Abstract
A radar sensing system for a vehicle includes a radar sensor disposed at the vehicle so as to have a field of sensing exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals. The received radio signals are transmitted radio signals that are reflected from an object. A control has a processor for processing outputs of the receivers. The transmitted radio signals reflect off a radar reflective object, which includes one of radar reflective road markings or radar reflective signs. The control, via processing of outputs of the receivers by the processor, determines information pertaining to the radar reflective object based on the reflected radio signals.
Claims22
A radar sensing system for a vehicle, the radar sensing system comprising:
- a radar sensor disposed at the vehicle so as to have a field of sensing exterior of the vehicle;
- wherein the radar sensor comprises a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals, and wherein the received radio signals are transmitted radio signals that are reflected from an object;
- a control having a processor for processing outputs of the receivers;
- wherein the transmitted radio signals reflect off at least one radar reflective object disposed in the field of sensing of the radar sensor;
- wherein the at least one radar reflective object comprises radar reflective traffic lane demarcations on a road being traveled by the vehicle;
- wherein the control, responsive to processing of outputs of the receivers by the processor, determines information pertaining to the radar reflective traffic lane demarcations based on the received reflected radio signals;
- and
- a display, wherein the display, when visibility of the radar reflective traffic lane demarcations to a driver of the vehicle is compromised and responsive to the determined information pertaining to the radar reflective traffic lane demarcations, displays virtual traffic lane demarcations such that the virtual traffic lane demarcations appear to the driver of the vehicle to overlay the road along the visibility-compromised radar reflective traffic lane demarcations.
