[0020] It should be noted that the ABS host 4 has pins 3B# and 4B#, which correspond to the functions of CAN-L (low-level signal line in the CAN bus, its voltage range is 0V to 0.5V) and CAN-H (high-level signal line in the CAN bus, its voltage range is 2.5V to 3.3V) in CAN communication. The vehicle speed signal is sent to pins 5# and 4# in the keyless host 2 through these two pins, thereby ensuring that the keyless host will not lock the vehicle head when there is vehicle speed to avoid the risk of misoperation.

[0021] Example 2: Based on Example 1, the keyless host 2 is provided with pins 1#, 2#, 3#, 4#, 5#, 6#, 7#, 8#, 9#, 10#, 11#, 12#, 13# and 14#; pin 1# is connected to the light sensor 14, pin 2# is connected to the seat relay 12, pin 3# is connected to the fuel tank relay 13, pin 4# is the communication line of CANH, which is respectively connected to pin 9C# of the electronic fuel injection ECU 5, pin 4B# of the ABS host 4, and pin 4A# of the instrument 3; pin 5# is the communication line of CAN-L, which is respectively connected to the electronic fuel injection ECU 5, 3B# pin of ABS host 4, 3A# pin of instrument, 6# pin is connected to 86E# pin of starter relay 8, 2D# pin of right handlebar switch assembly 6 and 8C# pin of electronic fuel injection ECU5, 7# pin is connected to 1D# pin of right handlebar switch assembly 6, 8# pin is connected to 86H# pin of power-on relay 15, 9# pin is connected to 86I# pin of horn relay 18, 10# pin is connected to 86K# pin of turn signal relay 20, 11# pin is connected to the positive pole of battery 21, 12# pin is connected to the negative pole of battery 21, 13# pin is connected to side stand sensor 22, and 14# pin is connected to 86LH pin of headlight relay 23.

[0022] Example 3: Based on Example 2, the right-hand switch assembly 6 has pins 1D#, 2D#, and 3D#. When the remote control key 1 is within 3 meters of the keyless host 2, when the start button in the right-hand switch assembly 6 is pressed, pin 2D# outputs a 12V high-level signal to pin 6# of the keyless host 2, pin 8C# of the electronic injection ECU 5, and pin 86M# of the auxiliary relay 25. At this time, the keyless host 2 communicates and authenticates the remote control key 1 through a radio frequency signal. The keyless host 2 sends a random challenge code to the remote control key 1. After receiving the challenge code, the remote control key 1 will use a preset key and algorithm to encrypt the challenge code and send the encrypted response code to the keyless host 2. After receiving the response code, the keyless host 2 will use the same key and algorithm to decrypt the response code and then compare it with the previously sent challenge code. Compare and verify if they are consistent. At this time, the 8# pin of the keyless 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 host 2 will send CAN communication to the 7C# pin and 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; if the brake 7 and the side stand are retracted at the same time when the start button in the right-hand handle switch assembly 6 is pressed, the side stand sensor 17 outputs a signal to the 13# pin of the keyless host 2. At this time, the electronic fuel injection ECU5 will provide a 12V low level signal to the 85E# pin of the start relay 8 through the 10C# pin. At the same time, 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 to start, and the starter motor 9 is started, thereby achieving one-button start.

[0023] It should be noted that the 1D# pin in the right-hand switch assembly 6 is the AUTO function. When the AUTO button on the right-hand switch assembly 6 is turned on, the 1D# pin will send a 12V high-level signal to the 7# pin of the keyless 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 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 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, there is no The key 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 host 2 sends the external light information to the 4A# and 3A# pins of the instrument 3 through the 4# and 5# pins via 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 host 2 will send the key loss information to the 4A# and 3A# pins of the instrument 3 through the 4# and 5# pins via CAN communication, so that the instrument 3 will issue a pop-up warning, so that the user can find out that the key is lost in time.

[0024] Example 4: Based on Example 3, when the unlock button on the remote control key 1 is double-clicked within a certain distance, pin 2# of the keyless host 2 will send a high level signal to pin 86G# of the seat cushion relay 12. At this time, pin 87aG# of the seat cushion relay 12 powers the seat cushion solenoid valve 11, thereby achieving the purpose of opening the seat cushion. At the same time, pin 9# of the keyless host 2 sends a 12V high-level frequency signal to pin 86K# of the turn signal relay 20. At this time, pin 87aK# of the turn signal relay 20 powers the turn signal 19, causing the turn signal to flash to indicate that the seat cushion has been opened.

[0025] Furthermore, when the fuel tank lock button on the control key 1 is clicked within a certain distance, the 3# pin of the keyless 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 for refueling.

[0026] Example 5: Based on Example 4, when the specific location of the vehicle cannot be found in the parking lot or underground garage, when the lock button on the remote control key 1 is double-clicked twice, the 9# pin of the keyless 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. At this time, 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 9# pin of the keyless 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. At this time, 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 vehicle's location.
