The invention relates to a commercial vehicle electrically-driven hill starting auxiliary system and method, and the method comprises the following steps: a, judging whether a vehicle has a starting condition or not when a function is not activated, if the condition is met, entering b, and if not, keeping a; b, judging whether a driver has a starting intention or not, if so, entering c, and if not, keeping a; c, whether the vehicle slides or not is judged, if yes, the step d is executed, and if not, the step a is kept; d, function activation: the vehicle controller adjusts a motor request torque value according to the current rotating speed moment fed back by the motor controller, adjusts the vehicle driving force by adjusting the motor torque to overcome the vehicle ramp resistance, so that the rotating speed of the motor is maintained at about 0, whether the vehicle has the condition of exiting the starting function or not is judged, if the condition is met, the step e is executed, and if the condition is not met, the step d is executed; and e, gradually reducing the motor torque required by the hill starting assisting function, and quitting the starting function when the motor torque is reduced to 0.

    本发明涉及一种商用车电驱动坡道起步辅助系统及方法,包括如下步骤:a:功能未激活,判断车辆是否具备起步条件,如果条件满足则进入b,如果未则保持a;b:判断驾驶员是否有起步意图,如果有起步意图则进入c,如果未则保持a;c:判断车辆是否溜车,如果溜车则进入d,如果未溜车则保持a;d:功能激活,整车控制器根据电机控制器反馈的当前转速时刻调节电机请求扭矩值,通过调节电机扭矩来调节整车驱动力克服整车坡道阻力,使电机转速维持在0左右,判断车辆是否具备退出起步功能条件,如果条件满足则进入e,如果未则返回d;e:逐渐减小坡道辅助起步功能需求的电机扭矩,电机扭矩减小为0时退出起步功能。
