Including Automatic Engine Stop Patents (Class 123/179.4)
  • Patent number: 10451021
    Abstract: In an information providing method and device for a vehicle, an engine of the vehicle is stopped automatically when a predetermined permission condition is satisfied in a state in which the vehicle is stopped by a brake operation executed by a driver. The driver is notified of support information for satisfying the permission condition when the permission condition is not satisfied in the state in which the vehicle is stopped by the brake operation. A vehicle stop keeping control generates a braking force capable of maintaining a vehicle stopped state even when the brake operation decreases. The notification of the support information is stopped when it is determined that the driver does not wish to automatically stop the engine in a state in which the support information is being notified and the vehicle stop keeping control is in operation.

  • Patent number: 10415529
    Abstract: There is provided a controller for a vehicle that can execute, while the vehicle is stationary or moving, control of automatically stopping an engine upon determining that automatic stop conditions are met, and automatically restarting the engine upon determining that automatic restart conditions are met while automatic engine stop is in effect. At a time of first engine restart in one trip, the controller diagnoses whether a system that automatically restarts the engine is normal or abnormal. The automatic stop conditions for in-motion automatic engine stop include automatic stop execution conditions that are set based on a state of the vehicle, and automatic stop permit conditions that are set based on a travel environment. The controller sets the automatic stop permit conditions such that determination criteria are more stringent as a cumulative number of times of in-motion automatic engine stop in one trip is smaller.

    Abstract: A vehicle control apparatus includes an electronic control unit. The electronic control unit is configured to perform feedback control of a motor such that a torque is output for stopping a crankshaft at a target angle. A first angle is used as the target angle during a first period from start of the feedback control to first detection of rotation of the crankshaft in a negative rotational direction for returning the crank angle. A second angle is used as the target angle during a second period from the lapse of the first period to detection of a changeover in a rotational direction of the crankshaft from the negative to a positive rotational direction. The electronic control unit is configured to return the target angle to the first angle at a first timing after the lapse of the second period.

    Abstract: In an information providing method for a vehicle, an engine is stopped automatically when a predetermined permission condition is satisfied in a state in which the vehicle is stopped by a brake operation executed by a driver. The permission condition is a brake operation amount of a brake having reached a predetermined brake operation amount. The driver is notified of support information prompting the driver to increase the brake operation amount when the permission condition is not satisfied after a predetermined time has elapsed since the vehicle was stopped. A braking force capable of maintaining a vehicle stop state is generated by a vehicle stop keeping control. The driver is notified of the support information when the brake operation amount decreases before the predetermined time has elapsed in a state in which the vehicle has been stopped by the brake operation and the vehicle stop keeping control is executed.

The controller is operable automatically to adjust an engine stop delay parameter in dependence on the value of at least one vehicle endurance parameter. The engine stop delay parameter corresponds to a period for which the engine of the vehicle remains switched on when it is determined that a condition exists allowing the engine to be switched off during the course of a drive cycle. The value of the endurance parameter is responsive to stop/start operations being performed during the course of a drive cycle. The controller is operable to adjust the engine stop delay parameter to prevent the value of the endurance parameter exceeding a prescribed maximum endurance value before a prescribed time period elapses.

    Abstract: When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion. The apparatus determines whether the start condition becomes satisfied based on a first start request owing to a driving operation by a driver of a vehicle on which the engine is mounted. When the start condition becomes satisfied based on the first start request, the control apparatus makes a maximum value of an engine generating torque by the first time combustion and/or a maximum torque of the engine generating torque by a second time combustion larger as compared to when the start condition becomes satisfied based on a second start request other than the first start request.

    Abstract: When a stop position of a piston resulting from the automatic stop is in a range that is on an advance side of a threshold in terms of crank angle, fuel injection is performed at beginning of the automatic restart-up in the cylinder that is in the intake stroke and an ignition is performed in a subsequent initial compression stroke in the same cylinder. When the stop position of the piston resulting is in a range that is on a retard side of the threshold in terms of crank angle, initial fuel injection is performed in the cylinder that next enters an intake stroke among the cylinders of the internal combustion engine after the beginning of automatic restart-up and initial ignition is performed in a subsequent compression stroke in the same cylinder. The threshold is determined in accordance with an amount of deviation of a crank angle.

  • Patent number: 9657657
    Abstract: A control device, which is applied to an in-vehicle internal combustion engine equipped with an intake valve variable timing mechanism that varies the valve timing for an intake valve, and which intermittently operates the in-vehicle internal combustion engine by automatically stopping/restarting the engine, wherein the electronic control unit does not permit the engine operation to be automatically stopped when the intake valve variable timing mechanism malfunctions at an operating position closer to the advanced angle than the operating position for the most retarded angle of the variable range for the valve timing of intake valve, and thus preventing increased engine vibration and misfires when the engine automatically restarts, which are caused by a malfunction of the variable valve mechanism.

  • Patent number: 9651015
    Abstract: A method for preventing a sudden start of an automatic transmission vehicle includes detecting data for determining whether a sudden start condition is satisfied; determining whether a shift stage is an N stage or a P stage when an engine runs. Whether the sudden start condition is satisfied is determined based on the data when the shift stage is the N stage or the P stage when the engine runs. An engine torque is limited below a predetermined torque, and a brake is operated when the sudden start condition is satisfied.

  • Patent number: 9599086
    Abstract: A method of controlling a fuel system includes determining the opening of a pressure relief valve and initiating a reseat strategy for the valve. The fuel system comprises a source of high pressure fuel and a pressure relief valve having at least one inlet fluidly coupled to the source of high pressure fuel and at least one outlet. The pressure relief valve has a closed position and at least one open position in which fuel is able to pass from the inlet to the outlet. The method comprises the steps of continuously measuring the pressure of the fuel in the fuel source, determining whether the pressure relief valve is in an open position, and generating an open signal if it is determined that the pressure relief valve is in an open position.
