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 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.

摘要： An operation amount detecting unit 17 detects an operation amount of a throttle grip from a zero position. A basic throttle opening degree computing unit 18 computes a basic throttle opening degree corresponding to the operation amount. A throttle opening degree additional value computing unit 20 outputs as a target throttle opening degree a value obtained by adding the basic throttle opening degree with a throttle opening degree additional value corresponding to the operation amount when the operation of the throttle grip is performed within a small operation region corresponding to an idle operation. The throttle opening degree additional value computing unit 20 outputs as the target throttle opening degree the basic throttle opening degree when the operation of the throttle grip is performed without the small operation region.

摘要： To detect opening/closing of a neutral detection hydraulic switch by a detection apparatus and detect breakage of a wiring line connected between the detection apparatus and the switch. Since a second contact and an ECU are connected to each other by two wiring lines, even if one of the wiring lines is broken, opening/closing of the neutral detection hydraulic switch can be detected through the remaining one of the wiring lines. Since different voltages are applied to the wiring lines through resistance type voltage dividing circuits, the occurrence of the wire breakage can be detected making use of the fact that the voltage detected by the ECU upon opening of the neutral detection hydraulic switch when one of the wiring lines is broken is different from the voltage when none of the wiring lines is broken.

摘要： An engine control system and an engine control method for improving the ability to start an engine by changing the execution timings of predetermined sumchecks in ROM to shorten the time required for initialization of the system. Upon starting an ECU with a power supply supplied from an AC generator as a result of an operation of a kick starter, a CPU initialization, which includes a hardware reset and a software initialization, is executed. An ignition timing calculation sumcheck, which is required for the calculation of an ignition timing, and injection timing calculation sumcheck, which is required for the calculation of an injection timing, are not executed in a period of the software initialization. Instead, they are executed during BG (background) processing after a movement to routine processing, which upon completion of the software initialization, starts the ECU to permit driving and controlling an igniter and a fuel injector.
