    摘要： 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.

    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.

    摘要翻译： 控制器估计车辆中催化转化器的温度并确定发动机转速。 如果估计的温度大于催化转化器的最高温度，并且发动机转速大于最大发动机转速，则控制器关闭发动机的燃油。 如果估计的催化转化器温度大于最高温度，则控制器将发动机的火花延迟请求延迟。 如果RPM误差在RPM误差范围内并且车辆速度小于第一时段的最大车速，则控制器以整体转矩更新车辆扭矩。 如果RPM误差在RPM误差范围内，则控制器会通过比例扭矩增加发动机的扭矩，以防止发动机停转。 当RPM错误在第一个周期的RPM错误范围内时，控制器更新积分转矩。

    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.

    摘要： 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.
