摘要： An engine starter controller for a vehicle equipped with an idle-stop controller includes a user-start circuit, an auto-start circuit, a switch, and a failure detector. The user-start circuit energizes a starter when a driver starts an engine. The auto-start circuit energizes the starter when the idle-stop controller automatically restarts the engine. The switch circuit switches an energization circuit for energizing the starter from the user-start circuit to the auto-start circuit after the user-start circuit starts to energize the starter by causing the auto-start circuit to energize the starter and by putting the user-start circuit into a forced state where the user-start circuit is forced to stop energizing the starter. The failure detector determines whether the auto-start circuit energizes the starter when the energization circuit is switched to the auto-start circuit.

摘要： When a vehicle speed is decreased to a first deceleration threshold value which is greater than zero, an idle reduction controller executes a first engine-shut-down to automatically shut down an engine. In a monitoring period from when the vehicle speed falls below a second deceleration threshold value which is greater than the first deceleration threshold value until when the vehicle speed becomes the first deceleration threshold value, when a steering operation is conducted by a driver, the first engine-shut-down is prohibited. Then, when the vehicle speed exceeds the second deceleration threshold value, a prohibition of the first engine-shut-down is canceled.
