The invention discloses a wheeled tractor four-wheel drive control system and a control method thereof, the system comprises a service braking signal acquisition device, a vehicle speed signal acquisition device, a four-wheel drive switch, a signal processing device, a pressure control device and a four-wheel drive execution device, the service braking signal acquisition device is used for acquiring service braking signals; the vehicle speed signal acquisition device is used for acquiring the running speed of the wheeled tractor; the four-wheel drive switch is used for sending out an electric signal when being manually turned on; the four-wheel-drive execution device comprises a wet transfer case for four-wheel-drive switching; the pressure control device is used for controlling on-off of hydraulic oil entering the four-wheel-drive execution device. And the signal processing device is used for collecting each signal and sending out a control instruction. The control priority of the signal processing device is higher than that of four-wheel-drive switch control, and two-wheel-drive/four-wheel-drive intelligent switching of the tractor under some conditions is achieved by judging a vehicle speed signal and a service braking signal.

    一种轮式拖拉机四驱控制系统及其控制方法,系统包括行车制动信号采集装置、车速信号采集装置、四驱开关、信号处理装置、压力控制装置和四驱执行装置,行车制动信号采集装置用于采集行车制动信号;车速信号采集装置用于获取轮式拖拉机行驶速度;四驱开关用于在手动打开时发出电信号;四驱执行装置包括进行四驱切换的湿式分动箱;压力控制装置用于控制进入四驱执行装置液压油的通断;信号处理装置作为各信号的收集与控制指令的发出。本发明的信号处理装置控制优先级高于四驱开关控制,通过对车速信号、行车制动信号的判断实现部分条件下拖拉机两驱/四驱的智能切换。
