Vehicle backing track assistant method

Abstract

The invention relates to a vehicle reverse track auxiliary method, for providing reverse track to driver, used in reverse drive. The invention uses image technique to calculate a steering signal of steering wheel via a track database or math equation, and displays the calculated result on a display, uses the distance with obstacle obtained by an ultrasonic ranging radar as a reference of internal image process, to provide a vehicle reverse track auxiliary method with instant quick reaction, high adaptability and simple installment, to reduce cost.

Description

technical field [0001] The present invention relates to a track assisting method in the technical field of vehicles, in particular to a vehicle reverse track assisting method for assisting a vehicle in reverse by means of image processing. Background technique [0002] When the early vehicles were reversed, parked or slewed, most of them had to be reversed by experience, visual inspection or the assistance of others, which caused a lot of inconvenience in the use of the vehicle. Therefore, the existing vehicles would be installed on the rear bumper of the vehicle body. Set a reversing radar, which mainly uses the principle of ultrasonic radar sensor to send and receive signals to sense the interval time of reflected waves and the distance of obstacles; [0003] However, although the existing vehicle reversing radar is generally equipped with a buzzer to remind the driver and the surrounding people to pay attention, so as to avoid accidentally bumping into objects or people a...

Problems solved by technology

[0003] However, although the existing vehicle reversing radar is generally equipped with a buzzer to remind the driver and the surrounding people to pay attention, so as to avoid accidentally bumping into objects or people at the rear of the car when reversing, it still needs to be detected by the rearview mirror and It is very inconvenient for novices to park the vehicle at the desired location only with experience. In addition, although some operators install cameras on the rear bumper to watch the images behind the vehicle to assist the driver in parking or turning, However, the prediction of vehicle trajectory still needs to be accumulated through long-term experience.

[0004] This shows that the above-mentioned existing vehicle reversing assisting method obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the problems existing in the vehicle reversing assist method, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.
