The invention relates to the technical field of vehicle control, in particular to an anti-slope-sliding control method and system for an intelligent networked passenger car, and the method comprises the steps: obtaining a vehicle gear, the current rotating speed of a motor, the opening degree of an accelerator, the opening degree of a brake pedal and a hand brake state signal, and confirming the current state of the vehicle; according to positive and negative conditions of a gear signal and a motor rotating speed signal, the opening degree of a brake pedal and a hand brake state signal, it is determined that the vehicle is in a slope sliding state, and the slope sliding prevention function needs to be activated; when the vehicle is in the slope sliding state, the difference value between the current rotating speed and the reference rotating speed of the motor is determined, and the slope sliding torque of the motor is calculated; the rotating speed change rate is calculated according to the rotating speed values of the four continuous time points, and through comparison with the reference rotating speed change rate, the torque proportionality coefficient and the integral coefficient in the period of calculating the sliding slope torque of the motor are dynamically adjusted; and during activation of the anti-slip function, quitting the anti-slip function in a corresponding quitting mode according to the acquired accelerator opening, brake pedal opening and hand brake state signals.

    本发明涉及车辆控制技术领域,具体为一种智能网联客车防溜坡控制方法及系统,获取车辆档位、电机当前转速、油门开度、刹车踏板开度以及手刹状态信号,确认车辆当前状态,根据档位信号、电机转速信号的正负情况、刹车踏板开度以及手刹状态信号,确定车辆处于溜坡状态并需要激活防溜坡功能;车辆处于溜坡状态下,确定电机当前转速与基准转速之间的差值,并计算电机溜坡扭矩;根据四个连续时间点的转速值计算转速变化率,并通过与基准转速变化率之间的对比,对计算电机溜坡扭矩期间的扭矩比例系数和积分系数进行动态调整;防溜坡功能激活期间,根据获取的油门开度、刹车踏板开度以及手刹状态信号,以相应的退出模式退出防溜坡功能。
