    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 sensor module adjustment circuit includes a device have 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, respectively. A sensor module includes first and second signal conversion modules that generate first and second signal waveforms based on the first and second position values, that include first and second gain modules, and that vary a frequency and a duty cycle, respectively, of the first and second signal waveforms based on the first and second position values. A gain magnitude module determines first and second signal gains of the first and second gain modules, respectively. A signal preset module adjusts the first and second signal gains so that the first and second signal waveforms are equal to first and second predetermined signal waveforms, respectively, when the position of the device is fixed.

    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 is presented. A throttle has a throttle actuator coupled to a throttle plate. A control module is coupled to the throttle actuator. The control module sends a first signal within a gear change time period to the throttle actuator to position the throttle plate for an increased throttle opening. The control module terminates the first signal after the gear change time period. The control module sends a second signal to the throttle actuator to position the throttle plate. The control module positions the throttle plate by the throttle actuator to attain a lower throttle opening limit. A downshift from a higher gear to a lower gear occurs.

    摘要: An engine control system for monitoring torque increase during cylinder deactivation for a displacement on demand (DOD) engine includes a throttle and a controller. The controller adjusts a preload of the throttle prior to a cylinder deactivation event and determines whether a DOD fault is present during the cylinder deactivation event. The controller one of operates the engine without the preload in the deactivated mode and switches the engine back to the activated mode if the fault is present for a predetermined time. The controller cancels the preload if the DOD fault is present and resets the preload if the predetermined period has not expired. The DOD fault includes one of an engine speed fault, a transmission gear fault and a fueled cylinder fault.

    摘要: An electronic throttle control (ETC) system to control an idle speed of an engine includes an accessory that increases a load on the engine and a controller that generates an idle request signal based on the increased load. The controller compares the idle request signal to an idle maximum signal and sets an idle command signal equal to the idle request signal if the idle request signal is less than the idle maximum signal. The controller determines the idle command signal based on the idle request signal, a previous idle command signal and the idle maximum increase signal if the idle request signal is greater than the idle maximum signal.

    摘要: Integrity of data stored in a memory space associated with a vehicle-based control system (such as a traction enhancement system) is verified through the use of sub-module checksums. A checksum for one or more subsystem modules is initially calculated based upon a checksum routine and the values of data residing in the portions of the memory space associated with the subsystem of interest. A global checksum is also initially calculated based upon data associated with the entire memory space. If the global checksum matches an expected value, the subsystem checksum(s) are stored as expected subsystem checksums. During subsequent operation, a second subsystem checksum is calculated and compared against the expected checksum value for the subsystem to verify the integrity of data residing within the memory space associated with the subsystem.
