Technical Field

The present invention relates to a monitoring and tracking system and method, and more particularly, to a monitoring and tracking system and method for a vehicle.

Background

As is well known, when an automobile runs on a bumpy road surface, the trunk cover of the automobile can move relatively to the side wall, and when the relative displacement exceeds a certain degree, the trunk cover can rub against the side wall, so that paint damage and metal plate corrosion can be caused. Therefore, before the vehicle leaves the factory, the relative movement of the trunk lid and the side wall of the vehicle is often tested through tests, and the risk caused by collision between the trunk lid and the side wall of the vehicle is evaluated.

At present, two methods are adopted in the existing test: firstly, locally arranging plasticine, and observing whether the plasticine breaks down to judge whether the eraser can be rubbed; secondly, arranging a displacement or acceleration sensor to collect data, and performing further data processing at the later stage. The former method is simple and convenient, but has poor precision and is difficult to distinguish the test result; the latter method has high precision, but has long preparation time, high equipment cost, non-intuitive acquired data and complex data processing method.

In addition, the two conventional test methods are only suitable for single dynamic driving tests with short total time and less total mileage, and are not suitable for durable sports cars with large time span and long mileage, which have the total mileage of 10000-100000 km and take 2-6 months.

Therefore, the invention is expected to obtain a system for monitoring and tracking the collision and friction of the trunk lid and the side wall of the vehicle in the driving process by optimally designing a detection and tracking means, and can clearly know the frequency of collision and friction and the corresponding road condition by combining collision monitoring data and GPS position data through later-stage data processing, thereby providing powerful support for risk assessment and further analysis.

The system for monitoring and tracking the collision between the trunk lid and the side wall of the vehicle is simple in structure and suitable for being arranged on a durable sports car for long-term tracking. In fact, after arranging for the first time and accomplishing, only need regularly change the metal paster (because there is the corrosion, the time of a specified duration can influence and listen the precision), can satisfy the experimental demand of durable sports car, carry out long-term stable tracking to it.
