Abstract
Exemplary embodiments described in this disclosure are generally directed to vehicle detection systems and methods. In one exemplary embodiment, a vehicle detection system that is provided in a first vehicle receives a map generated by a vehicle detection system of a second vehicle. The map, which can be a cardinal map, for example, indicates a third vehicle that is detected by the vehicle detection system of the second vehicle and is undetectable by the first vehicle due to various reasons. For example, the first vehicle may fail to detect the third vehicle due to signal blocking caused by an intervening vehicle located between the first vehicle and the third vehicle, or due to the loss of radio-frequency (RF) signal reception by the vehicle detection system in the first vehicle. The second vehicle can detect the third vehicle by using radio-frequency (RF) signals and to convey the information to the first vehicle.
