Patent number: 8676353Abstract: In the control system having plural control devices that are connected to a network, and control objects different from each other, an engine control device, a meter control device, and an AT control device, which are second control devices store a control volume computation procedure for computing the control volume of a pre-determined control among controls made by the engine control device which is a first control device, therein. The engine control device compares the control volume related to the pre-determined control computed by the engine control device with the control volume related to the pre-determined control computed by the meter control device. If a comparison result is different, the engine control device again compares the control volume with the control volume related to the pre-determined control computed by the AT control device, and controls an object to be controlled by the engine control device according to the comparison result.Type: GrantFiled: August 25, 2011Date of Patent: March 18, 2014Assignee: Mitsubishi Electric CorporationInventors: Toshinori Matsui, Madoka Baba, Kiyohiro Morita

Publication number: 20120293003Abstract: Provided is a cell capacity adjusting device for reducing fluctuations in state of charge (SOC) among cells of a battery pack 101, which is formed by connecting a plurality of cells 111-116 in series, during suspension of operation of electrically-powered equipment whose main power source is the battery pack 101. From among the plurality of cells 111-116, one or a plurality of cells having a voltage value equal to or higher than a cell capacity adjustment target voltage are selected. By the selected cells, an intermittent operation unit 105, which operates even during the suspension of operation of the electrically-powered equipment, is caused to perform an intermittent operation. Through repetition of the intermittent operation, voltage values of the selected cells are decreased. Thus, fluctuations in state of charge (SOC) among cells are reduced without unnecessarily discharging battery stored energy of the battery pack 101.Type: ApplicationFiled: February 4, 2011Publication date: November 22, 2012Applicant: Mitsubishi Electric CorporationInventors: Koji Shimamura, Toru Morita, Toshinori Matsui

Patent number: 8031740Abstract: A transmitter node includes a first data transmission portion that transmits data in a first transmission time slot on a first transmission channel and a second data transmission portion that transmits the same transmission data from the first data transmission portion in a second transmission time slot on a second transmission channel that does not superimpose in time on the first transmission time slot. A receiver node includes a first data reception portion that receives data transmitted from the transmitter node in a first reception time slot superimposing in time on the first transmission time slot on the first transmission channel and a second data reception portion that receives transmission data transmitted from the second data transmission portion in a second reception time slot on the second transmission channel superimposing in time on the second transmission time slot. Data transmission and reception can be thus ensured even at a trouble.Type: GrantFiled: April 7, 2009Date of Patent: October 4, 2011Assignee: Mitsubishi Electric CorporationInventors: Toshinori Matsui, Madoka Baba, Takashi Kaneyama

Patent number: 7571033Abstract: System for detecting stability/instability of behavior of a motor vehicle upon occurrence of tire slip or lock. State of the motor vehicle is determined on the basis of an alignment torque (Ta) applied from a road and a side slip angle (?). By taking advantage of such torque/slip-angle characteristic that although the alignment torque is proportional to a side slip angle when the latter is small, the alignment torque becomes smaller as the side slip angle increases, a normal value is determined from a straight line slope and the side slip angle in a region where the latter is small. Unstable behavior of the motor vehicle is determined when deviation of actual measured value from the normal value increases. Further, unstable state is determined when the slope of the alignment torque for the slip angle departs significantly from that of approximate straight line slope.Type: GrantFiled: January 7, 2005Date of Patent: August 4, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroshi Fujioka, Takanori Matsunaga, Takashi Maeda, Toshinori Matsui, Masahiko Kurishige, Hideyuki Tanaka
