摘要： A backup RAM for storing pieces of diagnosis data regardless of the cut-off of an electric power is provided in a portion of a RAM. In cases where the detection of an unusual condition by a throttle sensor or a water temperature sensor is judged by a CPU in a current processing routine, a first checking value indicating that the backup RAM is in a renewing period is stored in a checking region of the backup RAM, and pieces of previous diagnosis data stored in a data access region of the backup RAM in a previous processing routine are copied to a temporary refuge region of the backup RAM. Thereafter, pieces of updated diagnosis data obtained in the current processing routine are stored one by one in the data access region in place of the previous diagnosis data, and a second checking value indicating that the backup RAM is in a renewal finishing period is stored in the checking region. In cases where the first checking data is stored in the checking region when the electric power cut off is again supplied, the previous diagnosis data stored in the temporary refuge region are returned to the data access region and are read out according to a request from a diagnosis checker.

摘要： A heat dissipation structure includes a heat-producing electronic component on a substrate, a thermally conductive case, and grease. The electronic component and the substrate are housed in the case. The grease is provided between the case and the electronic component or the substrate for transmitting heat produced by the electronic component to the case. The case has contact surfaces that contact with the grease. The contact surfaces have free energy equal to or higher than 20 mN/m and roughness equal to or larger than 1.0 μm.

摘要： A switching power circuit is provided with a power bypass circuit. The bypass circuit supplies a power supply voltage of an input terminal by bypassing a FET and a π-filter during a period after supply of the power supply voltage is started until the power supply voltage reaches a predetermined threshold level corresponding to a reference voltage. Even if start of the switching operation of the FET is delayed because of the operation of a soft start circuit, the power supply voltage supplied to a load through the switching power circuit is raised at earlier time.

摘要： An ECU includes a microcomputer that has an integrated flash memory. An initial writing flag is set in the microcomputer before an initial writing to the flash memory. The microcomputer enters into a writing mode when the flag determines permission of data writing. When the data-writing to the flash memory is completed, the flag is cleared.

摘要： A first judgment circuit and a second judgment circuit are adapted to set a judging signal high when a judgment data sent from a microprocessor indicates failure. The high level judging signal triggers a forced idle command connected to a motor driver, to be high level whereby the motor is forcibly suspended. Subsequently, when a reset command is accidentally transmitted by the microprocessor due to an unexpected fault, a first judging signal from the first judgment circuit is reset to low level. However, a second judging signal from the second judgment circuit remains high level. As a result, the forced idle command stays high level.
