Automobile safety speed control system and method

Abstract

The invention discloses an automobile safety speed control system, which is mainly composed of a fog image detection unit, a friction system calculation unit, a weather state feedback unit, a vehicle speed detection unit and a control center to ensure safe driving in bad weather, and also includes a radar ranging unit , to further ensure the driving in the case of obstacles. The invention also discloses a method for realizing the control, which includes the following steps: respectively input the signals of the four units into the control center, and when one or more of them are triggered, enter the safe vehicle speed mode; if the trigger condition is not detected, the radar detection unit starts to work and enters the radar mode; the radar does not give an obstacle signal, the vehicle travels at a normal speed and enters the normal driving mode. The present invention sets the safe speed mode as the highest priority to ensure safe driving under severe weather conditions, and further ensures safe driving through radar detection. Three driving modes are automatically switched, thereby realizing safe speed control in various situations.

Description

technical field [0001] The invention relates to vehicle speed control, in particular to a vehicle safety driving speed control system and a control method thereof. Background technique [0002] It is not uncommon for severe weather to cause vehicle accidents, either because the strong wind blows off the driving path of the vehicle, or because the road surface is slippery, causing the vehicle to lose control, or because the road surface is icy, the friction force of the vehicle is small and uncontrollable, driving in foggy days , because the visual distance is shorter and the speed of the vehicle is faster, resulting in traffic accidents such as rear-end collisions. [0003] At present, when such problems occur, most drivers are reminded to drive carefully, but there are many external factors. The common problem is that the speed of the vehicle is too fast or too slow, causing rear-end collision or being rear-ended. How to control the speed of the vehicle is the solution to b...
