US 2026/0112273 A1 · COLLISION AVOIDANCE SYSTEM

Abstract

A vehicle may include a primary system for generating data to control the vehicle and a secondary system that validates the data and/or other data to avoid collisions. For example, the primary system may localize the vehicle, detect an object around the vehicle, predict an object trajectory, and generate a trajectory for the vehicle. The secondary system may localize the vehicle, detect an object around the vehicle, predict an object trajectory, and evaluate a trajectory generated by the primary system. The secondary system may also monitor components of the vehicle to detect an error. If the secondary system detects an error with a trajectory generated by the primary system and/or an error with a component of the vehicle, the secondary system may cause the vehicle to perform a maneuver, such as decelerating, changing lanes, swerving, etc.

Dependent claims

A vehicle system comprising:

a second system in a vehicle communicatively coupled to a first system in the vehicle, the second system comprising one or more processors and memory having instruction stored thereon which cause the second system to perform operations comprising:
receiving at least a portion of sensor data;
outputting data indicating at least one of a characteristic of an object, a track for the object, or an object trajectory for the object;
receiving a trajectory for controlling the vehicle and from the first system;
performing one or more validation operations with the trajectory to determine a state associated with the trajectory, the state indicating an error associated with the first system causing the trajectory to be unsafe for controlling the vehicle;
and
outputting, based at least in part on the state, an output trajectory for the vehicle, the output trajectory comprising at least the trajectory,
wherein the second system is configured to send a message to the first system including an indication of the error associated with the first system.

A method comprising:

receiving, at a second system in a vehicle communicatively coupled to a first system in the vehicle, at least a portion of sensor data;
outputting data indicating at least one of a characteristic of an object, a track for the object, or an object trajectory for the object;
receiving a trajectory for controlling the vehicle and from the first system;
performing one or more validation operations with the trajectory to determine a state associated with the trajectory, the state indicating an error associated with the first system causing the trajectory to be unsafe for controlling the vehicle;
and
outputting, based at least in part on the state, an output trajectory for the vehicle, the output trajectory comprising at least the trajectory,
wherein the second system is configured to send a message to the first system including an indication of the error associated with the first system.

4 more elements

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

receiving, at a second system in a vehicle communicatively coupled to a first system in the vehicle, at least a portion of sensor data;
outputting data indicating at least one of a characteristic of an object, a track for the object, or an object trajectory for the object;
receiving a trajectory for controlling the vehicle and from the first system;
performing one or more validation operations with the trajectory to determine a state associated with the trajectory, the state indicating an error associated with the first system causing the trajectory to be unsafe for controlling the vehicle;
and
outputting, based at least in part on the state, an output trajectory for the vehicle, the output trajectory comprising at least the trajectory,
wherein the second system is configured to send a message to the first system including an indication of the error associated with the first system.
