The invention relates to an ultra-wideband positioning method (1) for a positioning device (3) arranged in a motor vehicle (2), comprising the following steps: 1) establishing, by means of the positioning device (3), a bidirectional ultra-wideband data communication (7) between the positioning device (3) and at least one object (4) close to the motor vehicle (2) and capable of ultra-wideband communication, wherein a first position and trajectory (5) of the at least one object (4) relative to the motor vehicle (2) is determined by the positioning device (3) on the basis of data packets (8) exchanged within the framework of the ultra-wideband data communication (7), and 2) ultra-wideband positioning and distance measurement (9) are performed by the positioning device (3), wherein a second position and trajectory (6) of the at least one object (4) relative to the motor vehicle (2) is determined by the positioning device (3) in that at least one ultra-wideband transmission radio signal (30) is emitted by the positioning device (3) and a backscattered radio signal (31) thereof reflected back by the at least one object (4) is detected in a delayed manner. The invention also relates to a positioning device (3) for carrying out the ultra-wideband positioning method (1) and to a motor vehicle (2) comprising such a positioning device (3).
本发明涉及一种用于布置在机动车(2)中的定位装置(3)的超宽带定位方法(1),包括以下步骤:1)通过所述定位装置(3)在所述定位装置(3)与接近所述机动车(2)并且能够进行超宽带通信的至少一个对象(4)之间建立双向超宽带数据通信(7),其中通过所述定位装置(3)基于在所述超宽带数据通信(7)的框架内交换的数据包(8)确定所述至少一个对象(4)相对于所述机动车(2)的第一位置和轨迹(5),以及2)通过所述定位装置(3)执行超宽带定位和距离测量(9),其中通过所述定位装置(3)确定所述至少一个对象(4)相对于所述机动车(2)的第二位置和轨迹(6),具体方式为,通过所述定位装置(3)发射至少一个超宽带发射无线电信号(30)并且延时检测其被所述至少一个对象(4)反射回来的反向散射无线电信号(31)。本发明还涉及一种用于执行所述超宽带定位方法(1)的定位装置(3)以及一种包括这种定位装置(3)的机动车(2)。
