Problems solved by technology

Park-in-drive (SID) automatic transmission stop-start applications suffer from similar problems, but the result is only a delay in starting the engine and delivering torque to the driver, and there is no risk of stalling

Embodiment Construction

[0022] refer to figure 1 , shows a motor vehicle 1 with an internal combustion engine 2 driving a flywheel with a starter ring gear 3 well known in the art. The motor vehicle 1 is of the micro-hybrid type, ie the engine 2 is controlled by an electronic controller to automatically stop and restart when certain predetermined conditions exist, thereby improving fuel economy and reducing emissions.

[0023] The motor vehicle 1 includes means for restarting the engine 2 while the engine is still spinning, should a driver change of mind event occur during engine shutdown. The device comprises a pneumatic motor 5 drivably connected to an engine 2 via an electronically controlled clutch 4 , a source of compressed air for the pneumatic motor 5 in the form of an air tank 6 , an electronically controlled valve 7 and an electronic control unit 9 .

[0024] It will be appreciated that the electronic control unit 9 will act as a stop-start controller for the engine 2 or it may be a stand-a...

Abstract

The invention discloses an apparatus for restarting an engine, wherein, if a driver's change of mind event occurs during an engine stop, the pneumatic motor (5) is activated to restart the engine (2) with minimal delay.

Description

technical field [0001] The present invention relates to starting of an internal combustion engine, and more particularly to restarting the engine in the event of a driver's change of mind during an engine stall. Background technique [0002] For manual transmission vehicles using a stop-in-neutral (SIN) stop-start strategy and conventional starters that are not permanently engaged, there is a potential problem in the event of a driver change of mind (CoM). A CoM occurs if the driver triggers a request to restart the engine during an engine shutdown. [0003] With a conventional starter, there will be a delay between the time the CoM event occurs and the time the starter is available to restart the engine because the starter pinion of the starter does not engage until the engine is stopped. This delay can result in a "kangaroo" or jerk start because the engine does not achieve sufficient speed before the driver has had time to engage the clutch and request torque, or, if the...
