摘要： An on-vehicle electronic control device is provided, which includes an auxiliary microprocessor and subjects a microprocessor allocated to a main part of control to an external diagnosis, thereby improving reliability of performance. A microprocessor (110a) including a nonvolatile program memory (115a) into which a control program is written is serially connected to an auxiliary microprocessor (120a) including an auxiliary nonvolatile program memory (125). The microprocessor (110a) and the auxiliary microprocessor (120a) functions in cooperation to control on-vehicle electric load groups (104a and 104b) in response to input signals from on-vehicle sensor groups (102a and 102b) and an on-vehicle analog sensor group 103a. The nonvolatile program memory (115a) and the microprocessor (110a) are subjected to runaway monitoring performed by a watchdog timer (130) and to an external checksum diagnosis performed periodically by the auxiliary microprocessor (120a). If an anomaly occurs in the run away monitoring, the external checksum diagnosis, and a checksum interval, parts of electric loads are cut off of power supply by load power relay (107a).

摘要： A first control circuit section (master station) and a second control circuit section (substation) communicate with each other via series-parallel converters. The master station includes regular transmission device and transmission-permitting signal generation device; and the sub station includes regular report device, confirmation reply device relative to a transmission data from the master station, and an unprocessed data table. The unprocessed data table prevents jam-up in upstream communication from the sub station to the master station, enabling to carry out timely regular transmission and regular reporting. Transmission from the sub station to the master station is performed based on a transmission-permitting control signal that the master station generates. Consequently, it is possible to execute communication error processing and diminish communication control burden on the master station while properly performing the regular transmission and regular report between the master station and sub station.

摘要： A microprocessor 20a controls an electrical load group 12 responsive to content of a non-volatile program memory 25a and operation state of an input sensor group 11. A monitoring control circuit section 30a sequentially transmits a large number of question items with an inquiry packet, and compares response content from the microprocessor 20a with correct answer information to carry out an error determination. The microprocessor 20a diagnoses an interval of receiving an inquiry packet to monitor in reverse the monitoring operation of the monitoring control circuit section 30a. Thus, in an electronic control unit having a microprocessor built-in, a monitoring control circuit is obtained that alternatively executes at regular intervals a part of control programs to carry out operation inspection during operation.

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： 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： Escape running performance at the time of the occurrence of an abnormality in an electronic throttle control system is improved. At the time of the occurrence of a severe abnormality, an abnormality storage element is operated, and an electric supply load relay of a throttle valve driving motor is de-energized to return a throttle valve to the default, and further, an alarm display is actuated, and an upper limit engine rotational speed is suppressed by control of a fuel injection valve, and escape running is carried out. 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.
