A method and system for determining a drive ratio of a supercharger in a vehicle propulsion system includes sensing an engine speed of an engine in the propulsion system, providing an engine speed signal based upon the sensed engine speed, sensing an inlet air pressure of the supercharger, providing a supercharger inlet air pressure signal based upon the sensed supercharger inlet air pressure overa dedicated communication channel to a processor in the vehicle, and determining, in the processor, a drive ratio for the supercharger based upon the engine speed signal, the supercharger inlet air pressure signal, and a lobe count of the supercharger. 用于确定车辆推进系统中的增压器的传动比的方法及系统包括感测推进系统中的发放机的发动机速度、基于所感测到的发动机速度提供发动机速度信号、感测增压器的入口空气压力、在所感测到的增压器入口空气压力的基础上通过专用通信信道将增压器入口空气压力信号提供至车辆中的处理器以及在处理器中基于发动机速度信号、增压器入口空气压力信号以及增压器的叶片数确定增压器的传动比。
