A method of controlling uphill driving of a hybrid vehicle provided with a dual clutch transmission (DCT) may include determining, by a controller, a driving state of a vehicle on the basis of information collected from the vehicle; when the vehicle is determined as being in a uphill driving state, performing, by the controller, high torque control on an engine of the vehicle by increasing an engine torque to control the engine at a predetermined high torque engine operating point and reducing a motor torque of a motor in the vehicle to satisfy a driver request torque; and during the performing of the high torque control on the engine, comparing, by the controller, a state of charge (SOC) value of a battery with a set first SOC threshold value, and when the SOC value of the battery is less than or equal to the first SOC threshold value, performing engine and motor speed control to defend the SOC value of the battery.

    本发明涉及一种控制车辆的上坡行驶的方法。一种控制设置有双离合器变速器(DCT)的混合动力车辆的上坡行驶的方法可以包括:由控制器根据从车辆收集到的信息确定车辆的行驶状态;当车辆被确定为处于上坡行驶状态时,通过增大发动机扭矩以在预定的高扭矩发动机工作点控制发动机并且减小车辆中的电机的电机扭矩以满足驾驶员需求扭矩,由控制器对车辆的发动机执行高扭矩控制;并且在对发动机执行高扭矩控制过程中,由控制器将电池的电量状态(SOC)值与设定的第一SOC阈值进行比较,并且当电池的SOC值小于或等于第一SOC阈值时,执行发动机和电机速度控制,以保护电池的SOC值。
