Regarding the issue of HMMWV rear steering system

[jingwu chen]

Hi all,

I am currently simulating the power performance of a four-wheel steering car and have not found an interface to control the rear steering when using the HMMWV model. Does Chrono have a similar solution?

Thanks in advance for your support.

Hi all,

Through experimentation, I have found a solution to control rear wheel steering, which is to add a rear axle steering system to HMMWV_VehicleFull.cpp, as shown in the first picture in the attachment.
But I encountered some other problems during the simulation process, and I hope to get everyone's help. After adding rear wheel steering, I encountered some problems while analyzing the vehicle's climbing performance, as shown in the second picture in the attachment. At this time, the rear wheels of the vehicle showed strange steering phenomena (I did not provide steering input), and the vehicle had a large angle of steering when climbing. Is this caused by the incorrect way of changing the rear axle steering?

Thanks in advance for your support.
