Title:
CONTROL DEVICE FOR LEARNING OUTPUT OF THROTTLE SENSOR
Document Type and Number:
Japanese Patent JP3732087
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To miniaturize an electronic throttle module and to reduce its cost, without using a conventional, large and expensive sensor provided with an adjusting circuit and an adjusting terminal to obtain a prescribed sensor output by a single sensor.
SOLUTION: A function (relation) of the rotational opening and the output signal of the throttle valve, at the time when the throttle valve is at a fully closed position and a fully opened position which are structurally determined, is computed on the basis of the output signals Va, Vb of the throttle valve having an unregulated output. Thereby, the throttle sensor and an entire electronic control throttle module can be miniaturized, and their costs can be reduced.
