    摘要： A controller estimates a temperature of a catalytic converter in a vehicle and determines an engine speed. The controller shuts off fuel to the engine if the estimated temperature is greater than a maximum temperature of the catalytic converter and the engine speed is greater than a maximum engine speed. If the estimated catalytic converter temperature is greater than the maximum temperature, the controller delays a spark retard request to the engine. The controller updates vehicle torque with an integral torque if an RPM error is within an RPM error range and vehicle speed is less than a maximum vehicle speed for a first period. The controller increases torque to the engine by a proportional torque if an RPM error is within an RPM error range to prevent engine stall. The controller updates the integral torque when the RPM error is within an RPM error range for a first period.

    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： 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： An error condition detection circuit coupled to the motor control circuit reports an error condition when actual motor operation deviates from predetermined desired motor operation. An overcurrent threshold comparator compares motor current with a threshold data value stored in a data storage register, and sets an overcurrent flag when the motor current exceeds the threshold. A current interrogation processor monitors the reported error condition and is programmed to respond to the error condition by iteratively reading the overcurrent flag and decrementing the overcurrent threshold data value by a predetermined decrement amount until the overcurrent flag becomes set. The current interrogation processor is further programmed to report the overcurrent threshold data value extant at the time the flag becomes set as an estimate of electric current.

    摘要： A system includes a trailer sensing module, a position sensing module, a torque reducing module, and an override control module. The trailer sensing module senses when a trailer is attached to a vehicle. The position sensing module senses positions of an accelerator pedal and a brake pedal of the vehicle. The torque reducing module reduces torque output to wheels of the vehicle when both the accelerator pedal and the brake pedal are pressed. The override control module selectively deactivates the torque reducing module when the trailer is attached to the vehicle and when a speed of the vehicle is less than or equal to a threshold.
