Vehicle trajectory simulation system and method

Abstract

Provided are a vehicle trajectory simulation system and method. The method comprises the steps: during a vehicle driving process, carrying out real-time detection of vehicle accelerated speed variations Ax, Ay and Az respectively in X, Y and Z axis directions; when any one numerical value of Ax, Ay and Az is greater than a preset threshold, detecting the vehicle driving speed and vehicle angle variations Gx, Gy and Gz respectively in the three-axis directions, and storing the detected data in a memory of a handheld device; and when the vehicle stops moving, stopping storing the data, and simulating the vehicle driving trajectory and the driving direction according to the stored data. With use of the system and the method, the vehicle driving trajectory can be simulated through the handheld device.

Description

technical field [0001] The invention relates to a vehicle tracking system and method, in particular to a vehicle trajectory simulation system and method. Background technique [0002] A driving recorder is an electronic product that can photograph, record and store the entire driving process. Its basic structure includes a set of camera modules, a set of storage modules, and a set of mechanisms fixed on the vehicle. The method of use is to fix the body of the driving recorder inside the car through a fixed structure, connect the power supply to the car charger, and adjust the camera lens to shoot from the inside of the car to the outside, usually forward shooting, that is, shooting the direction of the vehicle. At present, driving recorders have been widely used to record images of vehicles during travel. If a traffic accident occurs during the period, the recorded images can help determine the responsibility for the accident. [0003] However, regardless of whether it is a...

Problems solved by technology

[0003] However, regardless of whether it is a low-end or a high-end driving recorder, it must be connected to the car and used independently. If there are other electronic products connected to the car, such as music players, satellite navigation systems, etc. , will inevitably lead to complex electronic connection lines in the interior space of the car, and the increase in power consumption of multiple different electronic products at the same time

Although some car R&D manufacturers have developed camera modules built into the car body, such cars are usually expensive and cannot be popularized in the market

Even if some driving recorders are equipped with front and rear lenses to record the front and rear road conditions at the same time, when a side impact accident occurs, it is still a blind spot that the camera lens cannot capture, and cannot record the image of the side impact accident. Dash cams don't work as well
