The present invention relates to the eco-cruise: fuel-economy optimized cruise control. A method includes receiving a set speed, a maximum allowed speed and a minimum allowed speed, wherein the maximum allowed speed and the minimum allowed speed define an allowed speed range; commanding a propulsion system to produce a commanded axle torque to maintain the set speed; monitoring the current vehiclespeed of the vehicle; determining whether the current vehicle speed is between a first speed value and a second speed value, wherein the first speed value is the sum of the minimum allowed speed anda first predetermined value, and the second speed value is the difference obtained by subtracting a second predetermined value from the maximum allowed speed; and in response to determining that the current vehicle speed is not between the first speed value and the second speed value, commanding the propulsion system to adjust the commanded axle torque in order to maintain the current vehicle speed within the allowed speed range.

    本申请涉及生态巡航:燃料‑经济性优化的巡航控制。方法包括接收设定速度、最大允许速度和最小允许速度,其中最大允许速度和最小允许速度限定允许速度范围;命令推进系统产生命令轴扭矩以维持设定速度;监视交通工具的当前交通工具速度;确定当前交通工具速度是否在第一速度值和第二速度值之间,其中第一速度值是最小允许速度加上第一预定值,而第二速度值是最大允许速度减去第二预定值;并且响应于确定当前交通工具速度不在第一速度值和第二速度值之间,命令推进系统调节命令轴扭矩以维持当前交通工具速度在允许速度发范围内。
