Abstract

Provided is a vehicle driving support device capable of appropriately notifying an operator of a vehicle itself of other vehicles traveling in an adjacent lane. The vehicle driving support device performs driving support for the own vehicle. The vehicle driving support device obtains a distance between another vehicle and the own vehicle existing in the adjacent lane as an inter-vehicle distance based on the position information, or obtains a value obtained by dividing the inter-vehicle distance by a relative speed of the own vehicle with respect to the other vehicle as an inter-vehicle time based on the position information, and when the inter-vehicle distance is equal to or less than a predetermined distance or the inter-vehicle time is equal to or less than a predetermined time and the other vehicle is not detected by the surrounding detection device as the target condition is satisfied, performs driving support for notifying that the other vehicle exists in the adjacent lane to the operator when an intention of the operator of the own vehicle to cause the own vehicle to enter the adjacent lane or an operation by the operator to cause the own vehicle to enter the adjacent lane is detected.

  3. 3. The driving assistance device for vehicle according to claim 1, The control device is configured to perform the driving assistance in which, when the inter-vehicle distance is equal to or less than a predetermined distance and the other vehicle is not detected by the surrounding area detection device that the target condition is satisfied, the driver is notified that the other vehicle is present on the adjacent lane when an intention of the operator of the own vehicle to cause the own vehicle to enter the adjacent lane or an operation of the operator to cause the own vehicle to enter the adjacent lane is detected.
  4. 4. The vehicle driving assistance device according to any one of claims 1 to 3, The adjacent lane is a facing lane adjacent to a lane in which the own vehicle is traveling, The other vehicle is a oncoming vehicle traveling in the oncoming lane.
  5. 5. The vehicle driving assistance device according to any one of claims 1 to 3, The object condition includes a condition that an obstacle is detected by the surrounding detection device in front of the own vehicle and on a lane on which the own vehicle is traveling.
  6. 6. The vehicle driving assistance device according to any one of claims 1 to 3, The wireless communication information is information transmitted from a wireless communication terminal held by a driver sitting in the other vehicle.
  7. 7. The vehicle driving assistance device according to any one of claims 1 to 3, The control device is configured to determine that an intention of an operator of the own vehicle to enter the adjacent lane is detected when an operation of a turn signal device of the own vehicle indicating that the own vehicle is to enter the adjacent lane is detected, and determine that an operation of the operator to enter the adjacent lane is detected when a steering wheel operation of the own vehicle is detected, the steering wheel operation being performed to cause the own vehicle to enter the adjacent lane.

Description

Vehicle driving support device Technical Field The present invention relates to a vehicle driving support device. Background Patent document 1 describes a vehicle driving support device that gives an alarm to a driver of a host vehicle when another vehicle traveling in an adjacent lane exists in the vicinity of the host vehicle when a turn signal (direction indicator) is not operated (blinks). In addition, in this vehicle driving support device, when the turn signal lamp is operated, no warning is issued even if another vehicle running on an adjacent lane exists in the vicinity of the own vehicle. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2017-111732 Disclosure of Invention Sometimes, when the turn signal lamp is operated and the own vehicle is going to enter an adjacent lane, the driver of the own vehicle does not recognize that other vehicles traveling in the adjacent lane are present in the vicinity of the own vehicle. In this case, it is preferable to notify the driver of the own vehicle of the presence of such other vehicle. However, in the conventional vehicle driving support apparatus, when the turn signal is on and the own vehicle is approaching the adjacent lane, no warning is issued even if another vehicle traveling in the adjacent lane is present in the vicinity of the own vehicle. Therefore, the driver of the own vehicle will not be appropriately notified about other vehicles traveling in the adjacent lane. On the other hand, when the turn signal lamp is on and the own vehicle is about to enter an adjacent lane, the driver of the own vehicle sometimes recognizes that another vehicle traveling in the adjacent lane is present in the vicinity of the own vehicle. In this case, if the driver of the own vehicle is notified of the presence of such other vehicle, the driver may feel tired. In this case, it cannot be counted as an appropriate notification to the driver of the own vehicle regarding other vehicles traveling in the adjacent lane. In addition, even if the driver of the own vehicle does not recognize the presence of another vehicle traveling in the adjacent lane, it is possible that the driver recognizes the presence of the other vehicle when the own vehicle enters the adjacent lane, and there is a sufficient time to avoid the contact of the other vehicle with the own vehicle. In this case, if the driver of the own vehicle is notified of the presence of the other vehicle, the driver may feel tired. In this case, too, it cannot be counted that the driver of the own vehicle is appropriately notified of other vehicles traveling in the adjacent lane. The purpose of the present invention is to provide a vehicle driving support device that can appropriately notify an operator of a host vehicle of other vehicles traveling in adjacent lanes. One of the vehicle driving support devices according to the present invention includes a control device that performs driving support for the own vehicle based on position information of the other vehicle included in wireless communication information transmitted (transferred) from the other vehicle. The control device is configured to acquire a distance between the other vehicle and the own vehicle existing in an adjacent lane adjacent to the lane on which the own vehicle is traveling as a vehicle-to-vehicle distance based on the position information, or acquire the vehicle-to-vehicle distance based on the position information and acquire a value obtained by dividing the vehicle-to-vehicle distance by a relative speed of the own vehicle with respect to the other vehicle as a vehicle-to-vehicle time. Further, the control device is configured to, when the inter-vehicle distance is equal to or less than a predetermined distance or the inter-vehicle time is equal to or less than a predetermined time and the other vehicle is not detected as being satisfied by the surrounding detection device mounted on the own vehicle, perform the driving assistance for notifying the operator that the other vehicle is present on the adjacent lane when the intention of the operator of the own vehicle to cause the own vehicle to enter the adjacent lane or the operation of the operator for causing the own vehicle to enter the adjacent lane is detected. In particular, the control device is configured to perform the driving assistance in which, when the vehicle-to-vehicle time is equal to or less than a predetermined time and the other vehicle is not detected by the surrounding area detection device that the target condition is satisfied, the driver is notified that the other vehicle is present in the adjacent lane when an intention of the operator of the own vehicle to cause the own vehicle to enter the adjacent lane or an operation of the operator for causing the own vehicle to enter the adjacent lane is detected. According to the present invention, in the case where the vehicle-to-vehicle time is longer than the predetermined tim
