The invention relates to the field of vehicle safe driving, in particular to a lane keeping auxiliary optimization method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining a first distance and a second distance from the center of a current vehicle to lane lines at two sides of a current lane, calculating a current center line offset distance value of the current vehicle according to the first distance and the second distance, and calculating a transverse deviation speed of the current vehicle according to the current center line offset distance value, a historical center line offset distance value and change time between the current center line offset distance value and the historical center line offset distance value, and according to the transverse deviation speed and the preset distance between the wheels and the lane lines on the two sides, the deviation correction time of the current vehicle is calculated, and deviation correction control is conducted on the current vehicle according to the deviation correction time, so that the current vehicle is kept in the target interval of the current lane. Therefore, the problems that the system is too abrupt and disturbs driving when intervening in deviation rectification are solved, the lane is optimized, the auxiliary experience feeling is kept, and the use frequency of the auxiliary function by the user is increased.

    本发明涉及车辆安全驾驶领域,具体涉及一种车道保持辅助优化方法、装置、车辆及存储介质,其中,方法包括:获取当前车辆的中心至当前所处车道两侧车道线的第一距离和第二距离,根据第一距离和第二距离计算当前车辆的当前中心线偏距值,并根据当前中心线偏距值、历史中心线偏距值和当前中心线偏距值与历史中心线偏距值之间的变化时间计算当前车辆的横向偏离速度,根据横向偏离速度和预设的车轮至两侧车道线距离计算当前车辆的纠偏时间,并根据纠偏时间对当前车辆进行纠偏控制,使得当前车辆保持在当前所处车道的目标区间内。由此,解决了系统介入纠偏时过于突兀,干扰驾驶等问题,优化车道保持辅助的体验感,增加用户对辅助功能的使用频率。
