S103: the probability that the first brake performance coordinate is located in fixed vehicle non-faulting region, and root are determined
According to the braking quality of vehicle to be detected described in the determine the probability.
In step s101, first brake parameter may include that brake acceleration and handle pull angle.Vehicle to be detected
In acceleration obtainment unit, angle acquiring unit and control unit are installed.
Control unit obtains the brake acceleration of vehicle to be detected by acceleration obtainment unit；Control unit passes through angle
The handle that acquiring unit obtains vehicle to be detected when pulling brake handle pulls angle.
Here it is possible to obtain multiple first brake parameters of vehicle to be detected.The first brake parameter of acquisition is more, detection
Accuracy rate when braking quality is higher.
In specific implementation, when user pulls the brake handle of vehicle to be detected to brake every time, control unit

In step s 102, control unit is according to multiple first brake parameters of acquisition, respectively with acceleration and the handle of braking
Pulling dynamic angle is abscissa and ordinate, determines that the first brake performance of each first brake parameter is sat in a coordinate system
Mark.
Here, angle and brake acceleration can also be pulled as abscissa and ordinate using handle respectively, determined each
The first brake performance coordinate of first brake parameter.
In specific implementation, the acceleration direction of vehicle is positive direction when can select brake, and brake handle is not pulled
When present position be 0 °, first brake performance coordinate can be specifically determined in two-dimensional Cartesian coordinate system.According to acceleration
Direction it is found that first brake performance coordinate the coordinate system first quartile.It should be understood that first brake performance coordinate exists
The position of the coordinate system can be determined according to the acceleration direction of vehicle when selected brake.

Corresponding relationship.Specifically, in vehicle non-faulting region, when the acceleration that brakes determines, handle pulls angle corresponding one to take
It is worth range；Similarly, when handle pulls angle to determine, the corresponding value range of brake acceleration.
Similarly, the second corresponding relationship of brake acceleration and handle pulling angle in vehicle trouble region can be determined.
Control unit saves above-mentioned first corresponding relationship and the second corresponding relationship, gets multiple the when control unit determines
When one braking parameters, it can determined according to the first corresponding relationship and the second corresponding relationship non-positioned at vehicle in first brake parameter
Number in fault zone.
Below above-mentioned braking quality detection method, braking quality detection will be specifically introduced by a feasible embodiment
The step of method includes:
Step 1:MCU obtains multiple brake acceleration of vehicle to be detected by acceleration transducer, and passes through angle
Sensor obtains handle corresponding with brake acceleration and pulls angle.
Step 2:MCU pulls angle according to multiple brake acceleration and handle, pulls angle as abscissa using handle, to stop
Vehicle acceleration is that ordinate determines braking quality coordinate in two-dimensional Cartesian coordinate system.
Step 3:MCU determines the number that braking quality coordinate is located in fixed vehicle non-faulting region.
Step 4:MCU according to be located at fixed vehicle non-faulting region in braking quality coordinate number and brake
The total number of performance coordinate calculates braking quality coordinate and is located at the probability in fixed vehicle non-faulting region.
Whether the probability that step 5:MCU judgement is calculated is more than predetermined probabilities threshold value；If the probability being calculated is more than
Predetermined probabilities threshold value then judges that the braking quality of vehicle to be detected is good；If the probability being calculated is less than predetermined probabilities threshold
Value, then judge that the braking quality of vehicle to be detected is poor.

5th determining module, for the region in boundary curve figure to be determined as vehicle non-faulting region.
8. braking quality detection device according to claim 5 characterized by comprising third obtains module, the 6th really
Cover half block and judgment module；
The third obtains module, being located in fixed vehicle non-faulting region for obtaining first brake performance coordinate
Number；
6th determining module, for according to the first brake performance coordinate being located in fixed vehicle non-faulting region
It is non-to determine that the first brake performance coordinate is located at fixed vehicle for the total number of number and the first brake performance coordinate
Probability in fault zone；
The judgment module, the first brake performance coordinate for judging determining are located at fixed vehicle non-faulting region
Whether interior probability is more than predetermined probabilities threshold value；If being more than predetermined probabilities threshold value, the brake of the vehicle to be detected is judged
It can be good；If being less than predetermined probabilities threshold value, judge that the braking quality of the vehicle to be detected is poor.
9. a kind of electronic equipment characterized by comprising processor, memory and bus, the memory are stored with the place
The executable machine readable instructions of device are managed, when electronic equipment operation, pass through bus between the processor and the memory
Communication executes the braking quality inspection as described in Claims 1-4 is any when the machine readable instructions are executed by the processor
The step of survey method.
10. a kind of computer readable storage medium, which is characterized in that be stored with computer journey on the computer readable storage medium
Sequence executes the step of the braking quality detection method as described in Claims 1-4 is any when the computer program is run by processor
Suddenly.
