Multi-level disengagement service for autonomous vehicles

A roadside unit (RSU) of an intelligent transportation infrastructure system, the RSU comprising:

• a processor located separate from a vehicle;
• and
• a non-transitory computer-readable storage medium located separate from the vehicle and including instructions that, when executed by the processor, cause the processor to:
• receive, from the vehicle having autonomous driving capabilities, an autonomous driving disengagement request message;
• determine, based on perception data or analytics related to the vehicle or a vicinity of the vehicle, a disengagement level of a multiple-disengagement-level protocol and a corresponding post-disengagement vehicle action, wherein the multiple-disengagement-level protocol comprises disengagement levels DL-1 through DL-6, each disengagement level being associated with a different urgency level and a different post-disengagement vehicle action;
• and
• transmit to the vehicle an autonomous driving disengagement response message including a post-disengagement vehicle action instruction.

A non-transitory computer-readable storage medium of an intelligent transportation infrastructure system having stored therein program instructions that when executed by processing circuitry, cause the processing circuitry to:

• receive from a vehicle having autonomous driving capabilities, an autonomous driving disengagement request message;
• determine, based on perception data or analytics related to the vehicle or a vicinity of the vehicle, a disengagement level of a multiple-disengagement-level protocol and a corresponding post-disengagement vehicle action, wherein the multiple-disengagement-level protocol comprises disengagement levels DL-1 through DL-6, each disengagement level being associated with a different urgency level and a different post-disengagement vehicle action;
• and
• transmit to the vehicle an autonomous driving disengagement response message including a post-disengagement vehicle action instruction,
• wherein the storage medium is located in a roadside unit (RSU) separate from the vehicle, and wherein the processing circuitry is located in the RSU.
