The invention discloses a vehicle driving control method, which comprises the following steps: when judging that a vehicle starts a lane centering keeping function, acquiring a current state parameter of a steering wheel of the vehicle; judging whether the current state parameter of the steering wheel is greater than a parameter threshold; if yes, determining whether the directions of the auxiliary steering torque and the external force torque currently provided by the lane centering keeping system of the vehicle are the same or not; if the directions are the same, keeping the steering torque of the lane centering keeping function not changed; if the directions are opposite, gradually reducing the auxiliary steering torque according to the preset reduction amplitude; and when the parameter is not greater than the parameter threshold value, controlling the vehicle to keep lane centering according to the auxiliary steering torque provided by the lane centering keeping function. The invention can solve the problem that in the prior art, if a driver needs to change a lane or avoid an obstacle, the relation between the torque direction sent by the transverse auxiliary system and the torque direction of the driver to the steering wheel is uncertain, and the control force of the driver to the steering wheel is unstable.

    本发明公开了一种车辆驾驶控制方法,包括:当判断到所述车辆开启车道居中保持功能时,获取所述车辆的方向盘的当前状态参数;判断方向盘的当前状态参数是否大于参数阈值;当大于参数阈值时,判断车辆的车道居中保持系统当前提供的辅助转向扭矩和外力扭矩的方向是否相同;若方向相同,则保持车道居中保持功能的转向扭矩不变;若方向相反时,则按预设的减小幅度逐渐减小辅助转向扭矩;当不大于参数阈值时,则按车道居中保持功能提供的辅助转向扭矩控制车辆保持车道居中。本发明能够解决现有技术中如果驾驶员需要变道或避让障碍物时,横向辅助系统发出的扭矩方向与驾驶员对方向盘的扭矩方向关系不确定,使得驾驶员对方向盘的控制力不稳定的问题。
