摘要： A control system for an internal combustion engine having a throttle valve disposed in an intake passage of the engine. A target intake air amount of the engine is calculated, and an intake pressure of the engine is estimated. A wide-open intake air amount is calculated according to the engine rotational speed, and a theoretical intake air amount is calculated according to the wide-open intake air amount and the intake pressure. The wide-open intake air amount is an intake air amount corresponding to a state where the throttle valve is fully opened, and the theoretical intake air amount is an intake air amount corresponding to a state where no exhaust gas of the engine is recirculated to a combustion chamber of the engine. further, an exhaust gas recirculation ratio is calculated using the theoretical intake air amount and the target intake air amount, and a target output torque of the engine is calculated using the target intake air amount and the exhaust gas recirculation ratio. The engine is controlled using the target output torque.

摘要： When a battery as an energy source for propelling an electric vehicle is repeatedly charged and discharged, the calculated remaining capacity of the battery tends to suffer a large error due to an error of a current sensor which detects a battery current. In order to detect the remaining capacity with high accuracy, a remaining capacity 1 detected on the basis of an integrated value of a discharging current and a remaining capacity 2 detected on the basis of the output power of the battery at a present time are compared with each other, and the remaining capacity is determined depending on the result of comparison. The output power of the battery at the present time depends on the remaining capacity at the present time. Thereafter, after the battery is charged and discharged in repeated cycles, the remaining capacity 1 is presumed as suffering a large error, and the remaining capacity 2 is determined as the remaining capacity, so that the remaining capacity can be detected with accuracy.

摘要： A system is provided to effectively use the electric charge of a capacitor provided for an inverter in an electric vehicle when the capacitor discharges and to decrease the time required for discharge. An inverter for converting the DC electric power of a main battery into AC electric power to drive a traveling motor is provided with a smoothing capacitor to be charged through a precharge contactor. A DC/DC converter is used to charge a sub-battery using the electric power from the main battery when an electric vehicle runs. When the capacitor discharges, the electric charge of the capacitor is used to charge the sub-battery through the DC/DC converter. Because no discharge circuit is used when the capacitor discharges, it is possible to complete discharge in a short time and without the generation of heat by the discharge circuit.

摘要： A state of charge (SOC) measuring apparatus for a battery device is provided capable of detecting accurate state of charge based on integrating charge and discharge current. The state of charge measuring apparatus carries out data substitution for displaying and controlling state of charge depending on the upper limit SOC or lower limit SOC. The integrated SOC obtained by integrating charge and discharge currents is corrected into the corrected SOC by the incremented corrected value incremented at every data substitution time. The state of charge measuring apparatus corrects the integrated SOC at every data substitution such that the difference between the integrated SOC and the corrected SOC becomes larger, and when the integrated SOC is smaller than the upper limit SOC and larger than the lower limit SOC, the corrected SOC is displayed on the display portion as the displaying and controlling SOC.
