1. A presentation control device configured to control information presentation to a driver of a vehicle capable of performing automated driving, the presentation control device comprising:
at least one processor; and
a memory connected to the at least one processor and storing instructions that, when executed by the at least one processor, configure the at least one processor to provide:
a determination unit configured to distinguish
between a monitoring interruption mode in which the driver is permitted to interrupt surroundings monitoring and a monitoring-required mode in which the driver is prohibited to interrupt the surroundings monitoring, and
in the monitoring-required mode, between a hands-free permitted state in which the driver is permitted to release hands from a steering wheel and a hands-free prohibited state in which the driver is prohibited to release the hands from the steering wheel;
a presentation control unit configured to perform the information presentation related to a mode transition from the monitoring interruption mode to the monitoring-required mode when the mode transition occurs, wherein
the presentation control unit is configured to perform the information presentation at an earlier timing when the monitoring interruption mode is transitioned to the hands-free prohibited state of the monitoring-required mode than when the monitoring interruption mode is transitioned to the hands-free permitted state of the monitoring-required mode.
 
11. An automated driving control system configured to control automated driving of a vehicle, the automated driving control system comprising:
at least one processor; and
a memory connected to the at least one processor and storing instructions that, when executed by the at least one processor, configure the at least one processor to provide:
a determination unit configured to distinguish
between a monitoring interruption mode in which the driver is permitted to interrupt surroundings monitoring and a monitoring-required mode in which the driver is prohibited to interrupt the surroundings monitoring, and
in the monitoring-required mode, between a hands-free permitted state in which the driver is permitted to release hands from a steering wheel and a hands-free prohibited state in which the driver is prohibited to release the hands from the steering wheel;
a presentation control unit configured to perform the information presentation related to a mode transition from the monitoring interruption mode to the monitoring-required mode when the mode transition occurs; and
a speed control unit configured to control a traveling speed of the vehicle to be lower when the monitoring interruption mode is transitioned to the hands-free prohibited state of the monitoring-required mode than when the monitoring interruption mode is transitioned to the hands-free permitted state of the monitoring-required mode.
 
12. A presentation control device configured to control information presentation to a driver of a vehicle capable of performing automated driving, the presentation control device comprising:
at least one processor; and
a memory connected to the at least one processor and storing instructions that, when executed by the at least one processor, configure the at least one processor to provide:
a determination unit configured to distinguish between a monitoring-required mode in which the driver is prohibited to interrupt surroundings monitoring during the automated driving, and in the monitoring-required mode, between a hands-free permitted state in which the driver is permitted to release hands from a steering wheel and a hands-free prohibited state in which the driver is prohibited to release the hands from the steering wheel;
a presentation control unit configured to perform the information presentation related to a state transition in the monitoring-required mode when the state transition occurs;
wherein
the determination unit is further configured to determine whether a securing condition is satisfied, the securing condition being satisfied when it is necessary to secure an operation time for operating the steering wheel as a preparation time for driving in the hands-free permitted state before the hands-free prohibited state is transitioned to the hands-free permitted state; and
the presentation control unit is configured to perform a state transition presentation that is the information presentation related to the state transition when the state transition from the hands-free prohibited state to the hands-free permitted state occurs, and to perform the state transition presentation at a later timing when the securing condition is satisfied than when the securing condition is not satisfied.
 
13. A presentation control device configured to control information presentation to a driver of a vehicle capable of performing automated driving, the presentation control device comprising:
at least one processor; and
a memory connected to the at least one processor and storing instructions that, when executed by the at least one processor, configure the at least one processor to provide:
a determination unit configured to distinguish between a monitoring interruption mode in which the driver is permitted to interrupt surroundings monitoring during the automated driving, a monitoring-required mode in which the driver is prohibited to interrupt the surroundings monitoring, and in the monitoring-required mode, between a hands-free permitted state in which the driver is permitted to release hands from a steering wheel and a hands-free prohibited state in which the driver is prohibited to release the hands from the steering wheel;
a presentation control unit configured to perform the information presentation related to a mode transition from the monitoring interruption mode to the monitoring-required mode when the mode transition occurs;
wherein
the determination unit is further configured to determine whether a securing condition is satisfied, the securing condition being satisfied when it is necessary to secure an operation time for operating the steering wheel as a preparation time for driving in the hands-free permitted state before the hands-free prohibited state is transitioned to the monitoring interruption mode; and
the presentation control unit is configured to perform a state transition presentation that is the information presentation related to the state transition when the state transition from the hands-free prohibited state to the monitoring interruption mode occurs, and to perform the state transition presentation at a later timing when the securing condition is satisfied than when the securing condition is not satisfied.
