Plotting-type independent module dynamic trajectory reversing aid system and method thereof

Abstract

The invention discloses a plotting-type independent module dynamic trajectory reversing aid system and a method thereof. The system comprises a rear view camera, a data processing unit, a control unit, an operating system unit, a display screen, an angle information acquisition unit and a timing trigger unit, wherein the angle information acquisition unit is used for acquiring the angle information when a steering wheel rotates; the timing trigger unit is used for providing timing trigger signals to the data processing unit; the data processing unit is used for mapping ground reversing coordinates of an actual vehicle to be reversing trajectory coordinates on the display screen in combination with the steering wheel angle information; and the operating system unit is used for being connected with multiple groups of screen trajectory coordinates to form a real-time dynamic reversing trajectory line. Compared with the traditional method of reading the pre-stored trajectory image, more realistic and more reliable reversing aid information can be provided for a driver; and in addition, the independent data processing unit is adopted, the control unit is freed, and the control performance and the operating speed are improved.

Description

technical field [0001] The invention relates to the field of reversing assistance products, in particular to a dot-drawing independent module dynamic trajectory reversing assistance system and a method thereof. Background technique [0002] In today's society, the number of citizens' cars is increasing, and the safety accidents caused by reversing are also showing an increasing trend. The safety of reversing has also attracted more and more attention from the society. The reversing assistance system can intuitively feed back the situation behind the car to the driver with visual image effects, and at the same time dynamically display the reversing trajectory in real time to assist the driver in reversing safely. But generally all have following defect in existing reversing auxiliary system technology: [0003] 1. Static trajectory is generally used. In the system’s FLASH memory, store the reversing trajectory line picture in the form of a static picture in advance. By calli...

Problems solved by technology

[0005] The object of the present invention is to provide a point-drawing type independent module dynamic trajectory reversing auxiliary system and its method. The method calculates the reversing trajectory through an independent data processing module separated from the controller, so as to liberate the control unit and improve control At the same time, the method of the present invention also calculates the reversing trajectory line in real time according to the obtained steering wheel angle information, solving the problem that the reversing assistance system in the prior art cannot remind the driver to adjust the correction amount according to the actual reversing situation
