    摘要: A system for an engine with a turbocharger system includes a rate determination module, a limiting rate selection module, a throttle inlet absolute pressure (TIAP) calculation module, and a throttle control module. The rate determination module generates a pressure rate value based on a pressure difference between a current TIAP signal from a TIAP sensor and a previous TIAP signal. The limiting rate selection module selects a limiting rate based on the pressure rate value. The TIAP calculation module generates a calculated TIAP signal based on the limiting rate and the current TIAP signal. The throttle control module generates a throttle control signal based on the calculated TIAP signal and actuates an inlet throttle valve of the engine based on the throttle control signal.

    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.

    摘要: A method for monitoring a vehicle battery includes running a timer while the vehicle and a controller are in off states. The method wakes the control module after a first time increment measured by the timer, and sets a second time increment. If needed, the method samples a first state of charge of the battery, and determines whether the battery requires charging prior to the second time increment based upon the sampled first state of charge. Determining whether the battery requires charging may include comparing the first state of charge to a threshold state of charge, or comparing to a second state of charge measured after the second time increment. A diagnostic message may be sent from the vehicle via a communications path, and, if the battery requires charging, an alert message sent to a receiving point accessible to vehicle operator.

    摘要: A system includes an out of correlation (OOC) detection module that detects an OOC error between a first throttle position sensor (TPS) and a second TPS. An out of range (OOR) detection module that detects first and second OOR errors for the first and second TPS, respectively. An OOC counter sets an OOC error when an OOC count is greater than or equal to a first OOC value. An OOR counter sets first and second OOR errors when first and second OOR counts, respectively, are greater than or equal to a second OOR value that is less than the first OOC value. A control module increments the counters when the respective errors occur and sets at least one of the first and second OOR counts equal to the OOC count when at least one of the first and second OOR errors occur after the OOC error.

    摘要: A testing module includes a first input, a second input, an output, a decoder module, an analog to digital (A/D) converter, and an output generator module. The testing module receives a throttle position signal from a throttle position sensor of a vehicle at the first input. The decoder module generates a first throttle position based on a length of at least one pulse in the throttle position signal. The A/D converter generates a second throttle position based on the throttle position signal. The testing module receives user input at the second input. The output generator module generates a test signal in a single edge nibble transmission (SENT) format based on the user input and one of the first and second throttle positions. The testing module outputs the test signal to a control module of the vehicle at the output.
