摘要:
A control system for a vehicle includes a first counter that indicates a first count of a number of cylinders of an engine of the vehicle that are fueled. A second counter indicates a second count of the number of cylinders that are fueled. A control module determines a secure count based on the first count and the second count. The control module adjusts torque output of the engine based on the secure count.

A method and control module for controlling an engine includes a requested torque module that generates a requested torque and a maximum toque capacity module that determines a maximum torque capacity corresponding to a maximum torque capacity of the engine. A launch trim torque threshold determination module determines a launch trim torque threshold. A comparison module that compares the requested torque and the launch trim torque threshold. An output module that applies a fast rate limit to the requested torque up to the launch trim threshold when the requested torque is less than the launch trim torque threshold and a shower rate limited torque request when the requested torque is greater than the launch trim torque threshold.

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:
An engine control module comprises a torque control module, an engine speed (RPM) control module, and an actuator module. The torque control module determines a first desired torque based on a requested torque. The RPM control module selectively determines a second desired torque based on a desired RPM. The torque control module determines the first desired torque further based on the second desired torque when the engine control module is transitioning from an RPM control mode to a torque control mode. The RPM control module determines the second desired torque further based on the first desired torque when the engine control module is transitioning from the torque control mode to the RPM control mode. The actuator module controls an actuator of an engine based on the first and second desired torques.

An engine control system comprises a pedal torque determination module, a driver interpretation module, and an actuation module. The pedal torque determination module determines a zero pedal torque based on a desired engine torque at a zero accelerator pedal position and a minimum torque limit for an engine system. The driver interpretation module determines a driver pedal torque based on the zero pedal torque and an accelerator pedal position. The actuation module controls at least one of a throttle area, spark timing, and a fuel command based on the driver pedal torque.

A system for detecting contamination of an air filter for an internal combustion engine includes an air pressure sensor disposed downstream of the air filter, an air flow sensor disposed in an air intake system of the engine, and a control module in communication with the air pressure sensor and the air flow sensor. The control module is configured to estimate an atmospheric pressure based on a signal received from the air pressure sensor. The control module is further configured to determine a contamination level of the air filter based on an air flow rate provided by the air flow sensor and a pressure drop across the air filter based on a pressure difference between the estimated atmospheric pressure and a second pressure measurement from the air pressure sensor that corresponds to the provided air flow rate.

摘要:
A multiple state automotive data storage and analysis procedure in which vehicle operating parameters are continuously logged in a first state while monitoring the vehicle operating condition for occurrence of any of a predetermined set of trigger conditions. Upon occurrence of any of the predetermined set of trigger conditions, logging operations are suspended and confirmation of occurrence of any of a predetermined set of storage conditions occurs in a second state. If such occurrence is confirmed, a third state is entered in which the logged parameter values are transferred to more permanent memory devices for off-line analysis thereof. If such occurrence is not confirmed, operations of the first state are resumed.
