The embodiment of the invention provides a hill assisted start control method, a hill assisted start control system and a vehicle, and relates to the technical field of vehicle control systems. The hill assisted start control method comprises the following steps: establishing an anti-slip torque value prediction mechanism; calculating an anti-slip torque prediction value according to the anti-sliptorque value prediction mechanism; acquiring whole vehicle driving state information; controlling a driving motor system to enter a hill assisted start mode according to the driving state information; and outputting an anti-slip torque target value according to the anti-slip torque prediction value, and entering a torque control system for maintaining the zero rotating speed. The hill assisted start control method can determine the hill anti-slip torque value required for the vehicle to be static on the hill, prevents backward slip of the vehicle, and is helpful for achieving hill-start of the vehicle.

    本发明的实施例提供了一种坡道辅助起步控制方法、坡道辅助起步控制系统和车辆,涉及车辆控制系统技术领域。该坡道辅助起步控制方法包括建立防溜坡扭矩值预测机制;根据防溜坡扭矩值预测机制,计算防溜坡扭矩预测值;获取整车行驶状态信息;根据行驶状态信息,控制驱动电机系统进入坡道辅助起步模式;根据防溜坡扭矩预测值,输出防溜坡扭矩目标值,并进入维持零转速的扭矩控制系统。该坡道辅助起步控制方法能够确定车辆在坡道上静止所需的防溜坡扭矩值,防止车辆后溜,有助于实现车辆的坡道起步。
