Background technique

With the gradual popularization of cars and the rapid development of information technology, cars are not only used as a means of transportation, but also become an important life scene for users to pursue a comfortable experience.

Turning is a driving state that often occurs during vehicle driving. When turning, if the speed, gear position, and accelerator of the vehicle are not well coordinated with the steering angle, it is easy to make operation errors, and even cause rollover due to centrifugal force in severe cases. For a certain type of vehicle, if you start turning at the same speed, the greater the turning angular velocity, the greater the change in the direction of the vehicle's inertial motion. Therefore, when the speed is fast, the turning angle per unit time cannot be too large to ensure safety. When the speed When it is relatively slow, the turning angle per unit time can be relatively large, that is to say, the maximum turning angle speed to ensure driving safety decreases with the increase of vehicle speed. Steering a vehicle requires a number of operations to work together.

A Head Up Display (Head Up Display, hereinafter referred to as HUD) can project an important image interface on the front windshield of the vehicle 110 by using the principle of optical reflection. Since the front windshield is basically level with the driver's line of sight, when the driver looks forward through the projection area of the HUD, the observation of the external environment will not be affected. Therefore, the HUD does not need to look down to check the relevant information, and always keeps observing the state in front of the vehicle, avoiding the potential safety hazard caused by the distraction of the driver. The head-up display sub-module 246 can generate a head-up display interface containing driving suggestions, and display it to the user through the reflective area of the front windshield of the vehicle 110 . The driving reminder is given to the user in a more direct way, which improves the user's reaction speed. The head-up display interface can show driving suggestions in a concise image, which is convenient for the driver to understand the driving suggestions in time and make correct operations.

At the same time, the vehicle driving data during the turning process can also be saved as historical data for subsequent analysis.

The embodiment of the present invention also provides a method for processing vehicle driving data. The vehicle driving data processing method can be executed by the vehicle driving data processing device 200 in the above embodiment, so as to ensure the safe driving of the vehicle 110 .

Vehicle driving data includes any one or more of the following: driving speed, accelerator state, gear state, brake state, etc., and other types of data can also be requested when necessary. For example, the corresponding driving data reading request can be sent according to the type of data required for the attitude estimation calculation. The OBD provides various data query codes. The data transmitting device 120 can respond to the driving data reading request and send it to the connected OBD. The corresponding query code obtains the returned data and sends it to the bound user terminal 130 .

An optional execution process of step S406 is: obtain the model of the vehicle, and determine the parameters of the vehicle according to the model (the parameters of the vehicle may include any one or more of the following: body size, power parameters, transmission parameters, control configuration parameters , safety configuration parameters), and calculate the driving posture required for the vehicle to turn and drive according to the parameters of the vehicle. Since the vehicle parameters of different models are different, a model database can be established in advance to match and save the model of the vehicle and the corresponding parameters. During the initialization process, the vehicle model database can be accessed in advance to obtain the corresponding vehicle parameters, which can be used as the calculation basis for the driving posture.

An optional execution process of step S408 is: calculating the speed and steering angle required to complete the turn with the driving posture; comparing the vehicle driving data with the difference between the speed and steering angle required to complete the turn; generating driving suggestions according to the comparison results, driving Suggestions include any one or more of the following: change of speed, change of gear, change of turn signal status, direction of turn, angle of turn.

For example, a report such as "successful turning, vehicle speed 20 kilometers per hour, steering angle 60 degrees" is output. At the same time, the vehicle driving data during the turning process can also be saved as historical data for subsequent analysis. For example, when passing through a similar curve next time, it is provided as suggestion data.

The ECU processes and calculates the above data to determine the data reflecting the current posture of the vehicle, compares it with the estimated driving posture required for turning, gives driving suggestions, and records the above data during the turning process as follow-up data basis of analysis.

The above-mentioned predictive calculation of the driving posture required for the vehicle to turn can be selected in any of the following ways: For example, a statistical prediction method (matching the current driving situation with historical data, obtaining the previous similar turning data as the estimated data ); Genetic Algorithms and Neural Network Algorithms (training the previous data to obtain a pre-estimation model, and using the model for pre-estimation); projection pursuit method (projecting high-dimensional data onto a low-dimensional subspace to find reflect the characteristics of the original high-dimensional data). In addition, parameters such as road conditions and driver's driving habits can also be introduced to estimate the driving posture required for the vehicle to turn, and the above algorithm can be corrected and supplemented.

Furthermore, in the process of generating the driving suggestion, the acceleration, braking, and steering performance of the vehicle 110 may also be fully considered, so as to ensure that the driving suggestion can meet the actual situation of the vehicle 110 .
