A method for the detection of rotation of the wheel with the use of a one-dimensional acceleration sensor

摘要

Embodiments relate to tpms, the one single-axis acceleration sensor for the measurement of the direction of rotation of the tire in a tire localization methodology use. In the case of an embodiment permits the known axle position of the acceleration sensor in the tires of the evaluation by means of an integrated circuit for determining the left - and, on the right, positioning of a tire and - of the acceleration and delay amount of. Because of the two components of the measured acceleration signal, first of all, the direction of acceleration of the vehicle and, secondly, the oscillation modulation due to gravity, has the generated wave shape, as is known, differences between the signals of the left and right tire of a accelerating and decelerating vehicle on. The effect of the oscillation modulation to the direction of acceleration of the vehicle can be used for the purpose of rotation of the direction of the tire and thus the this localized wheels as well as the acceleration - and to identify delay amount of.
