Problems solved by technology
[0003] The purpose of the present invention is to provide a method and system for predicting the dynamic trajectory of the exterior rearview mirror, which is used to solve the problem that the exterior rearview mirror of the passenger car does not have a trajectory line display when the vehicle is turning or reversing to assist the driver in driving, resulting in the scratching of the exterior rearview mirror of the passenger car
[0004] In order to realize the assisted driving of the passenger car and solve the problem that the external rearview mirror of the passenger car does not have a trajectory line display to assist the driver to drive when the vehicle is turning or reversing the problem that the external rearview mirror of the passenger car is scratched, the present invention provides a dynamic trajectory prediction method for the external rearview mirror , including the following steps:

Embodiment Construction
[0019]The present invention will be described in further detail below with reference to the accompanying drawings.
[0020]The present invention provides an outer rearview mirror dynamic trajectory prediction device including an information acquisition module and a controller, such asfigure 1 As shown, the information acquisition module is used to acquire the vehicle gear information and the vehicle speed information, preferably the information acquisition module is a vehicle controller; the information acquisition module includes a steering angle sensor, the vehicle steering angle is acquired by the steering angle sensor, but the steering The angle information can be acquired directly by the controller, or it can be obtained by re-transferring to the controller by the vehicle controller; in addition, the system further includes a display device, an output of the controller, preferably the display The device is a display screen that is disposed at the vehicle central control; and the v...

The invention relates to the technical field of passenger car assisted driving, in particular to a method and system for predicting the dynamic trajectory of an exterior rearview mirror. The system includes a controller and an information collection module, the controller obtains vehicle gear information, vehicle speed information and the steering angle of the vehicle through the information collection module; when the vehicle is in reverse gear or the vehicle is in forward gear and the vehicle speed is less than the speed setting value, the controller generates the running track of the exterior rearview mirror according to the steering angle of the vehicle, the vehicle body parameters and the position of the exterior rearview mirror relative to the vehicle body, realizes the assisted driving of the bus, and solves the problem that the exterior rearview mirror of the passenger car is in the car when the vehicle turns. Or when reversing, there is no track line display to assist the driver to drive, which leads to the problem of scratching the exterior rearview mirror of the bus.
Description
Technical field[0001]The present invention relates to the field of driving auxiliary driving technology, in particular, a dynamic trajectory prediction method and system for outer rear view mirrors.Background technique[0002]At present, some vehicles on the market have a 360 ° facing system with dynamic track lines, which are used to predict the vehicle's reversing trajectory and the turn of the vehicle, and realize the vehicle reversing and steering assist, due to the existing small cars such as the existing car. The outer rearview mirror is disposed at the position of the vehicle body near the middle, so the vehicle reversing and turning trajectory do not need to consider the running trajectory of the rear view mirror during the generation, and a longer model of the bus, school bus, etc., the outer rearview mirror is in the vehicle The front end and the left and right side are highlighted, the most prominent part of the car, the crime of being scraped is the greatest, most passenge...
