摘要： First, second, and third processor modules selectively execute a test having N test states while an ignition system of the vehicle is off. N is an integer greater than one. The N test states each include: the first processor module setting a first output to a first predetermined value for one of the N test states; the second processor module setting a second output to a second predetermined value for the one of the N test states; the third processor module setting a third output to a third predetermined value for the one of the N test states; a predetermined expectation for the one of the N test states; and at least one of the first, second, and third processor modules indicating a fault when a fourth output is different than the predetermined expectation. A control module sets the fourth output based on the first, second, and third outputs.

摘要： An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.

摘要： Methods and apparatus are provided for ensuring that a throttle increase accompanying a change in the number of active cylinders of an internal combustion engine will not occur too long with more than a selected fraction of all the cylinders activated, so as to not startle a driver. The apparatus comprises an electronic controller that generates the throttle increase if less than all the cylinders are requested to be activated. A determination is made as to whether the number of cylinders being fueled is equal to or less than the selected fraction. A timer is started if the number of cylinders being fueled is greater than the selected fraction. The throttle increase is turned off if the amount of time measured by the timer exceeds a threshold before the number of cylinders being fueled becomes either less than or equal to the selected fraction.

摘要： A system and method for securely flashing a controller, where the controller includes at least one main processor and at least one secondary processor, and where the processing duties are distributed between the processors. A programming tool provides a content file to be flashed and a digital signature to the controller. The controller calculates a hash value of the content file, decrypts the digital signature using a public key to generate a decrypted hash value, compares the decrypted hash value to the calculated hash value, and determines that the content file is valid if the decrypted hash code matches the calculated hash value, where one or more of the steps of calculating the hash value, decrypting the digital signature, comparing the decrypted hash value to the calculated hash value and determining that the content file is valid, is performed by the main processor for the secondary processor.

摘要： A system comprises a general-purpose memory, a lockable memory, a memory management unit, and a processor. The general-purpose memory includes data for a first set of addresses. The lockable memory includes data for a second set of addresses. The memory management unit selectively writes data to one of the general-purpose memory and the lockable memory and selectively locks the lockable memory by preventing writes to the lockable memory. The processor instructs the memory management unit to unlock the lockable memory before requesting a write to one of the second set of addresses.
