The invention belongs to the technical field of vehicles, and particularly relates to a control method, a control device and a control system for vehicle turning driving. The vehicle turning driving control method comprises the following steps: the current vehicle speed of a vehicle and the curvature radius of a lane are obtained through the curvature radius; the current deceleration time of the vehicle is calculated according to the current vehicle speed and the distance between the vehicle and the lane; according to the fact that the current deceleration time is larger than first preset deceleration time and smaller than second preset deceleration time, an alarm is controlled to be started; and the vehicle is controlled to decelerate according to the condition that the current deceleration time is less than the first preset deceleration time. According to the control method for vehicle turning driving, an alarm gives an alarm in advance to remind a driver according to the turning condition of the front lane, or the vehicle is controlled to decelerate and the vehicle speed is controlled to be decelerated to a certain safety limit value according to the condition that the current deceleration time is shorter than the first preset time, so that the vehicle speed is reduced, and the problem of large driving danger is avoided.
本发明属于车辆技术领域,具体涉及一种车辆过弯行驶的控制方法、控制装置及控制系统。本发明的车辆过弯行驶的控制方法包括如下步骤:曲率半径获取车辆的当前车速和车道的曲率半径;根据当前车速及车辆距离车道的距离计算出车辆的当前减速时间;根据当前减速时间大于第一预设减速时间、且小于第二预设减速时间,控制报警器开启;根据当前减速时间小于第一预设减速时间,控制车辆减速。本发明的车辆过弯行驶的控制方法中,根据前方车道转弯情况,提前通过报警器报警提醒司机,或根据当前减速时间小于第一预设时间,或控制车辆减速,控制车速减速到一定的安全限值下,降低车速,避免造成较大行驶危险问题。
