Abstract

A vehicle control apparatus is capable of switching between an automatic driving control mode and a manual driving mode. The apparatus includes a driver state monitor and a vehicle controller. The driver state monitor monitors a gaze of a driver and a state of the driver. The vehicle controller controls steering and a drive system in the automatic driving control mode. In a case that the driver state monitor detects that the driver gazes at a device that is operated by the driver as a second task when the vehicle controller requests to the driver for a takeover from the automatic driving control mode to the manual driving mode, the vehicle controller stops a function of the device.

Claims (37)

1. A vehicle control apparatus that switches a driving mode of a vehicle between an automatic driving control mode and a manual driving mode, the vehicle control apparatus comprising:

a driver state monitor configured to monitor a gaze of a driver of the vehicle and a state of the driver of the vehicle; and

a vehicle controller configured to control steering and a drive system of the vehicle while the vehicle is in the automatic driving control mode,

wherein while the vehicle is in the automatic driving control mode, the vehicle controller requests the driver for a takeover from the automatic driving control mode to the manual driving mode,

wherein upon requesting the takeover from the automatic driving control mode to the manual driving mode and prior to completing the takeover from the automatic driving control mode to the manual driving mode, the vehicle controller i) determines that the driver state monitor detects the driver gazing at a device that is being operated by the driver and ii) performs a function stop to stop a function of the device,

wherein upon performing the function stop and stopping the function of the device being operated by the driver, the vehicle controller switches the driving mode of the vehicle from the automatic driving control mode to the manual driving mode,

wherein the vehicle control apparatus further comprises a manual driving takeover judgement unit configured to determine a completion of the takeover from the automatic driving control mode to the manual driving mode, and

wherein in response to determining the completion of the takeover from the automatic driving control mode to the manual driving mode, the vehicle controller cancels the function stop such that the stopping of the function of the device is cancelled.

2. The vehicle control apparatus according to claim 1 , wherein the manual driving takeover judgment unit determines that the takeover from the automatic driving control mode to the manual driving mode has completed based on determining that the driver has steered a steering wheel of the vehicle.

3. The vehicle control apparatus according to claim 1 , wherein

the device is a wireless communication device, and

the vehicle control apparatus further comprises a transceiver configured to transmit a wireless control signal with which the vehicle controller remotely controls the wireless communication device.

4. The vehicle control apparatus according to claim 2 , wherein

the device is a wireless communication device, and

the vehicle control apparatus further comprises a transceiver configured to transmit a wireless control signal with which the vehicle controller remotely controls the wireless communication device.

5. A vehicle control apparatus that switches a driving mode of a vehicle between an automatic driving control mode and a manual driving mode, the vehicle control apparatus comprising circuitry configured to

monitor a gaze of a driver of the vehicle and a state of the driver of the vehicle; and

control steering and a drive system of the vehicle while the vehicle is in the automatic driving control mode,

wherein while the vehicle is in the automatic driving control mode, the circuitry requests the driver for a takeover from the automatic driving control mode to the manual driving mode,

wherein upon requesting the takeover from the automatic driving control mode to the manual driving mode and prior to completing the takeover from the automatic driving control mode to the manual driving mode, the circuitry i) determines that the driver gazes at a device that is being operated by the driver, and ii) performs a function stop to stop a function of the device,

wherein upon performing the function stop and stopping the function of the device being operated by the driver, the circuitry switches the driving mode of the vehicle from the automatic driving control mode to the manual driving mode, and

wherein in response to the circuitry determining a completion of the takeover from the automatic driving control mode to the manual driving mode, the circuitry cancels the function stop such that the stopping of the function of the device is cancelled.

6. The vehicle control apparatus according to claim 5 , wherein the circuitry determines that the takeover from the automatic driving control mode to the manual driving mode has completed based on determining that the driver has steered a steering wheel of the vehicle.

7. A vehicle control apparatus that switches a driving mode of a vehicle between an automatic driving control mode and a manual driving mode, the vehicle control apparatus comprising:

a transceiver configured to transmit and receive information to and from a wireless communication device; and

circuitry configured to:

monitor a gaze of a driver of the vehicle; and

control steering and a drive system of the vehicle while the vehicle is in the automatic driving control mode;

notify the driver of switching of the driving mode to the manual driving mode from the automatic driving control mode while the vehicle is in the automatic driving control mode;

perform a first determination to determine whether the driver gazes forward after notifying the switching;

in response to determining in the first determination that the driver gazes forward, perform the switching;

in response to determining in the first determination that the driver does not gaze forward, perform a second determination to determine whether the driver gazes at the wireless communication device;

in response to determining in the second determination that the driver gazes at the wireless communication device, transmit a first control information via the transceiver to the wireless communication device, the first control information including a command to the wireless communication device to stop a function of the wireless communication device;

perform a third determination to determine whether the driver gazes forward after transmitting the first control information;

in response to determining in the third determination that the driver gazes forward, i) perform the switching and ii) transmit a second control information via the transceiver to the wireless communication device based on a completion of a takeover from the automatic driving control mode to the manual driving mode, the second control information including a command to the wireless communication device to restart the function of the wireless communication device;

in response to determining in the third determination that the driver does not gaze forward, i) abort the switching and ii) transmit a third control information via the transceiver to the wireless communication device, the third control information including a command to the wireless communication device to output an alarm; and

in response to determining in the second determination that the driver does not gaze at the wireless communication device, i) abort the switching and ii) transmit the third control information via the transceiver to the wireless communication device.
