, when the fuel tank lock button on the control key 1 is clicked within a certain distance, the 3# pin of the keyless system host 2 will send a high level to the 86F# pin of the fuel tank relay 13. At this time, the 87aF# pin of the fuel tank relay 13 supplies power to the fuel tank cap solenoid valve 10, thereby achieving the purpose of opening the fuel tank cap solenoid valve for refueling.

[0036] In some embodiments, when the specific location of the vehicle cannot be found in a parking lot or an underground garage, when the lock button on the remote control key 1 is double-clicked twice, the 9# pin of the keyless system host 2 sends a high-level frequency signal of 12V forty times per minute five times to the 86I# pin of the horn relay 18, and the 87aI# pin of the horn relay 18 powers the horn 17 so that the horn 17 responds five times at a frequency of forty times per minute. At the same time, the 10# pin of the keyless system host 2 sends a high-level frequency signal of 12V forty times per minute five times to the 86K# pin of the turn signal relay 20, and the 87aK# pin of the turn signal relay 20 powers the turn signal 19 so that the turn signal 19 flashes five times at a frequency of forty times per minute, thereby achieving the purpose of reminding the user of the location of the car.
