Abstract
Systems and methods for real time routing of vehicles. In particular, systems and methods are provided for real time routing of vehicles based on encounters with vulnerable road users. Vehicle perception and communication systems can provide live feedback of vulnerable road user locations. Various vulnerable road user behaviors can be identified by vehicle perception systems and flagged for avoidance in a central mapping system. The feedback can be used to route other fleet vehicles around the vulnerable road users.
Claims20
A method for vehicle routing in a fleet of vehicles, comprising:
- detecting, at a first vehicle, a road user;
- identifying, at a first vehicle perception system, a high-risk situation based on a behavior of the road user;
- logging a time, location, and type of the high-risk situation in a vehicle event log at the first vehicle;
- transmitting the vehicle event log for the high-risk situation to a dispatch service;
- identifying a subset of vehicles in the fleet of vehicles with planned routes near the high-risk situation;
- and
- determining, for each vehicle in the subset of vehicles, a respective updated route.
A system for vehicle routing in a fleet of vehicles, comprising:
- a first vehicle in the fleet, including:
- a sensor suite including external vehicle sensors to sense a vulnerable road user and generate sensor data;
- a perception system to identify a high-risk situation based on the sensor data and generate a vehicle event log including a time, a location and a type of the high-risk situation;
- an onboard computer to transmit the vehicle event log;
- and
- a dispatch service to:
- receive the vehicle event log for the high-risk situation;
- identify a subset of vehicles in the fleet of vehicles having planned routes near the high-risk situation;
- and
- determine, for each vehicle in the subset of vehicles, a respective updated route.
A method for real time vehicle routing in a fleet of vehicles, comprising:
- receiving a vehicle event log for a high-risk situation at a dispatch service, wherein the vehicle event log includes a time, a location, and type of the high-risk situation;
- identifying a first vehicle in the fleet of vehicles having a planned route near the high-risk situation;
- identifying, for the first vehicle, a set of alternate routes including a detour around the high-risk situation;
- and
- selecting, for the first vehicle, a respective updated route from the set of alternate routes.
