Abstract :
Smartphone three-axis acceleration sensors mounted on an electric vehicle experimental module in conjunction with motor wheel encoders are used to measure wheel slip. Kalman filter is used to correct noise from sensor data. Integration of sensor data has a drift effect for the calculated vehicle speed. A Linear Fit method is evaluated for drift removal. A traction control method is proposed and simulated.
