Abstract
To design a rear suspension of BAJA SAE vehicle it must be considered many parameters as robustness, vertical and lateral. This work shows a proposal to idealize a favorable lateral dynamic, with a big range of oveerster.
This paper presents a double wishbone rear suspension, common used in this kind of vehicle, with a new toe controller system which target is to raise the oversteering characteristic.
It was used multibody virtual analysis to simulate a real use of the vehicle. To better understand and measure the improvements of the system a method of understeering/oversteering gradient calculation was used.
The results show that the OMA system induces the oversteer characteristic on the prototype which is very estimated on an off-road vehicle.
