The invention discloses a method for controlling the speed of a vehicle passing through a speed bump based on comfort optimization, and the method comprises the following steps: if the speed bump exists in front of a current driving route of the vehicle, an ECU control module recognizes and obtains a real-time distance between a front axle of the vehicle and the speed bump; the vehicle speed, the calculated maximum vibration amplitude of the vertical direction of the tire and the vibration frequency of the maximum vibration amplitude of the vertical direction of the tire are input into a preset deceleration strip area recognition model based on an SVM algorithm, the vehicle-mounted equipment obtains a motion detection signal collected by at least one motion detection sensor in real time, and an ECU control module selects a corresponding deceleration strategy according to Vc. The collected test data comprises the vehicle speed, the vehicle speed vertical acceleration and the tire vertical displacement. The attention of a vehicle owner to the vehicle speed when the vehicle passes through the deceleration strip is improved, and the traffic accident rate caused by the too high vehicle speed can be effectively reduced.
本发明公开了一种基于舒适性优化的车辆通过减速带的车速控制方法,包括以下步骤:若当前车辆的行驶路线前方存在减速带,ECU控制模块识别得到车辆前轴与减速带的实时距离,将车速、经过计算得到的轮胎垂向最大振动振幅、轮胎垂向最大振幅振频输入预设的基于SVM算法的减速带区域识别模型,车载设备获取至少一个运动检测传感器实时采集的运动检测信号,ECU控制模块根据Vc选择相应的减速策略,以控制车身稳定控制模块对车辆减速,采集的试验数据包括车速、车速垂向加速度和轮胎垂向位移。提高了车辆过减速带时车主对车速的注意力,可以有效降低由于车速过快而导致的交通事故发生率。
