Estimation of a Speed Hump Profile Using Quarter Car Model

摘要: In the past few years, topics concerning vehicular communications have been in conducting researches. One research topic is to acquire important information (e.g., traffic conditions, weather conditions) necessary disseminate car drivers. Road profile very that drivers who know this advance can use avoid accidents. Speed hump on a road, which one of road information, cause an accident especially at night if driver has never passed through before. This paper proposes technique estimate speed using quarter model. technique, two acceleration sensors are needed install sprung mass and unsprung car. The signals then estimation model get time unit (i.e., height versus time). To obtain space distance), velocities while passing required. Simulation results from Simulink confirm proposed accurately.
