摘要： In one embodiment, a total fuel injection amount is calculated from a torque required by an engine. A division ratio of a pre-injection amount that achieves both suppression of ignition delay of fuel from a main injection and suppression of a peak value of a heat production ratio of combustion from the main injection is calculated. Upper and lower limit guards are given to the obtained divided amount, and the divided injection amount is calculated. The injection amount of the main injection is obtained by subtracting the divided injection amount from the total fuel injection amount.

摘要： A systematic fuel injection control technique for compression self-igniting internal combustion engines capable of executing an auxiliary injection prior to a primary injection is provided, with which it is possible to optimize an injection mode for the primary injection and the auxiliary injection. In a common rail diesel engine capable of executing at least a main injection and a pre-injection as an operation of fuel injection from an injector, the pre-injection is executed by being split into a first pre-injection and a second pre-injection. The injection timing and the injection amount of each fuel injection is controlled such that some of the fuel injected in the first pre-injection combusts by self-ignition, and the remainder of the fuel does not combust until fuel is injected in the main injection, but combusts together with the fuel injected in the main injection. Also, the injection timing of each fuel injection is controlled such that the fuel injected in the first pre-injection and flowing along a swirl flow in the cylinder overlaps the fuel injected in the subsequent main injection.

摘要： Under the condition of a large variation in motor torque demand, the significant torque change may lead to some vibration of a vehicle to temporarily heighten an angular acceleration. The temporary rise of the angular acceleration may cause the angular acceleration to exceed a preset threshold value slip and result in misdetection of the occurrence of a ‘phantom’ skid in an angular acceleration—based skid state determination. The drive control of the invention accordingly specifies a potential for misdetection of the occurrence of a ‘phantom’ skid when the variation in motor torque demand exceeds a preset threshold value at step S108. The drive control thereby does not execute skid occurring state control with torque restriction but performs grip state control at step S116.

摘要： An abnormality judging section detects the occurrence of an abnormality based on various signals input to a master control CPU, and judges that abnormal event. A data selecting section selects inherent data which is inherent to the abnormal event in accordance with the judged abnormal event from data input to the master control CPU and data generated in the master control CPU. A writing section writes the freeze-frame data to an EEPROM together with nine common data irrespective of a difference in abnormal events. A reading section reads desired freeze-frame data from data stored in the EEPROM in accordance with a request from a diag tester.

摘要： A minimum reference voltage and an operation inhibiting reference voltage are set as the criteria for detecting the conditions of power supply of a low voltage power source system including a low voltage battery. The operation inhibiting reference voltage is lower than the minimum reference voltage and represents a threshold value ensuring the normal operation of an apparatus that establishes the power source of a high voltage power source system. When the power source voltage of the low voltage battery is lower than the minimum reference voltage but is not lower than the operation inhibiting reference voltage, a converter is activated to charge the low voltage battery to the minimum reference voltage whole system of, for normal functions. When the power source voltage of the low voltage battery is lower than the operation inhibiting reference voltage, on the other hand, operation of the whole system is inhibited.
