摘要： A coast stop vehicle includes a hydraulic pressure supplying unit which supplies a hydraulic pressure to the transmission while the engine is stopped, a coast stop start condition judging unit which judges whether or not a coast stop start condition holds, a coast stop control unit which stops the engine when the coast stop start condition is judged to hold by the coast stop start condition judging unit and starts the engine when receiving an acceleration request from a driver during the coast stop, a transmission control unit which causes a downshift of the transmission when receiving the acceleration request from the driver during the coast stop, and a hydraulic control unit which supplies the hydraulic pressure to an after-shift frictional engagement element which realizes a gear position after the downshift of the transmission during the coast stop.

摘要： A coast stop vehicle includes a variator which continuously changes a speed ratio by changing a winding diameter of a belt mounted on pulleys, a sub-transmission mechanism connected in series with the variator and shifting discrete gear positions by changing engaged states of a plurality of frictional engagement elements, and a coast stop unit which stops the rotation of the drive power source and releases the engaged frictional engagement element when the coast stop condition holds during travel. The coast stop unit includes a coast stop prohibiting unit which prohibits the coast stop regardless of the coast stop condition when it is predicted at the time of determining whether or not the coast stop condition holds that a belt tightening force of the pulley falls below an engaging force of the frictional engagement element in the engaged state by the execution of the coast stop.

摘要： A controller actuates an electrical oil pump when an idle stop condition or a coast stop condition holds and causes the actuation of the electrical oil pump to continue without being stopped until an accelerated state of a vehicle or a driver's intention to accelerate is determined even if the idle stop condition and the coast stop condition no longer holds thereafter.
