A parking assistance method, device, system and automobile

Abstract

The invention provides a parking assisting method, device and system and an automobile. The parking assisting method includes the steps that a steering signal of a steering wheel is acquired; corner parameters are generated according to the steering signal, and the turning radius is calculated through the corner parameters; according to the turning radius, rotation angles of multiple preset single light sources are respectively obtained through calculation; each corresponding single light source is controlled to rotate to the corresponding direction according to the rotation angle, and corresponding light indication information is projected onto the ground. Through the scheme, the problems that a traditional backup image and a traditional backup radar only have the prompt function, what is displayed on a screen is a 2D image, the sense of space and distance is weak, and consequentially the parking process is not accurate enough are solved, assistance is provided for a driver to complete the parking work with a projected light signal as the indication, the indication identification is directly displayed in a parking space, and thus the parking process is more visualized and more stereoscopic and shows more sense of space and the parking difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a parking assistance method, device, system and automobile. Background technique [0002] With the improvement of people's living standards, cars have entered more and more households as a means of transportation, and according to statistics, the number of car ownership is still increasing in a considerable number. Parking difficulties are common, especially for new drivers who have just got their driver's license. Although the reversing image and the reversing radar are assisted, the reversing radar is only a reminder, and the reversing image is similar to displaying a 2D image on the screen, so the sense of space and distance is not strong. Contents of the invention [0003] In order to overcome the problem that the traditional reversing image and the reversing radar are only reminders, what is displayed on the screen is a 2D image, the sense of space and distance is not...
