Title:
DEVICE FOR ESTIMATING MOBILE BODY COLLISION
Document Type and Number:
Japanese Patent JP3424626
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the processing time simplifying the processing for a combination having a low possibility of collision without executing the collision estimating processing of mobile bodies for every period.
SOLUTION: An input device 1 outputs position information signal 4 for the mobile body. A data processing unit 2 calculates the relative distance of the mobile bodies and outputs a collision alarm signal 10. An output device 2 displays a collision alarm. A relative distance calculation part 11 calculates the relative distance and outputs a relative distance signal 5, and it also inputs a collision possibility instruction signal 7 and outputs a precise relative distance signal 6. A maximum relative speed storage part 14 stores the information for the maximum relative speed between the mobile bodies and outputs a maximum relative speed signal 8. A collision prediction part 13 inputs a simplified relative distance signal 9 and the precise relative distance signal 6 and outputs the collision alarm signal 10. A simplified relative distance calculation part 12 calculates a simplified relative distance and outputs the simplified relative distance signal 9.
