1. A suspension monitoring and adjustment system for an off-road vehicle, the system comprising:
a distance sensor arranged to measure shock displacement of a suspension of the vehicle, the distance sensor including a frame-side accelerometer disposed at a location on the vehicle that is stationary relative to a frame of the vehicle and a wheel-side accelerometer disposed at a location on the vehicle that is stationary relative to a wheel or a suspension linkage of the vehicle, the shock displacement being measured based on a difference between accelerometer data generated by the frame-side and wheel-side accelerometers;
a non-transitory program storage medium on which are stored instructions executable by a processor or programmable circuit to generate an adjustment signal based on shock displacement data generated by the distance sensor;
a processor or programmable circuit communicatively coupled to the distance sensor and operable to receive the shock displacement data generated by the distance sensor and perform the instructions stored on the non-transitory program storage medium; and
a suspension adjuster communicatively coupled to the processor or programmable circuit and arranged to adjust the suspension of the vehicle in response to the adjustment signal, wherein the suspension adjuster includes an actuator arranged to turn a compression adjuster or a rebound adjuster of the suspension in response to the adjustment signal.
