Patent number: 11018617Abstract: Provided is a rotation angle detection device, including: a rotation angle sensor; an input circuit configured to output a rotation angle signal and an abnormality signal; a calculation processing unit con tired to calculate a rotation angle calculation value and a rotation speed calculation value based on a rotation angle detection value at a predetermined preset calculation timing; and a rotation angle estimation processing unit configured to calculate a rotation angle estimation value after the calculation timing based on the rotation angle calculation value and the rotation speed calculation value. When the abnormality signal is received, the calculation processing unit calculates the rotation angle calculation value and the rotation speed calculation value based on the rotation angle estimation value, in place of the rotation angle detection value.Type: GrantFiled: May 24, 2017Date of Patent: May 25, 2021Assignee: Mitsubishi Electric CorporationInventors: Hayato Kamizawa, Kiyohiro Morita, Michitaka Fujiwara

Patent number: 9493167Abstract: Before a communication control device ECU falls into a sleep state or a power-off state, a substitution request is transmitted to an ECU, among substitute candidate devices ECU to ECU, that is determined by a substitute transmission acceptability determining unit as being capable of taking over the communication control device. A substitution-capable processing load quantity, a substitution-capable process importance level, or a failure determination result of each of the ECUs is used as determination criteria when the substitute transmission acceptability determining unit of the ECU determines a substitute device, and the determination is carried out in an order that takes into consideration the process importance level of each of the ECUs during travelling or at a standstill, to prevent failures in a network or abnormal behaviors of a vehicle.Type: GrantFiled: December 19, 2014Date of Patent: November 15, 2016Assignee: Mitsubishi Electric CorporationInventors: Hiroshi Okuyama, Toru Morita, Toshinori Matsui, Madoka Baba, Kiyohiro Morita

Patent number: 8688241Abstract: Provided is a control system capable of reducing cost while securing reliability of original processing of a microcomputer. An engine control device and a meter control device each store a control amount calculating procedure for calculating a control amount regarding a significant control to be performed on the control target of the engine control device. The engine control device compares a control amount regarding the significant control calculated by the engine control device, and a control amount regarding the significant control calculated by the meter control device, to thereby control the control target of the engine control device based on a result of the comparison.Type: GrantFiled: September 28, 2012Date of Patent: April 1, 2014Assignee: Mitsubishi Electric CorporationInventors: Toshinori Matsui, Kiyohiro Morita, Madoka Baba, Toru Morita

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
