摘要： PURPOSE:To provide a power supply for mobile electronic equipment in which a voltage is fed from a single simplified power supply circuit to a large number of electronic equipments mounted on an automobile. CONSTITUTION:A chopper power supply circuit 12 and a series power supply circuit 15 constitute a power supply section 11. Battery power supply 14 being fed through an ignition switch 13 to the chopper power supply circuit 12 is turned ON/OFF at a predetermined duty and rectified to produce a predetermined DC voltage which is then outputted through the series power supply circuit 15. The power supply section 11 is also provided with a backup power supply circuit 17 directly connected with the battery power supply 14. The power supply circuit 17 produces a voltage higher than a first voltage required by the electronic equipment and thus produced voltage is fed to a simple power supply circuit corresponding to each electronic equipment wherein the voltage is dropped to the first voltage required by the electronic equipments.

摘要： PURPOSE:To hold the normal operation state of an electronic apparatus by by-passing a chopper power supply and a series power supply to supply power from a battery to the electronic apparatus in a state dropping the power supply voltage of the battery at the time of starting a startor or the like. CONSTITUTION:When the voltage of the battery 11 is normal and an ignition switch is turned on, power from the battery 11 is applied to a microcomputer 15 through the serial connection of the chopper power supply and the series power supply 14. When the starter is driven and the voltage of the battery 11 is suddenly dropped, the voltage drop is detected by a detecting circuit consisting of resistors 18, 19, a comparator 20 and a reference power supply 21, a transistor 22 and a switching element 17 are turned on and the voltage is impressed to the computer 15. Thereby the electronic apparatus can be normally driven even when the voltage of the battery 11 is in a low state.

摘要： PURPOSE:To improve the control response property by changing the duty ratio of pulse output for controlling the ratio of air to fuel in response to revolution speed of the engine, too. CONSTITUTION:After shaping voltage from an ignition coil IG through a wave form shaping circuit 4a, the frequency of its output is converted to voltage by an F/V converter 4b and then the voltage output from the converter 4b is converted to frequency by a V/F converter 4c. Upon an output from this converter 4c, a saw tooth wave generator 4d produces a saw tooth wave with a predetermined slope. An output from an O2 sensor 3 is integrated by a ratio-of-air-to-fuel control circuit 4e. Thus obtained integration output is compared with the output from the saw wave generator 4d by a comparator 4f. An output from the comparator is amplified and then supplied to an actuator 5 to operate it.

摘要： PURPOSE: To provide a communication system in which no collision on a communication line is present and data are not destructed by providing priority orders to the first to nth electronic controllers of slave units beforehand and determining the transmission order of response messages. CONSTITUTION: An engine controller 1, a transmission controller 2 and an air conditioning controller 6 are provided as the plural slave units to be mounted on a vehicle and data communication is performed with an externally connected fault diagnostic tester 5 as a master unit. The communication of one to n is performed through one communication line 3 and a connector 4 and the priority order is determined beforehand for the respective electronic equipments. When the fault diagnostic tester 5 transmits a request message to the respective electronic equipments, their own response messages are transmitted in an order from the electronic equipment whose priority order is high. Since the response message is transmitted after the prescribed standby time after the message of the equipment of which priority order is high is completed, the messages do not collide on the communication line.

摘要： PURPOSE:To prevent the car speed from exceeding the standard value and to improve the safety, by deciding the reducing ratio of cylinders to stop of the plural cylinders, and stopping to feed fuel to those cylinders to stop, when the running speed of the vehicle is higher than a specific standard speed. CONSTITUTION:When a set switch 2 is handled to move a vehicle to a constant speed running, the then running speed is detected by a car speed sensor 1 and stored in a computer 4 as a set speed. And when the set car speed is lower than a specific car speed, the opening of a throttle valve 11 is fixed at the first opening (about 2/3 opening), and when the set speed is higher than the specific speed, the throttle valve 11 is fixed at the second opening (fully opened). Then the reducing cylinder ratio to the set car speed is set initially, and the cylinder reducing control is started by a cylinder reducing command signal through a cylinder reducing control circuit 7. In this case, the cylinder reducing ratio is converted depending on the result of comparison between the detected value of the running speed and the preset standard value.
