VEHICULAR MITIGATION SYSTEM BASED ON WIRELESS VEHICLE DATA
First Claim
1. A method executed by an onboard vehicle computer system of an ego vehicle, the method comprising:
- receiving, via a Dedicated Short Range Communication (“
DSRC”
) module of the ego vehicle, a DSRC-based wireless message that includes wireless vehicle data and is wirelessly received via a DSRC channel of the DSRC module, wherein the DSRC-based wireless message and the wireless vehicle data are compliant with a DSRC standard regulating a transmission of the DSRC-based wireless message and content of the wireless vehicle data;
determining that the wireless vehicle data describes a presence of a traffic obstruction that is at a location downstream of the ego vehicle and within a same lane of travel as the ego vehicle, wherein the location is described by the wireless vehicle data with lane-level accuracy;
determining a preceding velocity of a preceding vehicle that is traveling directly in front of the ego vehicle; and
modifying an ego velocity of the ego vehicle based on the preceding velocity and the presence of the traffic obstruction, wherein the ego velocity is modified by the onboard vehicle computer system so that the ego velocity is substantially equal to the preceding velocity prior to the ego vehicle arriving at the location of the traffic obstruction and the ego vehicle does not collide with a set of downstream vehicles including the preceding vehicle.

Abstract
The disclosure includes embodiments for modifying the acceleration of an ego vehicle based on wireless vehicle data included in a wireless message. A method includes receiving the wireless message that includes wireless vehicle data that describes one or more physical properties of a downstream vehicle. The wireless vehicle data indicates a presence of a traffic obstruction. The method includes determining a modification for an acceleration of the ego vehicle based on the wireless vehicle data and the indication of the traffic obstruction. The method includes modifying the acceleration of the ego vehicle based on wireless vehicle data compliant with the DSRC standard. The modified acceleration causes the ego vehicle to travel at a velocity consistent with a preceding vehicle and the downstream vehicle so that the ego vehicle does not collide with the preceding vehicle or the other downstream vehicle, which are in the same lane as the ego vehicle.
