Description
We report a study on railroad vehicle control with highly-sensitive microelectromechanical systems (MEMS) inertial sensors. The control system could be useful to realize automatic and safe-and-secure railroad systems with minimum ground equipment. As a first step of this study, we analyzed railroad vehicle behaviors by using equation of motion; an analytical model was developed for railroad vehicle braking operation. Calculation results indicate that the vehicle acceleration has to be detected with sub-1mG (1 G = 9.8 m/s2) resolution in order to control the position of railroad vehicles. Our recent research suggests that sub-1mG sensing with MEMS inertial sensors has a potential of the development of the proposed future railroad vehicle control technology.
