Off-road vehicle suspension monitoring and adjustment system

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 processor or programmable circuit communicatively coupled to the distance sensor and operable to generate an adjustment signal based on the shock displacement data generated by the distance sensor;
• 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.

A suspension monitoring and adjustment method for an off-road vehicle, the method comprising:

• providing 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;
• generating an adjustment signal based on shock displacement data generated by the distance sensor;
• and
• adjusting the suspension of the vehicle in response to the adjustment signal.
