    • In an in-vehicle electronic control apparatus (ECU), when a microcomputer stops operation, a timer IC starts the count-up operation. When the count value reaches a preset value, a signal from the timer IC becomes high and a power supply voltage is outputted from a power supply IC to activate the microcomputer. The microcomputer reads the count value from the timer IC when it starts the operation. If such a count value has exceeded the specified value, the microcomputer determines occurrence of a failure. Therefore, if the timer IC cannot activate the power supply IC, the microcomputer can detect a failure upon activation with turning on of an ignition switch.
    • 在车载电子控制装置(ECU)中,当微型计算机停止动作时,定时器IC开始向上计数。 当计数值达到预设值时,来自定时器IC的信号变高,并且从电源IC输出电源电压以启动微型计算机。 微型计算机从开始运行时读取定时器IC的计数值。 如果这样的计数值超过规定值,则微机判定故障的发生。 因此,如果定时器IC不能激活电源IC,则微计算机能够通过点火开关的接通来检测激活时的故障。

    • In an electronic control unit for a vehicle, control data is stored in a volatile memory until a predetermined time passes after an ignition switch is turned off. This makes it possible to greatly reduce the frequency at which data is written into a nonvolatile memory. When the predetermined time has passed after the ignition switch is turned off, the control data stored in the volatile memory is written into the nonvolatile memory. Thereafter, the power supply from a power supply circuit to the volatile memory is stopped. Consequently, it is possible to store the control data reliably in either the volatile memory or the nonvolatile memory. It is also possible to reduce the dark current in the volatile memory.
    • 在用于车辆的电子控制单元中,控制数据被存储在易失性存储器中,直到点火开关关闭之后经过预定时间。 这使得可以大大降低将数据写入非易失性存储器的频率。 当在点火开关关闭之后经过预定时间时,将存储在易失性存储器中的控制数据写入非易失性存储器。 此后,停止从电源电路向易失性存储器的供电。 因此,可以将控制数据可靠地存储在易失性存储器或非易失性存储器中。 还可以减少易失性存储器中的暗电流。

    • Only predetermined frequency components included in an ion current flowing between an ignition plug and the ground are extracted from the ion current by means of a low pass filter and a high pass filter as a knock detection signal, that is, a signal used for knock detection. This knock detection signal is then subjected to A/D-conversion in an A/D-converter to generate A/D-converted values which are subsequently supplied to a processing unit employed in a digital signal processor. In the processing unit, the A/D-converted values are subjected to a discrete Fourier transform (DFT) frequency analysis. Knock determination based on data obtained from the DFT frequency analysis results in information indicating the operating state of the internal combustion engine. That is, in the frequency analysis of the A/D-converted values obtained as a result of the A/D-conversion of predetermined frequency components of the ion current, a peculiarity such as the occurrence of a knock or the superposition of noise on the signal is clearly recognized.

    • To execute high-accuracy control employing communication data of a microprocessor while attempting standardization of the microprocessor, a host microprocessor is provided with a ROM, RAM, CPU, and DMA controller, and a KCS microprocessor is provided with a ROM, RAM, CPU, and DMA controller. The host microprocessor and the KCS microprocessor are connected by a bidirectional communication line. At a predetermined cycle, the CPU of the host microprocessor sends data in the ROM relating to the content of control of the KCS microprocessor to the RAM of the KCS microprocessor. Engine information (A/D values and so on) are sent from the KCS microprocessor to the host microprocessor at a cycle of 4 ms, but sending of ROM data from the host microprocessor to the KCS microprocessor is performed during free time in this sending cycle. The ROM data is divided into a plurality of blocks, and the data is sent block by block.
