Abstract
A shock absorber controller controls a shock absorber so that a damping force thereof is altered to an increased magnitude after the elapse of a predetermined delay time when it is determined that a vertical movement of a vehicle body exceeds a first threshold value, and the damping force is maintained at the increased magnitude for a predetermined hold time. After a determination inhibiting time elapses, it is determined whether or not the vertical movement of the vehicle body exceeds a second threshold value. When it is determined that the vertical movement has become greater than the second threshold value, the damping force of the shock absorber is maintained at the increased magnitude for a predetermined time even after the predetermined hold time elapses.
