摘要:
A drive-by-wire non-contact capacitive throttle control apparatus and method of forming the same. A capacitive position sensor is provided, which includes a stationary electrode and a rotatable electrode. The rotatable electrode can be attached to a throttle lever such that the rotatable electrode rotates as the throttle lever rotates. The capacitance between the rotatable electrode and the stationary electrode varies with the position of the throttle lever. The position of the throttle lever can be measured by measuring the capacitance between the electrodes and a signal can be generated based on the sensed position. The signal can be electrically transmitted to an ECU (Electronic Control Unit) utilizing one or more electrical wires. The signal can be sent in the form of a varying voltage, which in turn controls the throttle of a vehicle.
摘要:
A drive-by-wire throttle control apparatus and method of forming the same. The apparatus includes a Hall-effect magnetic sensor. A thumb lever can be assembled into a mounting bracket inside a cylindrical hole, which can rotate to a desired angle. The thumb lever can be mechanically connected to a magnet holder, which includes a magnet, utilizing a key-slot mechanism. The magnet holder can be placed inside a housing that allows the magnet holder to rotate and restrict other movements. When the thumb lever rotates, the lever rotates the magnet holder, which in turn detects the position of the throttle utilizing a varying voltage output from an associated Hall-effect chip. A signal can be generated based on the sensed position.
