Abstract

The invention relates to a simulation modeling method of an intelligent vehicle road navigation environment model, which comprises the following steps: establishing an intelligent vehicle road navigation simulation environment; setting virtual vehicle radar, traffic lights, road conditions including ramps, corners and speed limit points in the simulation environment; according to the scene controlstrategy, establishing the simulation model of intelligent vehicle road navigation environment. According to the invention, the multi-source information of the intelligent vehicle can be uniformly constructed in a simulation environment model, the workload and the cost of establishing the driving environment model are reduced, high simulation authenticity is exhibited, and the simulation of the large-scale and complex road traffic environment can be easily established.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to a simulation modeling method for an intelligent vehicle road navigation environment model. Background technique [0002] In recent years, driving simulator is a safe and efficient simulation tool, which is mainly used in the experimental development of new automotive technology and traffic safety research. The road traffic environment provides the driver with a virtual driving environment, combined with the driving equipment to produce a real car driving feeling, which is the key to the driving simulation experiment. The existing modeling method mainly builds a large number of scene elements through professional 3D modeling software, and then uses professional control strategy software to write the control model. This method has a large workload, high cost, and poor authenticity, and is not suitable for building large-scale The problem of road traffic environment. Co...
