摘要： A control system includes a device having a position between minimum and maximum positions. First and second position sensors sense the position of the device and generate first and second position values. A sensor module generates a first signal waveform based on the first position value and a second signal waveform based on the second position value. The sensor module varies a frequency of the first signal waveform based on the first position value and a frequency of the second signal waveform based on the second position value. A control module communicates with the sensor module and determines the first and second position values based on the frequencies of the first and second signal waveforms, respectively. The sensor module increases the frequency of the first signal waveform and decreases the frequency of the second signal waveform as the device moves from the minimum position to the maximum position.

摘要： A control system includes a device having a position between minimum and maximum positions. A first position sensor senses the position of the device and generates a first position value. A second position sensor senses the position of the device and generates a second position value. A sensor module communicates with the first and second position sensors and generates a single signal waveform based on the first and second position values. A frequency of the waveform is varied based on the first position value. A duty cycle of the waveform is varied based on the second position value. A conductor has a first end that communicates with the sensor module and a second end that communicates with a control module. The sensor module transmits the waveform to the control module on the conductor. The control module decodes the waveform to determine the first and second position values.

摘要： A throttle control system for a vehicle includes a driver input that generates a control signal and a control module that generates a throttle control signal based on the control signal. The control module determines whether the throttle control signal is within one of a first and a second region, determines a compensation factor from a first look-up table when the throttle control signal is within the first region and determines the compensation factor from a second look-up table when the throttle control signal is within the second region. The control module calculates a compensated throttle control signal based on the compensation factor.

摘要： A redundant position sensing system includes a device having a position between minimum and maximum positions. First and second sensor modules include first and second sensor resistances. A value of one of the first or second sensor resistances increases and a value of the other of the first or second resistances decreases when the device moves from the minimum position to the maximum position. A maximum value of the first sensor resistance ranges between a first maximum value and a second maximum value that is greater than the first maximum value due to a first manufacturing tolerance. A maximum value of the second sensor resistance ranges between a third maximum value and a fourth maximum value that is greater than the third maximum value due to a second manufacturing tolerance. The second maximum value is less than the third maximum value.

摘要： A control system for maintaining powertrain responsiveness adjusts a throttle progression curve to compensate for different vehicle loads. The control system calculates an actual vehicle acceleration rate based on measured vehicle speed for evaluation of total mass being propelled by the vehicle. The calculated actual vehicle acceleration rate is compared to a target vehicle acceleration rate. A throttle progression curve is adjusted based on the results of the comparison so that a subsequent actual vehicle acceleration rate is closer to the target vehicle acceleration rate.

摘要： A hybrid powertrain and a method of controlling a throttle in an engine of the hybrid powertrain are provided. A throttle system has a throttle at an optimal position for the engine to power a first motor/generator when an electric throttle motor is de-energized to minimize current consumption by the throttle motor. The electric throttle motor is energizable to adjust the position of the throttle. A biasing member biases the throttle to a default position when the electric throttle motor is not energized. The hybrid powertrain has a first motor/generator operatively connected to the engine, and a second motor/generator operatively connected to the generator and operable for providing output power. The engine is operable in a predetermined optimal state to provide power to the generator for powering the first motor/generator. The throttle is at a predetermined position when the engine is in the predetermined optimal state.
