Patent ID: 11919528
Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHA
Field: Transport (Mechanical engineering)
Classification: CPC B  H | IPC B  H

Claim 1:
2. A vehicle control method that uses communication between a first vehicle and a second vehicle, the first vehicle includes a communication device configured to send and receive vehicle-to-vehicle communication information, a memory configured to store the vehicle-to-vehicle communication information, and a processor configured to perform abnormal traveling determination processing for determining whether the first vehicle is travelling abnormally, the second vehicle includes a communication device configured to send and receive the vehicle-to-vehicle communication information, a memory configured to store the vehicle-to-vehicle communication information and driving environment information on the second vehicle, and a processor configured to perform objective determination processing for determining whether the first vehicle is traveling abnormally, the vehicle control method comprising,
by the processor of the second vehicle,
acquiring the driving environment information on the second vehicle;
performing objective determination processing for objectively determining whether the first vehicle is traveling abnormally based on the driving environment information; and
generating an objective determination result as the vehicle-to-vehicle communication information to be sent to the first vehicle;
sending the objective determination result to the first vehicle, the objective determination result indicating a result of the objective determination processing; and

by the processor of the first vehicle,
receiving the objective determination result;
determining whether the first vehicle is traveling abnormally based on the objective determination result; and
performing emergency vehicle control for the first vehicle when it is determined that the first vehicle is traveling abnormally, wherein:

the memory of the first vehicle is configured to further store driving environment information on the first vehicle;
the abnormal traveling determination processing is configured to include subjective determination processing for subjectively determining whether the first vehicle is traveling abnormally;
the processor of the first vehicle is configured to determine, in the subjective determination processing, whether the first vehicle is traveling abnormally based on the driving environment information on the first vehicle;
the processor of the first vehicle is configured to comprehensively determine, in the abnormal traveling determination processing, whether the first vehicle is traveling abnormally based on the objective determination result and on a subjective determination result, the subjective determination result indicating a result of the subjective determination processing;
the processor of the first vehicle is configured to comprehensively determine, in the abnormal traveling determination processing, whether the first vehicle is traveling abnormally based on a calculation expression represented using the subjective determination result, the objective determination result, and weighting coefficients of the subjective determination result and the objective determination result; and
the weighting coefficients are changed based on the driving environment information on the first vehicle.
