Vehicle and method of controlling an engine auto-stop and restart

摘要

A vehicle includes an engine, a manual transmission having a clutch, and a controller. The controller is configured to, in response to receiving a signal indicative of a deceleration event initiated by the controller when the vehicle is operating with the clutch engaged, command the engine to shut down before an engine stall threshold to prevent a stall. A method of controlling a vehicle having an engine and a manual transmission with a clutch includes, in response to receiving a signal indicative of a deceleration event above a threshold value when the vehicle is operating with the clutch engaged, shutting down the engine before an engine stall threshold to prevent a stall.

1. A method of controlling a vehicle having an engine, a manual transmission with a clutch, a collision mitigation system, and a user interface, the method comprising:
decelerating the vehicle in response to a first signal indicative of a potential collision event; reducing a load on the engine by a controlled torque reduction; auto-stopping the engine when the clutch is engaged when the engine reaches a speed at an offset above an engine stall threshold; commanding the user interface to provide a message with directions for a user input to restart the engine in response to a second signal indicative of the potential collision event ending, the user input including shifting the transmission to neutral and activating a clutch pedal; and auto-starting the engine in response to a third signal indicative of the user input.
