摘要
Disclosed are self-calibrating load sensor systems for active aerodynamics devices, methods for making or using such load sensor systems, and motor vehicles equipped with a self-calibrating load sensor system to govern operation of the vehicle's active aero device(s). An active aero sensing system includes a load sensor that mounts to the vehicle body, and detects downforces on the vehicle. A memory device stores mapped vehicle downforce data calibrated to the motor vehicle. A vehicle controller receives downforce signals generated by the load sensor, and calculates an average downforce value from these signals. The controller determines if the average downforce differs from a calibrated downforce value retrieved from the memory device. If so, the controller responsively applies an offset value to subsequent downforce signals received from the load sensor, and dynamically controls operation of the active aero device based, at least in part, on these signals modified by the offset value.
