摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine stop control device and an internal combustion engine stop control method, accurately determining whether the internal combustion engine is stopped.
SOLUTION: A controller 5 estimates the minimum voltage of a battery 3 in restart after the stop of the engine 1, based on a present state of the battery 3, and permits the idling stop when the estimated minimum voltage of the battery 3 is higher than a predetermined value. The controller 5 calculates an estimation line relating to the voltage of the battery 3 based on voltage characteristics when the voltage of the battery 3 reaches a stable area in the past stop of the engine 1, and estimates voltage just before this restart of the battery 3 based on the calculated estimation line. By subtracting a voltage drop necessary to restart the engine 1 from the estimated voltage just before the restart, the minimum voltage of the battery 3 in this restart is estimated.

摘要： PROBLEM TO BE SOLVED: To more suitably control the power generation of a generator in response to the running state of a vehicle. SOLUTION: This generator controller for a vehicle first initially sets a reference power generation voltage Vm* and a Flag etc. used for determining power generation restrain in an acceleration state (S100). The generator controller determines the operating state of the vehicle (S110), samples a voltage across a battery in a decelerating state, and calculates a battery average voltage Vav (S150). The generator controller updates the on/off of the Flag and a value of the reference power generation voltage Vm* according to a value of the Vav (S160-S190). Thereafter, when the vehicle is transferred to an acceleration state, whether it is in a state of Flag=ON or not is determined (S210). When it is the Flag=ON, power generation is restrained (S220). When it is the Flag=OFF, a power generation target voltage is returned to the reference power generation voltage Vm*, and the power generation restraint is released (S200).

摘要： PROBLEM TO BE SOLVED: To accurately determine the deterioration of a rechargeable battery due to irregular variation in load.
SOLUTION: Charge and discharge current I of the rechargeable battery and voltage V between terminals are inputted (S104). When the inputted charge and discharge current I is approximately zero with the specified variation, a load history P as an indication showing the history of load on the rechargeable battery corresponding to the charge and discharge current I is calculated (S106 to S108). Voltage V when the load history P is a specified recharging history is set as polarization voltage Vc. At the same time, voltage V when the load history P is a specified discharging history is set as polarization voltage Vd (S110 to S 118). Then, when the voltage difference ΔV as a variation of polarization voltages Vc and Vd exceeds threshold Vref, the rechargeable battery is determined as deteriorated (S122). When a uniform standard is set as load history P, since the voltage difference ΔV when the load history P is at that standard directly reflects the degree of deterioration of the rechargeable battery, the deterioration can be determined more accurately.
