1. A method performed by a computer, comprisingdetermining, by a processor, whether a brake pedal was suddenly depressed, based on a comparison between a first magnitude of a forward-backward-acceleration differentiation amount obtained through temporal differentiation of acceleration in forward and backward directions of a vehicle measured by an accelerometer mounted on the vehicle and a second magnitude of an upward-downward-acceleration differentiation amount obtained through temporal differentiation of acceleration in upward and downward directions of the vehicle measured by the accelerometer in a prescribed temporal interval that temporally ranges before and after a timing at which the acceleration in the forward and backward directions was measured;

  • diagnosing, by the processor, whether the vehicle is being driven appropriately based on the comparison of the first magnitude of the forward-backward-acceleration differentiation amount and the second magnitude of upward-downward-acceleration differentiation amount; and

    outputting information indicating inappropriate driving when the determining determines that the brake pedal was suddenly depressed.
