Abstract
An object relative status determination system (54) for a vehicle (52) includes an orthogonal frequency domain modulation (OFDM) transceiver (56) that generates an object range signal (83). The system (54) may also include a global navigation system (GNS) (58) that receives a satellite range signal (70). A controller (66) is coupled to the OFDM transceiver (56) and the GNS (58) and determines object information relative to the vehicle (52) in response to the object range signal (83) and the satellite range signal (70).
Claims19
An object relative status determination system for at least one vehicle, said system comprising:
- at least one orthogonal frequency domain modulation (OFDM) transceiver operable to transmit and receive object range signals onboard a host vehicle;
- and
- at least one controller coupled to said at least one OFDM transceiver and operable to determine object information relative to said host vehicle in response to said object range signals.
An object relative status determination system for at least one vehicle, said system comprising:
- at least one OFDM transceiver operable to transmit and receive object range signals;
- at least one global positioning system (GPS) operable to receive satellite range signals;
- and
- at least one controller coupled to said at least one OFDM transceiver and said at least one GPS and operable to determine object information relative to a host vehicle in response to said satellite range signals and said object range signals.
A system comprising:
- a host vehicle;
- an orthogonal frequency domain modulation (OFDM) transceiver onboard said host vehicle;
- a global positioning system (GPS) unit onboard said host vehicle;
- at least one collision countermeasure onboard said host vehicle;
- and
- a controller coupled to said OFDM transceiver, said GPS unit, and said at least one collision countermeasure onboard said host vehicle;
- wherein said OFDM transceiver is operable to transmit and receive range signals to and from at least one object having a reciprocal transceiver;
- wherein said GPS unit is operable to receive range signals from at least one satellite that is wirelessly linked to said at least one object;
- wherein said controller is operable to process said range signals and thereby determine the range of said at least one object relative to said host vehicle;
- and
- wherein said controller is operable to selectively control said at least one collision countermeasure according to said range as determined.
