Vehicle position determination method, involves calculating mixed-relative position by mixing evaluation process, when reliability of one evaluation process is below preset minimum reliability

摘要

#CMT# #/CMT# The method involves measuring a global system for mobile communications (GSM) data by which two relative positions are determined by evaluation processes which have reliabilities. One reliability is compared with a preset minimum reliability, and a vehicle relative position is determined by averaging the positions if the reliability is above the minimum reliability. A mixed-relative position is calculated by a mixing evaluation process, which possesses a mixing process reliability lying above the minimum reliability, when the reliability is below the minimum reliability. #CMT# : #/CMT# An independent claim is also included for a vehicle comprising an electrical controller. #CMT#USE : #/CMT# Method for determining a position of a vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The method reduces the number of evaluation processes such that it determines the position of the vehicle in an accurate manner, and saves processing power, and hence reducing the operating cost of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a system illustrating a method for determining a position of a vehicle. 10 : Vehicle 12 : Global system for mobile communications receiver 14.1 : Global system for mobile communications base station 16 : Radio signal 18 : Electronic controller.
