Embodiment 1

[0025] A system for drawing driving tracks based on vehicle data, comprising: a track drawing module, a bus data monitoring device, an OBD interface and an intranet CAN bus; the bus data monitoring device is connected to the OBD interface of the vehicle and the intranet CAN bus, It monitors the vehicle bus and transmits the data to the drawing track module, which is used to analyze the data and draw the track in real time. The overall structure is as follows: figure 1 shown.

[0026] The OBD interface and the intranet CAN bus provide a large amount of vehicle driving information, including speed, steering angle, yaw rate, yaw rate, steering wheel angle, lateral acceleration, longitudinal acceleration, etc.; the cycle of the intranet CAN bus data is 100ms ;The OBD interface data period is 300ms; the high sampling frequency ensures the accuracy of the trajectory, and the principle of trajectory drawing is as follows: figure 2 shown.

Abstract

The invention provides a system and method for drawing a driving track on the basis of vehicle data. The system comprises a track drawing module, bus data monitoring equipment, an OBD interface and an intranet CAN bus; the bus data monitoring equipment is connected to the OBD interface and the intranet CAN bus of a vehicle and used for monitoring a vehicle bus and transmitting data to the track drawing module, and the track drawing module is used for analyzing the data and drawing the track in real time. According to the method, the method of drawing the driving track according to the driving data of the vehicle itself is adopted, the driving track can be recorded in real time without needing external information, and meanwhile a high-precision inertial navigation module is not needed, so that the measurement cost is reduced.

Description

technical field [0001] The invention relates to a method for drawing a driving track, in particular to a system and a method for drawing a driving track based on vehicle data. Background technique [0002] With the improvement of living standards, more and more people start to use cars, and the requirements for vehicles are gradually increasing; therefore, after the production of cars, car manufacturers usually test the performance and operating conditions of cars, among which , the working condition related to the driving trajectory is one of the more concerned working conditions. At present, the drawing of driving trajectories mostly adopts the method of sensor measurement. Due to the influence of factors such as the accuracy of the sensor itself, the installation error of the sensor, and the temperature drift, the trajectory drawing error of this scheme is relatively large and the cost is high. Contents of the invention [0003] In view of the above shortcomings or def...
