Embodiment 1

[0077] This embodiment provides a vehicle control method, such as figure 1 shown, including the following steps:

[0078] S1. Receive the working state signal of the engine, and judge whether the engine is in the working state. In a specific application, for a vehicle equipped with a keyless start system (Keyless Start System), when the driver enters the vehicle, the keyless start system will detect the electronic key carried by the driver in the car, and the driver presses the Press the start button on the center console or turn the start guide to perform the ignition operation to start the engine. There is no need to insert the key to start the ignition like traditional vehicles. But there are also some safety hazards in this way. For example, the driver suddenly has something to leave the vehicle after starting the engine, because the vehicle is started without a key, and the driver does not need to pull out the key when starting the engine to ignite, and the engine runnin...

Embodiment 2

[0085] like figure 2 As shown, in this embodiment, compared with embodiment 1, step S6a is replaced by:

[0086] S6b. Start timing when the distance between the electronic key and the vehicle exceeds the preset distance, and acquire the duration of the distance between the electronic key and the vehicle exceeding the preset distance.

[0087] S6c. When the duration exceeds the preset duration, send a signal to control the engine to stop working. If the preset duration is not exceeded, continue to count the duration.

[0088] In a specific application, when the driver leaves the vehicle, that is, when the distance between the electronic key and the vehicle exceeds the preset distance, the timer starts when the distance between the electronic key and the vehicle exceeds the preset distance, and obtains the distance between the electronic key and the vehicle exceeds the preset distance. The duration of the distance; when the duration exceeds the preset duration, a signal to co...

Embodiment 3

[0090] On the basis of embodiment 1 or embodiment 2, such as image 3 or Figure 4 As shown, this embodiment also includes after step S4:

[0091] S7. Sending out a control signal for detecting the state of the vehicle door.

[0092] S8. Receive the status signal of the car door, and judge whether the car door is closed.

[0093] S9. If the door is not closed, an alarm control signal is sent. Then return to step S7 and continue to detect the state of the car door. If the door is closed, the detection of the state of the door is ended.

[0094] Preferably, after sending the control signal for controlling the engine to stop working, enter step S7 again, send the control signal for detecting the state of the door again, detect the state of the door, and judge whether the driver closes the door after leaving the vehicle. Of course, it is also possible to enter step S7 after detecting that the driver has left the vehicle to send a control signal for detecting the position of t...

Abstract

The invention provides a vehicle control method, device and system and a vehicle. According to the vehicle control method and device, firstly, a working state signal of an engine is firstly received, and whether the engine is in a working state or not is judged; if the engine is in the working state, a control signal for detecting the state of a vehicle door is transmitted; a state signal of the vehicle door is received, and whether the vehicle door is opened or not is judged; if the vehicle door is opened, a control signal for detecting the position of an electronic key is transmitted; a position detection result signal of the electronic key is received, and the distance between the electronic key and the vehicle is obtained; when the distance between the electronic key and the vehicle exceeds a preset distance, a control signal for controlling the engine to stop working is transmitted. Even when a driver forgets to shut down the vehicle when leaving the vehicle, the engine can automatically stop working after the driver is away from the vehicle, the threat of toxic gas such as carbon monoxide generated by running of the engine to health is avoided, and potential safety hazards are eliminated.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle control method, device, system and vehicle. Background technique [0002] With the development of science and technology, many vehicles are equipped with a keyless start system (Keyless Start System). You don't need to turn the key, but put the key in your bag or pocket. When the driver approaches the vehicle for a certain distance, the keyless start system senses The signal sent by the electronic key carried by the driver will automatically control the unlocking of the door lock. When the driver enters the car, the keyless start system will immediately recognize the electronic key. At this time, the engine can be ignited by simply pressing the start button in the car or turning the start guide plate, making ignition and starting more convenient. [0003] However, the above design has flaws. When the driver is about to leave the car, the engine is usual...
