A vehicle idling stop control device has switches that detect an operation of opening a driver's door and an unbuckling of a driver's seat belt as disembarkation operations by a driver. When a disembarkation operation performed by the driver is detected during an idling stop, the idling stop is cancelled and the engine is restarted upon detecting a disembarkation operation performed by a driver during the idling stop. Also, restarting of the idling stop is prevented due to ending of the disembarkation operation performed by the driver until after the vehicle starts traveling. Thus, unnecessary automatic stopping and automatic restarting of the engine are thereby avoided when the vehicle sets off without the driver actually exiting the vehicle.

A vehicle apparatus has a controller, a first key reader disposed in a cabin of the vehicle, and a second key reader disposed external of the vehicle, such as on an auxiliary equipment. The controller is configured to actuate an engine control unit upon receipt of an authenticated signal. The controller is configured to receive a signal from the first key reader when the vehicle apparatus is operable in a first mode, and the controller is configured to receive a signal from the second key reader when the vehicle apparatus is operable in a second mode.

Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, following a first unsuccessful engine restart attempt, prompting a driver, via a human machine interface (HMI) to apply a brake pedal and upon application of the brake pedal, carrying out one or more restart attempts. If the driver does not apply the brake pedal within the threshold duration, the driver may be prompted to manually restart the engine.

Systems and methods for starting an internal combustion engine of a hybrid vehicle are presented. In one example, the internal combustion is started via closing a driveline disconnect clutch and limiting a torque output rate of an electric machine so that vehicle speed may increase continuously without decreasing during engine cranking and run-up periods.

In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, at which restarting is possible only by fuel injection. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started using a starter motor if the engine speed is less than the combustion recoverable rotational speed threshold. When there is a request to restart the engine in a brake ON state, the engine is not started by resuming fuel injection, but rotated and started using the starter motor.

The present invention relates to a method of controlling a vehicle. The method comprises stopping (12) an engine (2) of the vehicle (1) when a speed of the vehicle (1) is greater than or equal to a speed threshold, and inhibiting (17) starting of the engine (2) if the speed of the vehicle (1) falls below the speed threshold and a driver demand for braking force is less than or equal to a braking force threshold. Further aspects of the invention relate to a control system, a system and a vehicle.

In the case of restarting an internal combustion engine that has been automatically stopped during running, the internal combustion engine is restarted by combustion recovery starting when the rotation speed of the internal combustion engine under the input of a restart request is greater than or equal to a predetermined first rotation speed. In the case of restarting the internal combustion engine that has been automatically stopped during running, the internal combustion engine is restarted by cranking recovery starting when the rotation speed of the internal combustion engine under the input of the restart request is lower than the predetermined first rotation speed. The first rotation speed is set lower at the restart of the internal combustion engine in a sailing stop state than at the restart of the internal combustion engine in a coast stop state.

A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system includes: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.

A method for controlling a start of a vehicle using a controller includes: determining whether revolutions per minute (RPM) of an engine is within a reference range when start of the vehicle is requested; determining whether state data for controlling the vehicle satisfies a control condition for controlling a start of the vehicle when RPM of the engine is within the reference range; determining whether a position value of an accelerator pedal is less than or equal to a reference position value when the state data satisfies the control condition; determining whether a speed of the vehicle is greater than or equal to a reference speed when the position value of the accelerator pedal is less than or equal to the reference position value; and controlling a brake device when speed of the vehicle is greater than or equal to the reference speed.

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.
