Abstract

The invention discloses a lane boundary-oriented emergency steering auxiliary method and device. The method comprises the following steps of planning a target driving track of a current vehicle in a lane, determining traveling parameters according to the target traveling track and the current position, splitting the target driving track according to the acceleration change rate to obtain N sections of segmented driving tracks, and enabling the acceleration change rate of every two adjacent sections of driving tracks to be zero, selecting a section closest to the current position as a current driving path, calculating the distance and angle between the current position and the terminal point of the current driving path, and controlling the current vehicle to advance according to the current driving path, and when the current vehicle arrives at the terminal point of the current driving path, selecting the next segment of the driving track as the current driving path, and repeating the steps until the current vehicle travels to the terminal point of the last segment of the driving track. The target driving track is split according to the acceleration change rate, what can be guaranteed is that the vehicle is more stable in the driving process, and the good feeling degree of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an emergency steering assist method and device facing lane boundaries. Background technique [0002] In recent years, with the rapid development of automotive active safety electronic control technology and related control strategies, the rapid development of automatic driving technology, the emergency steering assist function has been applied to more vehicles, and the emergency steering assist function can remind the driver to pay attention before the vehicle deviates from the lane. , and automatically take safety measures in emergency situations, which can effectively reduce the occurrence of vehicles deviating from the lane. There are currently some emergency steering assist technologies that automatically initiate emergency braking and emergency steering interventions through dynamic intervention in an emergency. In actual situations, the position, direction of trave...
