  • Method and system for selecting between two sensor output signals in an electronic throttle system
    Patent number: 6899080
    Abstract: A method and system for selecting one of a plurality of voltage signals generated by a plurality of sensors in response to a common sensor input. The method determines which sensor to use based on a comparison the of the output of the sensors to each other and to known values.
    Type: Grant

  • Compensating voltage controller system
    Patent number: 6435160
    Abstract: An electronic throttle control apparatus includes a variable voltage generator, such as an H-driver, controlling the positioning effort of an electronic throttle motor by generating a variable voltage signal. A current sensing element is coupled to the H-driver and generates a voltage proportional to motor current. A microprocessor is coupled to the H-driver and the current sensing element. The microprocessor determines electronic motor resistance based upon the voltage generated by the H-driver and the current sensing voltage signal. The microprocessor may then modify controller gains based upon the calculated electronic throttle motor resistance.
