Detecting the state of the car can read the data of the car's driving computer (ECU) through OBD through a dedicated detection device, which is used to analyze the state of the car and further diagnose the faults of the car. Emission monitoring uses a series of engine sensor data (such as oxygen sensor data) output by OBD to analyze the combustion effect of the engine and determine the emission of the car. As more and more attention is paid to the impact of vehicle emissions on the environment, the OBD interface is currently a mandatory configuration for most international vehicles. The traditional application of OBD is for auto repair shops to perform fault detection, and for detection field to detect emission data.

The head-up display sub-module 246 may be configured to generate a head-up display interface containing driving suggestions, and display it to the driver through the reflective area of the front windshield of the vehicle.

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 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 . Fig. 4 is a schematic diagram of a processing method of vehicle driving data according to an embodiment of the present invention, the processing method of vehicle driving data includes:

The conditions in front of the vehicle that affect the driving of the vehicle include any of the following: obstacles appear in front of the vehicle; vehicles whose speed is significantly lower than the current driving speed appear in front of the vehicle; vehicles change lanes in adjacent lanes. An optional implementation manner is to use multiple cameras arranged on the vehicle 110 to shoot in real time, so as to obtain a panoramic image of the vehicle 110 . The surrounding road conditions can be obtained through image recognition technology, and the key point is to determine whether there is any situation in front of the vehicle that affects the driving of the vehicle.

The parameters of the vehicle include any one or more of the following: body size, power parameters, transmission parameters, control configuration parameters, Safety configuration parameters; calculate the driving posture required for the vehicle to change lanes 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: calculate the speed and steering angle required to complete the lane change with the driving attitude; compare the difference between the vehicle driving data and the speed and steering angle required to complete the lane change; generate a driving suggestion according to the comparison result , the driving suggestion includes any one or more of the following: changing the speed, changing the gear position, changing the state of the turn signal, changing the direction of the lane, and turning the angle.

The estimated driving posture completes the lane change driving suggestion and outputs it to the driver of the vehicle. It can accurately provide the driver with lane change suggestions according to the driving state of the vehicle, which greatly improves the safety and success rate of the vehicle lane change. Traffic accidents caused by lane-changing operation mistakes are avoided. Moreover, the vehicle driving data is provided by the data transmitting device connected to the vehicle's On-Board Diagnostic (OBD) interface, and the data directly comes from the driving computer (Electronic Control Unit, referred to as ECU) for engine, gearbox, brake system, etc. The detection of the relevant data of the components fully and accurately reflects the driving status of the vehicle. Using the current driving data of the vehicle and the analysis of the historical driving data of the vehicle, the driving data of the vehicle for a period of time after the prediction is estimated, and the estimated driving data is obtained accurately. The degree is high, and the suggestion is in line with the actual driving situation, which improves the driving experience of the driver.

During the driving process, the vehicle may have multi-dimensional motion postures, such as up and down motion, lateral motion, longitudinal motion, roll motion, pitch motion, and yaw motion. These movements affect the driving comfort, speed, steering angle, etc. of the vehicle. In the method and device for processing vehicle driving data in this embodiment, the states of up and down motion, lateral motion, longitudinal motion, roll motion, pitch motion, and yaw motion can be measured to determine the overall driving posture of the vehicle.

The vehicle driving data can be calculated and processed by the ECU by obtaining the measurement data of various sensors (such as speed sensors, speed sensors, acceleration sensors, gyroscopes, electronic compass, vibration sensors) mounted on the vehicle, and provided to the data by the OBD interface. The transmitting device 120, through the pre-estimation and calculation of the user terminal 130 or the network-side device 140, determines the driving posture required for the vehicle to change lanes, and gives driving suggestions. For example, three gyroscopes can be used to obtain roll angular velocity, yaw angular velocity, and pitch angular velocity respectively; two biaxial accelerometers can be used to obtain three accelerations: longitudinal acceleration, lateral acceleration, and vertical acceleration; and the electronic compass can be used to measure the vehicle The heading angle of travel. 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 lane change, gives driving suggestions, and records the above data during the lane change, as basis for subsequent data analysis.

The above-mentioned predictive calculation of the driving attitude required for the vehicle to change lanes can be selected in any of the following ways: For example, a statistical prediction method (matching the current driving situation with historical data, obtaining previous similar data when changing lanes as a forecast) estimated data); genetic algorithm and neural network algorithm (train the previous data to obtain the estimated calculation model, and use the model to perform estimated calculation); projection pursuit method (project high-dimensional data onto low-dimensional subspace, To find out the characteristics reflecting the original high-dimensional data). In addition, to estimate the driving posture required for the vehicle to change lanes, parameters such as road conditions and driving habits of the driver can be introduced to correct and supplement the above algorithm.

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 .
