Method and device for detecting objects in the surroundings of a vehicle
First Claim
1. A method for detecting an object in the surrounding environment of a vehicle, comprising:
- transmitting a measuring signal having a predefined sampling rate;
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 a sampling rate of the measuring signal as a function of the determined distance between the vehicle and the object;
wherein the distance between the vehicle and the object is determined based on an actual received measuring signal which has the predefined sampling rate.

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.
