摘要： An engine start-stop control system for an automotive vehicle includes a first step for supplying current to a solenoid of a magnet switch of a starter at 100% duty ratio until a first predetermined time passes, a second step for supplying current to the solenoid at a duty ratio that is less than 100% after the first predetermined period passes until a second predetermined period passes, and a third step for supplying current to the solenoid at 100% duty ratio after the second predetermined period passes until a third predetermined period passes. Therefore, a pinion of the starter reaches a ring gear of the engine in a short time and engages the ring gear with a moderate impacting shock, thereby preventing the pinion and the ring gear from being damaged.

摘要： A hybrid vehicle is provided with an engine (2), a first motor (1) for starting the engine (2), a generator (1) for driving the engine (2), drive wheels (8) connected to the engine (2) via a clutch (3), and a second motor (4) for driving the drive wheels (8). A battery (15) connected to the first motor (1), second motor (4) and generator (1) is further provided. A control device which controls the engine startup by the first motor (1) comprises a sensor (27) which detects a rotation speed of the engine (2), a sensor (26) which detects the charge amount of the battery (15), a power controller (11) which varies the current supplied to the first motor (1) from the battery (15) according to a signal, and a microprocessor (16) which outputs the signal. The microprocessor (16) calculates a target output torque of the first motor (1) according to the charge amount of the battery (15). When the rotation speed of the engine (2) is less than a predetermined target rotation speed, the signal is set so that the output torque of the first motor (1) coincides with a predetermined output torque, and after the rotation speed of the engine (2) reaches the predetermined target rotation speed, the signal is set so that the rotation speed of the engine (2) is maintained at the predetermined target rotation speed.

摘要： An enhanced engine starter system controls an air turbine starter at the startup of operation of a turbine engine. The engine starter system includes an air turbine starter (ATS) that operates in accordance with more than one speed/torque curve during the startup procedure. A controller commands the starter control valve to provide a regulated pressure to the ATS in accordance with a first speed/torque curve to initiate the gas turbine engine startup without exceeding a maximum or design limiting torque. Overall duration of the startup procedure is reduced by the controller subsequently operating the ATS in accordance with a second speed/torque curve having a higher operational pressure once the ATS reaches a predetermined transition speed. The torque at the predetermined transition speed on the higher pressure second curve remains less than the design limiting torque, but provides a higher torque as compared to the first speed/torque curve to reduce the duration of the startup procedure.

摘要： An ECU is applied to an engine system including an engine and an MG. The ECU determines whether or not a piston is located at a position, at which compression reactive force is received, at a time point at which engine speed reaches zero after combustion of the engine is stopped. Further, in a case where the ECU determines that the piston is located at the position at which compression reactive force is received, the ECU stops the piston by applying positive torque on a positive rotation side to a crank shaft by the MG.

摘要： An engine starting apparatus is provided which is equipped with a starter, an inrush current reducer, and a starter mode switch. The inrush current reducer works to reduce an inrush current flowing through an electric motor installed in the starter when the electric motor is energized. The starter mode switch works to change a starter characteristic that is an output characteristic of the starter continuously or selectively at least between a low-torque/high-speed mode and a high-torque/low-speed mode. The starter mode switch places the starter in the high-torque/low-speed mode at least at a time when a piston of the engine is passing a top dead center, and the engine friction has been just maximized for the first time after the starter is actuated to crank the engine. This shortens a period of time required to start up the engine without sacrificing beneficial effects offered by the inrush current reducer.

摘要： A method for controlling starting of a Liquefied Petroleum Injection (LPI) engine of a mild hybrid electric vehicle includes driving a fuel pump when a first node of an ignition switch is selected, performing an engine cranking operation by driving a Mild Hybrid Starter & Generator (MHSG) when a second node of the ignition switch is selected, determining whether a cranking completion condition is satisfied while performing the engine cranking operation, comparing a pressure of a Liquefied Petroleum Gas (LPG) fuel with a target pressure, and controlling the MHSG to generate a torque corresponding to an idle torque of the LPI engine when the pressure of the LPG fuel is less than the target pressure.

摘要： A control apparatus for an internal combustion engine is provided which works to control an electric motor to start the engine through a belt transmission system. The control apparatus restricts rotation of the electric motor so as to keep a speed of the electric motor below a speed at which the electric motor is capable of producing a maximum torque until a given period of time passes since the electric motor is actuated to start in the motor mode. This enables the electric motor to generate the maximum torque when it is required to crank the engine.
