The invention relates to an intelligent driving vehicle and a hill starting control method thereof, and belongs to the technical field of intelligent vehicle control. In order to guarantee that the vehicle can be static on the ramp, different accelerator signal values are correspondingly output to serve as basic accelerators according to different gradients and ramp surfaces, meanwhile, a superposition accelerator is determined according to backward friction force of vehicle tires along the ramp surfaces, and the basic accelerators and the superposition accelerator are superposed to counteract reverse force caused by vehicle slope sliding due to the ramp. In addition, in order to guarantee that the vehicle runs according to the target vehicle speed, proportional control is conducted on an accelerator according to the difference value between the current vehicle speed and the preset vehicle speed in the vehicle running process, so that it is guaranteed that the vehicle is stably accelerated to the target vehicle speed; according to the method, auxiliary equipment does not need to be additionally arranged, human intervention is not needed, the vehicle is directly and successfully started, and the problem that the vehicle needs different driving forces on different ramps is solved with low cost.

    本发明涉及一种智能驾驶车辆及其坡道起步的控制方法,属于智能车控制技术领域;为保证车辆能够静止在坡道上,根据坡度和坡道面的不同,对应输出不同的油门信号值作为基础油门,同时,根据车辆轮胎沿坡道面向后的摩擦力确定叠加油门,将基础油门和叠加油门进行叠加以抵消因坡道导致车辆溜坡的反向力;除此之外,为了保证车辆按照目标车速行驶,根据车辆行驶过程中的当前车速和预设车速之间的差值对油门进行比例控制,以保证车辆平稳加速到目标车速;本发明不需要额外增加辅助设备,也不需要人为干预,直接使得车辆成功起步,低成本地解决了车辆在不同坡道所需要不同的驱动力的问题。
