Abstract
Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to utilize vehicle external sensor data, vehicle internal sensor data, vehicle capabilities and external V2X input to determine, send, receive and utilize V2X information and control data, sent between the vehicle and a road side unit (RSU) to determine intersection access and vehicle behavior when approaching the intersection.
Claims30
A method of intersection access by an ego vehicle, comprising:
- determining a braking distance for the ego vehicle based upon vehicle external sensor data, vehicle internal sensor data, vehicle capabilities, or external V2X input, or a combination thereof, wherein the braking distance for the ego vehicle is based, at least in part, on tire pressure for the ego vehicle or tire traction data or a combination thereof;
- sending, from the ego vehicle to a roadside unit (RSU), a first message, wherein the first message comprises an identification data element for the ego vehicle and a braking distance data element for the ego vehicle;
- receiving, from the RSU, a second message comprising one or more instructions with respect to intersection access by the ego vehicle, based at least in part upon the braking distance for the ego vehicle;
- and
- controlling the intersection access by the ego vehicle in response to the one or more instructions received from the RSU.
2 more elements
An ego vehicle, comprising:
- one or more wireless transceivers;
- vehicle internal sensors;
- vehicle external sensors;
- memory;
- and
- one or more processors, communicatively coupled to the one or more wireless transceivers, the vehicle internal sensors, the vehicle external sensors, and the memory, and wherein the one or more processors are configured to:
- determine a braking distance for the ego vehicle based upon data from the vehicle external sensors, data from the vehicle internal sensors, vehicle capabilities, or external V2X input, or a combination thereof, wherein the braking distance for the ego vehicle is based, at least in part, on tire pressure for the ego vehicle or tire traction data or a combination thereof;
- send, from the ego vehicle to a roadside unit (RSU), a first message, wherein the first message comprises an identification data element for the ego vehicle and a braking distance data element for the ego vehicle;
- receive, from the RSU, a second message comprising one or more instructions with respect to intersection access by the ego vehicle, based at least in part upon the braking distance for the ego vehicle;
- and
- control the intersection access by the ego vehicle in response to the one or more instructions received from the RSU.
8 more elements
An ego vehicle, comprising:
- means for determining a braking distance for the ego vehicle based upon vehicle external sensors data, vehicle internal sensors data, vehicle capabilities, or external V2X input, or a combination thereof, wherein the braking distance for the ego vehicle is based, at least in part, on tire pressure for the ego vehicle or tire traction data or a combination thereof;
- means for sending, from the ego vehicle to a roadside unit (RSU), a first message, wherein the first message comprises an identification data element for the ego vehicle and a braking distance data element for the ego vehicle;
- means for receiving, from the RSU, a second message comprising one or more instructions with respect to intersection access by the ego vehicle, based at least in part upon the braking distance for the ego vehicle;
- and
- means for controlling the intersection access by the ego vehicle in response to the one or more instructions received from the RSU.
2 more elements
A non-transitory computer-readable medium, having stored thereon computer-readable instructions to cause one or more processors on an ego vehicle to:
- determine a braking distance for the ego vehicle based upon vehicle external sensor data, vehicle internal sensor data, vehicle capabilities, or external V2X input, or a combination thereof, wherein the braking distance for the ego vehicle is based, at least in part, on tire pressure for the ego vehicle or tire traction data or a combination thereof;
- send, from the ego vehicle to a roadside unit (RSU), a first message, wherein the first message comprises an identification data element for the ego vehicle and a braking distance data element for the ego vehicle;
- receive, from the RSU, a second message comprising one or more instructions with respect to intersection access by the ego vehicle, based at least in part upon the braking distance for the ego vehicle;
- and
- control the intersection access by the ego vehicle in response to the one or more instructions received from the RSU.
