Abstract
A method and a device for acquiring and evaluating objects in the area surrounding a vehicle, in which, using at least one radar sensor, the target objects in a monitoring area are acquired, and in at least one evaluation unit the distance data and/or velocity data of the target objects are evaluated. The acquisition of the target objects takes place within a virtual barrier that can be modified in its distance from the vehicle and in its length, and, using a transmission signal of a pulse radar sensor, the receive signal reflected from the target object can be evaluated in one or more receive channels so that different locus resolutions and different dimensions with respect to the distance and the length of the virtual barrier can be achieved.
Claims22
A method for detecting and evaluating at least one target object in an area surrounding a vehicle, comprising:
- (a) acquiring the at least one target object in a monitoring area by using at least one radar sensor, and
- (b) evaluating at least one of distance data and velocity data of the at least one target object in at least one evaluation arrangement;
- wherein the velocity data of the at least one target object is acquired within a virtual barrier that is modifiable in a first distance of the virtual barrier from the vehicle and in a length of the virtual barrier.
A device for acquiring and evaluating objects in an area surrounding a vehicle, comprising:
- an acquiring arrangement to acquire at least one target object in a monitoring area;
- and
- an evaluating arrangement to evaluate at least one of distance data and velocity data of the at least one target object;
- wherein:
- the velocity data of the at least one target object is acquired within a virtual barrier that is modifiable in a first distance from the vehicle and a length of the virtual barrier;
- and
- the acquiring arrangement includes at least one pulse radar sensor, a first receive channel, at least another receive channel, and a pulse generator, to provide modulated carrier pulses for a signal of a radar transmitter and to provide demodulation in the first receive channel and the at least another receive channel.
