A lane departure correction system and correction method based on wheel braking

Abstract

The present invention provides a lane departure correction system based on wheel braking, comprising a deviation correction unit, a CAN communication unit and a smart phone unit, the two signal output terminals of the ESP / VSC control module of the deviation correction unit are respectively connected to the left and right The signal input end of the rear wheel brake pressure solenoid valve is connected, and the ESP / VSC control module is connected with the bus control module in the CAN communication unit through the CAN bus interface, and the signal output end of the bus control module passes through the vehicle information processing module and the Bluetooth module A communicates with Bluetooth module B in the smart phone unit, and the bluetooth module B communicates with the smart phone processing module; the signal input of the smart phone processing module is also connected with the signal output of the image collection module, and the signal The output terminals are respectively connected with the signal input terminals of the display module and the alarm module. The invention has low installation cost, simple structure and high warning accuracy rate.

Description

technical field [0001] The invention belongs to the field of automobile safety assisted driving, and in particular relates to a lane departure correction system and a correction method based on wheel braking. Background technique [0002] In recent years, due to excessive fatigue and negligence of drivers on expressways, the proportion of major traffic accidents caused by vehicles deviating from the lane has increased year by year. According to the statistics of the "Statistical Bulletin on National Economic and Social Development in 2014", the number of traffic accident deaths in 2014 was 34292.34, an increase of 2688.04 from the 31604.3 deaths in 2013, with a growth rate of 8.5%; The rate was 13.46%; compared with 2011, the growth rate was 15.78%. [0003] U.S. road safety agency research shows that: about 50% of automobile traffic accidents are caused by automobiles deviating from the normal driving lane, and lane departure is also regarded as the main cause of vehicle r...

Problems solved by technology

Although these systems have basically realized functions such as lane departure warning, but for most low-end and mid-end models that do not have this configuration, there are disadvantages such as high installation costs, changes to the original car line, and low warning accuracy.
