Design of two-wheel self-balanced electric vehicle based on MEMS

We present the design of two-wheel self-balanced electric vehicle based on MEMS. In this paper, system structure and functions, signal processing of micro-silicon accelerometer and micro-silicon gyro will be mainly discussed. Two-wheel self-balanced electric vehicle is designed based on the model of the single inverted pendulum system. The system uses two parallel wheels to maintain balance and uses micro-silicon accelerometer and micro-silicon gyro as position detection sensors. The operator standing on it can control the vehicle to move forward or backward by shifting the gravity centre and turns the moving direction through the steering pole.
