Automotive development programs require the on-board collection and analysis of data originating from a wide variety of sensors. This paper describes an in-vehicle, general purpose data acquisition and display system that provides a mechanism to acquire, display, and analyze multiple channels of input sensor data. Development engineers can view multiple channels of data in real time and analyze the data immediately afterwards inside the vehicle. Thus, design decisions can be made on the spot instead of waiting for later analysis back at the office. This valuable engineering tool is a rugged, compact, low power unit, and is easy to install and use.
