The invention discloses a vehicle starting control method which comprises the following steps: S1, acquiring an accelerator opening degree, if the accelerator opening degree is greater than an accelerator opening degree threshold value, judging that a vehicle is in a starting state, and entering the step S2; s2, acquiring electronic braking state information, and judging whether the vehicle is in a starting state of electronic braking control or not; if yes, entering the step S3; s3, the current first target torque of the clutch is calculated according to the current vehicle speed and the target vehicle speed, and the current first actual torque, limited according to the current first slope limiting value, of the clutch is determined; a current second target torque is calculated according to the current rotating speed and the target rotating speed of the engine, and a current second actual torque limited according to the current second slope limit value and the current ramp correction coefficient is determined; and S4, the current actual output torque of the clutch is determined according to the maximum torque in the current first actual torque and the current second actual torque. The output torque of the clutch can be loaded in advance, and the impact feeling when the clutch is rapidly combined is optimized.
本发明公开了一种车辆起步控制方法,包括:S1:获取油门开度,若油门开度大于油门开度阈值,判断车辆处于起步状态,并进入步骤S2;S2:获取电子制动状态信息,判断车辆是否处于电子制动控制的起步状态;若是,则进入步骤S3;S3:根据当前车速和目标车速计算离合器的当前第一目标扭矩,并确定根据当前第一斜率限值限制的离合器的当前第一实际扭矩;根据发动机的当前转速和目标转速计算当前第二目标扭矩,并确定根据当前第二斜率限值、当前坡道修正系数限制的当前第二实际扭矩;S4:根据当前第一实际扭矩和当前第二实际扭矩中的最大扭矩确定离合器的当前实际输出扭矩。能够提前加载离合器的输出扭矩,优化离合器快速结合时的冲击感。
