Embodiment Construction

[0044] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] The invention provides a dot-drawing independent module dynamic trajectory reversing auxiliary system, its composition structure is as follows figure 1 As shown, the rear view camera is the CAM2363 special reversing camera for the Volkswagen LaVida series, and is installed directly under the license plate light at the rear of the vehicle body, and is connected to the vehicle bus system of the vehicle body through the CAN interface, so that the display can be set in the system. The image captured by the rear view camera is displayed, so that the driver can monitor the situation behind the vehicle in real time according to his own needs when reversing, ensuring the safety of reversing. The DSP model of TI is selected as TMS320VC5402 for the data processing unit, and the purpose is to select a dedicate...

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...
