[0045] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0046] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0047] Figure 1 This is a first flowchart of the keyless vehicle control method of the present invention. This embodiment proposes a keyless vehicle control method applied to a tracker, wherein the tracker is connected to the vehicle's key, and the tracker and the key are placed inside the vehicle. The method includes:

[0048] S1. When the vehicle is in the locked state, receive the unlock command from the remote end, and generate a first pin control signal according to the unlock command;

[0049] S2. Pull the unlock pin of the key high according to the first pin control signal, so that the key sends an unlock signal to the vehicle;

[0050] S3. When the vehicle is in the unlocked state, receive a locking command from the remote end and generate a second pin control signal according to the locking command;

[0051] S4. Pull the locking pin of the key high according to the second pin control signal, so that the key sends a locking signal to the vehicle.

[0052] Please refer to Figure 9In this embodiment, the original physical car key (or a copied car key) is obtained. For example, if a car rental company's vehicle model is Toyota Corolla, then only the car key for this model can be selected. Optionally, this car key needs to have at least remote locking and unlocking functionality. The car key is analyzed, specifically including: disassembling the car key casing; using a multimeter to locate the pin positions of the unlock button; using a multimeter to measure the on / off state of the key button to determine the positions of the two pins of the unlock button. For example, these positions are the entry points for triggering the unlocking electrical signal. Of the two pins, one is GND, and the other is a level pin, typically a 3.3V high-level drive; manually shorting the two pins of the unlock button using a jumper wire to observe whether the door unlocking function is triggered; finally, confirming the pin positions corresponding to the unlock button.

[0053] Please refer to Figure 10 In this embodiment, the tracker is illustrated using a Tracker product as an example. The selection of PINs on the Tracker product includes: according to the definition of the unlock pin on the car key, two PINs are required, one GND and one DigitalOutput; a suitable Tracker product is selected, and the corresponding PIN pins are located; an external control circuit is connected; for example, a thin wire is used to connect the GND pin of the Tracker PIN to the GND pin of the unlock button, and the Digital Output PIN to the high-level drive pin of the unlock button. This enables remote control. Specifically: an app is developed on the Tracker product's MCU to control the two PINs used, mainly controlling the DO pin to pull high and low; the Tracker product interfaces with a cloud platform, adding an interaction protocol, allowing control of the Tracker's DO pin via the cloud platform / mobile app, thereby achieving the unlocking function; it can be seen that in this embodiment, the Tracker and car key combination product is installed on the car, ensuring concealed location. Based on this, vehicle unlocking via an app has been achieved, and after developing a Carsharing vehicle sharing function on the app, secure vehicle sharing can be realized.

[0054] As can be seen, in this embodiment, a vehicle is shared with a driver through the sharing function on the remote APP; the driver uses the APP to send an unlocking function, and after the Tracker receives the instruction, it controls the above-mentioned DO pin to pull up the level, triggering the key's unlocking function, thereby realizing the unlocking of the car door; the driver can then conveniently enter the car and start the car with one click.

[0055] The beneficial effect of this embodiment is that, when the vehicle is in a locked state, it receives an unlock command from a remote end and generates a first pin control signal based on the unlock command; it then pulls up the unlock pin of the key according to the first pin control signal, causing the key to send an unlock signal to the vehicle; when the vehicle is in an unlocked state, it receives a lock command from a remote end and generates a second pin control signal based on the lock command; finally, it pulls up the lock pin of the key according to the second pin control signal, causing the key to send a lock signal to the vehicle. This achieves a low-cost, maintenance-free keyless vehicle control solution, which can effectively and conveniently provide traditional vehicles with a vehicle sharing experience based on keyless vehicle control.

[0056] Figure 2 This is a second flowchart of the keyless vehicle control method of the present invention. Based on the above embodiment, before receiving the unlocking command from the remote end, the method includes:

[0057] S01. Short-circuit the ground pin and the level pin of the key with a jumper wire, and obtain the unlocking / locking status of the vehicle;

[0058] S02. Based on the current shorting pin and the current unlocked or locked state, determine the unlocking pin and the locking pin among the shorting pins.

[0059] In this embodiment, if the car key also has function buttons for opening the trunk and starting the engine, the corresponding trunk opening pin and engine starting pin are obtained according to the above method.

[0060] Figure 3 This is the third flowchart of the keyless vehicle control method of the present invention. Based on the above embodiments, before receiving the unlocking command from the remote end, the method includes:

[0061] S03. Connect the grounding pin of the tracker to the grounding pin of the key;

[0062] S04. Connect the first output pin and the second output pin of the tracker to the unlock pin and the lock pin, respectively.

[0063] In this embodiment, as described in the example above, the third and fourth output pins of the tracker are connected to the trunk opening pin and the engine start pin, respectively.

[0064] Figure 4 This is the fourth flowchart of the keyless vehicle control method of the present invention. Based on the above embodiments, before receiving the unlocking command from the remote end, the method includes:

[0065] S05. Connect the tracker to the vehicle;

[0066] S06. Obtain the power supply of the vehicle through the power supply path of the vehicle, and use it as its own power supply.

[0067] In this embodiment, if the tracker has a battery, it is powered by its own battery when the battery is fully charged, and it obtains charging power from the vehicle's power supply when the battery is low.

[0068] In this embodiment, if the tracker does not have a battery, the vehicle's power source draws power.

[0069] Figure 5 This is the fifth flowchart of the keyless vehicle control method of the present invention. Based on the above embodiments, after the tracker and the key are placed inside the vehicle, the method further includes:

[0070] S51. Detect the power status of the key;

[0071] S52. When the power state meets the preset conditions, power is supplied to the key through the power path.

[0072] In this embodiment, if the tracker has a battery, when the key's battery has sufficient power, the key's own battery powers the key. When the key's battery has insufficient power, the tracker's battery level is detected. If the tracker's battery has sufficient power, it powers the key. If the tracker's battery has insufficient power, it obtains charging power from the vehicle's power supply and powers the key.

[0073] In this embodiment, if the tracker does not have a battery, it obtains power from the vehicle's power supply and supplies power to the key when the key's battery is low.

[0074] Figure 6 This is the sixth flowchart of the keyless vehicle control method of the present invention. Based on the above embodiment, after the tracker and the key are placed inside the vehicle, the method further includes:

[0075] S53. Receive a query command sent from a remote end, and send a first data acquisition signal corresponding to the query command to the vehicle through the communication channel with the vehicle to obtain the current first vehicle status data.

[0076] S54. Upload the first vehicle status data to the preset query terminal.

[0077] In this embodiment, the first vehicle status data includes one or more of the following: vehicle location, vehicle speed, vehicle fuel level, vehicle mileage, and vehicle operating parameters.

[0078] Figure 7This is the seventh flowchart of the keyless vehicle control method of the present invention. Based on the above embodiments, after the tracker and the key are placed inside the vehicle, the method further includes:

[0079] S55. Receive a monitoring command sent from a remote end, and send a second data acquisition signal corresponding to the monitoring command to the vehicle through the communication channel with the vehicle to obtain the current second vehicle status data.

[0080] S56. When the second vehicle status data meets the monitoring conditions corresponding to the monitoring instruction, the second vehicle status data is uploaded to the preset monitoring terminal.

[0081] In this embodiment, the monitoring instructions include mileage monitoring instructions, fuel level monitoring instructions, and area monitoring instructions. For example, when the collected mileage data exceeds the preset mileage range of the shared car, the current location of the vehicle is sent to the monitoring terminal.

[0082] Figure 8 This is the eighth flowchart of the keyless vehicle control method of the present invention. Based on the above embodiments, after the tracker and the key are placed inside the vehicle, the method further includes:

[0083] S57, Receive disassembly and assembly instructions sent from the remote end;

[0084] S58. Send disassembly and assembly information corresponding to the disassembly and assembly command to the vehicle through the communication channel with the vehicle, so that the vehicle can display the placement position indication of the tracker and the key and the disassembly and assembly guidance diagram on the vehicle screen.

[0085] In this embodiment, since the tracker and key are placed in a relatively hidden location inside the vehicle, in order to facilitate maintenance by staff, the current placement location of the tracker and key and the disassembly and assembly guide diagram can be displayed on the vehicle's central control screen or the staff's personal device screen via remote triggering.
