Control unit of oil hydraulic damper

Abstract

Abstract PURPOSE:To perform the stable control without largely changing the crew attitude during the whole braking period by feeding voltage pulses with fixed time width based on the brake sensor output and the preset car speed arrival time respectively to a damping force switching actuator in sequence in the said control unit for a car. CONSTITUTION:When a quick brake is applied during the high speed run, a brake sensor 1 detects, its signal is made a pulse signal with a preset time width via a converter 2 and a capacitor 3, and it is inputted to an actuator via an inverter 5, an NAND gate 6, time constant circuits 8, 9, an NAND gate 7, and an OR gate 10. On the other hand, when a car speed is decreased to a predetermined value, a signal based on the output of a car speed sensor 11 is inputted to the OR gate 10 likewise via time constant circuits 14, 15, an NAND gate 17, and a switching circuit 21. Thereby, both pulse signals are inputted to the actuator only when the brake sensor is operated, thus the crew attitude can be stabilized.
