Abstract
A method and a device for detecting objects in the blind spot of a vehicle are provided, which make it possible, through an adaptively decreased measuring time, to achieve a shorter response time for alerting a driver in the event of an imminent collision with an object in the blind spot. Due to the fact that the frequency and/or the width of a measuring signal is/are set as a function of the previously determined distance between the vehicle and the object, it is possible to increase the sampling rate proportional to the decrease in the distance between the vehicle and the object. This makes it possible to detect the closest object more rapidly, i.e., for the most relevant object for a potential collision to be evaluated, thereby generating an adequately early collision alert. The frequency of a measuring signal is preferably set reciprocally proportional to the determined distance between the vehicle and the object.

13. A method for detecting an object in the surrounding environment of a vehicle, comprising:
-
transmitting a measuring signal having a predefined frequency and a predefined width;
receiving, within a predefined time interval subsequent to the transmission of the measuring signal, the measuring signal that has been at least one of reflected and scattered by an object in the surrounding environment of the vehicle;
determining a distance between the vehicle and the object based on the received measuring signal; and
setting at least one of a frequency and a width of the measuring signal as a function of the determined distance between the vehicle and the object. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A system for detecting an object in the surrounding environment of a vehicle, comprising:
-
a transmitter for transmitting a measuring signal having a predefined frequency and a predefined width;
a receiver for receiving, within a predefined time interval subsequent to the transmission of the measuring signal, the measuring signal that has been at least one of reflected and scattered by an object in the surrounding environment of the vehicle;
an analyzer for determining a distance between the vehicle and the object based on the received measuring signal, wherein the analyzing unit is operatively coupled to the transmitter and the receiver; and
a control unit for setting at least one of a frequency and a width of the measuring signal as a function of the determined distance between the vehicle and the object, wherein the control unit is operatively coupled to at least the analyzer and the transmitter. - View Dependent Claims (21, 22, 23, 24)
