Lane departure correction system and correction method based on electric power steering

Abstract

The invention provides a lane departure correction system based on electric power steering. The system comprises a departure correction unit, a CAN communication unit and a smart phone unit. Two signal output ends of a CAN bus interface of the departure correction unit are connected with the signal input end of a steering assistance motor and the signal input end of a steering lamp respectively through an auxiliary control module and an automobile light control module, and the CAN bus interface is in communication connection with a bus control module in the CAN communication unit; the signal output end of the bus control module is in communication with a Bluetooth module B in the smart phone unit sequentially 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; and the signal input end of the smart phone processing module is further connected with the signal output end of an image collecting module, and the signal output end is connected with the signal input end of a display module and the signal input end of an alarm module. The system is low in additionally-arranged cost, simple in structure and high in early 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 electric power steering. 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...
