摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device which starts an internal combustion engine by determining a cylinder without discharging unburned fuel when a cam angle sensor dose not work normally.
SOLUTION: In a crank rotor, a single missing tooth 300 and continuous missing teeth 302 are alternately formed at each 90°CA, and in a cam rotor, a tooth 310 is formed corresponding to the missing tooth 300 at this side of the top dead center of a cylinder #1 and the missing tooth 302 at this side of the top dead center of a cylinder #3. The fuel pressure of the fuel supplied from a high-pressure pump is different between top dead centers of the cylinder #1 and the cylinder #2, and different between top dead centers of a cylinder #3 and a cylinder #4. In the case that a cam angle sensor dose not work normally and does not output a cam angle signal for detecting the tooth 310 of the cam rotor, the cylinder can be determined without injecting the fuel based on the crank angle signal for detecting the missing teeth 300 and 302 and the fuel pressure of the high-pressure pump detected by the fuel pressure sensor. The fuel is injected from a fuel injection valve based on a result of the determination of the cylinder, and the injected fuel is ignited by an ignition plug.

摘要： PROBLEM TO BE SOLVED: To confirm in a short time that a timer circuit in an electronic control device is normal. SOLUTION: An onboard electronic control device includes a microcomputer which operates as power is supplied by the turning on of an ignition switch (IGSW), and a soak timer which is constantly supplied with power. The microcomputer performs a soak timer abnormality detection process each certain period of time when started as the IGSW is turned on. When the process is performed for the first time, the soak timer is started (S320), and a counter CT 1 for measuring the time (one count time) that a timer value, i.e., the count value of the soak timer, varies by one is cleared (S330). The counter CT 1 is incremented each time (S350), and if it is determined that the timer value has changed (S370: YES), a determination is made as to whether the soak timer is normal or abnormal according to the value of the counter value CT 1 at that time (S380-S395). Consequently, it is confirmed that the soak timer is normal in almost one count time. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To initialize data through a simple initializing procedure by once disconnecting a battery and then reconnecting the same when adopting a configuration for storing data in a nonvolatile memory instead of a volatile memory.SOLUTION: When a battery 22 is connected to an ECU 21, a simple power supply circuit 49 generates a simple power supply voltage Vp2 from a voltage VBATT of a power supply line 28, and a power-on reset circuit 51 shifts a reset signal Sr to L. A latch circuit 50 outputs a battery state signal Sb of H indicating that the battery 22 has been disconnected. Thereafter, when an ignition switch 23 is turned on, a main processor 34 of a microcomputer 33 initializes a flash memory 35 on condition that the battery state signal Sb is at H, and then outputs a setting signal Ss to a power supply IC32.

摘要： PROBLEM TO BE SOLVED: To suppress a force in an abrupt acceleration direction from being applied on a vehicle when torque is increased by turning off a throttle motor.SOLUTION: An electronic throttle which is controlled by this electronic control device fixes an opening of a throttle valve by an energization force of a spring to a predetermined opening necessary for retreat travelling when the throttle motor is turned off. When the motor of the electronic throttle is turned off during the idling of an engine, the throttle valve is opened up to the opening. Therefore, when a failure occurs in electronic throttle control by microcomputer during idling (when a failure in the microcomputer is detected and a throttle change amount at that time is large), a throttle power supply relay circuit for connecting a power supply to the motor is turned off to turn off the motor, and also a fuel cut signal is switched to an on-state, and the transmission of an injector signal is interrupted to cut fuel temporarily. In addition, in a process prior to an end of fuel cut, a fuel cut amount is reduced gradually to suppress a rapid torque increase at the end of the fuel cut.

摘要： PROBLEM TO BE SOLVED: To provide an electronic controller capable of making the safety of control compatible with the reliability of an operation at a high level. SOLUTION: This controller controls an engine according to a control program that is written in flash ROM, periodically checks storage content of the flash ROM with SAM check and performs processing (S390) that stops the engine when abnormality is detected (S370: NO). In such cases, write area data that shows a storage area (described as a write area below) in which a control program is written is written in the flash ROM, sum check processing which performs SAM check reads write area data from the flash ROM, discriminates the write area (S320) and performs SAM check of only the write area (S335 to S380). Then, control is stopped only at an abnormal time when there is actual damage, and the safety of control and the reliability of an operation are made compatible with each other.

摘要： PROBLEM TO BE SOLVED: To allow an electronic device to cope with both the half-duplex and the full duplex communication systems and to decrease number of communication ports and number of connector terminals. SOLUTION: In the case of conducting half-duplex communication, an engine electronic control unit ECU 10 outputs a high level from a control port 23. Then a changeover switch SW connects a reception port 22 and a 1st terminal 25. Since data that are sent/received include a flag XSEL=0 (selection of 1st ECU), a 2nd ECU 50 aborts the data even when receiving the data. On the other hand, in the case of conducting full duplex communication, the ECU 10 outputs a low level. Then the changeover switch SW connects the reception port 22 and a 2nd terminal 26. Since the engine ECU 10 transmits data including the flag XSEL=0 (selection of 1st ECU) and a flag XTXOK=1 (full duplex communication enabled), when the 2nd ECU 50 receives the data and start transmission but the 1st ECU 40 aborts the data.
