The invention discloses a vehicle adaptive cruise curve speed control method and device, and the method comprises the steps: detecting whether a current vehicle enters a curve working condition or not; when it is detected that the current vehicle enters the curve working condition, the actual curve curvature of the current curve is calculated, and meanwhile lane line information of the current curve is recognized; the lane where the current vehicle is located is recognized according to the lane line information, a predicted track of the current vehicle is obtained according to the lane where the current vehicle is located and the actual curve curvature, and when the self-adaptive cruise target vehicle is in the predicted track, preset vehicle following cruise actions are executed along with the current vehicle speed of the self-adaptive cruise target vehicle. And otherwise, executing a preset speed-setting cruise action according to the preset self-adaptive cruise speed of the current vehicle. Therefore, the technical problems of low reliability and poor physical examination of self-adaptive cruise and reduced safety of the vehicle caused by the fact that the vehicle is easy to lose or mistakenly follows the target vehicle when the vehicle runs on the curve in the related technology are solved.
本申请公开了一种车辆自适应巡航弯道车速控制的方法及装置,其中,方法包括:检测当前车辆是否进入弯道工况;在检测到当前车辆进入弯道工况时,计算当前所处弯道的实际弯道曲率的同时,识别当前所处弯道的车道线信息;根据车道线信息识别当前车辆的所处车道,并根据所处车道和实际弯道曲率得到当前车辆的预测轨迹,且在自适应巡航目标车辆在预测轨迹内时,跟随自适应巡航目标车辆的当前车速执行预设跟车巡航动作,否则根据当前车辆的预设自适应巡航车速执行预设定速巡航动作。由此,解决了相关技术中在弯道行驶时,容易丢失或者跟错目标车辆,导致自适应巡航的可靠性较低、体检较差,降低了车辆的安全性的技术问题。
