The invention relates to low-speed maneuver assistance for a vehicle. A maneuver assistance system (100) for a vehicle combination (190) includes: an interface (110) configured to receive a measurement (z1) from a camera (191); a processing circuit (120) implementing a Kalman filter (121) configured to observe an articulation angle (phi) of the vehicle combination based on measurements from the camera; a signal analyzer (130) configured to repeatedly estimate signal noise measured by the camera and adjust the Kalman filter based on statistics derived from the estimated signal noise; and an assist unit (140) configured to receive the estimate of the articulation angle from the Kalman filter and to provide a driving action (u) based thereon.
本申请涉及用于车辆的低速操纵辅助。一种车辆组合(190)的操纵辅助系统(100)包括:接口(110),被配置成从相机(191)接收测量(z1);处理电路(120),实施卡尔曼滤波器(121),该卡尔曼滤波器被配置成基于来自相机的测量而观察车辆组合的铰接角(φ);信号分析器(130),被配置成重复估计相机测量的信号噪声,并基于从所估计的信号噪声导出的统计而调整卡尔曼滤波器;以及辅助单元(140),被配置成从卡尔曼滤波器接收铰接角的估计并基于此而提供驾驶动作(u)。
