Patent number: 10910815Abstract: An electronic control unit having a self-diagnosis function is realized in which an operation processing section is capable of identifying not only the presence or absence of the occurrence of NG of disconnection, an earth fault, and a power fault, but also three states of NG, OK, and indetermination. Therefore, when a diagnosis opportunity is present, a mask signal maintains a state of Not Mask even if the mask signal is subsequently brought into a mask state. When an operation processing device requests a drive circuit for communication therewith, the mask signal is set to the state of Mask, and information stored in a register is cleared. Further, when the mask signal is in the state of Mask when the operation processing device performs communication with the drive circuit, the operation processing device is capable of identifying that an indeterminate state free of the opportunity of the diagnosis is present.Type: GrantFiled: March 26, 2018Date of Patent: February 2, 2021Assignee: Hitachi Automotive Systems, Ltd.Inventors: Takayasu Matsushita, Yoshihisa Fujii

Patent number: 9382891Abstract: An engine control apparatus includes an engine control unit that is configured to control a ring gear, a starting device and a pinion gear. The engine control unit is further configured to perform a control to engage the ring gear and pinion gear with each other in an idling stop state, and to control a pinion gear driver.

Publication number: 20160003182Abstract: A control device is provided which prevents a temperature increase within an ECU by suppressing heat generation in the ECU without using a new cooling device such as a blow fan. In one step, an open valve voltage target value is calculated. An open valve voltage is a voltage applied to a fuel injection valve when opening the fuel injection valve. As the number of times of the multi-stage injections increases, an opportunity to boost the open valve voltage increases, heat is generated in the open valve voltage boosting section, a temperature within the ECU excessively increases, and there is a concern that an electronic component within the ECU malfunctions or fails. Thus, a temperature sensor is provided on an inside of the ECU and if an ECU temperature is high, it is determined that heat is generated in the open valve voltage generating section and the open valve voltage target value is reduced.Type: ApplicationFiled: February 7, 2014Publication date: January 7, 2016Inventors: Yoshihisa FUJII, Takao FUKUDA, Masahiro TOYOHARA
