Abstract

A positional encoder comprises a moveable member and at least a first and a second sensor. The moveable member is rotatable relative to the first and second sensors, the first sensor being adapted to capture a first component of a current position of the moveable member and to output a first signal corresponding to the first component, the second sensor being adapted to capture a second component of the current position complementary to the first component and to output a second signal corresponding to the second component, wherein the positional encoder further comprises at least a first memory unit holding a plurality of predetermined look-up values, each predetermined look-up value representing a positional value which corresponds to a respective set of at least the first and second signals and being associated with an individual memory address which is formed by concatenating the signals of the respective set, the first memory unit being configured to receive a memory address which is formed by concatenating at least the first and second signals outputted by the first and second sensors, respectively, and to output the predetermined look-up value associated with the received memory address in response.

Abstract

The device (10) comprises a disc (12), carrying a mobile point (P) moving in rotation about an axis (Z). A first sensor (14) cooperates with a first magnetic element (16) fixed to the disc (12) so as to measure an approximate angular position (θa) of the point (P) with respect to an origin (O). Second magnetic elements (22) are arranged circumferentially on the periphery of the disc (12). A second sensor (18) is disposed at the origin (O) so as to measure, for a second magnetic element (22) situated opposite this second sensor (18), the angular position of an upstream end (22A) of this second magnetic element (22) with respect to the origin (O). Means (26) determine which second element (22) is situated opposite the second sensor (18), as a function of the approximate angular position (θa). Means (30) calculate a precise angular position (θ) of the reference point (P) as a function of the second element (22) determined and of the value measured by the second sensor (18).
