METHOD AND ENVIRONMENT DETECTION DEVICE FOR DETERMINING THE POSITION AND/OR THE MOVEMENT OF AT LEAST ONE OBJECT IN THE ENVIRONMENT OF A VEHICLE BY MEANS OF ACOUSTIC SIGNALS REFLECTED BY THE OBJECT

摘要

The present invention relates to the vehicles of the object in a kind of measurement at accommodation and/or at least one mobile environment, especially in vehicle, pass through the acoustical signal reflected by the object, hereinafter referred to as echo-signal. The amplification of the echo-signal each received and amplification coefficient depends on the corresponding echo-signal of runing time and is exaggerated multiple measurement channels of echo-signal being converted into measuring signal with scheduled first dynamic range (micron) discretization according to its value and/or time, and each measuring signal is mapped to the device of the processing of the second dynamic range with the first dynamic range, compared to the first wide dynamic range, in this way, it is handled, and is at least temporarily used simultaneously using processing unit. The invention further relates to the corresponding environmental detection sets and vehicle detection apparatus for implementing this method, including environment. According to the present invention,
