Driver assistance device having a plurality of ultrasound sensors and vehicle having such a driver assistance device and method for operating a driver assistance device

摘要

The invention relates to a driver assistance device (2) having a plurality of ultrasound sensors, wherein at least one first ultrasound sensor (8 to 11, 17, 18, 21 to 24) has a normal mode as an operating mode in which transmitted ultrasound signals are unencoded and/or in which the first ultrasound sensor (8 to 11, 17, 18, 21 to 24) is designed for receiving unencoded ultrasound signals, and at least one second ultrasound sensor (6, 7, 13 to 16, 19, 20) can be operated in two different operating modes and has the normal mode as a first operating mode and has a special mode as a second operating mode, in which transmitted ultrasound signals are encoded and/or in which the second ultrasound sensor (6, 7, 13 to 16, 19, 20) is designed for receiving encoded ultrasound signals. The invention also relates to a vehicle (1) having a driver assistance device (2) and a method for operating a driver assistance device (2).

主权项

1. A driver assistance device comprising:
a plurality of ultrasound sensors, wherein at least one first ultrasound sensor has only a normal mode as an operating mode, wherein, in the normal mode, unencoded ultrasound signals are transmitted and received, and at least one second ultrasound sensor is operable in two different operating modes comprising the normal mode as a first operating mode, and a special mode as a second operating mode, wherein, in the special mode, encoded ultrasound signals are transmitted and received.
