    Abstract: Where performing a main injection, and a sub-injection that injects a minute amount of fuel in a short region of driving time, a check is conducted to determine whether or not the minute amount of fuel is injected accurately. In a specific cycle at a time of cold starting when catalyst warm-up control is performed, the main injection is omitted and a checking injection corresponding to a sub-injection is performed. Injection conditions of an in-cylinder injection valve are made uniform between the checking injection and the sub-injection. A fuel amount that is actually injected from the in-cylinder injection valve in the specific cycle is calculated based on an air-fuel ratio of exhaust gas discharged from an engine and an in-cylinder air amount, and is compared with a fuel amount that theoretically should be injected from the in-cylinder injection valve.

  • Patent number: 9765500
    Abstract: A power transmission device of a work vehicle includes a generator, a motor, and an energy storage unit. The energy storage unit stores electricity generated by the generator. A forward/backward travel switch operation device receives an instruction for forward or backward travel from an operator. A vehicle speed detection unit detects the speed of the vehicle. A control unit includes an energy management requirement determination unit. The energy management requirement determination unit determines, on the basis of the difference between a target electricity storage amount and a current electricity storage amount in the energy storage unit, the energy management required power required by the power transmission device for charging the energy storage unit. The energy management requirement determination unit increases the target electricity storage amount when a first travel direction according to the instruction and a second travel direction determined from the vehicle speed are different.

  • Patent number: 9745905
    Abstract: Methods and arrangements are described for controlling transitions between firing fractions during skip fire operation of an engine in order to help smooth the transitions. Generally, firing fractions transitions are implemented gradually, preferably in a manner that relatively closely tracks manifold filling dynamics. In some embodiments, the commanded firing fraction is altered each firing opportunity. Another approach contemplates altering the commanded firing fraction by substantially the same amount each firing opportunity for at least a portion of the transition. These approaches work particularly well when the commanded firing fraction is provided to a skip fire controller that includes an accumulator functionality that tracks the portion of a firing that has been requested, but not delivered, or vice versa.

  • Patent number: 9726531
    Abstract: Provided is a cylinder intake air amount estimation apparatus for an internal combustion engine, which is capable of highly precisely calculating a cylinder intake air amount based on an AFS intake air amount in a control system for an engine including a supercharger. A cylinder intake air amount calculation part calculates the cylinder intake air amount based on an intake opening intake air amount by using a physical model of an intake system derived based on a volume efficiency acquired by considering an intake manifold as a reference, which is a volume efficiency of air entering a cylinder from the intake manifold, a virtual intake manifold volume, and a stroke volume per cylinder, the physical model being adapted to the control system for an engine including a supercharger.

  • Patent number: 9719435
    Abstract: Techniques for measuring cylinder pressure include receiving an analog cylinder pressure signal indicative of pressure in a cylinder of an engine and an angular position signal indicative of an angular position of the engine. The analog cylinder pressure signal is converted to a digital cylinder pressure signal by (i) windowing the analog cylinder pressure signal in the angle-domain using the angular position signal and (ii) sampling the windowed analog cylinder pressure signal in the time-domain, and the digital cylinder pressure signal is filtered in the time-domain to obtain a filtered digital cylinder pressure signal. A measured pressure in the angle domain is obtained by sampling the filtered digital cylinder pressure signal using the angular position signal, and operation of the engine is controlled using the measured cylinder pressure.

  • Patent number: 9701287
    Abstract: A device and a method for determining an absolute angular position of a wheel of a vehicle. A wheel unit is mounted on the wheel side and configured to determine data which permit a reference limb of the wheel, and to wirelessly transmit the acquired data. A receiver unit is mounted on the vehicle side and receives the data of the wheel unit. A reference limb-determining device determines the reference limb of the wheel on the basis of the received data. A measuring device generates, in each case, one signal when the wheel rotates by a previously determined angle, and a counting device counts the signals generated by the measuring device. An angle-determining device determines an absolute angular position of the wheel on the basis of the signals counted by the counting device, and on the basis of the specific reference limb.

  • Patent number: 9664145
    Abstract: A method, comprising: indicating a leak of a first diameter on a canister side of a fuel system following applying a vacuum to the fuel system with a fuel tank isolation valve closed; and indicating a leak of a second diameter on a fuel tank side of the fuel system, based on a vacuum decay in an isolated fuel tank following applying a vacuum to the fuel system with the fuel tank isolation valve open. In this way, an evaporative leak check module with a single reference orifice may be used to determine leaks of multiple sizes in multiple sectors of a fuel system. This may allow current production models to meet more stringent emissions regulations in the future.
