Problems solved by technology

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.

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...
