The invention provides a method and device for improving the comfort level of self-adaptive cruise, and the method comprises the steps: starting a self-adaptive cruise mode, setting a target vehicle speed, and dividing the self-adaptive cruise mode into a constant-speed cruise mode and a vehicle following mode according to the condition of a front vehicle on a current road; respectively calculating expected accelerations in a constant-speed cruise mode and a car following mode by using a self-adaptive cruise algorithm; and a comfort level function is added, and the expected acceleration algorithms of the constant speed cruise mode and the car following mode are optimized through the comfort level function, so that the comfort level in the self-adaptive cruise mode is improved. According to the method, the comfort function is added in the self-adaptive cruise algorithm of the vehicle to optimize the change of the acceleration of the vehicle, so that the vehicle is relatively gentle in the whole speed change process, and strong pause feeling is not generated, so that the comfort of the vehicle in the self-adaptive cruise mode is improved; the whole system has the advantages of good safety, high reliability, convenient application process and the like.
本发明提供一种提高自适应巡航舒适度的方法和装置,其中,方法包括:开启自适应巡航模式并设定目标车速,依据当前道路上的前方车辆情况,自适应巡航模式分为定速巡航模式和跟车模式;利用自适应巡航算法,分别计算出定速巡航模式和跟车模式的期望加速度;加入舒适度函数,通过舒适度函数分别对定速巡航模式和跟车模式的期望加速度算法进行优化,使得自适应巡航模式下的舒适度得到提高。本发明通过在车辆的自适应巡航算法中增加舒适度函数来优化车辆加速度的变化,使得车辆在整个速度变化过程中比较平缓,不会产生强烈的顿挫感,从而提高车辆在自适应巡航模式下的舒适度,整体具有安全性好、可靠性高、应用过程方便等优点。
