The invention relates to the technical field of intelligent driving, and provides a vehicle speed control method for a vehicle rotating hub, a vehicle-mounted industrial personal computer and a vehicle speed control system.The method comprises the steps that a linear quadratic regulator LQR is adopted, and according to the actual vehicle speed and the predicted vehicle speed of the vehicle rotating hub, the predicted acceleration is determined; determining a speed control mode according to the predicted acceleration; under the condition that the speed control mode is an acceleration mode, a proportion-integration-differentiation (PID) controller is adopted to control the vehicle to reach the predicted vehicle speed from the actual vehicle speed; and under the condition that the speed control mode is a braking mode, an advanced emergency braking system (AEBS) is adopted to control the vehicle to reach the predicted vehicle speed from the actual vehicle speed. According to the method, through coordination and cooperation among the LQR, the PID controller and the AEBS, the test cost is reduced, meanwhile, different devices can be adopted for different predicted accelerations, vehicle speed control can be flexibly and effectively achieved, and the accuracy of vehicle speed control is improved.

    本发明涉及智能驾驶技术领域,提供一种车辆转毂的车速控制方法、车载工控机及车速控制系统,该方法包括:采用线性二次型调节器LQR,根据车辆转毂的实际车速和预测车速,确定预测加速度;根据预测加速度,确定速度控制模式;在速度控制模式为加速模式的情况下,采用比例‑积分‑微分PID控制器,控制车辆从实际车速达到预测车速;在速度控制模式为制动模式的情况下,采用先进紧急制动系统AEBS,控制车辆从实际车速达到预测车速。该方法通过LQR、PID控制器和AEBS之间的协调配合,在降低了试验成本的同时,针对不同的预测加速度,能够采用不同的装置,灵活且有效地实现车速控制,以提高车速控制的准确性。
