About realization of the mode of real time when modeling the car in Simulink on the simulator with the mixed reality

Abstract

The main objectives of imitating modeling of the movement, fluctuations of controllability of the car with involvement of the commixed reality and simulators are considered(examined). It is revealed that the problem place of their decision is the insufficient speed of the existing computers (even with frequency of processor of 4-5 GHz) due to the need of message modeling in strip of 0-28 Hz at step 0.0006-0.001 with to receive acceptable convergence with experiment. The separation offered earlier and parallelization of the calculations on computers connected by powerful network demands use of the special software of division of tasks and their synchronization which is still inaccessible because of sanctions and high cost.

For increase in performance it is offered to divide calculations on the 3rd computers through the three-level combined network, including breakdown of mathematical model into front and rear suspension in separate flowcharts for more equal distribution of calculation on integrators in Simulink that the Windows operating system could distribute(allocate) better on processor cores.

On the first (Raspberry minicomputer) reading of parameters from governing bodies of the car for drive is offered to carry out them in network, on the second main more powerful computer itself of modeling process, on the third visualization of road situation, information transfer on 6-Dof the platform of the vibrostand on CAN BUS network.

At the expense of it it is promoted in Simulink of the performance of calculations by 1.6 times.

Further expedient it is represented to computers still of separation of calculations on cores with use of the special software.
