Abstract
In a method for minimizing errors in sensors used for a recording apparatus of car accidents, data including acceleration, yaw-rate, vehicle speed measured at the transmission, and steering angle are first measured by sensors, then error in forward acceleration is corrected on the basis of vehicle speed measured at the transmission. Next, error in lateral acceleration is corrected on the basis of vehicle speed and steering angle measured by a steering angle sensor, then error in rotational angular velocity is corrected on the basis of steering angle and vehicle speed. Finally, data is recorded as corrected values.
