International Classification:

H02P 800

US Classification:

738663

Abstract:

A method and an apparatus are provided for displaying a value of a measured parameter for an engine-driven vehicle, such as the speed of an engine. The apparatus includes a microcontroller which receives a data signal from a data concentrator. The data signal contains information relating to the value of a parameter which has been measured by a sensor or other measuring device. Based on the value of the data signal the microcontroller generates one or more motor control signals. The motor control signals are used to drive a stepper-motor. The motor rotates an output shaft which has a pointer mounted near one end of the shaft. The angular position of the output shaft upon rotation corresponds to the value of the parameter and the pointer helps to provide a human-readable format for the parameter value.
