A system designed such that a following vehicle performs following travel to follow a leading vehicle is provided. A departure point and a destination point desired by a user of the following vehicle is obtained. Search for the leading vehicle to be followed by the following vehicle is performed based on the departure point and the destination point. A travel plan including a section of the following travel as at least a part of travel between the departure point and the destination point is generated. Information representing the section of the following travel to a user of the leading vehicle is transmitted.

A computer-implemented method for determining an estimate of the capability of a vehicle driver to take over control of a vehicle, wherein the method comprises: determining at least one estimation parameter, the at least one estimation parameter representing an influencing factor for the capability of the vehicle driver to take over control of the vehicle; and determining an estimate on the basis of the at least one estimation parameter by means of a predefined estimation rule, the estimate representing the capability of the vehicle driver to take over control of the vehicle.

A vehicle guidance system detects when a driver of the vehicle manually intervenes in the longitudinal and/or transverse guidance of the vehicle while the vehicle is being operated in an automated driving mode. The vehicle guidance system outputs an indication to the driver via a user interface of the vehicle prompting the driver to take over the longitudinal and/or transverse guidance of the vehicle. The vehicle guidance system also continues to provide the longitudinal and/or lateral guidance of the vehicle in at least a partially automated manner for a takeover period of time and/or for a takeover distance.

A method and a system analyze the control of a vehicle having an autonomous driving unit. A change in the driving mode from autonomous driving to manual driving is detected, and at least one driving parameter before and/or after detecting the change is monitored. Based on driving values obtained by the monitoring with respect to the detected change in driving mode, at least one driving quantity quantifying the quality of interplay between the autonomous driving unit and a human driver is determined.

A driving handover control device includes a memory and a processor coupled to the memory. In a case in which driving is handed over from a first state in which a vehicle is traveling by remote driving by a first driver from outside the vehicle or by occupant driving by the first driver in the vehicle, to a second state in which the vehicle travels by the remote driving or the occupant driving by a second driver who is different from the first driver, the processor is configured to cause transition from the first state to a third state in which the vehicle is caused to travel by automatic driving, and then cause transition from the third state to the second state.

A driving handover control device includes a memory and a processor coupled to the memory. In a case in which driving is handed over from a first state in which a vehicle travels in accordance with instruction from a remote operator of the vehicle to a second state in which the vehicle travels in accordance with operation by a passenger of the vehicle, the processor implements a transition from the first state to a third state in which the vehicle travels autonomously without instruction from the remote operator or operation by the passenger, and, after the transition from the first state to the third state, implements a transition from the third state to the second state.

To implement a configuration to calculate a manual driving recoverable time required for a driver who is executing automatic driving in order to achieve a requested recovery ratio (RRR) for each road section, and issue a manual driving recovery request notification on the basis of the calculated time. A data processing unit is included, which calculates a manual driving recoverable time required for a driver who is executing automatic driving in order to achieve a predefined requested recovery ratio (RRR) from automatic driving to manual driving and determines notification timing of a manual driving recovery request notification on the basis of the calculated time. The data processing unit acquires the requested recovery ratio (RRR) for each road section set as ancillary information of a local dynamic map (LDM), and calculates the manual driving recoverable time for each road section scheduled to travel, using learning data for each driver.

A notification device includes: an information acquisition unit that acquires driving operation information indicating a driving operation status by a driver of a vehicle; and a notification unit that notifies the driver of a driving operation requested to be executed by the driver during a period from notification of transfer of driving authority from the vehicle to the driver to transfer of the driving authority to the driver. The notification unit notifies the driver of a driving operation, execution of which has not been completed by the driver among the driving operations requested to be executed by the driver on the basis of the driving operation information.

A vehicle control apparatus includes one or more processors. The one or more processors execute determination as to whether a driving state of the vehicle involves difficulty in continuing the automatic driving. In a case where the driving state is determined as involving difficulty in continuing the automatic driving, the one or more processors execute determination on a difficulty level of operation authority transfer from the automatic driving to the manual driving on the basis of information regarding a surrounding environment of the vehicle, information regarding a driving skill of a driver, and information regarding an experience level of the driver of the operation authority transfer. The one or more processors execute setting of a driving-state condition for executing the operation authority transfer in accordance with the difficulty level. The one or more processors execute the operation authority transfer in a case where the driving-state condition is satisfied.

An HMI control device includes an automation level acquisition portion and a display control unit. The automation level acquisition portion acquires an autonomous driving level determined by a driving control device. The display control portion controls an image display operation of an HMI device according to the autonomous driving level acquired by the automation level acquisition portion. When terminating a high autonomous driving level as the autonomous driving level, the display control portion controls the HMI device to provide an action instruction display that instructs the driver to take a low-level associated state so as to handle a low autonomous driving level. The low autonomous driving level is the autonomous driving level under which an in-vehicle system including the driving control device is prohibited from performing at least one of a lateral motion control realized by performing steering and a longitudinal motion control realized by performing acceleration/deceleration.
