<p>An idle stop control apparatus includes a first starting device (2), a second starting device (5), a battery voltage detecting device (7) a storage device (9), a battery voltage estimating section (4) and a control section (4). The first starting device (2) starts an engine (1) in response to a start operation performed by a driver by transmitting power to the engine (1). The second starting device (5) starts the engine (1) in response to a prescribed idle stop cancellation condition by transmitting power to the engine (1). The battery voltage detecting device (7) detects a voltage of a battery (3) serving to supply an electric current to the first starting device (2) and the second starting device (5). The storage device (9) stores a voltage difference between a minimum voltage of the battery (3) occurring when the engine (1) was started by the first starting device (2) and a minimum voltage of the battery (3) occurring when the engine (1) was started by the second starting device (5). The battery voltage estimating section (4) estimates a minimum voltage of the battery (3) expected to occur if the engine (1) is started by the second starting device (5) based on the voltage difference stored in the storage device (9) and a minimum voltage of the battery (3) detected by the battery voltage detecting device (7) at a time when the engine (1) was being started by the first starting device (2). The control section (4) automatically stops the engine (1) when a prescribed idle stop condition is satisfied. The control section (4) further prohibits starting of the engine (1) by the second starting device (5) in response to the idle stop cancellation condition when the estimated minimum battery voltage estimated by the battery voltage estimating section (4) is equal to or smaller than a prescribed battery voltage.</p> |
