Autonomous driving control device

Abstract

An autonomous driving control device is capable of starting an autonomous driving control without an operation of a driver and reducing a possibility that the driver can not start manual driving. An autonomous driving control is switched to manual driving when a determination section determines that the amount of operation by the driver is equal to or greater than a first threshold, before a predetermined time elapses since the autonomous driving control is automatically started. An autonomous driving control is switched to a manual driving when the determination section determines that the amount of operation by the driver is equal to or greater than a second threshold that is greater than the first threshold, after the predetermined time elapses.

What is claimed: 
     
         1 . An autonomous driving control device that performs an autonomous driving control of a vehicle, said autonomous driving control device is configured to perform:
 detecting an override operation by a driver during execution of the autonomous driving control for automatically controlling at least one of driving operations including acceleration, deceleration, and steering of the vehicle; and   terminating the autonomous driving control when the override operation satisfies a predetermined override condition, wherein
 said predetermined override condition changes from a condition in which the autonomous driving is easily terminated to a condition in which the autonomous driving is difficult to be terminated. 
   
     
     
         2 . The autonomous driving control device according to  claim 1 , further being configured to notify the driver of the start of the autonomous driving control. 
     
     
         3 . The autonomous driving control device according to  claim 1 , further being configured to perform:
 utilizing a monitor device that monitors a state of the driver; and   changing the timing when the override condition changes based on the state of the driver monitored by the monitor device.   
     
     
         4 . The autonomous driving control device according to  claim 1 , further being configured to notify the driver that the override condition is likely to be satisfied before the override condition is changed, and that the override condition is unlikely to be satisfied after the override condition is changed.
