A system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of the vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameters include at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, an angle of travel of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.
一种根据本公开的系统包括致动器控制模块和阻尼比模块。该致动器控制模块被配置为控制车辆的致动器,以使车辆通过绕其横摆轴线旋转来执行横摆操纵。该阻尼比模块被配置为基于在横摆操纵期间测量的工作参数来确定阻尼比。该工作参数包括以下各项中的至少一项:车辆的横摆率、连接至车辆的拖车的横摆率、车辆的横向加速度、拖车的横向加速度、车辆的行进角、以及车辆的纵向轴线与拖车的纵向轴线之间的挂钩角。
