Lane departure correcting system based on wheel brake and correcting method for lane departure correcting system

Abstract

The invention provides a lane departure correcting system based on wheel brake. The lane departure correcting system comprises a departure correcting unit, a CAN (controller area network) communication unit and a smart phone unit, wherein two signal output ends in an ESP / VSC control module of the departure correcting unit are respectively connected with signal input ends of left and right rear wheel brake pressure solenoid valves; the ESP / VSC control module is in communication connection with a bus control module in the CAN communication unit through a CAN bus interface; a signal output end of the bus control module is sequentially in communication connection with a Bluetooth module B in the smart phone unit through a vehicle-mounted information processing module and a Bluetooth module A; the Bluetooth module B is in communication connection with the smart phone processing module; a signal input end of the smart phone processing module is further connected with a signal output end of an image collecting module; and a signal output end of the smart phone processing module is respectively connected with signal input ends of a display module and an alarm module. The lane departure correcting system is low in mounting cost, simple in structure and high in pre-warning accuracy.

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...
