Abstract
Vehicle operation diagnosis devices, methods, and programs diagnose a driver's vehicle operation in a vehicle that is provided with an inter-vehicular distance control system. When an inter-vehicular distance between the driver's own vehicle and a vehicle ahead that is moving forward ahead of the driver's own vehicle is within a specified distance, the inter-vehicular distance between the driver's own vehicle and the vehicle ahead is controlled by performing deceleration control of the driver's own vehicle. The devices, methods, and programs acquire a first driving parameter and a second driving parameter and diagnose the driver's vehicle operation based on a difference between the first driving parameter and the second driving parameter.
Claims11
A vehicle operation diagnosis device that diagnoses a driver's vehicle operation in a vehicle that is provided with an inter-vehicular distance control system that, in a case where an inter-vehicular distance between the driver's own vehicle and a vehicle ahead that is moving forward ahead of the driver's own vehicle is within a specified distance, controls the inter-vehicular distance between the driver's own vehicle and the vehicle ahead by performing deceleration control of the driver's own vehicle, the vehicle operation diagnosis device comprising:
- a first driving parameter acquisition unit that acquires a first driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation;
- a second driving parameter acquisition unit that acquires a second driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation based on the inter-vehicular distance between the driver's own vehicle and the vehicle ahead being within the specified distance in accordance with a factor that is based on the vehicle ahead;
- and
- a vehicle operation diagnosis unit that diagnoses the driver's vehicle operation based on a difference between the first driving parameter and the second driving parameter.
-8. (canceled)
A vehicle operation diagnosis method that diagnoses a driver's vehicle operation in a vehicle that is provided with an inter-vehicular distance control system that, in a case where an inter-vehicular distance between the driver's own vehicle and a vehicle ahead that is moving forward ahead of the driver's own vehicle is within a specified distance, controls the inter-vehicular distance between the driver's own vehicle and the vehicle ahead by performing deceleration control of the driver's own vehicle, the vehicle operation diagnosis method comprising the steps of:
- acquiring a first driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation;
- acquiring a second driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation based on the inter-vehicular distance between the driver's own vehicle and the vehicle ahead being within the specified distance in accordance with a factor that is based on the vehicle ahead;
- and
- diagnosing the driver's vehicle operation based on a difference between the first driving parameter and the second driving parameter.
A computer program that is installed in a computer and that diagnoses a driver's vehicle operation in a vehicle that is provided with an inter-vehicular distance control system that, in a case where an inter-vehicular distance between the driver's own vehicle and a vehicle ahead that is moving forward ahead of the driver's own vehicle is within a specified distance, controls the inter-vehicular distance between the driver's own vehicle and the vehicle ahead by performing deceleration control of the driver's own vehicle, the computer program causing the computer to perform the functions of:
- acquiring a first driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation;
- acquiring a second driving parameter when the driver's own vehicle has traveled in a state in which the deceleration control by the inter-vehicular distance control system was in operation based on the inter-vehicular distance between the driver's own vehicle and the vehicle ahead being within the specified distance in accordance with a factor that is based on the vehicle ahead;
- and
- diagnosing the driver's vehicle operation based on a difference between the first driving parameter and the second driving parameter.
