    摘要: A control system comprising a powertrain relay diagnostic module that determines a single continuous period that a powertrain relay voltage is less than an ignition relay voltage, that compares the single continuous period to a single predetermined period, and that diagnoses a powertrain relay out of correlation (OOC) error when the single continuous period is greater than or equal to the single predetermined period, and an ignition relay diagnostic module that diagnoses an ignition relay OOC error when the ignition relay voltage is less than the powertrain relay voltage for a first predetermined cumulative period within a first predetermined total period.

    摘要: A system for detecting memory corruption in an engine control module includes a variable selection module, an output module, an input module, and a response comparing module. The variable selection module selects a variable of a control system for testing. The output module outputs a predetermined value of said variable to a memory location where said variable is stored in said engine control module. The input module receives a response of said control system to said predetermined value when said predetermined value is written in said memory location. The response comparing module compares said response to a predetermined range and determines that said memory location is defective when said response is not within said predetermined range.

    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 control system for a vehicle comprises a throttle control module and a diagnostic module. The throttle control module controls a position of a throttle of the vehicle and compensates for changes in effective opening area of the throttle due to coking. The diagnostic module reports a coking value to a user based upon an amount of compensation performed by the throttle control module. A method comprises controlling a position of a throttle of a vehicle; compensating for changes in effective opening area of the throttle due to coking; and reporting a coking value to a user based upon an amount of compensation performed.

    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.
