Rate of consumption gauge with variable rate of consumption limits

Abstract

The invention is an improved method and system to monitor vehicle operation state and operator requests. It combines into a single gauge information indicating current vehicle operating state and ability to increase power assist using a display of instantaneous rate of consumption usage superimposed over available rate of power consumption limits. The invention can display whether an operator is requesting power assist, regenerative braking or battery charging while also displaying the available amount of each under present operating conditions. A vehicle system controller (VSC) or similar type controller is connected to the gauge, which can limit instantaneous rate of consumption usage or charge to the available rate of power consumption or charge limits. The invention can use analog needles or LEDs in various configurations as well as adding warning lamps or chimes when the instantaneous rate of consumption usage approaches or exceeds the available rate of power consumption limits.
