Patent number: 9975398Abstract: A front-seat air conditioner and a rear-seat air conditioner, which are independent from each other, are provided. An engine is automatically stopped under preset stop conditions. When the engine is automatically stopped in a case in which the number of passengers is a specified preset number (five, for example) or larger during heating, the operation of the rear-seat air conditioner is stopped (reduction of power consumption) and the operation of the front-seat air conditioner is continued (prevention of windshield glass from being fogged). Thereby, the windshield glass can be prevented from being fogged during the engine's automatic stop, reducing the power consumption of air conditioning.Type: GrantFiled: May 13, 2015Date of Patent: May 22, 2018Assignee: MAZDA MOTOR CORPORATIONInventors: Kazuhiro Miyagawa, Shinobu Kato, Naoki Takata

Patent number: 9610826Abstract: A blower fan is driven, and conditioning air flows down through an evaporator and then is supplied into a vehicle compartment. An idling-stop condition in a roof-open state is set to make an idling stop to be relatively easily attained, compared to a roof-closed state, so that a fuel economy can be improved. When an outside-air temperature is a specified temperature or higher or a solar-radiation intensity is a specified degree or greater at an engine's automatic stop, the blower fan is driven, so that the conditioning air is supplied toward a passenger in a manner of an electric fan. The evaporator through which the conditioning air flows down is sufficiently cool at the timing right after the automatic stop of the engine. Accordingly, it is preferable to configure such that the sufficiently-cooled conditioning air is supplied for a properly-long period of time.Type: GrantFiled: February 23, 2015Date of Patent: April 4, 2017Assignee: Mazda Motor CorporationInventors: Naoki Takata, Kazuhiro Miyagawa, Shinobu Kato, Shinshi Kajimoto
