Measuring Yaw Rate with Accelerometers 2001-01-2535

This paper presents a new way of measuring yaw rate of the vehicle using two accelerometers. Measurement of yaw rate is inevitable for vehicle stability control systems for contemporary high performance sedans and automatic steering control systems for intelligent vehicles. Compared with accelerometers, the cost of rate gyros used to measure the yaw rate is significantly higher. As an economical software solution to replace the high-cost rate gyros with minimal additional hardware, an algorithm to obtain yaw rate using two accelerometers is proposed in this paper.
