Patent number: 7710068Abstract: A power supply control apparatus for controlling an electric generator of a vehicle limits the rate of change of a power supply voltage to a predetermined variation rate range, when the change is caused by operations to control the charge condition of the vehicle battery, and controls the generated power to match the drive torque applied by the engine to the generator. When the electrical load demand changes, the generated power is controlled to limit a resultant momentary change in the power supply voltage caused by an engine response delay, while minimizing a resultant momentary amount of engine speed variation.Type: GrantFiled: June 6, 2007Date of Patent: May 4, 2010Assignee: Denso CorporationInventors: Keisuke Tani, Kazuyoshi Obayashi, Takashi Senda, Yukihiro Yamashita, Daisuke Kuroda

Patent number: 7571712Abstract: A base engine torque generated with an estimated intake air amount is estimated. An engine torque is corrected by correcting an ignition timing based on a difference between a required engine torque and the base engine torque. A torque correction amount is calculated based on a correction amount of the ignition timing. An actual engine torque is estimated based on the calculated torque correction amount and the base engine torque. A permitted component driving torque is a difference between the actual engine torque and the required vehicle driving torque. A component is controlled based on the permitted component driving torque.Type: GrantFiled: January 18, 2008Date of Patent: August 11, 2009Assignee: Denso CorporationInventors: Daisuke Kuroda, Yukihiro Yamashita, Keisuke Tani, Kazuyoshi Obayashi, Katsunori Tanaka
