Methods and systems are provided for an engine. In one example, a method of operating an engine of a vehicle, the vehicle comprising a brake pedal, a clutch pedal and a transmission having a neutral position and at least one in-gear position, comprises starting the engine if either the brake pedal of the vehicle is released or the transmission has been in neutral for a predetermined period of time, and the clutch pedal of the vehicle is depressed concurrently with the transmission being moved out of the neutral position into an in-gear position.

Methods and systems for an engine

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.

Stop-in-gear auto-start control

Systems and methods are provided for a vehicle including a start-stop system configured to shut down and restart an engine of the vehicle automatically based on a brake value of a brake system. In one example, the method may include determining a first threshold brake value as a first function of a gradient of a surface on which the vehicle is positioned, determining a second threshold brake value as a second function of the gradient, wherein a difference between the first and second threshold brake values varies as a function of the gradient, shut down the engine when the brake value exceeds the first threshold brake value, and restart the engine when the brake value drops below the second threshold brake value. In this way, an incidence of inadvertent engine shut downs and restarts when the vehicle is stopped on an incline may be decreased.

Start-stop system

The present disclosure describes systems and methods for controlling the speed of a vehicle comprising: during a pulse phase of cruise control, applying engine torque to raise speed, the amount and duration of which being responsive to engine speed; and during a glide phase of cruise control, discontinuing engine combustion. In this way cruise control may maintain a mean speed equivalent to a desired, threshold speed while reducing fuel consumption, and NVH effects felt by the end user compared to traditional cruise control methods.

Vehicle speed control apparatus and method

A method of operating a vehicle powertrain, includes: sensing a vehicle speed; selecting a plurality of control strategies; activating one of the plurality of control strategies, the control strategy including: (i) operating the vehicle in a stationary start-stop mode when the vehicle speed is below a first threshold; and (ii) operating the vehicle in a rolling stationary start-stop mode when the vehicle speed is above the first threshold but below a second threshold.

Method for operating a vehicle powertrain

A system and method for selectively opening a drivetrain of a vehicle is described. In one example, an electrically operated clutch is opened during selected driving conditions to conserve kinetic energy of the vehicle. The method may reduce fuel consumption during selected conditions.
