PURPOSE:To enable the extremely quick detection of quick brake and to expedite the post-processing thereof, for example, the point of the time for starting controlling a shock absorber by providing a processor which decides the quick brake in accordance with the stroke signal corresponding to the controlled variable of a brake pedal. CONSTITUTION:When the stroke signal corresponding to the treading extent, that is, controlled variable of a brake pedal 3 is outputted from a stroke sensor 1, the amplified signal is converted to a digital signal by an analog-digital converter 6, and is inputted to processor 7 including a microprocessor unit. Whether the value (VN-VN-1)/t obtained by taking the difference between the stroke quantity of this time calculated from the above-mentioned digital signal taken into the processor, that is, voltage VB and the voltage VN-1 calculated already by the signal taken into the processor previously and dividing said difference by a period (t) is a prescribed value VO or above or not is decided in a step 13 for deciding the quick brake. If said value (VN-VN-1)/t is the value VO or above, the processor judges that the quick brake is acted and controls a damper strongly, that is, controls a shock absorber strongly. |
