Abstract
A system for controlling an idle-stop vehicle includes an ECU which carries out idle stop when the idle-stop permission conditions are established, and engine restart and engagement of a forward clutch when the idle-stop release conditions are established after engine stop. The ECU is so programmed as to estimate a heat generation amount of the forward clutch at engine restart after idle stop, permit next idle stop when the heat generation amount is smaller than a first set value, permit next idle stop, after a lapse of a predetermined time, when the heat generation amount is equal to or greater than the first set value and equal to or smaller than a second set value which is greater than the first set value, and prohibit next idle stop when the heat generation amount is greater than the second set value.
