The invention relates to a double-electric-drive-axle tractor anti-skid control method and system, a driving system and a tractor. The control method comprises the steps that a first parameter and a second parameter are obtained; the first parameters comprise a front axle wheel speed, a middle axle wheel speed, a rear axle wheel speed and a vehicle speed; the second parameters comprise an accelerator pedal state, a brake pedal state, an energy recovery gear state and a gear state; according to the front axle wheel speed, the middle axle wheel speed and the rear axle wheel speed, the slip rate of middle axle wheels and the slip rate of rear axle wheels are determined; determining the slipping state of the vehicle according to the front axle wheel speed, the rear axle wheel speed and the vehicle speed; determining a vehicle driving state according to the second parameter; determining a torque control strategy according to the driving state of the vehicle; and according to the torque control strategy, the torque of the middle axle motor and the torque of the rear axle motor are adjusted till the slip rate of middle axle wheels and the slip rate of rear axle wheels are smaller than or equal to a preset first threshold value.
本发明涉及一种双电驱桥牵引车防滑控制方法、系统、驱动系统及牵引车,控制方法包括:获取第一参数和第二参数;第一参数包括前桥车轮速度、中桥车轮速度、后桥车轮速度和车速;第二参数包括加速踏板状态、制动踏板状态、能量回收挡位状态和挡位状态;依据前桥车轮速度、中桥车轮速度和后桥车轮速度确定中桥车轮的滑移率和后桥车轮的滑移率;依据前桥车轮速度、后桥车轮速度和车速确定车辆的打滑状态;依据第二参数确定车辆行驶状态;车辆的打滑状态为打滑状态,依据车辆行驶状态确定扭矩控制策略;依据扭矩控制策略对中桥电机和后桥电机进行扭矩进行调整,直至中桥车轮的滑移率和后桥车轮的滑移率小于等于预设的第一阈值。
