Abstract

A control device of a vehicle includes a power source and a power transmission device, and comprises: a state determining portion determining whether a vehicle state is a state in which a running performance of the vehicle is limited; a drive torque calculating portion calculating a drive torque as a maximum drive torque which the vehicle outputs based on the vehicle state; a remaining running distance calculating portion calculating a remaining distance as a maximum distance for which the vehicle travels based on the vehicle state; a destination setting portion setting a destination of the vehicle based on the drive torque and the remaining distance; and a driving control portion providing an automatic driving control in which acceleration/deceleration and steering are automatically performed based on the destination when it is determined that the vehicle is in a state in which the running performance thereof is limited.

First claim

What is claimed is:

1. A control device of a vehicle including a power source and a power transmission device transmitting a power of the power source to drive wheels, the control device comprising:
a controller that is configured to:
determine whether a vehicle state is a state in which a running performance of the vehicle is limited;
calculate a drive torque as a maximum drive torque which the vehicle outputs based on the vehicle state;
calculate a remaining distance as a maximum distance for which the vehicle travels based on the vehicle state;
set a destination of the vehicle based on the drive torque and the remaining distance; and
provide an automatic driving control in which acceleration/deceleration and steering are automatically performed based on the destination when it is determined that the vehicle is in a state in which the running performance thereof is limited.

2. The control device of the vehicle according to claim 1 , wherein
the power source includes an engine and a rotating machine, and
the controller is configured to provide the automatic driving control using at least one of the engine and the rotating machine based on the vehicle state.

3. The control device of the vehicle according to claim 1 , wherein the controller is configured to set the destination based on a type of a road on which the vehicle is currently running.

4. The control device of the vehicle according to claim 3 , wherein the controller is configured to set the destination such that the vehicle runs to the destination on a road other than an expressway rather than on the expressway.

5. The control device of the vehicle according to claim 1 , wherein the controller is configured to set a place having high priority as the destination among predefined prioritized places.

6. The control device of the vehicle according to claim 5 , wherein the controller is configured to consider a predefined place for repairing the vehicle as the place having the highest priority when the controller sets the destination.

7. The control device of the vehicle according to claim 1 , wherein the controller is configured to provide the automatic driving control by controlling the power transmission device based on a type of a road on which the vehicle is currently running.

8. The control device of the vehicle according to claim 1 , wherein the controller is configured to provide the automatic driving control by controlling the power transmission device based on a type of a road in a route to the destination.
