Dynamic detection pre-warning device for preventing rollover of freight car on curved road

2008 
The utility model relates to a dynamic detection pre-warning device for preventing rollover of freight car on a curved road, which is characterized by comprising a steering wheel angle sensor, a yaw rate sensor, an inclinometer, another inclinometer, an alarm prompt device and an electronic control unit. The steering wheel angle sensor is arranged on a steering column below the steering wheel of a freight car; the yaw rate sensor is arranged at the intersection position of two middle axial lines at the bottom of the carriage of the freight car; the inclinometer is arranged at the cross point on the carriage projected by the vertical middle axial line at the bottom of the carriage of the freight car and the rear shaft; the other inclinometer is arranged at the midpoint of the rear shaft; alarm prompt device is arranged on a middle console of the cab; the electronic control unit comprises a single chip; and the single chip is provided with a dynamic detection algorithm module of centroid height and an anti-rollover pre-warning algorithm module. The utility model can utter corresponding alarm commands in accordance with the difference between the lateral acceleration and the rollover acceleration of the freight car and the preset rollover alarming range, thereby effectively preventing the rollover accident on the curved road, and protecting the running of the freight car and the personal safety of the driver.
