Abstract
The disclosure includes embodiments for minimizing radar interference. In some embodiments, a method includes observing, for a time frame, an order in which Basic Safety Messages (“BSMs”) are received by a DSRC radio of the ego vehicle and broadcasted by the DSRC radio of the ego vehicle. In some embodiments, the method includes building a data structure that includes digital data that describes the order in which the BSMs were received and transmitted by the DSRC radio during the time frame. In some embodiments, the method includes assigning, by the onboard computer of the ego vehicle, radar parameters to the one or more other DSRC-enabled vehicles and the ego vehicle based on the order described by the digital data included in the data structure.
