摘要:
An electronic selector switch assembly and method for a vehicle includes a housing and selector knob supported by a shaft. A knob position gear is connected to the selector knob and knob measurement gear is connected to the knob position gear. A first sensor senses an angular position of the selector knob. A rack is rotatable about the shaft and selector knob and a rack measurement gear is connected to the rack. A second sensor senses a position of the rack measurement gear. A drive assembly is connected to the rack, and if the knob position, rack position and transmission gear position do not compare, the drive assembly realigns the rack to match the transmission gear position. The methodology periodically senses selector knob and transmission gear positions to determine if there is a mismatch, and locks the selector knob position and adjusts the rack position if there is a mismatch.
摘要:
A method and apparatus for detecting and correcting mismatches between an electronic shifter position and a vehicle's actual transmission gear. The method and system implement a correction scheme that may initially set a period for manual correction, if possible, then initiate automatic correction if correction is required.

A steering angle sensor for determining absolute angular position of a steering wheel of a motor vehicle is disclosed. The steering angle sensor includes a steering angle sensor for determining absolute angular position of a steering wheel shaft of a motor vehicle, the steering angle sensor comprising a first rotational member coupled to the steering wheel shaft; the steering wheel shaft and the first rotational member being rotatable about a first rotational axis through a rotational range including a plurality of revolutions of the steering wheel shaft; a second rotational member rotatable about a second rotational axis, the second rotational member is operably coupled to the first rotational member; a first sensing device including a first sensing element, the first sensing device positioned adjacent to the second rotational member to generate a first signal used to determine rotational position of the second rotational member over a single turn of the second rotational member; a third rotational member rotatable about a third rotational axis, a reduction gear operably couples the second and third rotational members; at least four second sensors positions adjacent to the third rotational member; and the third rotational member includes a plurality of indexing elements disposed on the third rotational member and at least partially circumscribing the third rotational axis, the indexing members and the second sensors cooperatively positioned to generate a second signal used to determine the number of rotations of the steering wheel shaft.

A steering angle sensor assembly 10 for determining absolute angular position of a steering wheel of a motor vehicle and includes a multi-axis detector 24 having an active operating mode and a standby operating mode and being adapted to measure speed and direction of rotation of the steering wheel. The steering angle sensor assembly 10 further includes at least one second detector 26 arranged to form a quadrature encoder to detect movement and direction of the steering wheel when the multi-axis detector 24 is in the standby or powered down operating mode.
