  • Patent number: 11920530
    Abstract: A method for delaying cylinder reactivation in a vehicle includes identifying, by a controller, a request to exit a cylinder deactivation state. The controller determines if the request is due to a transient condition. If the request is due to the transient condition, the controller analyzes at least one of the transient condition and a condition of the vehicle. The controller determines a first adjustment to the vehicle based on analyzing at least one of the transient condition and the condition of the vehicle. The first adjustment is configured to mitigate the transient condition. The controller implements the first adjustment.
