    Abstract: A dual pump smart control system. The operating time and the number of simultaneous operations are analyzed and compared with a reference time and a reference number, so that a controller determines whether or not the operation is normal. Afterwards, the driving of a first pump and the driving of a second pump are differentially controlled depending on whether or not the operation is determined to be normal by the controller. Thus, a malfunction caused by the concentration of load at a specific pump is prevented. Accordingly, the dual pump smart control system precisely controls the driving of the dual pumps and enables the pumps to operate efficiently.

  • Patent number: 11441670
    Abstract: Because an EOP starts operating from when a decrease in discharge flow rate of an MOP is predicted or detected, a PL actual pressure that should be obtained with a PL command pressure set to a value for a required transmission torque is more easily maintained even when the discharge flow rate of the MOP becomes insufficient. After a lapse of a predetermined period of time from the start of operation of the EOP, the PL command pressure is temporarily set to a value higher than the value for the required transmission torque, and a regulator valve is controlled to operate to close a drain port. Therefore, the operation of the EOP in a high PL actual pressure is reduced, and a delay in response of a pressure regulating operation of the regulator valve in the process of reduction of the discharge flow rate of the MOP is reduced.

When a start request for an internal combustion engine is issued, the on-board controller executes an engine start process that sets a clutch mechanism to an engagement state, which engages an output shaft of the internal combustion engine with an output shaft of the electric motor, and drives the electric motor to perform cranking. When a state in which the clutch mechanism is maintained immediately before the engagement state is defined as an engagement preparation state, the on-board controller executes a preparation process that applies hydraulic pressure to the clutch mechanism during execution of the torque reduction process so that the clutch mechanism is set to the engagement preparation state.

  • Patent number: 11242045
    Abstract: There is provided a hybrid vehicle that suppresses the driver from feeling slow. At the time of a predetermined request that requires fuel injection of an engine in the state of motoring the engine under fuel cutting by a first motor at a rotation speed that is higher than an upper limit rotation speed during fuel injection of the engine, the hybrid vehicle waits until the rotation speed of the engine becomes equal to or lower than the upper limit rotation speed and then starts fuel injection of the engine. At the time of the predetermined request, the hybrid vehicle causes the rotation speed of the engine to be decreased by the first motor until the rotation speed of the engine becomes equal to or lower than the upper limit rotation speed.

  • Patent number: 11167748
    Abstract: A method for exiting from a recuperation phase in a parallel hybrid vehicle includes, in a first step, the vehicle is in a recuperation phase, started by means of a trigger, with a predefined recuperation driving demand, and, in a second step, the electric machine is brought to an increased rotational speed during the recuperation phase. In a third step, a phase for departing from the recuperation phase is started by means of a trigger, wherein, in this phase, the internal combustion engine is made available for coupling to the electric machine, such that a target rotational speed determined between the internal combustion engine to be connected and the electric machine for the connection to the transmission input is set, and in parallel, by means of an upshift, a highest possible gear ratio for the connection to the drivetrain is set, in order to satisfy a present driving demand. In a fourth step, the departure from the recuperation phase is completed.
