  • Patent number: 9151242
    Abstract: A vehicle has an engine as a driving source. The vehicle has a charge system which generates electric power by using a part of rotational output of an engine, and charges a battery by the generated electric power. Optimal shaft efficiency points are combinations of revolution speed and torque of the engine for maximizing the shaft efficiency. Optimal shaft efficiency line passes through the optimal shaft efficiency points for each engine output level. Warming-up operation line is defined by shifting the optimal shaft output efficiency line to a side to increase heat loss. An engine controller stores the lines. The engine controller performs a warming-up operation by operating the engine at a revolution speed and a torque on the warming-up operation line. The engine controller controls the battery to reduce possibilities of a full charge at a next warming-up.

  • Patent number: 9133811
    Abstract: The internal combustion engine (1) has a throttle (23) for controlling an intake air amount and performs start-up through cranking. As the cranking is initiated, an atmospheric pressure is detected and an initial opening is set accordingly. The controller (31) controls the throttle (23) to the initial opening when the cranking is initiated, and controls the throttle to start to increase the throttle opening from the initial opening at a predetermined timing after the cranking initiation. By setting the initial opening based on one or both of the atmospheric pressure and the temperature at the time of cranking initiation, the intake negative pressure and the intake air amount are optimized.

  • Patent number: 9026344
    Abstract: At the time of an engine start while the vehicle is driving, when a required vehicle driving force (TRQ) is smaller than or equal to a predetermined value (TRQth), an electronic control unit (20) estimates that the degree of deformation of a mount (11) is smaller than or equal to a predetermined degree and sets a second-cycle fuel injection amount (Q2) so as to be larger than a first-cycle fuel injection amount (Q1) at the time of the engine start. On the other hand, when the required vehicle driving force (TRQ) is larger than the predetermined value (TRQth), the electronic control unit (20) estimates that the degree of deformation of the mount (11) is larger than the predetermined degree and sets the first-cycle fuel injection amount (Q1) so as to be larger than the second-cycle fuel injection amount (Q2) at the time of the engine start.

  • Patent number: 9022002
    Abstract: A method to start operation of an internal combustion engine of a hybrid powertrain includes initiating rotation of a crankshaft of the engine with at least one electric machine in accordance with a first ramping profile until a first predetermined speed is achieved in response to an engine start event during a cold start condition. Engine speed is monitored and the engine is fired while controlling the engine speed to maintain the first predetermined speed with the at least one electric machine. The first ramping profile is adjusted at a rate corresponding to an estimated rate at which the engine speed is increasing during the engine firing. When at least one predetermined combustion quality parameter is achieved, the engine speed is controlled in accordance with a second ramping profile until a second predetermined speed is achieved based on controlling combustion parameters of the engine.

  • Patent number: 9020740
    Abstract: A system includes a sump, a pump having a steady-state speed, a fluid component that receives the fluid from the fluid pump, and a controller. The controller detects a soak condition of the system in which the pump load is low as fluid is moved into vacated fluid passages. The steady-state speed of the pump is temporarily increased by adding a calibrated overspeed value to the steady-state speed, for a calibrated duration. The controller reduces the pump speed to the steady-state speed after the calibrated duration has elapsed. A method includes detecting the soak condition and temporarily increasing the steady-state speed via the controller by adding the calibrated overspeed value to the steady-state speed, for a calibrated duration, when the soak condition is detected. A control system includes a processor and storage medium having instructions embodying the method, with detection of the soak condition provided via measurement of fluid temperature.
