AI Technical Summary
Technical Problem
Existing vehicle driving support systems incur high communication costs and loads due to constant wireless communication of location information, which can lead to inefficient notification timing for potential collisions at intersections.
Method used
A vehicle driving support system that transmits determination information only when a mobile vehicle passes a predetermined point near an intersection, using a server to manage communication and notify the vehicle of approaching objects based on specific conditions, including speed and time, to optimize communication and notification timing.
Benefits of technology
Reduces communication costs and load while ensuring timely and appropriate notification of approaching objects, allowing for effective collision avoidance measures.

Abstract
To provide a vehicle driving assistance system with low communication costs and low communication load. [Solution] The vehicle driving support system 10 includes a vehicle driving support device 200 mounted on the vehicle 400 and a server 100 located on a communication network 150. The server receives location information wirelessly transmitted from a wireless communication terminal 300 held by the mobile body 350 via the communication network, and when it determines that the mobile body has passed a predetermined point toward a predetermined intersection based on the location information, it transmits determination information to the vehicle driving support device via the communication network. When the notification conditions are met, such as the predetermined intersection being a target intersection and the predetermined intersecting road being a target intersecting road, the vehicle driving support device makes a notification in a first notification form to inform the operator of the vehicle of the presence of the mobile body, and when the vehicle's onboard equipment 240 directly detects the mobile body while the notification is being made in the first notification form, it makes a notification in a second notification form.
