Abstract

The invention discloses a co-simulation system of a trackless automatic-guiding combination vehicle. The co-simulation system comprises a control module, a vehicle dynamic module and an interface module, wherein the control module is used as a driving mechanism and is used for establishing related control strategies; the vehicle dynamic module is used as an execution mechanism and is used for executing dynamic responses of the simulation system under the control strategies; the interface module is used as a connection mechanism and is used for realizing the bidirectional connection of variables between the control module and the vehicle dynamic module. The co-simulation system has the advantages of realizing the co-simulation between the control strategies and the vehicle dynamic module, and verifying and simulating automatic guiding control.

Description

technical field [0001] The invention mainly relates to the simulation field of vehicle design, in particular to a collaborative simulation system suitable for trackless self-guiding automobile trains. Background technique [0002] The trackless self-guiding vehicle train is a new type of passenger vehicle train platform with all-wheel steering and multi-axis drive functions. Utilizing the track-following control technology, the self-guiding automobile train can be automatically guided to run like a rail train without carrying or guiding tracks. Small channel width. [0003] The core of the trackless self-guiding vehicle train is the track following control system. The system controls the steering angle of each wheel of the self-guiding train to ensure that the tracks of the wheels in the forward direction of the train coincide, so as to achieve the purpose of all wheels running on the same predetermined track, that is, self-guiding. [0004] Traditional control system sim...
