Abstract

A method and an apparatus for testing a ramp driving performance, and a storage medium, where the method includes: controlling, according to a preset traveling track, an automatic driving vehicle to perform a stopping operation when the automatic driving vehicle is traveling on a ramp to a reference position; obtaining relative position information between an actual stopping position of the automatic driving vehicle and a reference object disposed at the reference position; and determining, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp. The driving performance of the automatic driving vehicle in a special scenario, such as ramp stopping, can be accurately detected, thereby ensuring a driving safety of the automatic driving vehicle in the ramp stopping scenario.

Claims (44)

1. A method for testing a ramp driving performance, comprising:

controlling, according to a preset traveling track, an automatic driving vehicle to perform a stopping operation in a condition that the automatic driving vehicle is traveling on a ramp to a reference position; the traveling track comprises the reference position at which the stopping operation is performed;

obtaining relative position information between an actual stopping position of the automatic driving vehicle and a reference object disposed at the reference position; and

determining, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp, and

the method further comprises:

obtaining first global positioning satellite (GPS) track information during a first preset time period before the automatic driving vehicle is stopped at the reference position; and

determining, according to the first GPS track information, whether a sliding accident occurs in a condition that the automatic driving vehicle is stopped.

2. A nonvolatile memory, wherein the nonvolatile memory has stored thereon instructions that a condition that run on a computer, causes the computer to perform the method of claim 1 .

3. The method of claim 1 , wherein the determining, according to the first GPS track information, whether a sliding accident occurs in a condition that the automatic driving vehicle is stopped, comprises:

determining that a sliding accident occurs in a condition that the automatic driving vehicle is stopped in a condition that it is determined that a switch-back traveling occurs before the automatic driving vehicle is stopped according to the first GPS track information.

4. The method of claim 1 , wherein the determining, according to the first GPS track information, whether a sliding accident occurs in a condition that the automatic driving vehicle is stopped, further comprises:

sending an alarm message in a condition that it is determined that a sliding accident occurs in a condition that the automatic driving vehicle is stopped.

5. The method of claim 1 , further comprising:

setting, according to an operation of a user, the traveling track of the automatic driving vehicle.

6. The method of claim 1 , further comprising:

obtaining, after the automatic driving vehicle starts from the reference position, second GPS track information of the automatic driving vehicle during a second preset time period from starting from the reference position; and

determining, according to the second GPS track information, a ramp starting performance of the automatic driving vehicle.

7. The method of claim 1 , wherein the relative position information comprises distance offset information and angle offset information.

8. The method of claim 7 , wherein the determining, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp, comprises:

determining whether vertical displacement information of the automatic driving vehicle is accurate in a condition that it is stopped on the ramp according to the distance offset information; and

determining whether horizontal offset information of the automatic driving vehicle is accurate in a condition that it is stopped on the ramp according to the angle offset information.

9. The method of claim 8 , wherein the determining, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp, further comprises:

determining that the automatic driving vehicle is accurately stopped on the ramp in a condition that it is determined that both the vertical displacement information and the horizontal offset information of the automatic driving vehicle are accurate in a condition that it is stopped on the ramp.

10. An apparatus for testing a ramp driving performance, comprising: a transceiver, a non-volatile memory, a processor, and a computer program stored on the memory and operable on the processor,

wherein the processor, when running the computer program, is configured to:

control, according to a preset traveling track, an automatic driving vehicle to perform a stopping operation in a condition that the automatic driving vehicle is traveling on a ramp to a reference position; the traveling track comprises the reference position at which the stopping operation is performed;

obtain relative position information between an actual stopping position of the automatic driving vehicle and a reference object disposed at the reference position; and

determine, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp, and

the processor is further configured to:

obtain first global positioning satellite (GPS) track information during a first preset time period before the automatic driving vehicle is stopped at the reference position; and

determine, according to the first GPS track information, whether a sliding accident occurs in a condition that the automatic driving vehicle is stopped.

11. The apparatus of claim 10 , wherein the processor is further configured to determine that a sliding accident occurs in a condition that the automatic driving vehicle is stopped in a condition that it is determined that a switch-back traveling occurs before the automatic driving vehicle is stopped according to the first GPS track information.

12. The apparatus of claim 10 , wherein the processor is further configured to send an alarm message in a condition that it is determined that a sliding accident occurs in a condition that the automatic driving vehicle is stopped.

13. The apparatus of claim 10 , wherein the processor is further configured to set, according to an operation of a user, the traveling track of the automatic driving vehicle.

14. The apparatus of claim 10 , wherein, the processor is further configured to:

obtain, after the automatic driving vehicle starts from the reference position, second GPS track information of the automatic driving vehicle during a second preset time period from starting from the reference position; and

determine, according to the second GPS track information, a ramp starting performance of the automatic driving vehicle.

15. The apparatus of claim 10 , wherein the relative position information comprises distance offset information and angle offset information.

16. The apparatus of claim 15 , wherein the processor is further configured to:

determine whether vertical displacement information of the automatic driving vehicle is accurate in a condition that it is stopped on the ramp according to the distance offset information.

17. The apparatus of claim 16 , wherein the processor is further configured to:

determine whether horizontal offset information of the automatic driving vehicle is accurate in a condition that it is stopped on the ramp according to the angle offset information.

18. The apparatus of claim 17 , wherein the processor is further configured to:

determine that the automatic driving vehicle is accurately stopped on the ramp in a condition that it is determined that both the vertical displacement information and the horizontal offset information of the automatic driving vehicle are accurate in a condition that it is stopped on the ramp.
