<p>PROBLEM TO BE SOLVED: To improve the fuel consumption by controlling the switching of generating current or exciting current of a generator in synchronism with the change of stroke of an internal combustion engine and suppressing fluctuation in the r.p.m. of engine thereby preventing the engine r.p.m. from increasing and lowering the idle r.p.m. SOLUTION: When the engine r.p.m. is higher than the idle r.p.m. and the battery voltage is low (power generation is requested), power generation is controlled such that the battery voltage matches a target level which is specified times as high as a reference voltage Vref. When the engine r.p.m. is lower than the idle r.p.m., power generation is inhibited even if a power generation request (Hi level) is outputted from a comparator 341 during a compression stroke of 180-360 deg. crank interval from a moment of ignition (ti). Consequently, the engine load is reduced in the compression stroke and fluctuation is suppressed in torque and speed. According to the controller, fuel consumption can be improved by lowering the idle r.p.m. while avoiding engine stall.</p> |
