Abstract
Embodiments include systems and methods for automatically populating a safety message, such as a Basic Safety Message (BSM), with a position and combined length of a vehicle and a towed object. Some embodiments include determining a distance from one or more antennas coupled to a receiver in the vehicle to a remote sensor on the towed object by processing short-range wireless signals received from the remote sensor. Some embodiments include populating the safety message with a position of the vehicle and the towed object based on the determined distance from the one or more antennas to the remote sensor.
Claims19
A method performed by one or more processing systems of a vehicle connected to a towed object, comprising:
- determining a distance from one or more antennas coupled to a receiver in the vehicle to a remote sensor on the towed object by processing short-range wireless signals received from the remote sensor, wherein the remote sensor is a camera, and the short-range wireless signals encode image data from the camera;
- populating safety messages with a position of the vehicle and the towed object based on the determined distance from one or more antennas coupled to the receiver to the remote sensor;
- processing the short-range wireless signals received from the remote sensor to determine whether movement of the towed object relative to one or more antennas coupled to the receiver in the vehicle satisfies a dangerous or critical vehicle movement criterion;
- and
- including an indication of a critical event flag in the safety message in response to determining that the movement of the towed object relative to one or more antennas coupled to the receiver in the vehicle satisfies the dangerous or critical vehicle movement criterion.
A processing system for use in a vehicle, comprising:
- one or more transceivers configured to be coupled to one or more antennas on the vehicle;
- and
- a processor coupled to the one or more transceivers and configured with processor-executable instructions to:
- determine a distance from the one or more antennas to a remote sensor on a towed object by processing short-range wireless signals received from the remote sensor, wherein the remote sensor is a camera, and the short-range wireless signals encode image data from the camera;
- populate safety messages with a position of the vehicle and the towed object based on the determined distance from the one or more antennas to the remote sensor;
- process the short-range wireless signals received from the remote sensor to determine whether movement of the towed object relative to the one or more antennas on the vehicle satisfies a dangerous or critical vehicle movement criterion;
- and
- include an indication of a critical event in the safety messages in response to determining that the movement of the towed object relative to the one or more antennas on the vehicle satisfies the dangerous or critical vehicle movement criterion.
A processing system for use in a vehicle, comprising:
- one or more antennas coupled to one or more transceivers;
- means for determining a distance from the one or more antennas on the vehicle to a remote sensor on a towed object by processing short-range wireless signals received from the remote sensor, wherein the remote sensor is a camera, and the short-range wireless signals encode image data from the camera;
- means for populating safety messages with a position of the vehicle and the towed object based on the determined distance from the one or more antennas to the remote sensor;
- means for processing the short-range wireless signals received from the remote sensor to determine whether movement of the towed object relative to the one or more antennas satisfies a dangerous or critical vehicle movement criterion;
- and
- means for including an indication of a critical event in the safety messages in response to determining that the movement of the towed object relative to the one or more antennas satisfies the dangerous or critical vehicle movement criterion.
A non-transitory processor-readable medium having stored thereon processor-executable instructions configured to cause a processor of a vehicle processing system to perform operations comprising:
- determine a distance from one or more antennas coupled to a receiver in the vehicle to a remote sensor on a towed object by processing short-range wireless signals received from the remote sensor, wherein the remote sensor is a camera, and the short-range wireless signals encode image data from the camera;
- populating a safety message with a position of the vehicle and the towed object based on the determined distance from the one or more antennas to the remote sensor;
- processing the short-range wireless signals received from the remote sensor to determine whether movement of the towed object relative to one or more antennas coupled to the receiver in the vehicle satisfies a dangerous or critical vehicle movement criterion;
- and
- including an indication of a critical event flag in the safety message in response to determining that the movement of the towed object relative to one or more antennas coupled to the receiver in the vehicle satisfies the dangerous or critical vehicle movement criterion.
