摘要： A drive control circuit generates a conduction drive output responsive to a detection output of an accelerator pedal depression degree sensor and an air-intake throttle-valve opening sensor, and controls a driving switch element connected to an air-intake throttle-valve opening control motor. A monitoring control circuit drives a control circuit power supply interruption element that closes a control power supply circuit of the driving switch element, and stops control operation of the driving switch element by a conduction-inhibit output. The drive control circuit can stop operation of a power supply interruption element by a feed-inhibit output. At the time of starting operation, a status signal determines activeness of the feed-inhibit output and conduction-inhibit output, after confirming that those outputs are normal, the inhibition is released. Thus, an engine air-take control device capable of reliably stopping the motor upon occurrence of any abnormality thereby improving safety in control is provided.

摘要： A microprocessor runaway monitoring control circuit with which self-diagnosis of a watchdog timer WDT can be carried out safely and cheaply even during operation of the microprocessor (CPU). A microprocessor 101 supplies first and second watchdog clearing signals WD1 and WD2 to first and second watchdog timers WDT1 and WDT2, and when the both of the watchdog clearing signals WD1 and WD2 stop, the microprocessor 101 is reset by way of a logical connector circuit 122. The microprocessor 101 has failure diagnosing means 103 which intentionally stops the first watchdog clearing signal WD1 and diagnoses the response of the first watchdog timer WDT1 on the basis of a monitor signal MN1 and stops the second watchdog clearing signal WD2 and diagnoses the response of the second watchdog timer WDT2 on the basis of a monitor signal MN2, whereby diagnosis of the watchdog timers WDT1, WDT2 is carried out without the microprocessor 101 being stopped.

摘要： Evacuation operation performance is improved when any abnormality occurs in an electronic throttle control system. When any serious abnormality occurs, a first abnormality storage element (133) operates, a load relay for a power supply circuit (104a) of a throttle valve open/close controlling motor (103) is de-energized to operate a first alarm and display (109a). Thus a first device carries out the evacuation operation by a fuel cut control. When any slight abnormality occurs, a second abnormality storing element (136) comes to actuate thereby a second alarm and display (109b) being operated. Thus a second device carries out the evacuation operation using together a throttle valve opening control by the motor 103 and the fuel cut control.

摘要： A vehicular electronic control apparatus is provided with a program memory, a data memory, a RAM, a microprocesser, a reference data storage memory, a data memory abnormality judging section, and at least two transfer sections for a RAM. The reference data storage memory stores reference data corresponding to variable control data stored in the data memory. The data memory abnormality judging section judges whether the variable control data stored in the data memory are normal or abnormal. The first transfer section transfers and writes the variable control data from the data memory to the RAM. The second transfer section writes estimated variable control data based on the reference data from the reference data storage memory to the RAM.

As a suppression rotational speed, a lower limit threshold at a stop, a rotational speed substantially in proportion to the output of an accelerator position sensor, a rotational speed substantially in inverse proportion to the output of a throttle position sensor, or a default threshold rotational speed is selected, and multiple escape running can be carried out.
