Bumping prevention system

摘要

With the bumping prevention system according to the present invention, when a vehicle (7) passes by a fixed point information detection support facility (1) and enters the service area (24), the vehicle's driver recognizes availability of the service for provision of information, alarms, and controls for prevention of bumping when entering a crossing upon reception of a signal indicating the service area (24), and starts computing a current position of the vehicle by grasping the current running position of the vehicle and a distance up to a priority road. On the other hand, the system control system acquires information concerning vehicles (25) on the priority road from the on-road infrastructure, and provides the driver, when there is any vehicle (25) entering the crossing on the priority road, with the information concerning the crossing as well as the vehicle (25) entering the crossing at a point where the driver can brake the vehicle (7) with sufficient time allowance for stopping the vehicle in front of the crossing. Further when it is determined that there is the possibility of bumping with the vehicle (25) entering the crossing, the system gives an alarm indicating the possibility of bumping to the driver at a point where the driver can brake the vehicle (7) in an emergency with time allowance for stopping the vehicle (7) in front of the crossing. When it is determined that there is the possibility of bumping with another vehicle (25) entering the crossing, the system continuously provides controls for decelerating and stopping the vehicle (7) in a range from a point where the system can decelerate the vehicle (7) in an emergency with time allowance for stopping the vehicle (7) in front of the crossing up to a point in front of the crossing.
