摘要:
A control module includes a predicted torque control module that determines a desired throttle area based on a transmission torque request and a desired predicted torque. A throttle security module determines a throttle limit based on the desired throttle area and the desired predicted torque and determines an adjusted desired throttle area based on the throttle limit. A throttle actuator module adjusts a throttle based on the adjusted desired throttle area.

An engine control system of a vehicle comprises a torque module and a chassis request evaluation module. The torque module controls a torque output of an engine based on a driver torque request and selectively increases the torque output based on a chassis torque request. The chassis request evaluation module selectively prevents the increase of the torque output based on at least one of a vehicle speed, a transmission state, and an accelerator pedal position.

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.

An engine control system comprises a derivative module and a slip remediation module. The derivative module determines a mathematical derivative of a driven wheel speed of a vehicle. The slip remediation module, when the mathematical derivative is more negative than a predetermined deceleration, at least one of disables regenerative braking being performed by one or more electric motors, increases an axle torque request, and unlocks a torque converter.

A fault clearing system and method for an engine control system includes a plurality of processor modules to control and monitor the engine and set a plurality of faults. The plurality of processor modules includes an electronic throttle control (ETC) module to control and monitor a throttle of the engine, and a plurality of engine sensors and ETC sensors. An ETC diagnostic module monitors the ETC sensors and engine sensors, with the ETC diagnostic module setting a low voltage induced fault. The ETC diagnostic module will also enter one of a plurality of low voltage states in response to the low voltage induced fault. The ETC diagnostic module selectively controls the ETC module and selectively clears the faults in the ETC module and plurality of processor modules upon entry into one of the low voltage states.
