International Classification:

F02D 11/10
F02D 11/04

US Classification:

123399, 123400

Abstract:

A drive-by-wire throttle control apparatus and method includes a variable resistance sensor. A contact arm can be mechanically connected between a thumb lever and a variable resistance sensor. The variable resistance sensor possesses a resistive film that includes a fixed resistor and a variable resistor configured from a carbon film. As the thumb lever rotates, the contact arm traverses the resistive film, thereby altering the resistance of the variable resistor, determining the position of the thumb lever and thereafter generating a signal based on the sensed position. The signal can be sent to an ECU (Electronic Control Unit) in the form of a varying voltage, which in turn controls the throttle of a vehicle.

International Classification:

B60K 13/00

US Classification:

180335

Abstract:

A drive by wire contactless throttle control which includes a contactless Hall-effect magnetic sensor. The Hall-effect magnetic sensor can be located in a mounting bracket in contactless association with a thumb lever on a handle bar. A magnet can be placed in a slot inside the thumb lever with a bonder and filled with an epoxy. The Hall-effect magnetic sensor senses the magnetic field produced by the magnet as the thumb lever rotates and determines position of the thumb lever and generates a signal based on the sensed position. The signal can be sent to an ECU (Electronic Control Unit) utilizing electrical wires in the form of varying voltage, which in turn controls throttle of a vehicle, such as an all terrain vehicle, snowmobile, etc.

Appl. No.:

12/194760

Inventors:

Anand Chandran - Springfield IL, US
Al Cable - Springfield IL, US

International Classification:

G05G 1/08

US Classification:

74504

Abstract:

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.

US Classification:

324662, 29 2541, 701101

Abstract:

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.
