Abstract

A speed controlling method for a vehicle comprises obtaining a driving speed limit of a road ahead from a navigation system of the vehicle. A current driving speed of the vehicle is detected and if the current driving speed of the vehicle is greater than the limit ahead, a driver of the vehicle is informed that he must slow down in a distance between the vehicle and a speed measuring device located on the road ahead.

First claim

What is claimed is:

1. A secure controlling method applied to a vehicle, comprising:
obtaining a driving speed limit of a road ahead from a navigation system of the vehicle;
detecting a current driving speed of the vehicle using a speed sensor of the vehicle;
determining whether the current driving speed of the vehicle is greater than the driving speed limit;
when the current driving speed of the vehicle is greater than the driving speed limit, calculating a time duration based on the current driving speed of the vehicle and a distance between the vehicle and a speed measuring device on the road ahead; and
controlling the vehicle to slow down according to the calculated time duration.

2. The secure controlling method according to claim 1 , wherein the distance between the vehicle and the speed measuring device is obtained from the navigation system; or
the distance is calculated by the vehicle using a current position of the vehicle and a position of the speed measuring device that are obtained from the navigation system.

3. The secure controlling method according to claim 1 , wherein the controlling of the vehicle comprises:
controlling a fuel controller of the vehicle to reduce fuel volume supplied to a fuel-line of the vehicle or closing the fuel-line.

4. The secure controlling method according to claim 3 , wherein the controlling of the vehicle comprises:
directly closing the fuel-line of the vehicle when the calculated time duration is less than a preset time duration.

5. The secure controlling method according to claim 4 , wherein the controlling of the vehicle comprises:
firstly reducing a half of the fuel volume supplied to the fuel-line when the calculated time duration is greater than or equal to the pre-set time duration; and
completely closing the fuel-line of the vehicle when a remaining time duration is less than the pre-set time duration, wherein the remaining time duration is calculated by counting down from the calculated time duration.

6. A vehicle comprising:
a storage device;
at least one processor; and
the storage device storing one or more programs, which when executed by the at least one processor, cause the at least one processor to:
obtain a driving speed limit of a road ahead from a navigation system of the vehicle;
detect a current driving speed of the vehicle using a speed sensor of the vehicle;
determine whether the current driving speed of the vehicle is greater than the driving speed limit;
when the current driving speed of the vehicle is greater than the driving speed limit, calculate a time duration based on the current driving speed of the vehicle and a distance between the vehicle and a speed measuring device on the road ahead; and
control the vehicle to slow down according to the calculated time duration.

7. The vehicle according to claim 6 , wherein the distance between the vehicle and the speed measuring device is obtained from the navigation system; or
the distance is calculated by the vehicle using a current position of the vehicle and a position of the speed measuring device that are obtained from the navigation system.

8. The vehicle according to claim 6 , wherein the controlling of the vehicle comprises:
controlling a fuel controller of the vehicle to reduce fuel volume supplied to a fuel-line of the vehicle or closing the fuel-line.

9. The vehicle according to claim 8 , wherein the controlling of the vehicle comprises:
directly closing the fuel-line of the vehicle when the calculated time duration is less than a preset time duration.

10. The vehicle according to claim 9 , wherein the controlling of the vehicle comprises:
firstly reducing a half of the fuel volume supplied to the fuel-line when the calculated time duration is greater than or equal to the pre-set time duration; and
completely closing the fuel-line of the vehicle when a remaining time duration is less than the pre-set time duration, wherein the remaining time duration is calculated by counting down from the calculated time duration.

11. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of a vehicle, causes the processor to perform a secure controlling method, wherein the method comprises:
obtaining a driving speed limit of a road ahead from a navigation system of the vehicle;
detecting a current driving speed of the vehicle using a speed sensor of the vehicle;
determining whether the current driving speed of the vehicle is greater than the driving speed limit;
when the current driving speed of the vehicle is greater than the driving speed limit, calculating a time duration based on the current driving speed of the vehicle and a distance between the vehicle and a speed measuring device on the road ahead; and
controlling the vehicle to slow down according to the calculated time duration.

12. The non-transitory storage medium according to claim 11 , wherein the distance between the vehicle and the speed measuring device is obtained from the navigation system; or
the distance is calculated by the vehicle using a current position of the vehicle and a position of the speed measuring device that are obtained from the navigation system.

13. The non-transitory storage medium according to claim 11 , wherein the controlling of the vehicle comprises:
controlling a fuel controller of the vehicle to reduce fuel volume supplied to an fuel-line of the vehicle or closing the fuel-line.

14. The non-transitory storage medium according to claim 13 , wherein the controlling of the vehicle comprises:
directly closing the fuel-line of the vehicle when the calculated time duration is less than a preset time duration.

15. The non-transitory storage medium according to claim 14 , wherein the controlling of the vehicle comprises:
firstly reducing a half of the fuel volume supplied to the fuel-line when the calculated time duration is greater than or equal to the pre-set time duration; and
completely closing the fuel-line of the vehicle when a remaining time duration is less than the pre-set time duration, wherein the remaining time duration is calculated by counting down from the calculated time duration.
