In addition, it is not intended to be bound by any express or implied theory presented in the aforementioned technical field, background technology or the following specific embodiments.

[0022] In the following detailed description of the embodiments, many specific details are set forth in order to provide a more thorough understanding of the disclosed technology. However, it is apparent to one of ordinary skill in the art that the disclosed technology can be practiced without these specific details. In other instances, well-known features are not described in detail to avoid unnecessarily complicating the description.

[0023] Terms such as “comprise” and “include” indicate that in addition to the units and steps directly and explicitly stated in the specification, the technical solution of the present application does not exclude the situation where there are other units and steps that are not directly or explicitly stated.

[0024] Hereinafter, various exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings.

[0025] Reference now Figure 1 , Figure 1 is a schematic flow chart of a vehicle driving evaluation method according to an embodiment of the present application:

[0026] like Figure 1 As shown, the vehicle driving evaluation method includes the following steps:

[0027] S1: Providing driving guidance content before the road test. Specifically, before the road test, driving guidance content may be provided to the driver who is about to take the road test. Exemplarily, the driving guidance content may include one or more of the following: explanation video, voice broadcast, and positioning navigation, etc.

[0028] In some embodiments, driving instruction content is provided to the driver in a low-speed driving practice mode, wherein the low-speed driving practice mode is a function designed for driving training, which allows the driver to practice driving operations at a lower speed (e.g., a speed of less than 30 kilometers per hour) in order to better understand and master driving skills. During the low-speed driving practice mode, the driver can better understand the test requirements through the rule explanation video in the driving instruction content. At the same time, the driving instruction content may also include voice broadcasts and graphic instructions, which can provide real-time guidance and feedback to the driver while driving, such as when to turn, when to slow down, etc., so as to help the driver familiarize himself with the test route and operating requirements in advance. In addition, the driving instruction content may also include positioning navigation, such as real-time display of the vehicle position and providing navigation instructions, which helps the driver understand their location during practice and how to drive according to the route requirements.

[0029] In some embodiments, a mobile base station positioning module can be used to provide positioning navigation content. This module usually combines a Bluetooth module and RTK (real-time kinematic differential positioning technology) to ensure the accuracy and reliability of platform communication. The Bluetooth module is responsible for wireless communication with the vehicle system, while RTK exchanges data with a fixed reference station (base station) to correct the vehicle's position data in real time, thereby achieving centimeter-level positioning accuracy.

[0030] The purpose of providing driving guidance content before the road test is to allow drivers to have an overall preview of the route and operating requirements before the actual test, especially to have a clear understanding of the extreme driving positions and techniques involved in the test, so that they can perform operations more confidently and accurately in the test, thereby improving the overall quality of the test.

[0031] S2: During the road test, test-related data is collected, wherein the test-related data includes speed-related data and operation-related data. Specifically, during the road test, collecting test-related data is a key step, which involves comprehensive recording and analysis of the driver's driving behavior. These data usually include speed-related data and operation-related data, wherein the speed-related data may include the speed data and acceleration data of the vehicle. The speed data records the actual driving speed of the vehicle at different time points, while the acceleration data reflects the speed of the vehicle acceleration or deceleration. These data are essential for evaluating the driver's ability to control the vehicle speed. The operation-related data usually may include pedal usage data, brake usage data, and steering wheel angle data. The pedal usage data records the usage of the accelerator pedal and the accelerator pedal, including the pedal strength and operation frequency. The brake usage data records the driver's control of the brake, including the braking strength and the choice of the braking point. The steering wheel angle data records the driver's operation angle and timing of the steering wheel when turning.

[0032] Optionally, these test-related data can be collected by using the CAN (Controller Area Network) bus. The CAN bus is a protocol for internal vehicle communication that allows information to be exchanged between various electronic control units. Through the CAN bus, various operation and status data of the vehicle can be collected efficiently and accurately.

[0033] In addition, digital visualization of test-related data is another important step. This means converting the collected data into digital format and using software tools for visual analysis. For example, the driver's driving behavior can be displayed in the form of charts, graphs or animations, so that the instructor and driver can more intuitively understand the effect of driving operations and areas that need improvement.

[0034] S3: After the road test, the test-related data is analyzed to generate a test analysis report. Specifically, after the driver's road test is completed, the data collected during the test can be analyzed to generate a detailed test analysis report.

[0035] Optionally, the analysis of the test-related data further includes: comparing and analyzing the test-related data with the standard test data. The analysis of the test-related data generally includes the following aspects: speed-related data analysis: This involves a detailed analysis of the vehicle speed data and acceleration data. Through these data, the driver's speed control ability during the test, whether the speed can be appropriately adjusted according to the road conditions and test requirements, and the smoothness of acceleration and deceleration can be evaluated. Operation-related data analysis: This part includes analysis of pedal usage data, brake usage data, and steering wheel angle data. Pedal usage data helps evaluate the driver's control of acceleration and deceleration; brake usage data reveals the driver's control of braking timing and strength; and steering wheel angle data reflects the driver's accuracy and stability when turning. By comparing the test-related data with pre-set standard test data, the gap between the driver's performance and the ideal performance can be quantified.

[0036] In some embodiments, the standard test data may be "master data", i.e., test-related data of master-level drivers. The driver's test-related data is compared with the speed, operation, etc. in the "master data" and analyzed. By analyzing the gap between the driver and the master-level driver, it is helpful to generate an extreme operation analysis report, point out the areas where the driver needs to strengthen practice, design special standardized driving operation exercises, and help the driver continuously improve the accuracy of driving operations, thereby improving driving skills and ultimately meeting the test requirements.

[0037] In some embodiments, after the road test, a playback video of the test and the road test results can also be provided. This not only allows the driver to review his or her driving process, but also increases the transparency of the test.

[0038] In addition, using the technology in this application, automated test tracks can be placed according to the route to achieve smart automated test track tests. At the same time, this high-precision positioning and data analysis technology can also be extended to other extreme maneuvering scenarios to conduct remote guidance and review of driving operations, thereby improving the efficiency of training and testing.

[0039] Through the above comprehensive analysis, the test analysis report can comprehensively reflect the driver's driving skill level and provide valuable feedback to the driver. It also provides a basis for the test institutions to improve the test and training methods.
