The invention provides a braking method and device of an electric tractor and the electric tractor, and is characterized in that the braking method comprises the following steps: obtaining a braking target of the tractor; whether the braking target is larger than the maximum braking force of an energy recovery braking system of the tractor or not is judged; and if not, according to the driving state parameters of the tractor, the coupling relation between the trailer braking loop and the braking target is established/released. When braking and energy recovery are carried out through the energy recovery braking system, whether a current vehicle can carry out decoupling of a trailer braking loop and a braking target or not can be judged according to the driving state parameters of a tractor, and then the trailer braking loop can be decoupled in some safe driving states; according to the invention, the energy recovery braking system can recover energy more fully, and the connection between the trailer braking loop and the braking target can be kept in some driving states with risks, so that the effect of ensuring the driving safety is achieved.

    本发明提供一种电动牵引车的制动方法、装置及电动牵引车,其特征在于,其包括以下步骤:获取牵引车的刹车制动目标;判断刹车制动目标是否大于牵引车的能量回收制动系统的最大制动力;若不大于,根据牵引车的行驶状态参数,建立/解除挂车制动回路与刹车制动目标的藕合关系。通过能量回收制动系统进行制动与能量回收时,可根据牵引车的行驶状态参数判断当前车辆是否能够进行挂车制动回路与刹车制动目标的解耦,进而在一些安全的行驶状态下,可使挂车制动回路进行解耦,使能量回收制动系统能够更加充分地进行能量回收,在一些具有风险的驾驶状态下,可使挂车制动回路保持与刹车制动目标之间的联系,进而达到保障驾驶安全的效果。
