    摘要: Erroneous diagnosis caused by a case where hardware other than an ALU (arithmetical and logic unit) has a function to access a RAM directly due to the construction of a CPU is to be prevented. In order to do so, interrupt is prohibited at every predetermined diagnosis timing. Then, determination is made as to whether a start-up of a DMAC (direct memory access controller) is approved or not, and only when the start-up is not approved, the diagnosis is performed to a diagnosis object RAM by previously determined diagnosis unit bytes at a time through a read/write method. When failure of the RAM is determined, the diagnosis procedure is advanced to an NG process. When the start-up of the DMAC is approved, the diagnosis of the diagnosis object RAM is prohibited, and the address of the object RAM is stored in a memory so that the object RAM is diagnosed at a next diagnosis timing.

    摘要: The present invention securely prevents the erroneous switching of the combustion mode to the stratified charge combustion, and avoids deterioration of the driving performance. In order to do so, apart from a software determination device inside a main CPU for performing the permission determination on the switching to the stratified charge combustion based on an input signal related to the engine drive condition, a hardware detection circuit (gate array) is equipped for performing the permission determination on the switching to the stratified charge combustion mode based on the input signal related to the engine drive condition. The main CPU is equipped with a combustion mode order device for finally ordering the stratified charge combustion by permitting the switching to the stratified charge combustion only when the two permission determinations both permit the switching to the stratified charge combustion. Further, a sub CPU is mounted which is equipped with a fail-safe device for based on the final permission determination from the main CPU and the permission determination from the hardware determination device, performing a fail-safe process when the two determinations are inconsistent.

    摘要: An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop.

    摘要: An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is “0,” and the engine rotational speed of “0” is displayed on the meter.

    摘要: An electronic throttle control system and method are provided. The system includes a throttle valve, a motor configured to drive the throttle valve, and a throttle position sensor configured to detect an angle of the throttle valve. The system further includes an engine rotating speed detector, and a controller. The controller is configured to drive the motor to control the angle of the throttle valve. The controller is configured to initially set a lower limit value of the angle to an angle which is greater than a full closure angle of the throttle valve by a predetermined amount. The controller is further configured to, when a rise in an engine rotating speed is detected, re-set the lower limit value to reduce it by a predetermined amount to control the engine rotating speed to within a predetermined value from the preset idle speed.
