The invention discloses a hybrid power caterpillar tractor driven by a single motor and a control method and a controller of the hybrid power caterpillar tractor. The hybrid power crawler tractor comprises a walking system and a power system, wherein the walking system comprises two walking crawlers located on the opposite sides of a frame respectively, wheel edge brakes connected with the walking crawlers respectively, and a differential mechanism, a reduction gearbox, a driving motor and a driving motor controller which are jointly and sequentially connected with the two wheel edge brakes; the power system comprises a power battery, and an engine and a generator which are directly connected; and the control system comprises a generator controller and a vehicle control unit, and the vehicle control unit is configured to perform coordinated control on charging and discharging of the power battery and power output of the engine. The hybrid power crawler tractor fills the blank that no hybrid power crawler tractor exists in the current market, compared with an existing crawler tractor, the whole vehicle cost, fuel consumption and carbon emission are greatly reduced, and the hybrid power crawler tractor is more suitable for farming areas and conforms to the development direction of green and energy-saving agricultural machinery.

    本申请公开了一种单电机驱动的混合动力履带拖拉机及其控制方法和控制器。该混合动力履带拖拉机包括:行走系统,包括分别位于车架相对侧的两个行走履带、每一行走履带各自连接的轮边制动器以及两个轮边制动器共同依次连接的差速器、减速箱、驱动电机和驱动电机控制器;动力系统,包括动力电池以及相直连的发动机和发电机;以及控制系统,包括发电机控制器和整车控制器,且整车控制器被配置为对动力电池的充放电和发动机的动力输出进行协调控制。本申请填补了当前市面上没有混合动力履带拖拉机的空白,相比于现有履带式拖拉机,极大地减少了整车成本、燃油消耗和碳排放,更适于农耕地区,符合绿色节能农机的发展方向。
