Automated driving system, portable device and travel control device
The automated driving system automatically drives a vehicle by cooperative operation of a travel control device controlling travel of the vehicle and a portable device possessed by a driver of the vehicle. In the cooperative operation, the portable device transmits route data to the travel control device; the travel control device sets an event location on the route, based on the route data, controls travel of the vehicle in an automated-driving control area, based on the route data and circumstance data, and transmits notification data for notifying the driver of a change of a travel condition to the portable device; and the portable device notifies the driver of the change, based on the notification data. Upon receiving an operational input to stop the cooperative operation, the portable device notifies the driver of a warning message or ignores the received operational input if the event location is set in the area.
1. An automated driving system comprising:
a travel control device controlling travel of a vehicle; and
a portable device possessed by a driver of the vehicle,
the automated driving system automatically driving the vehicle by cooperative operation of the travel control device and the portable device,
wherein in the cooperative operation,
the portable device transmits route data indicating a route from a starting point to a destination to the travel control device,
the travel control device
sets an event location on the route, based on the route data, the event location being a location where a travel condition of the vehicle is changed,
controls travel of the vehicle in an automated-driving control area of the route from the present position of the vehicle to a position at a predetermined distance ahead thereof, based on the route data and circumstance data indicating circumstances around the vehicle, the circumstance data being acquired by a circumstance sensor, and
transmits notification data for notifying the driver of a change of the travel condition to the portable device, and
the portable device notifies the driver of the change of the travel condition, based on the notification data, and
wherein upon receiving an operational input to stop the cooperative operation, the portable device notifies the driver of a warning message or ignores the received operational input if the event location is set in the automated-driving control area,
while the portable device stops the cooperative operation if the event location is not set in the automated-driving control area.
2. The automated driving system according to claim 1 , wherein
the warning message is a message asking for consent of the driver to stop the cooperative operation, and
the portable device stops the cooperative operation if the consent of the driver is confirmed.
3. A portable device for automatically driving a vehicle by cooperative operation with a travel control device controlling travel of the vehicle, the portable device comprising a processor configured to:
transmit, in the cooperative operation, route data indicating a route from a starting point to a destination to the travel control device,
notify, in the cooperative operation, a driver of the vehicle that a travel condition of the vehicle is changed, based on notification data received from the travel control device,
acquire, in the cooperative operation, data indicating an event location from the travel control device, the event location being a location where a travel condition of the vehicle is changed and being set based on the route data, and
upon receiving an operational input to stop the cooperative operation, notify the driver of a warning message or ignores the received operational input if the event location is set in an area of the route from the present position of the vehicle to a position at a predetermined distance ahead thereof,
stops cooperative operation if the event location is not set in an area of the route from the present position of the vehicle to a position at a predetermined distance ahead thereof.
4. An automated driving system comprising:
a travel control device controlling travel of a vehicle; and
a portable device possessed by a driver of the vehicle,
the automated driving system automatically driving the vehicle by cooperative operation of the travel control device and the portable device,
wherein in the cooperative operation,
the portable device transmits route data indicating a route from a starting point to a destination to the travel control device,
the travel control device
sets an event location on the route, based on the route data, the event location being a location where a travel condition of the vehicle is changed,
controls travel of the vehicle in an automated-driving control area of the route from the present position of the vehicle to a position at a predetermined distance ahead thereof, based on the route data and circumstance data indicating circumstances around the vehicle, the circumstance data being acquired by a circumstance sensor, and
transmits notification data for notifying the driver of a change of the travel condition to the portable device, and
the portable device notifies the driver of the change of the travel condition, based on the notification data, and
wherein the travel control device requests the portable device to start the cooperative operation if the event location is set in the automated-driving control area and if the cooperative operation is not performed.
5. The automated driving system according to claim 4 , wherein
the travel control device transmits an event ending notice to the portable device when the travel control device requests the portable device to start the cooperative operation and the change of the travel condition of the vehicle at the event location is finished, and
upon receiving the event ending notice, the portable device returns to the state prior to the start of the cooperative operation.
6. A travel control device for automatically driving a vehicle by cooperative operation with a portable device possessed by a driver of the vehicle, the travel control device comprising a processor configured to:
receive, in the cooperative operation, route data indicating a route from a starting point to a destination from the portable device and sets an event location on the route, based on the received route data, the event location being a location where a travel condition of the vehicle is changed,
control, in the cooperative operation, travel of the vehicle in an automated-driving control area of the route from the present position of the vehicle to a position at a predetermined distance ahead thereof, based on the route data and circumstance data indicating circumstances around the vehicle, the circumstance data being acquired by a circumstance sensor,
transmit, in the cooperative operation, notification data for notifying the driver of a change of the travel condition to the portable device, and
request the portable device to perform the cooperative operation if the event location is set in the automated-driving control area and if the cooperative operation is not performed.
