Abstract

The present invention addresses the problem of performing automatic driving in accordance with driving characteristics of a driver while considering a vehicle peripheral state, even in the case where the vehicle peripheral state during manual driving is different from the vehicle peripheral state during the automatic driving. The present invention is a vehicle control device 120 that can switch between manual driving in which a vehicle is caused to travel by the operation of a driver and automatic driving in which the vehicle is caused to travel automatically in accordance with a traveling plan. The vehicle control device 120 is provided with a vehicle control planning unit 123 that devises the traveling plan, and a verification unit 124 that verifies a vehicle traveling state on the basis of the traveling plan. The vehicle control device 120 devises the traveling plan in accordance with learning related to driving characteristics of the driver during the manual driving, and the result of learning related to the verification result from the verification unit 124.

Claims (18)

1. A vehicle control device capable of switching between manual driving in which a vehicle travels according to an operation of a driver and automatic driving in which the vehicle automatically travels according to a traveling plan, the device comprising:

a vehicle controller configured to

plan the traveling plan; and

verify a traveling state of the vehicle based on the traveling plan,

wherein the traveling plan is planned according to learning related to driving characteristics of the driver during the manual driving and a result of learning related to a verification result of the controller, and the controller implements the traveling plan to set a route of the vehicle,

wherein the controller has a plurality of preset alarm items, and simultaneously selects corresponding alarm items among the alarm items according to an event when the event is detected as a result of verifying the traveling state of the vehicle based on the traveling plan, and

the traveling plan is planned based on learning corresponding to the selected alarm item and the learned result.

2. The vehicle control device according to claim 1 , wherein the controller is further configured to

perform the learning related to the verification result of the controller and the learning of the driving characteristics of the driver during the manual driving,

wherein the controller plans the traveling plan based on a learning result.

3. The vehicle control device according to claim 1 ,

wherein the learning related to the driving characteristics of the driver during the manual driving is to learn driving characteristics and priorities for a plurality of preset driving characteristic items, and

the learning related to the verification result of the controller is to preferentially learn a driving characteristic item with a low priority.

4. The vehicle control device according to claim 1 ,

wherein the controller selects a rule-based traveling plan retained in advance when a dangerous event is detected as a result of verifying the traveling state of the vehicle based on the traveling plan, and

the learning related to the verification result of the controller is to learn according to driving characteristics of the rule-based traveling plan.

5. The vehicle control device according to claim 1 , wherein the preset alarm items include an alarm when a distance between a host vehicle and a merging terminal end is predicted to be less than a remaining distance.

6. The vehicle control device according to claim 1 , wherein a plurality of driving characteristic items of the driver obtained during manual driving may be simultaneously changed to reduce incompatibility.
