Valve switching controls for adjustable damper
First Claim
1. A damper system for a vehicle comprising:
- a shock absorber having a plurality of digital valves, wherein each of the plurality of digital valves is controllable to a first position or to a second position, and the shock absorber is operable at one of multiple damping states based on the plurality of digital valves; and
a damper module electrically coupled to each of the digital valves and controlling each of the digital valves to a desired position based on a damper setting received from a master module, the damper module applying an actuation current pulse for switching the digital valve from the first position to the second position, wherein the desired position is either the first position or the second position, the damper module determines a target damping state of the shock absorber based on the damper setting, the target damping state is one of the multiple damping states, and the damper module performs a switch operation to control the plurality of digital valves to a given desired position when the target damping state is different from a present damping state.

Abstract
A damper system for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.
