Idle stop-start control system

The utility model discloses an idle stop-start control system. The idle stop-start control system comprises an engine, an ECU relay, a control chip, an ECU, a first generator, a first relay, a super-capacitor, a storage battery, a second relay, a starter motor, a starting relay, a third relay, a fourth relay, a clutch, a belt wheel, a one-way bearing, an inertia flywheel, a bearing, a second generator, a fifth relay and a sixth relay. The super-capacitor capable of directly supplying power to the starter motor is additionally arranged, so that most of the current is provided by the super-capacitor when the starter motor is started, it is avoided that the discharge current of the storage battery is excessively large when the super-capacitor supplies the current, and service life of the storage battery is prolonged; the second generator is additionally arranged and can be connected with the one-way bearing through a belt of the belt wheel, sliding energy can be effectively recovered when an automobile slides in a neutral gear mode, the recovered sliding energy is preferentially used for charging the super-capacitor, and waste of the sliding energy is reduced. The idle stop-start control system can be widely applied to the field of automobiles.
