Patent number: 9758008Abstract: In an air conditioning system, a control unit controls an adjusting unit to adjust a ratio between an amount of a first part of introduced air passing through a heater core and an amount of a second part of the introduced air bypassing the heater core to a first ratio at which the amount of the first part of the introduced air decreases from a maximized amount of the first part of the introduced air according to an increase in temperature of the heater core by a warming unit. When a setting temperature for air conditioning is increased by an input unit, the control unit controls the adjusting unit to change the ratio from the first ratio to a second ratio at which the amount of the first part of the introduced air increases.Type: GrantFiled: April 22, 2013Date of Patent: September 12, 2017Assignee: SUZUKI MOTOR CORPORATIONInventors: Hideki Hashigaya, Kensuke Momose

Patent number: 9211777Abstract: A vehicle air-conditioning apparatus 10, installed in a vehicle having a no idling system (in which the engine stops rather than idling). The apparatus includes a blower fan 12 for sending air-conditioning air for temperature control in a vehicle compartment R to the vehicle compartment; a heater core 14 for heating the air-conditioning air by heat exchange with cooling water of an engine; and an automatic air controller 18 for executing temperature regulation control in the vehicle compartment by regulating an air-conditioning air volume to be heat exchanged with the heater core. The automatic air controller controls, on heating, during a no idling operation, driving of a blower fan so as to supply a determined air volume in response to the ambient air temperature detected by an ambient air temperature sensor 22a.Type: GrantFiled: June 25, 2012Date of Patent: December 15, 2015Assignee: SUZUKI MOTOR CORPORATIONInventors: Hideki Hashigaya, Naoki Fukumoto

Patent number: 9114686Abstract: There is provided an air conditioning system for a passenger compartment R of an electric vehicle having a rechargeable battery unit that is chargeable by supply of power from an external power source external to the vehicle. An air conditioner (AC) ECU 27 acquires a preparatory air conditioning time ? that is the time it takes to condition the interior air of the vehicle to a target interior air temperature 27T. An HEV controller 25 acquires from a quick charger 100 a charge time left 100R that is the time it takes until charge is completed and initiate preparatory air conditioning within the passenger compartment if the charge time left 100R is less than or equal to the preparatory air conditioning time ?.Type: GrantFiled: July 10, 2012Date of Patent: August 25, 2015Assignee: SUZUKI MOTOR CORPORATIONInventors: Hideki Hashigaya, Kensuke Momose

Patent number: 9090144Abstract: An air conditioning system for a passenger compartment of an electric vehicle has a battery unit that is chargeable by supply of electric power from an external power source. The system includes a charge-level detection section to detect a charge level of the battery unit and an HEV controller has an integrated control of the whole of an electric vehicle including an air conditioner. Before a preparatory air-conditioning operation for air conditioning in the passenger compartment during charge, the HEV controller grants permission to enter air conditioning in the passenger compartment if the battery charge level is greater than a predetermined level. The HEV controller adjusts an amount of electric power usable for air conditioning in the passenger compartment based on a change in the charge level.Type: GrantFiled: July 10, 2012Date of Patent: July 28, 2015Assignee: SUZUKI MOTOR CORPORATIONInventors: Kensuke Momose, Hideki Hashigaya
