    摘要: A control system according to the principles of the present disclosure includes an operation control module, a fault detection module, a remedial action module, and a reset module. The operation control module controls operation of a vehicle system. The fault detection module detects a fault in the operation control module when the operation control module fails an integrity test. The remedial action module takes a remedial action when the fault is detected. The reset module resets the operation control module when the fault is detected and the remedial action is not taken.

    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.

    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 throttle control module comprises a primary throttle position module, a redundant throttle position module, and a remedial action module. The primary throttle position module transforms a primary throttle area signal indicating desired throttle area into a primary throttle position signal indicating a first desired throttle position of a throttle valve. The throttle valve is actuated based upon the primary throttle position signal. The redundant throttle position module transforms a redundant throttle area signal indicating desired throttle area into a redundant throttle position signal indicating a second desired throttle position of the throttle valve. The remedial action module selectively generates a remedial action signal based upon a comparison of the first and second desired throttle positions.

    摘要: A diagnostic system includes N dedicated diagnostic modules that each correspond with a respective one of multiple control systems. The N dedicated diagnostic modules each generate status signals indicating results of respective diagnostic tests. A diagnostic error time monitor determines an accumulated error time value between error events for each of the control systems based on the status signals. The diagnostic error time monitor selectively reports a fault to a respective one of the N dedicated diagnostic modules based on the accumulated error time value.

    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 control module for a vehicle is provided. The control module includes at least one device driver implemented by the control module. The at least one device driver generates a control signal to a device of the vehicle and generates a state of health signal based on an operational status of the device driver. A processor implemented by the engine control module monitors the state of health signal from the at least one device driver and generates a running reset command to the at least one device driver based on a fault status of the state of health signal.
