Abstract: Example embodiments described in this disclosure are generally directed to the use of a multi-zone geofence for key-free vehicle operations management. The multi-zone geofence may include a first zone where vehicles can be operated without the use of keys or key fobs, and a second zone surrounding the first zone where a first set of functional restrictions are imposed upon the vehicles. The first set of functional restrictions can include an upper speed limit that is automatically imposed upon a vehicle. The multi-zone geofence can include additional zones having functional restrictions, such as a third zone surrounding the second zone wherein key-free vehicle operations are permitted with a second set of restrictions. The second set of restrictions may include a directional speed feature involving an automatic speed reduction upon a vehicle travelling towards a periphery of the third zone and lifting the speed reduction if the vehicle turns back.

Abstract: Systems and methods for cooling an internal combustion engine via flowing air through the internal combustion engine during select conditions are presented. In one example, lift of intake and/or exhaust poppet valves may be adjusted as a function of engine temperature. In addition, opening and closing timings of intake and exhaust poppet valves may be adjusted as a function of engine temperature.

Abstract: Systems and methods for operating an engine with deactivating and non-deactivating valves is presented. In one example, the engine may include non-deactivating intake valves, deactivating intake valves, and only non-deactivating exhaust valves. The non-deactivating exhaust valves may operate to open and close during an engine cycle while deactivating intake valves remain closed during the engine cycle to prevent air flow through selected engine cylinders.

Abstract: Systems and methods for operating an engine and a torque converter are presented. In one example, slip of a torque converter is adjusted via at least partially closing or opening a torque converter clutch in response to vehicle vibration. The vehicle vibration may be based on road surface conditions and an actual total number of operating cylinders of the engine.

Abstract: Systems and methods for operating an engine with deactivating and non-deactivating valves are presented. In one example, an estimate of an amount of oil that may intrude into a deactivated cylinder is made. The deactivated cylinder may be reactivated in response to the amount of oil estimated to be in the deactivated cylinder.

Abstract: Systems and methods for determining when one or more cylinders of an engine may be activated or deactivated are presented. In one example, an actual total number of active cylinder modes may be increased in response to engine speed and load. Further, dimensions of an engine cylinder mode region of an engine cylinder activation may be adjusted responsive to a change in mass of a vehicle.

Abstract: Methods and systems are provided for adjusting noise, vibration, and harshness (NVH) limits for a vehicle based on a number of occupants in the vehicle. In one example, a method may include responsive to detecting zero occupants, reducing NVH constraints for operating the vehicle and adjusting one or more vehicle operating parameters based on the reduced NVH constraints.

Abstract: Systems and methods for operating an engine that includes two throttles that are arranged in parallel to deliver air into a single intake manifold are described. In one example, a first throttle is opened before a second throttle during a first condition and the second throttle is opened before the first throttle during a second condition. The throttles may be operated in this way to ensure even operation of the throttles.

Abstract: Systems and methods for activating and deactivating cylinders of an engine that may activate and deactivate one cylinder independent of other cylinders are presented. In one example, an engine cylinder firing fraction and a remainder value that is based on the engine cylinder firing fraction are a basis for activating and deactivating engine cylinders. The systems and methods also provide for transitioning between different cylinder firing fractions.

Abstract: Systems and methods for operating an engine with deactivating and non-deactivating valves are presented. In one example, a position of an engine air intake throttle is adjusted during cylinder deactivation to control intake manifold pressure for cylinder reactivation. Closing of the throttle may be timed based on an actual total number of cylinder induction events expected to provide a desired engine intake manifold pressure.
