Detailed Description
The following examples are intended to illustrate the present disclosure, but are not intended to limit the scope of the present disclosure.
Example 1
The present disclosure provides a vehicle driving examination method, which may be executed by a vehicle driving examination apparatus, which may be implemented in software and/or hardware, and integrated in a vehicle driving examination device. Optionally, the vehicle driving examination device includes, but is not limited to, a computer, a server, and other terminals. In the embodiment of the present disclosure, the vehicle driving examination apparatus will be described in detail as an example.
As shown in fig. 1, the method may include the steps of:
and S110, acquiring current detection data of the current automatic braking system.
The method of the embodiment of the disclosure is applied to a vehicle management platform, and the management platform simultaneously manages a plurality of vehicles registered on the platform. Each vehicle is provided with an automatic braking system (namely AEB), the AEB is an automobile active safety technology and comprises various sensors for collecting vehicle running data and/or state data, the sensors can detect and obtain detection data of the vehicle, and the detection data are periodically uploaded to a management platform. And the management platform analyzes the uploaded detection data to perform safety examination on the vehicle.
In the embodiment of the present disclosure, the current detection data may be understood as detection data to be currently processed by the management platform. The AEB that collects this current inspection data may be understood as the current autobrake system. The current detection data at least comprises: the system identification and the system working code of the current automatic braking system, the speed value and the course angle value of the vehicle which belongs to the detection, the marking information of whether the second braking is finished and the detection time point of the current detection data.
The system identification is used to retrieve system data of the corresponding current autobrake system from a plurality of sets of system data in the cache, e.g., the system identification is a unique code of the autobrake system.
The system working code is used for indicating whether the first brake of the automatic brake system of the vehicle is working or not.
The first braking is an operation in which the current automatic braking system controls the braking system of the vehicle to decelerate, stop, or park the vehicle in motion.
The second brake is an action that a driver controls a brake system of the vehicle to decelerate, stop or park the vehicle in a preset detection time period after the first brake is finished.
And S120, when the detection time point of the current detection data is within a preset detection time period after the first brake is finished and the current detection data comprises the end mark information of the second brake, obtaining the starting vehicle speed value of the first brake from the system data of the current automatic brake system stored in the cache.
First braking, it can be understood that even if the driver does not depress the brake pedal, the AEB is able to automatically apply a control action to the braking system of the vehicle based on the detected data, slowing, stopping or parking the vehicle, thereby protecting the driving for safe travel.
And when the system working code in the current detection data is a preset invalid value, indicating that the first brake of the belonging vehicle finishes working. And when the system working code of the current detection data is a preset invalid value and the previous detection data of the current detection data is a preset valid value, indicating that the current detection data obtained by detection is the detection data after the first brake is finished.
And the end mark information of the second brake is used for indicating that the second brake finishes working.
The disclosed embodiments review the braking effectiveness of the first brake and the second brake during the switching process within the preset detection time period. And if the brake is effective, sending out prompt information.
In the cache, the system data of the AEB of each vehicle is stored, and there is only one system data of the AEB of each vehicle. The system data includes: the system identification, the system operating code, a starting vehicle speed value of the first braking action and an ending course angle value of the first braking action. For example, system data is stored in a HashMap structure in a cache. The disclosed embodiments review the braking effectiveness of the first brake and the second brake during the switching process with reference to the system data.
The preset detection time period is a time period calculated based on a preset detection time period.
In a specific embodiment, the method further comprises the steps of:
and S120a, after the first braking is finished, if the current detection data are determined to be the detection data acquired by the current automatic braking system for the first time, determining that the detection time point of the current detection data is the starting time point of the preset detection time period.
The detection data acquired by the current automatic braking system for the first time can be understood as that when the system working code of the current detection data is a preset invalid value, and the previous detection data of the current detection data is a preset valid value, the current detection data indicates that the current detection data is the detection data acquired by the current automatic braking system for the first time after the first braking is finished. Thus, the detection time point of the current detection data is the start time point of the preset detection time period. That is, it means that the preset detection period is calculated from the detection time point of the current detection data.
In another specific embodiment, before obtaining the starting vehicle speed value of the first brake from the system data of the current automatic brake system stored in the cache when the detection time point of the current detection data is within the preset detection time period after the end of the first brake and the current detection data includes the end mark information of the second brake, the method further includes the following steps:
s120b-1, and determining the system identification and the system working code of the current automatic braking system based on the current detection data.
In an embodiment of the present disclosure, each piece of detection data includes a system identifier of an automatic braking system, and the management platform is configured to distinguish a source of the detection data so as to obtain, from the cache, the system data related to the system identifier. It is to be understood that the system data in the cache is retrieved by the system identification in order to find system data having the same system identification. For example, in the HashMap structure of the system data, the system identifier is stored in Key, and the relevant driving data associated with braking collected by the current automatic braking system is stored in value.
If the same system identification as that in the detection data exists in the system data in the cache, brake analysis can be performed by using the system data and the current detection data to obtain an analysis result.
And S120b-2, if all the cached system parameters do not include the system identification and the system working code is a preset invalid value, generating the system data of the current automatic braking system based on the current detection data.
The current inspection data further includes: a starting vehicle speed value of the first braking action, and an ending course angle value of the first braking action.
If all the cached system parameters do not include the system identifier and the system working code is a preset invalid value, it can be understood that system data identical to the system identifier of the current detection data does not exist in the cache, and the first brake of the automatic brake system of the vehicle to which the current detection data belongs has no working record. System data for the current autobrake system is generated based on the current sensed data.
Optionally, the method further comprises the following steps:
s120b-3, if the cached system parameters include the system identifier and the system working code in the system data is different from the system working code of the current detection data, updating the system data based on the current detection data.
If the system data which is the same as the system identification of the current detection data exists in the cache, and the system working code of the system data is different from the system working code of the current detection data, the current detection data is the first detection data which is uploaded when the working state of the AEB of the vehicle is changed. The current detection data needs to be stored in the corresponding system data in the cache, so as to be used as basic data for brake analysis of subsequent detection data.
And S130, if the starting vehicle speed value and the current vehicle speed value in the current detection data meet a braking prompt condition, generating braking prompt information of the vehicle.
According to the technical scheme provided by the embodiment of the disclosure, the braking effectiveness of the first brake and the second brake in the switching process is examined by using the starting vehicle speed value of the first brake of the vehicle and the current vehicle speed value in the current detection data after the second brake is finished, and if the braking is effective, the braking prompt information of the vehicle is generated. And the first brake and the second brake are respectively checked, so that the checking efficiency is improved, and the intelligent checking function of the vehicle is realized.
Example 2
Since the embodiments of the present disclosure are further optimized based on the above embodiments, the explanations based on the same method components and the same name meanings are the same as those of the above embodiments, and are not repeated herein. The method may comprise the steps of:
and S210, acquiring current detection data of the current automatic braking system.
And S220, when the detection time point of the current detection data is within a preset detection time period after the first brake is finished and the current detection data comprises the end mark information of the second brake, obtaining the starting vehicle speed value of the first brake from the system data of the current automatic brake system stored in the cache.
The first brake is an action that the current automatic brake system controls the brake system of the vehicle to decelerate, stop or park the vehicle in running;
the second brake is an action of controlling a brake system of the vehicle to decelerate, stop or park the vehicle within the preset detection time period.
And S230, obtaining a deceleration value based on the starting vehicle speed value and the current vehicle speed value in the current detection data.
The deceleration value may be understood as the difference between the starting vehicle speed value and the current vehicle speed value. For example, if the starting vehicle speed value is 100 kilometers per hour, the current vehicle speed value is 85 kilometers per hour, and the deceleration value is 15 kilometers per hour.
S240, if the deceleration value is larger than or equal to a preset deceleration threshold value and the current vehicle speed value is smaller than a preset vehicle speed threshold value, generating braking prompt information of the vehicle.
The preset vehicle speed threshold is a safe vehicle speed threshold. For example, continuing with the above example, if the preset deceleration threshold is 10 kilometers per hour and the safe preset vehicle speed threshold is 150 kilometers per hour, then 15 kilometers per hour of the deceleration value is greater than 10 kilometers per hour of the preset deceleration threshold, and 85 kilometers per hour of the current vehicle speed value is less than 150 kilometers per hour of the preset vehicle speed threshold; generating a braking prompt message of the vehicle.
Example 3
Since the embodiment of the present disclosure is further optimized based on the above embodiment 2, the explanation based on the same method composition and the same name meaning is the same as the above embodiment, and will not be described again here.
If on the basis of step S240 in real-time example 2, the method further includes the following steps:
and S310, acquiring the ending course angle value of the first brake from the system data.
The heading angle value refers to an included angle value between a longitudinal axis of the driving direction of the vehicle and the north pole of the earth.
The end course angle value may be understood as the course angle value at the end of the action of the first brake.
And S320, if the ending course angle value and the current course angle value in the current detection data meet the direction alarm condition, generating direction alarm information of the vehicle.
In the embodiment of the disclosure, after the braking alarm information of the vehicle is generated, the change of the driving direction of the vehicle in the switching process of the first brake and the second brake is examined by using the ending course angle value of the first brake and the current course angle value in the current detection data, and if the change meets the direction alarm condition, the direction alarm information of the vehicle is generated.
In a specific embodiment, if the ending course angle value and the current course angle value in the current detection data satisfy a direction alarm condition, generating direction alarm information of the vehicle, including the following steps:
and S320-1, obtaining a current deviation value based on the ending course angle value and the current course angle value.
The current deviation value of the heading angle may be understood as the absolute value of the difference between the ending heading angle value and the current heading angle value. For example, if the ending heading angle value is 60 degrees and the current heading angle value is 55 degrees, then the current deviation value of the heading angle is 5 degrees.
And S320-2, if the current deviation value is greater than or equal to a preset deviation threshold value, generating the direction alarm information.
For example, continuing with the above example, the preset deviation threshold is 3 degrees, and after the braking prompt message of the vehicle is generated, if the current deviation value of 5 degrees of the heading angle is greater than 3 degrees of the preset deviation threshold, the direction alarm message of the vehicle is generated.
