摘要： A vehicle position detecting device according to an embodiment includes a wheel speed acquisition unit, a skid detection unit, a vehicle body speed calculation unit, and a position calculation unit. The wheel speed acquisition unit acquires a wheel speed of a wheel of a vehicle corresponding to rotation of the wheel. The skid detection unit detects a skid of the wheel. The vehicle body speed calculation unit calculates, when the skid is not detected by the skid detection unit, a vehicle body speed corresponding to the speed of a vehicle body of the vehicle based on the wheel speed acquired by the wheel speed acquisition unit, and corrects, in response to detection of the skid by the skid detection unit, the wheel speed acquired by the wheel speed acquisition unit based on correction information and calculates the vehicle body speed based on the corrected wheel speed. The position calculation unit calculates the position of the vehicle based on the vehicle body speed calculated by the vehicle body speed calculation unit depending on the presence of the skid.

摘要： In a mechanical test system, a method of compensating for acceleration induced load error in a load sensor in a mechanical communication with a component comprises measuring an acceleration of the component to obtain an acceleration measurement. A load sensor measures a force applied by the mechanical test system to a test sample in substantially a same direction of the acceleration to obtain a force measurement. The force measurement is modified with a transfer function that includes at least one of a gain correction and a phase correction to compensate for an error value in the force measurement attributed to movement of at least the load sensor when the force is applied to the test sample.

摘要： A method of processing signals from an accelerometer/gyroscopic-based input device includes providing the input device within a vehicle. An accelerometer/gyroscopic-based second device is also provided within the vehicle. The input device is manually actuated while the vehicle is in motion. First signals are transmitted from the input device in response to the manually actuating step. Second signals are transmitted from the second device in response to the motion of the vehicle. The first signals are adjusted dependent upon the second signals.
