Three dimensional road-vehicle modeling system

摘要

A three dimensional road-vehicle modeling system includes a personal computer (1) to store data on three dimensional road and virtual vehicle model, a real time simulator (2) to run a simulation based on the data and model, and actual test parts (5 to 16). A three dimensional course line (LC3) of a vehicle (50) is set on the three dimensional road. The simulator (2) converts the three dimensional course line (LC3) on the three dimensional road into a two dimensional course line (LC2) on a two dimensional plane determined based on inclination of the three dimensional road and then converts the two dimensional course line (LC2) into a straight course line (LC1) corresponding to a three dimensional road model on the two dimensional plane based on hypothetical external force acting on the vehicle (50). These three dimensional road and virtual vehicle models are used to evaluate compatibility between the actual parts (5 to 16) and the test vehicle (50).
