摘要： PROBLEM TO BE SOLVED: To provide an electronic control device capable of suppressing increase in power consumption, even when there is a circuit operating in a standby state.SOLUTION: An internal power circuit lowers a battery voltage BATT supplied always from an external side to generate a standby power voltage VOS3. A timer continues to measure an elapse of time in a standby state, after a main relay 3 is turned off and supply of a power voltage +B is interrupted. Measured time data of the timer are saved to a save register during a time measurement operation of the timer. When a stop condition for stopping the time measurement operation of the timer is satisfied, a control circuit stops the operation of the internal power circuit. When the main relay 3 is turned on, the internal power circuit is activated to start its operation again by the control circuit, so that the measured time data saved to the save register are restored to the timer.

摘要： PROBLEM TO BE SOLVED: To obtain sensor signal data at an accurate timing synchronous to a crank angle from the data converted to digital data in processing the sensor signals.SOLUTION: The sensor signal of CPS2 is converted to a digital signal in an AD conversion circuit 7 via an input circuit 4 to remove noises by a digital filter 8. The data of RAMa are moved to RAMb whenever the signal is converted into AD to store the AD converted data in the RAMa of RAM9. A sensor signal processing device 1 processes the signals in a time span shorter than in a sampling cycle. A trigger generation circuit 11 synchronizes with the crank angle from an NE sensor 3 and creates a trigger signal offset in the delay time of the filter. The data synchronized with the timing of the trigger signal are linearly interpolated and calculated from the AD converted data before and after the time when the trigger signal is generated. Amount of stored data is minimized to have an inexpensive structure for obtaining quick and accurate data.

摘要： PROBLEM TO BE SOLVED: To easily change the variation of the voltage value of a supply signal that can be generated by a single power supply unit. SOLUTION: As a result of a signal path being connected to an input terminal 36 to allow a first intermediate signal from a power-side regulator 20 or another external signal that does not pass through the power-side regulator 20 to be selectively input into any supply-side regulator 30, a supply signal can be generated on the basis of the signals. Therefore, as a result of the relevant supply-side regulator 30 being connected to a signal path by which the other external signal is input, a supply signal having a voltage value differing from that when the first intermediate signal is input can be generated. As a result of the signal to be input into the supply-side regulator 30 being changed, only the voltage value of the supply signal generated by the supply-side regulator 30 is changed. Therefore, the variation of the voltage value of the supply signal that can be provided as a power supply unit 1 can be changed. COPYRIGHT: (C)2010,JPO&INPIT
