Assistance Changes During Auto Stop/Start Functions
This feature actively controls the driver's steering torque feedback during the engine auto stopping and starting activities. It integrates the main steering assistance feature with micro hybrid or enhanced starter motor powertrain events, ensuring smooth, progressive, yet timely decreases and increases in power assistance. It is also designed to remove unwanted steering wheel movement during these events, which are not directly instigated by the driver.
For vehicles equipped with automatic transmission, a reduced level of assist is maintained throughout the auto stop and the driver will be able to request an engine restart by turning the steering wheel. The restart request in this case is based on the amount of current drawn by the steering during the auto stop.
For vehicles equipped with manual transmission, assist is reduced completely during an auto stop and the driver will not be able to request the engine to restart through use of the steering wheel.
