20230060940 · 2023-03-02 ·

A system for determining a content of a message used to coordinate interactions among vehicles can include a processing device and a memory. The memory can store a discretization module and a communications module. The discretization module can include instructions that when executed by the processing device cause the processing device to: (1) analyze a critical maneuver trajectory of an ego vehicle and a current trajectory of another vehicle to determine an existence of a critical maneuver situation and (2) produce a discretized representation of a portion of the critical maneuver trajectory of the ego vehicle. A form of the discretized representation can be based on the existence of the critical maneuver situation. The communications module can include instructions that when executed by the processing device cause the processing device to communicate the discretized representation as the content of the message used to coordinate interactions among vehicles.

20230113819 · 2023-04-13 ·

A suspension system and associated control methods for improving the effectiveness of driver assistance systems is disclosed where the driver assistance systems can generate and send requests to a suspension control unit (SCU) of the suspension system to actuate (e.g., close) one or more comfort valves in the suspension system to increase the roll stiffness and/or pitch stiffness of the suspension system when the driver assistance systems are taking corrective action. As part of a two-way communication between the suspension control unit (SCU) and the driver assistance systems, the suspension control unit (SCU) communicates target stiffnesses and/or calculated effective stiffnesses to the driver assistance systems, which is used to update the vehicle stability models used by the driver assistance systems.

Collision avoidance planning system

Techniques for controlling a vehicle based on a collision avoidance algorithm are discussed herein. The vehicle receives sensor data and can determine that the sensor data represents an object in an environment through which the vehicle is travelling. A computing device associated with the vehicle determines a collision probability between the vehicle and the object at predicted locations of the vehicle and object at a first time. Updated locations of the vehicle and object can be determined, and a second collision probability can be determined. The vehicle is controlled based at least in part on the collision probabilities.
