Abstract

PURPOSE:To prevent sudden speed-up of the detected acceleration inducing an error operation by outputting a value previously set as an acceleration signal in case a detected speed signal is low. CONSTITUTION:An output signal of a speed generator 3 is converted into a detected speed signal 23 by a waveform shaping section 11 and a speed conversion section 12, and the detected speed signal 23 is converted into an acceleration signal 24 by a differentiator 13. A control section 16 is controlled so as to output the acceleration signal 24 by a switching unit 15 in case the detected speed signal 23 is above a certain level and is controlled so as to output a signal 25 of the level previously set in case under the level. According to such constitution, even if a speed detection system where a detected speed suddenly changes with a certain speed is used, stable acceleration signal can be obtained.
