Abstract

A vehicle control method includes: obtaining a current location of a vehicle; judging whether the vehicle is in a temporary waiting state or not according to the current location; determining to turn on or off an automatic start/stop function of the vehicle based on the judgment. The control method can distinguish whether the vehicle is waiting for a traffic light or is in a congestion situation, and choose to turn on the automatic start/stop function according to a current road condition, so as to make the automatic start/stop function of the vehicle to be more real-time and accurate, and maximize the reduction of fuel consumption and exhaust emission. A vehicle control device, an in-vehicle system and a vehicle control system are further provided.

Claims

1. A vehicle control method, comprising:

judging whether a vehicle is in a temporary waiting state or not; and

in the case that a judgment result is that the vehicle is in the temporary waiting state, turning off an automatic start/stop function of the vehicle.

2. The method according to claim 1, wherein judging whether the vehicle is in the temporary waiting state or not comprises:

judging whether the vehicle is in the temporary waiting state or not at least according to a current brake frequency of the vehicle.

3. The method according to claim 2, wherein judging whether the vehicle is in the temporary waiting state or not according to the current brake frequency of the vehicle comprises:

in a case that the current brake frequency of the vehicle is greater than a brake frequency threshold, determining that the vehicle is in the temporary waiting state, otherwise, determining that the vehicle is not in the temporary waiting state.

4. The method according to claim 2, wherein judging whether the vehicle is in the temporary waiting state or not at least according to the current brake frequency of the vehicle comprises:

judging whether the vehicle is in the temporary waiting state or not according to the current brake frequency and a current location of the vehicle.

5. The method according to claim 4, wherein judging whether the vehicle is in the temporary waiting state or not according to the current brake frequency and the current location of the vehicle comprises:

in a case that the current brake frequency of the vehicle is greater than a brake frequency threshold and the vehicle dose not wait for a traffic light, determining that the vehicle is in the temporary waiting state, otherwise, determining that the vehicle is not in the temporary waiting state.

6. The method according to claim 1, wherein judging whether the vehicle is in the temporary waiting state or not comprises:

judging whether the vehicle is in the temporary waiting state or not according to a current location of the vehicle.

7. The method according to claim 6, wherein judging whether the vehicle is in the temporary waiting state or not according to the current location of the vehicle comprises:

obtaining real-time traffic information corresponding to the current location based on the current location; and

in the case that the current location indicated by the real-time traffic information is a location of waiting for a traffic light, determining a waiting time period needed by the vehicle to wait for the traffic light from a current time, and in the case that the waiting time period is less than a threshold time, determining that the vehicle is in the temporary waiting state, otherwise, determining that the vehicle is not in the temporary waiting state.

8. The method according to claim 3, wherein in the case that the vehicle is not in the temporary waiting state, the method further comprises:

turning on the automatic start/stop function of the vehicle.

9. The method according to claim 1, wherein before turning off the automatic start/stop function of the vehicle, the method further comprises:

determining that the automatic start/stop function of the vehicle is turned on or off through an automatic mode rather than a manual mode.

10. An in-vehicle system, comprising:

a controller and a processor,

wherein the processor is configured to judge whether the vehicle is in a temporary waiting state or not; and

the controller is configured to turn off an automatic start/stop function of the in-vehicle system in the case that the processor determines that the vehicle is in the temporary waiting state.

11. The in-vehicle system according to claim 10, further comprising a brake information obtaining device configured to obtain a current brake frequency of the vehicle and provide the brake frequency to the processor;

and

the processor is configured to determine whether the vehicle is in the temporary waiting state or not at least according to the brake frequency.

12. The in-vehicle system according to claim 11, further comprising a positioning device configured to obtain a current location of the vehicle and provide the current location to the processor;

and

the processor is configured to determine whether the vehicle is in the temporary waiting state or not according to the brake frequency and the current location.

13. The in-vehicle system according to claim 10, further comprising a positioning device configured to obtain a current location of the vehicle and provide the current location to the processor;

and

the processor is configured to determine whether the vehicle is in the temporary waiting state or not according to the current location.

23. A vehicle control system, comprising a traffic information system and the in-vehicle system according claim 10, wherein the traffic information system sends traffic information to the in-vehicle system, and the in-vehicle system determines to turn on or off an automatic start/stop function of the vehicle according to the traffic information.

24. The vehicle control system according to claim 23, wherein the in-vehicle system is connected with the traffic information system through a network, and the traffic information system is configured to send the traffic information to the in-vehicle system through the network.

25. The vehicle control system according to claim 24, wherein the network comprises at least one of a wired communication network or a wireless communication network.

14. A vehicle control device, comprising:

a judgment unit configured to judge whether a vehicle is in a temporary waiting state or not; and

a control unit configured to turn off an automatic start/stop function of the vehicle in a case that a judgment result is that the vehicle is in the temporary waiting state.

15. The device according to claim 14, wherein the judgment unit is further configured to judge whether the vehicle is in the temporary waiting state or not at least according to a current brake frequency of the vehicle.

19. The device according to claim 14, wherein the judgment unit is further configured to judge whether the vehicle is in the temporary waiting state or not according to a current location of the vehicle.
