Problems solved by technology

However, whether it is infrared technology or visual recognition technology, the common problem is that it greatly increases the power consumption of the non-power system of the car, and the setting of the early warning threshold is too simple, which is prone to false triggering
We are very familiar with technologies such as Zigbee. The disadvantage of similar technologies is that they must be powered by additional batteries.

Abstract

The invention relates to a vehicle-mounted lane departure collision early warning system. The vehicle-mounted lane departure collision early warning system comprises various apparatuses embedded in a vehicle body, i.e. a capacitance-type approaching sensing distance sensing module at the side surface of the vehicle body, ultrasonic distance sensing modules at the front and the rear of the vehicle body, a wheel angle sensor module, a wheel rotation speed sensor module, a terminal control module, and a signal extraction algorithm solidified at the capacitance-type approaching sensing distance sensing module. By monitoring a distance between a vehicle and an obstacle surrounding the vehicle in real time, using a low-power-consumption short-distance wireless communication technique and a flexible and effective filter algorithm, a lane departure and collision early warning can be issued to a driver in time, so that the control experience of a user to a car is greatly improved, the driving stability of the car under different environmental conditions is higher, and the safety and comfort when a car is used are improved.

Description

technical field [0001] The invention relates to the field of automobile auxiliary driving, in particular to a vehicle-mounted road departure collision warning system. Background technique [0002] The lane departure warning system is a system that assists the driver to reduce traffic accidents caused by lane departure by means of an alarm. The lane departure warning system consists of image processing chips, controllers, sensors, etc. According to statistics from the Ministry of Communications, about 50% of automobile traffic accidents are caused by automobiles deviating from the normal driving lane. 23% of car drivers fell asleep on the steering wheel at least once a month; 66% of truck drivers themselves dozed off while driving; 28% of truck drivers fell asleep on the steering wheel within a month experience. Such an astonishing proportion is enough to prove the importance of preventing lane departure. [0003] At present, the lane departure warning system is mainly co...
