Abstract
A radar system (2) for a vehicle (1), having a radar transceiver (3) and a control unit (4), where the control unit (4) is adapted to control the radar transceiver to apply an initial signal power level (Pi) for transmitted radar signals (5); and to receive reflected radar signals (6) that have been reflected by at least one object (7). The control unit (4) is further adapted to determine a total signal reduction level (L) for which at least one predetermined criterion is not met; to compare the total signal reduction level (L) to a threshold; and to determine whether the radar transceiver (3) is working in an acceptable manner or not in dependence of the comparison.
Claims15
A radar system for a vehicle, comprising a radar transceiver and a control unit, where the control unit is adapted to control the radar transceiver to:
- apply an initial signal power level for transmitted radar signals;
- and to
- receive reflected radar signals that have been reflected by at least one object;
- wherein the control unit is further adapted to:
- determine a total signal reduction level for which at least one predetermined criterion is not met;
- compare the total signal reduction level to a threshold providing a comparison;
- and to
- determine whether the radar transceiver is working in an acceptable manner or not in dependence of the comparison.
A method for controlling the function of a vehicle radar transceiver, where the method comprises the steps of:
- transmitting radar signals using an initial signal power level;
- and
- receiving reflected radar signals that have been reflected by an object,
- wherein the method further comprises:
- determining a total signal reduction level for which at least one predetermined criterion is not met;
- comparing the total signal reduction level to a threshold providing a comparison;
- and
- determining whether the radar transceiver is working in an acceptable manner or not in dependence of the comparison.
