Research on Rotational Angle Measurement for the Smart Wheel Force Sensor

Abstract

The measurement of the rotational angle of the wheel is critical for the smart wheel force sensor (SWFS) to obtain the wheel forces defined in the vehicle coordinates. To simplify the structure of the SWFS and overcome the shortcomings of the traditional angular transducer, a new method to evaluate the rotational speed of the wheel and then calculate the rotational angle is proposed in this paper. In this method, the centripetal acceleration caused by the rotation is recorded by three accelerometers and used carefully. What’s more, the possible sources of error are classified and analyzed. Simulations and stand experiment are carried out to demonstrate the effectiveness of the proposed method.

The Roll Stability Analysis of Semi-Trailer Based on the Wheel Force

“…The division of strain gauges on the strain beams is shown in Fig. 4 [19]. Specifically, the strain gauges, which are used to sense F w x and F w z are located in the middle of the strain beams to sensitive tension and pressure on it [20].…”

Differentially Private Mobile Crowd Sensing Considering Sensing Errors

“…They assumed that the measurement error usually follows a normal distribution. Wang et al proposed a measurement system for the rotational angle of the wheel [24]. They considered sensing error analysis to be a very important problem.…”

“…Therefore, various sensors have been used to control the vehicle. [1][2][3][4][5][6] The number of sensors required for electric vehicles, for which the demand will increase in the future, is even greater. 6,7) Therefore, small sized devices with low power consumption are required, 8,9) and integrated MEMS technology is required to realize these.…”
