Station and in-vehicle device
A server station receives situation information and vehicle information respectively from three vehicles. The server station calculates how to pass by an on-coming vehicle for each of the three vehicles, and sends to each of the three vehicles a wait instruction of where to wait for and pass by the on-coming vehicle or a notification instruction of the on-coming vehicle when there is no place to wait. For example, the server station sends, to a first vehicle, the notification instruction due to having no place to wait, sends, to a second vehicle, a wait instruction to wait at a current position, which is a pass-by place, until the on-coming vehicle passes, and sends, to a third vehicle, a wait instruction to wait in a pass-by place, which is available to the third vehicle.
1. An in-vehicle device disposed on a subject vehicle, the in-vehicle device comprising:
a memory,
a control device coupled to the memory and configured to:
(i) obtain subject vehicle situation information and subject vehicle non-situation information, wherein the subject vehicle situation information includes a subject vehicle position and a subject vehicle speed, and wherein the subject vehicle non-situation information is associated with a subject vehicle size;
(ii) store, in the memory, the subject vehicle situation information and the subject vehicle non-situation information;
(iii) obtain, using wireless vehicle-to-vehicle communication, target vehicle situation information and target vehicle non-situation information on a target vehicle;
(iv) determine whether the subject vehicle will encounter the target vehicle in a hard-to-pass place; and
(v) in response to determining that the subject vehicle will encounter the target vehicle in the hard-to-pass place,
detect an other vehicle that uses a pass-by place positioned on a road ahead of the subject vehicle and before a predicted encounter position with the target vehicle based on the subject vehicle situation information,
based on detecting the other vehicle, determine an availability of the pass-by place, and
transmit an instruction to a notifier to notify a driver of the subject vehicle with a display or a sound.
2. The in-vehicle device of claim 1 , wherein the control device is further configured to:
upon a determination that the pass-by place is ahead, determine whether there is any passable place available;
upon a determination that passable place is available, notify the driver of the subject vehicle to wait at a farthest ahead available passable place.
3. The in-vehicle device of claim 1 , wherein the control device is further configured to:
upon a determination that the pass-by place is ahead, determine whether there is any passable place available;
upon a determination that a passable place is not available, determine whether a current position is a pass-by place;
upon a determination that the current position is a pass-by place, notify the driver to wait at the current position.
4. The in-vehicle device of claim 1 , wherein the control device is further configured to:
upon a determination that the pass-by place is ahead, determine whether there is any passable place available;
upon a determination that a passable place is not available, determine whether a current position is a pass-by place;
upon a determination that the current position is not a pass-by place, notify the driver of an on-coming vehicle.
5. The in-vehicle device of claim 1 , wherein the control device is further configured to:
upon a determination that the pass-by place is not ahead, determine whether a current position is a pass-by place;
upon a determination that the current position is a pass-by place, notify the driver to wait at the current position.
6. The in-vehicle device of claim 1 , wherein the control device is further configured to:
upon a determination that the pass-by place is not ahead, determine whether a current position is a pass-by place;
upon a determination that the current position is not a pass-by place, notify the driver of an on-coming vehicle.
7. The in-vehicle device of claim 1 , wherein the control device is further configured to:
cause the notifier to notify the driver that the subject vehicle is waiting at the passable place.
8. The in-vehicle device of claim 1 , wherein the control device is further configured to:
detect, as the other vehicle that uses the pass-by place, a vehicle currently waiting in the pass-by place and a vehicle that will possibly be waiting in the pass-by place in the future, and
determine that the pass-by place is available when there is no vehicle that uses the pass-by place.
9. The in-vehicle device of claim 1 , wherein the control device is further configured to determine whether the pass-by place is available based on a number of vehicles that can wait in the pass-by place and a number of vehicles actually using the pass-by place.
10. The in-vehicle device of claim 8 , wherein the control device is further configured to detect, as the vehicle that will possibly be waiting in the pass-by place, a vehicle that leads the target vehicle and is located at a position before the pass-by place.
11. The in-vehicle device of claim 1 , wherein the target vehicle is different from the other vehicle.
