Abstract
In control over a vehicle, inter-vehicle communication information of a preceding vehicle that runs ahead of the vehicle is acquired, follow-up running control for causing the vehicle to follow the preceding vehicle is executed on the basis of the inter-vehicle communication information, and, during the follow-up running control, a parameter used in the follow-up running control is determined on the basis of a condition in which the inter-vehicle communication information is acquired.
Claims8
A control device for a vehicle, the method comprising:
- acquiring inter-vehicle communication information of a preceding vehicle that runs ahead of the vehicle;
- executing follow-up running control that causes the vehicle to follow the preceding vehicle based on the inter-vehicle communication information;
- and
- during the follow-up running control, determining a value of a parameter used in the follow-up running control based on either
- (1) a duration of a communication breakdown determination time, which is a variable period of time in which it is determined whether communication with the preceding vehicle is lost, and which is used to determine whether there has been a breakdown of an inter-vehicle communication between the vehicle and the preceding vehicle, or
- (2) a target value of a rate of occurrence of the breakdown of the inter-vehicle communication, which is a rate at which it is determined that communication with the preceding vehicle is lost within a predetermined period of time, the target value being a variable value.

A control device for a vehicle, the control device comprising:
- an acquisition unit that acquires inter-vehicle communication information of a preceding vehicle that runs ahead of the vehicle;
- a running control unit that executes follow-up running control that causes the vehicle to follow the preceding vehicle based on the inter-vehicle communication information;
- and
- a determining unit that, during the follow-up running control, determines a parameter used in the follow-up running control based on either
- (1) a duration of a communication breakdown determination time, which is a period of time in which it is determined whether communication with the preceding vehicle is lost, and which is used to determine whether there has been a breakdown of an inter-vehicle communication between the vehicle and the preceding vehicle, or
- (2) a target value of a rate of occurrence of the breakdown of the inter-vehicle communication, which is a rate at which it is determined that communication with the preceding vehicle is lost within a predetermined period of time, the target value being a variable value.
