A cruise control method for a vehicle includes: receiving a set speed; and determining a commanded axle torque to maintain a set speed on a flat road. The method further includes commanding a propulsion system of the vehicle to generate a commanded axle torque to maintain the set speed; and applying a fading memory filter to the command axle torque to produce a filtered torque command. The method further includes determining an arbitration torque command from the filtered torque command; and commanding a propulsion system of the vehicle to generate the decided torque command. In addition, the method further includes: determining that the gradient of the road is greater than a predetermined gradient threshold; setting a temporary set speed; and commanding a propulsion system of the vehicle to maintain the vehicle at the temporary speed.
本公开涉及一种用于车辆的巡航控制方法,包括:接收设定速度;以及确定命令车轴扭矩,以在平坦道路上保持设定速度。该方法还包括:命令车辆的推进系统产生命令车轴扭矩,以保持设定速度;以及将渐消记忆滤波器应用于命令车轴扭矩,以产生滤波后的扭矩命令。该方法还包括:根据滤波后的扭矩命令确定裁定扭矩命令;以及命令车辆的推进系统产生裁定扭矩命令。此外,该方法还包括:确定道路的坡度大于预定坡度阈值;设定临时设定速度;以及命令车辆的推进系统将车辆保持在临时速度。
