The invention discloses a cruise control system and method for a tandem type hybrid power tractor, and the method comprises the steps: obtaining the operation information of the tractor through a vehicle control unit, and judging whether the tractor can enter a cruise control state or not; if the operation information meets the preset constant-speed cruise condition, a cruise enable switch is activated to enter a constant-speed cruise state, and the current vehicle speed serves as the cruise speed; when the vehicle is in the cruise control state, the vehicle control unit receives an operation trigger signal from a driver operation system to adjust the cruise speed, reset the cruise speed and quit the cruise control state; power reversing is started in the constant-speed cruise state, the tractor is still kept in the constant-speed cruise activation state, and the tractor continues to conduct constant-speed cruise in the opposite direction after power reversing. The operation efficiency of the tractor is improved through constant-speed cruise, the driving intensity of a driver is relieved, power reversing can be conducted in the constant-speed cruise state, and the tractor can turn around conveniently in the operation process.
本发明公开了一种串联式混合动力拖拉机的定速巡航控制系统和方法,该方法包括:整车控制器获取拖拉机运行信息,判断能否进入定速巡航状态;若所述运行信息满足预设的定速巡航条件,则激活巡航使能开关进入定速巡航状态,以当前的车速为巡航速度;处于定速巡航状态时,整车控制器接收来自驾驶员操作系统的操作触发信号,进行巡航速度的调整、巡航速度的复位以及定速巡航状态的退出;在定速巡航状态下启动动力换向,拖拉机仍保持定速巡航激活状态,使拖拉机在动力换向后以相反的方向继续进行定速巡航。本申请通过定速巡航提高拖拉机作业效率,减轻驾驶员的驾驶强度,且在定速巡航状态下能够进行动力换向,便于拖拉机在作业过程中调头。
