摘要： PROBLEM TO BE SOLVED: To provide an electronic control system for vehicle capable of standardizing a connector and reducing the cost without the need of increasing the terminal number of the connector for diagnosis even in the case of additionally installing an ECU. SOLUTION: The rewrite control means of all electronic control units is operated by a rewrite command transmitted from a rewrite command means through the connector (step S12), an identification code from the rewrite command means and the identification code intrinsic to a storage means are collated (step S14) and the storage contents of the storage means are rewritten in the case that they match (step S15). Thus, the need of allocating the terminal of the connector for every electronic control unit like the case of selectively operating the electronic control unit requiring rewrite is eliminated.

摘要： PURPOSE:To make it possible to limit the amount of drop in number of revolutions of internal combustion engines and further sufficiently prevent batteries from going dead even if electrical load is rapidly increased in any control mode during reverse idling, by setting the optimal rate of gradually increasing generated energy for each of idle control modes during idling. CONSTITUTION:A first field current limiting means 71 limits the field current of a generator 10 based on parameters detected by a generation parameter detecting means 70 and gradually increases generated energy. A second field current limiting means 72 limits the field current of the generator 10 based on the parameters detected by the generation parameter detecting means 70, and further gradually increases generated energy more slowly than the first field current limiting means 71 does. A selector 73 selects the output of the first field current limiting means 71 at the time of idling of reverse rotation in the open control mode, and the output of the second field current limiting means 72 at the time of idling in the feed back control mode, and outputs the selected output.

Further in an engine control unit 7, based on output signals from various sensors and switches for detecting an operating condition of the engine 1, the ISC valve 5 and an alternator (generator) 8 are controlled. Here during idle operation, when an electric load is applied, quick generating a generating quantity in the generator 8 is suppressed, and further based on each current value of the generator 8 and a battery, whether the electric load is provided or not is decided. A value corresponding to the electric load is calculated to be reduced, to accurately calculate a learning correction value of the ISC valve 5.

摘要： PURPOSE:To accelerate the activation of a catalyst as well as to aim at the simplification of a device in terms of structure and the promotion of low-unit cost of production by igniting a burner simultaneously with engine starting, thereby heating the catalyst, and when a catalytic temperature has become more than the specified value, stopping a combustion of the burner. CONSTITUTION:An exhaust emission control device is provided with a catalytic chamber 12 set up in an exhaust pipe 10 and a burner 14 being installed in close proximity to the upstream of this catalytic chamber 12 and ignited simultaneously with the start of an engine 38. In addition, it is also provided with a branch pipe 18 being branched off from a fuel feed pipe 16 and feeding the burner 14 with fuel, an air blower 20 for feeding the burner 14 with air from the time of igniting the burner 14, a temperature detector 22 detecting a catalyst temperature, and a car-mounted electronic control unit 24, respectively. In this constitution, the burner 14 is ignited simultaneously with engine starting, heating the catalyst as specified, and when the catalytic temperature has become more than the specified value, the burner combustion is stopped. Thus, activation in the catalyst is accelerated, whereby simplification in this device and low-unit cost production are all well promotable.

摘要： PURPOSE:To minutely determine driving modes of a radiator fan and a condenser fan by combining conditions of a water temperature detected by means of a water temperature sensor and a vehicle speed detected by means of a vehicle speed sensor. CONSTITUTION:Detection values of a water temperature sensor 3, a vehicle speed sensor 22, and the like are input into an engine ECU 21. Not only a water temperature, vehicle speed, but also an A/C operation condition is judged by the engine ECU, and an optimum driving mode is determined and output according to the operation condition of the vehicle, while selecting among OFF, LO(LOW), HI(HIGH) drivings. In respect to output modes of a radiator fan 4 and a condenser fan 5, a common signal is output in the HI and LO drivings, so that a required volume of the engine ECU is saved.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of maintaining an output almost constant without influence of residual EGR gas in the case of reducing or suspending recirculation of EGR gas with switching of an operating mode. SOLUTION: A switching condition of a fuel injection mode (operating mode) is decided to be materialized (S10), in accordance with the fuel injection mode, an EGR gas amount (target exhaust gas recirculation amount) is decreased or to zero, when the EGR gas amount is limited (S14), simultaneously with estimating a residual EGR gas amount left in an intake pipe, in accordance with the estimated residual EGR gas amount, a correlated value (target A/F correction amount) KRMEGR is calculated (S22, S26). When switching of the fuel injection mode is actually started, in accordance with this correlated value KRMEGR, an output (Kaf) of an internal combustion engine is suitably corrected (S20, S24).
