Heavy Commercial Road Vehicles were involved in 31% of road accident fatalities in India in 2019, despite making up just 5.34% of the country's overall vehicle population. This alarming statistic points toward the inefficiency of the current safety systems in the vehicle. The existing systems like Advanced Driver Assistance Systems (ADAS), Active Vehicle Safety Systems (AVSS) and Engine Management Systems (EMS) require precise wheel speed measurements to process the longitudinal vehicle dynamics accurately. To improve safety, comfort and engine efficiency, reliable, affordable, and high-performance wheel speed sensors (WSS) must be integrated into driver assistance systems. As the vehicle suspension system is mounted above the WSS assembly, it cannot suppress the WSS vibration resulting from road undulations. Therefore, the vibrations caused by the road undulations on WSS may affect the performance of the current WSS systems. This research attempts to address the impact of vibrations on the WSS signals. The objective of this research is to perform vibration analysis to study wheel speed sensor performance due to road undulations, braking, loading, vehicle longitudinal speed, and road friction coefficient and to conduct sensitivity analysis on passive variable reluctance (VR) WSS and active hall effect (HE) WSS for various sensor parameters. WSS vibration was measured from an experiment vehicle for a range of speeds to study the wheel speed sensor performance due to road undulations. Data synthesized from simulations and the experimental results were compared to gain confidence in the experimental results. WSS vibration due to braking, loading and road friction coefficient was evaluated on a Hardware-in-loop (HiL) setup. The results from the analysis comprehended that the road undulations cause a 5% to 7% increase in wheel speed for the studied speed range. Sensitivity analysis of VR and HE WSS for various sensor parameters will be investigated using three-dimensional finite element simulations.
