  • Publication number: 20220089142
    Abstract: A vehicle drive route instruction system in a hybrid vehicle in which when it is judged that currently the vehicle is driving through the inside of the engine drive restriction zone where driving by the internal combustion engine is restricted, the internal combustion engine is made to stop operating, the electric motor is used to drive the vehicle, and the shortest route from the current position to the boundary of the inside of the engine drive restriction zone and the outside of the engine drive restriction zone is searched. When it is judged that the SOC amount will fall to the preset judgment standard when driving the vehicle through the searched shortest route from the current position to the boundary, an occupant of the vehicle is given information to guide the vehicle from the current position through the searched shortest route to the boundary.

  • Patent number: 10288031
    Abstract: A controller for an internal combustion engine includes a crank angle detector and an ECU. The ECU is configured to: (a) calculate a mass fraction burned; (b) acquire the crank angle, which is detected by the crank angle detector when the mass fraction burned reaches a predetermined mass fraction burned, as a specified crank angle; and (c) control at least one of an amount of fuel injected, an amount of intake air, or ignition energy on the basis of a first difference. The first difference is a difference between a first parameter and a second parameter. The first parameter is a crank angle period from an ignition time to the specified crank angle or a correlation value of the crank angle period. The second parameter is a target value of the crank angle period or a target value of the correlation value.

  • Patent number: 10156187
    Abstract: A reciprocating internal combustion engine includes an in-cylinder pressure sensor and a crank angle sensor. Data of calculated heat release amount in synchronization with crank angle is calculated using in-cylinder pressure after absolute pressure correction. An amount of heat release amount variation is calculated as a difference between a first calculated heat release amount at a first crank angle on an advanced side of TDC and a second calculated heat release amount at a second crank angle symmetrical about TDC. An actual heat release amount is estimated based on the amount of heat release amount variation calculated using, as the first crank angle, a crank angle on an advanced side of a combustion start point and using, as the second crank angle, a crank angle on a retarded side of a combustion end point.
