    • A plurality of sensor units (1, 5, 9, 13) are provided, at least one for mounting on or in the 5 vicinity of the front axle of a vehicle and at least one for mounting on or in the vicinity of the rear axle of the vehicle. Each sensor unit comprises a first ultrasonic transducer mounted so as to emit a signal in a first direction (2, 6, 10, 14) in order to measure a first distance and a second ultrasonic transducer mounted so as to emit a signal in a second direction (3, 75 11, 15) in order to measure a second distance. The sensor units are operable under control of a central processing unit (19), a control panel and display screen, connected to or integral with the CPU, all for mounting in or on the vehicle so that the first transducers provide data on the distance between the vehicle and adjacent objects as a parking aid, while the second transducers provide data on the distance between part of the vehicle and the ground as a measure of the loading of the vehicle. Preferably four sensor units are provided, two (9, 13) for mounting to the vehicle substantially symmetrically in the vicinity of the front axle, and two (1, 5) for mounting to the vehicle substantially symmetrically in the vicinity of the rear axle.
    • 设置有多个传感器单元(1,5,9,13),至少一个传感器单元用于安装在车辆前轴的5附近或其附近,并且至少一个用于安装在后桥上或附近 的车辆。 每个传感器单元包括安装成在第一方向(2,6,10,14)上发射信号以便测量第一距离的第一超声波换能器和安装成在第二方向上发射信号的第二超声波换能器 方向(3,75,115),以便测量第二距离。 传感器单元可在中央处理单元(19),控制面板和显示屏幕的控制下操作,所述中央处理单元(19),连接到CPU或与CPU集成在一起,全部用于安装在车辆中或车辆上,使得第一换能器提供关于 车辆和相邻物体作为停车辅助装置,而第二换能器提供车辆部分与地面之间的距离的数据作为车辆载荷的量度。 优选地,设置有四个传感器单元,两个(9,13),用于在前轴附近大致对称地安装到车辆,以及两个(1,5)用于在后轴附近基本对称地安装到车辆。
