A system and method capable of automatically passing a narrow road at low speed

Abstract

The invention discloses a system and method enabling an automobile to automatically pass through a narrow road at a low speed. The system comprises an electronic control unit, a camera, an ultrasonic sensor, a touch display module, an electric power steering system, an electronic stabilizing system, an engine managing system, an electronic gear shifting system and an electronic parking and braking system, wherein the camera, the ultrasonic sensor, the touch display module, the electric power steering system, the electronic stabilizing system, the engine managing system, the electronic gear shifting system and the electronic parking and braking system are connected with the electronic control unit. The method comprises the following steps that after the electronic control unit receives a system activating request, when the automobile meets activating conditions, the electronic control unit plans a driving route according to obstacle information around the automobile, and besides, determines a target gear, a target speed and a target rotating angle of a current driving automobile; and then the electronic control unit interacts with the electric power steering system, the electronic stabilizing system, the engine managing system, the electronic gear shifting system and the electronic parking and braking system to keep the automobile automatically driving according to the planned driving route in the target gear at the target speed and in the target rotating angle. According to the system and the method disclosed by the invention, the automobile can automatically, safely and conveniently pass through the narrow road, so that the occurrence of a colliding accident is avoided.

Description

technical field [0001] The invention belongs to the field of automobile electrical appliances, and in particular relates to a system and method capable of realizing the low-speed automatic passage of an automobile through a narrow road. Background technique [0002] With the improvement of living standards, cars and human life are becoming more and more inseparable. More and more people own private cars. At the same time, facing the increasingly complex traffic environment, more and more drivers hope to The driving process is assisted to ensure driving safety, and the technology of controlling the vehicle to automatically pass through narrow roads can allow car owners to experience safety and convenience when passing through narrow roads, and prevent unnecessary collisions caused by driver's misjudgment. [0003] At present, drivers mainly use the following three methods when driving vehicles through narrow roads: 1. Rely on personal sense of distance and direction; 2. Rely ...

AI Technical Summary

Problems solved by technology

[0003] At present, drivers mainly use the following three methods when driving vehicles through narrow roads: 1. Rely on personal sense of distance and direction; 2. Rely on on-site guidance from personnel outside the vehicle; 3. Use vehicle imaging equipment for assistance; Because drivers need to control steering and braking, and different drivers have different sense of direction, distance and reaction ability, it often causes collision accidents when vehicles pass through narrow roads, which affects driving safety and convenience.
