Problems solved by technology

This results in complete disengagement of the clutches and / or brakes within the transmission
These clutches and / or brakes can take time to fully re-engage when the engine is restarted, thus creating slippage and a delay between the engagement of the accelerator pedal or the release of the brakes and the movement of the vehicle
Also, there are situations where automatic engine stopping is undesirable, such as during idling or brief stops while the vehicle is still moving

Embodiment Construction

[0052] The following description is merely exemplary in nature and is not intended to limit the disclosure, its application, or uses.

[0053] refer to figure 1 , a motor vehicle is shown in the figure and is generally designated with the reference number 5 . Motor vehicle 5 is illustrated as a passenger car, but it should be appreciated that motor vehicle 5 may be any type of vehicle, such as a truck, van, or the like. Motor vehicle 5 includes an exemplary powertrain 10 . It should be appreciated at the outset that while a rear wheel drive powertrain is shown, motor vehicle 5 may also have a front wheel drive powertrain without departing from the scope of the present invention. The powertrain 10 generally includes an engine 12 interconnected with a transmission 14 .

[0054]Engine 12 may be a conventional internal combustion engine or an electric motor, or may be any other type of prime mover without departing from the scope of the present disclosure. The engine 12 provid...

Abstract

A system and method for controlling automatic stop-start of a motor vehicle is provided. The system and method is configured to enable an automatic stop-start mode of operation based on vehicle conditions. In addition, the system and method is configured to selectively actuate an accumulator to prime the transmission for a smooth restart.

Description

Technical field [0001] This public involves a system and method for controlling the automatic stop-starting-starting of the engine, and more specifically involved a system and method for the automatic stop-starting system and method to control the engine of vehicle conditions and accumulators. Background technique [0002] The statement in this section only provides background information related to this disclosure and can may not constitute existing technologies. [0003] The typical automatic transmission includes a hydraulic control system. In addition to other functions, the hydraulic control system is used to promote multiple torque transmission devices.These torque transmission devices can be such as friction clutch and brakes.The conventional hydraulic control system usually includes the main pump. The main pump provides a stamped fluid (such as oil) to provide solenoid (such as oil) in the valve and valve body.The main pump is driven by a motor vehicle engine.The valve an...
