Tire´s inflation and deflation law for CTIS

Take the CTIS in truck SX2150K as an example, tire´s deflation model was set up. This model can be applied to other vehicles by a method called “relative deflation” presented in this paper. Tire´s inflation law was researched based on the relationship between inflation pipes´ flow capacity and the compressor´s displacement. Tires´ inflation speed can be expressed by a two-stage equation which is separated by the critical number of tires. At last, tires´ inflation model was set up. The experimental results show that both the inflation law and the deflation law are practical and effective.
