The invention discloses a driving-assisted ramp starting control method which comprises the following steps: S1, after an ADAS (Advanced Data Actuator System) sends a starting request, judging whether a vehicle is in an uphill ramp or not; if yes, entering a starting control process; and S2, the starting control process comprises the steps that hydraulic braking torque is applied to the vehicle through a braking controller ESP, then driving torque is applied, the hydraulic braking torque is gradually reduced till the hydraulic braking torque is zero, and at the moment, the stability of the vehicle before starting movement is kept through the applied driving torque. The method has the advantages that the vehicle is kept static through EPB parking, hydraulic braking and driving torque, it is ensured that the vehicle does not slide backwards, and the safety of the vehicle is greatly improved. EPB starting is switched to hydraulic braking and driving torque tradeoff and tradeoff type starting, noise caused by displacement of a brake disc and a friction plate cannot be generated, and therefore the NVH performance is greatly improved.

    本发明公开了一种辅助驾驶的坡道起步控制方法,包括如下步骤:S1、在ADAS发出起步请求后,判断车辆位置是否处于上坡坡道;若是则进入起步控制流程;S2、起步控制流程包括:先通过制动控制器ESP对车辆施加液压制动力矩,然后施加驱动力矩并逐步减小液压制动力矩直至液压制动力矩为0,此时由施加的驱动力矩保持车辆的起步运动前的稳定。本发明的优点在于:由EPB驻车到液压制动保持车辆静止,再到驱动力矩保持车辆静止,确保了车辆不后溜,极大提升了车辆的安全性。由EPB起步切换到液压制动和驱动力矩此消彼长式的起步,不会产生由于制动盘与摩擦片位移而导致的噪声,因此极大提升了NVH性能。
