Automotive Instrument Cluster Implementation with Motion Based Simulation Ian Duncan, Kevin Hulme Ph.D., and Kemper Lewis Ph.D. Abstract Vehicle simulation is a safe and practical way to examine research questions that can be performed in a physical vehicle. Supplementing vehicle simulation with practical peripherals such as an automotive instrument cluster can provide realism to the simulation environment, immersing the user.[1] The use of mechatronics in such a system is a useful tool for adding such items, therefore enhancing the authentication of the simulation environment. Mechatronics is a multidisciplinary field that incorporates mechanical, electrical, computer, and control systems engineering to implement embedded designs.[2] Through this synergy, the incorporation of an actual automotive instrument cluster can be integrated with the motion base simulator in the New York State Center for Engineering Design and Industrial Innovation’s (NYSCEDII) vehicle simulation lab. This design lays a foundation for future instrument cluster design and simulation analysis within NYSCEDII, and adds significant realism and capability for future vehicle and driver studies.

Keeping the objective in mind, the integration of the instrument cluster and motion based simulator is accomplished by using a mechatronic device called a microcontroller. This device receives PC commands through its serial port and translates the signals into appropriate motions within the instrument cluster. A description of the above diagram is given below. • Inputs from motion base (driving pedals and steering wheel) are sent to PC • PC sends commands to servo motor controller (via C/C++ language) • Servo motor controller communicates to servo motor to move in specific direction (via Pulse Width Modulation, PWM) • The movement corresponds to actuation of the gauge dials within the instrument cluster.
