The invention discloses a self-adaptive cruise control method and device, relates to the technical field of intelligent driving, and is used for solving the problems of comfort reduction and energy consumption increase caused by frequent vehicle acceleration adjustment and large adjustment amplitude when the condition of a road in front of a front vehicle changes in the cruise process. The method comprises the steps of predicting whether a front vehicle accelerates or decelerates according to front road information of the front vehicle; according to the actual distance between the vehicle and the front vehicle, the speed of the vehicle and the speed of the front vehicle, the expected acceleration of the vehicle is determined, and it is determined that the vehicle is accelerated or decelerated; when the front vehicle and the vehicle are both accelerated or both decelerated, the acceleration is adjusted in a large range, and when the front vehicle and the vehicle are predicted to be accelerated or decelerated oppositely, the acceleration is adjusted in a small range. By setting different acceleration adjusting ranges, the speed change of the vehicle can be slowed down when specific conditions are met, the driving comfort is improved, and energy is saved.
本申请公开了一种自适应巡航控制方法及装置,涉及智能驾驶技术领域,用于解决在巡航过程中前车的前方道路状况发生变化时,车辆加速度调节频繁、调节幅度大造成的舒适度下降及能源消耗量提升的问题。该方法包括:根据前车的前方道路信息预测前车为加速或减速;根据本车与前车的实际车间距、本车车速和前车车速确定本车的期望加速度并确定本车为加速或减速;当预测前车与本车均为加速或均为减速时,使加速度在较大的范围内调节,当预测前车与本车加速或减速情况相反时,使加速度在较小的范围内调节。本申请通过设定不同的加速度调节范围,可以在达到特定条件时减缓本车速度变化,提高驾驶舒适度,节省能源。
