KR-20260067996-A - VEHICLE DRIVING ASSISTANCE APPARATUS

Abstract

A vehicle driving assistance device is provided that can provide appropriate notification to the operator of the vehicle regarding other vehicles traveling in adjacent lanes. The vehicle driving support device (10) provides driving support for the vehicle (100) based on location information of other vehicles included in wireless communication information transmitted from other vehicles (402, 403). The vehicle driving support device obtains the distance between the vehicle and other vehicles existing in adjacent lanes as the distance between vehicles based on location information, and obtains the value obtained by dividing the distance between vehicles by the relative speed of the vehicle to other vehicles as the time between vehicles based on location information. When the target condition is established that the time between vehicles is less than or equal to a predetermined time and other vehicles are not detected by the surrounding detection device (50) mounted on the vehicle, the vehicle driving support device notifies the operator that there is another vehicle in the adjacent lane when the operator of the vehicle detects an intention to enter the vehicle into the adjacent lane or an operation by the operator to enter the vehicle into the adjacent lane.

4. In paragraph 1 or 2, A vehicle driving assistance device, wherein the above target condition includes the condition that an obstacle is detected by the surrounding detection device in front of the vehicle and in the lane in which the vehicle is traveling.
5. In paragraph 1 or 2, A vehicle driving assistance device in which wireless communication information is information transmitted from a wireless communication terminal possessed by a driver riding in the aforementioned vehicle.
6. In paragraph 1 or 2, A vehicle driving support device configured such that, when the control device detects the operation of the turn signal device of the vehicle indicating that the vehicle is entering the adjacent lane, it determines that the operator of the vehicle has detected an intention to enter the vehicle into the adjacent lane, and when the control device detects the steering operation of the vehicle to enter the adjacent lane, it determines that the operation by the operator to enter the vehicle into the adjacent lane has been detected.

Description

Vehicle Driving Assistance Apparatus The present invention relates to a vehicle driving assistance device. Patent Document 1 describes a vehicle driving assistance device configured to issue an alarm to the driver of a vehicle when another vehicle traveling in an adjacent lane is present near the vehicle when the turn signal is not activated. In addition, in this vehicle driving assistance device, when the turn signal is activated, the alarm is not issued even if another vehicle traveling in an adjacent lane is present near the vehicle. When a turn signal is activated and a vehicle is attempting to enter an adjacent lane, the driver may not be aware that another vehicle traveling in that adjacent lane is present near the vehicle. In such cases, it is desirable to notify the driver of the vehicle of the presence of such another vehicle. However, in conventional vehicle assistance systems, when a turn signal is activated and the vehicle is attempting to enter an adjacent lane, no warning is issued even if another vehicle traveling in the adjacent lane is present near the vehicle. Consequently, the driver of the vehicle is not properly notified of the other vehicle traveling in the adjacent lane. Meanwhile, when the turn signal is activated and the vehicle is attempting to enter an adjacent lane, the driver of the vehicle may be aware that another vehicle traveling in the adjacent lane is present near the vehicle. In such cases, notifying the driver of the vehicle of the presence of such another vehicle may cause inconvenience to the driver. In this case, it is not considered that proper notification to the other vehicle traveling in the adjacent lane has been made to the driver of the vehicle. In addition, even if the driver of the vehicle is not aware of the presence of another vehicle traveling in an adjacent lane, there may be a time window when the driver becomes aware of the other vehicle upon entering the adjacent lane and avoids contact between the vehicle and the other vehicle. In such cases, notifying the driver of the vehicle of the presence of the other vehicle may cause inconvenience to the driver. Even in this case, it does not constitute that proper notification regarding the other vehicle traveling in the adjacent lane has been made to the driver of the vehicle. The objective of the present invention is to provide a vehicle driving assistance device capable of providing appropriate notification to the operator of a vehicle regarding other vehicles traveling in adjacent lanes. One of the vehicle driving support devices according to the present invention comprises a control device that performs driving support for a self-vehicle based on location information of the other vehicle included in wireless communication information transmitted from the other vehicle. The control device is configured to acquire the distance between the other vehicle and the self-vehicle existing in an adjacent lane adjacent to the lane in which the self-vehicle is driving as the inter-vehicle distance based on the location information, and to acquire the value obtained by dividing the inter-vehicle distance by the relative speed of the self-vehicle with respect to the other vehicle as the inter-vehicle time based on the location information. Furthermore, the control device is configured to perform driving support by notifying the operator that the other vehicle exists in the adjacent lane when a target condition is met, such that the inter-vehicle time is less than or equal to a predetermined time and the other vehicle is not detected by a surrounding detection device mounted on the self-vehicle, and when the intention of the operator of the self-vehicle to enter the self-vehicle into the adjacent lane or an operation by the operator to enter the self-vehicle into the adjacent lane is detected. According to the present invention, if the time between vehicles is longer than a predetermined time, notification is not provided even if the operator of the vehicle intends to move the vehicle into an adjacent lane. That is, even if the operator of the vehicle has moved the vehicle into an adjacent lane, notification is not provided if there is sufficient time for the operator of the vehicle to avoid contact between the vehicle and other vehicles. Furthermore, if other vehicles are detected by surrounding detection devices and there is a high probability that the operator of the vehicle is aware of the presence of other vehicles, notification is not provided even if the operator of the vehicle intends to move the vehicle into an adjacent lane. Thus, notification is not provided when there is sufficient time for the operator of the vehicle to avoid contact between the vehicle and other vehicles, or when the operator of the vehicle is aware of the presence of other vehicles. Therefore, the implementation of unnecessary notifications can be suppressed, and as a result, the inconvenience caused to the operator of the vehicle can be
