Abstract
The present application generally relates to a method and apparatus for application of a park hold assist system in a motor vehicle. In particular, the system is operative to receive an activation signal and to determine that the vehicle is in a park hold assist condition, such as inclined road surface, attached trailer or wheel rotation while transmission is in the park position. The system is operative to apply the hydraulic brakes in response to this condition thereby engaging a brake mechanism on all wheels.
