Abstract: An automatic driving control device changes the degree of automation during an automatic control or the degree of change to the vehicle behavior during the automatic control, on the basis of the peripheral monitoring state of a driver, and on the basis of how easy it is to perform a switching operation for prioritizing manual control over automatic control. Thus, the automatic driving control device makes it possible to ensure the convenience of automatic control, by dynamically changing the degree of automation or the degree of change to the vehicle behavior, without uniformly stopping automatic control of steering and acceleration.

Abstract: Provided is a drive assistance device for a self-driving car with which drive assistance is less liable to be deactivated, even if an abnormality of a monitoring device for monitoring a state of a driver occurs. A device checking ECU checks whether a plurality of monitoring devices for monitoring the state of the driver are normal or abnormal. On the basis of the check result, an assistance degree determination unit (function availability determination unit) determines a use degree (availability) of a plurality of drive assistance functions (ACC function, LKAS function, and ALC function) including an ACC function. Drive assistance effected by a vehicle with respect to the driver is therefore less liable to be deactivated.

Abstract: A drive assist controller verifies the driving intention of a driver on the basis of whether or not the driver is contacting the steering wheel when a lane-maintaining control is being executed.

This configuration makes it possible to appropriately determine the driving intention of a driver, by changing the method of verifying the driving intention of the driver between cases when the driver has driving authority and cases when the vehicle has driving authority.

Abstract: Provided is a driving assistance device such that even if the main power supply voltage of a main electricity storage device becomes less than or equal to the operable voltage of a device for monitoring the state of a driver, interruptions in driving assistance are prevented. While a voltage reduction state in which the main power supply voltage of the main electricity storage device is equal to or less than the operable voltage of the driver state monitoring device is continuing, the state of the driver is monitored by a device (steering torque sensor) that operates with the auxiliary power supply voltage of an auxiliary electricity storage device, such as a capacitor. Thus, it is possible to monitor whether or not the driver is a so-called Driver in the Loop and continue driving assistance even while the voltage reduction state of the main power supply voltage is continuing.
