具有预见性巡航功能的卡车巡航控制系统开发

为了提高卡车在行驶过程中的安全性与舒适性,减轻驾驶员的驾驶疲劳,提出一种具有预见性巡航功能的卡车巡航控制系统.在定速巡航功能的基础上,可根据预见性巡航的激活状态对预见性巡航的挡位和扭矩进行控制,实现预见性巡航的控制目标.采用模糊PID控制算法对卡车的实时车速进行调节,使其与期望的巡航车速保持一致.对所开发的巡航控制系统...

Development of Truck Cruise Control System with Predictive Cruise Function

In order to improve the safety and riding comfort of the truck in the process of driving and reduce the driver's driving fatigue,a truck cruise control system with predictive cruise function is proposed.On the basis of constant speed cruise function,the gear and torque of predictive cruise can be controlled according to the active state of predictive cruise,so as to achieve the control goal of predictive cruise.Fuzzy PID control algorithm is used to adjust the real-time speed of the truck to keep it consistent with the expected cruise speed.The hardware-in-the-loop test and real vehicle test of the cruise control system are carried out.The test results show that the developed cruise control strategy can realize the functions of acceleration and deceleration,speed recovery and predictive cruise,and can improve the safety and comfort of the whole vehicle.
