Decision of absolute angular position of the steering wheel due to incremental measurement and the measurement of difference speed of the wheel

摘要

Vis-a-vis the chassis of the automobile the steering wheel of that automobile as for the system in order (1) to decide absolute angular position , angular position and the processor in order to sample difference speed (8) it has the device in order to measure the difference speed v/v of the device in order to measure the relative angular position of the steering wheel incremental and the wheel which is installed in the same single spool in (2) and period t. The aforementioned device, although t _n every instantaneously, the absolute angular position which you follow difference speed v/v (t _n) estimator ^* (t _n) with, angular position ^* (t _n) with (t _i) average difference displacement between (t _n) it decides, has the operational expedient which is suited. Here i is variable of the range to n from 0, absolute angular position (t _n) average difference displacement (t _n) with angular position (t _n) is harmony.
