Patent number: 10167839Abstract: The ignition control device includes a spark plug that includes a first electrode and a second electrode disposed so as to oppose each other, an ignition coil that includes a plurality of sets of a primary coil and a secondary coil, generates a high voltage in the secondary coil by energizing or interrupting a primary current supplied to the primary coil, and applies the generated high voltage to the first electrode, and a control unit that, in a case where a plurality of the primary coils are driven during a single ignition process, temporarily stops energization of a primary current supplied to a second primary coil when a primary current supplied to a first primary coil is interrupted, and re-energizes the primary current supplied to the second primary coil following the elapse of an energization stoppage period.Type: GrantFiled: October 12, 2016Date of Patent: January 1, 2019Assignee: Mitsubishi Electric CorporationInventors: Takahiko Inada, Takahiro Enomoto

Patent number: 9870774Abstract: A vehicular apparatus is provided. In the vehicular apparatus, a first controller is disposed on a first board and a second controller is disposed on a second board which is exchangeable with respect to the first board. An AD converter performs A/D conversion of first and second speech data. A switch disposed on the first board is switchable between a first connection state in which the switch outputs the first speech data inputted from the A/D converter and a second connection state in which the switch outputs a sound data different from each of the first and second speech data. A switch controller controls the switch so that the switch is in the second connection state when the second controller performs speech recognition of the second speech data.Type: GrantFiled: August 25, 2014Date of Patent: January 16, 2018Assignee: DENSO CORPORATIONInventors: Takayuki Nishiwaki, Takahiro Enomoto

Patent number: 9605643Abstract: There is provided a leakage detection apparatus that can accurately detect a leakage condition in an internal combustion engine having a cylinder resting function. An ignition plug provided in the combustion chamber of a cylinder is made to generate an ignition signal at least once when based on an instruction from a cylinder resting control unit, a fuel injection valve and a valve driving mechanism are stopping the operation thereof; the leakage condition of the ignition plug is detected based on an output signal generated by an ion current detection circuit at a timing other than the timing when ignition discharge is caused.Type: GrantFiled: April 6, 2015Date of Patent: March 28, 2017Assignee: Mitsubishi Electric CorporationInventors: Takahiko Inada, Takahiro Enomoto, Yuhei Matsushima, Takeshi Koda

Patent number: 9382852Abstract: Provided is a control device for an internal combustion engine having a cylinder resting mechanism, capable of accurately detecting an intake/exhaust valve state and therefore serving to solve problems of fuel depletion and environmental conservation. The control device includes: ignition means 2 including high voltage means 202 for causing ignition discharge on an ignition plug based on an ignition signal, and an ignition discharge parameter detection circuit 203 for detecting a parameter indicating a state of the ignition discharge; and valve state determination means 206 for determining a valve operation state of an intake/exhaust valve based on at least one of an ignition discharge duration, ignition insulation breakdown voltage, and ignition discharge maintaining voltage detected based on an output signal from the ignition discharge parameter detection circuit 203. Operation of cylinder resting control means 207 is controlled based on a determination result by the valve state determination means 206.Type: GrantFiled: July 17, 2014Date of Patent: July 5, 2016Assignee: Mitsubishi Electric CorporationInventors: Takahiko Inada, Takahiro Enomoto, Yuhei Matsushima
