A powered latch system for a door of a vehicle including a latch assembly, actuatable inside and outside handles, a powered actuator and a door controller that causes the powered actuator to unlatch the latch assembly upon actuation of the inside and outside door handles. The latch assembly may be mechanically unlatched by a user within a vehicle interior even if the powered actuator does not actuate due to a loss of electrical power or other failure. The controller can be programmed to unlatch the latch assembly according to various criteria as required to meet the specific requirements of different markets.

1. A method of configuring vehicle side door latch assemblies, the method comprising: providing front and rear latch assemblies having substantially identical construction, wherein each latch assembly is configured to retain vehicle front and rear side doors in fully closed positions when latched, and permits a vehicle side door to open when unlatched, and wherein each latch assembly includes a powered actuator that selectively unlatches the latch assembly;providing a control system;providing a front inside door handle;providing a rear inside door handle;providing a first mechanical linkage that provides for mechanical unlatching of the front latch assembly by a user within a vehicle interior when the front door of the vehicle is fully closed without actuation of the powered actuator of the front latch assembly;providing a second mechanical linkage that provides for unlatching of the rear latch assembly by a user within a vehicle interior when the rear door of the vehicle is fully closed without actuation of the powered actuator of the rear latch assembly;operably connecting the front and rear inside door handles to the control system;operably connecting the powered actuators of the front and rear latch assemblies to the control system; and wherein:the control system includes a lock state for the front and rear latch assemblies, the lock states comprising at least one of an unlocked state and a double locked state, wherein the control system further includes a child lock state for the rear latch assembly; and wherein, if the vehicle has sufficient electrical power, the control system unlatches the front latch assembly if the front inside handle is actuated unless the front latch assembly is in a double locked state; and wherein, if the vehicle has sufficient electrical power, the control system unlatches the rear latch assembly if the rear inside handle is actuated and the lock state of the rear latch assembly is unlocked, the child lock state is off, and the rear latch assembly is not in a double locked state. 2. The method of configuring vehicle side door latches of claim 1, including: providing front and rear outside door handles;operably connecting the front and rear outside door handles to the control system; and wherein:the control system unlatches the front latch assembly if a user actuates the front outside handle and the vehicle has electrical power if the control system receives an authorization signal meeting predefined security criteria and if the front latch assembly is not in a double locked state, and wherein the control system unlatches the rear latch assembly if a user actuates the rear outside handle and the vehicle has electrical power if the control system receives an authorization signal meeting predefined security criteria and if the rear latch assembly is not in a double locked state. 3. The method of configuring vehicle side door latches of claim 1, including: operably interconnecting the front latch assembly to the front inside door handle utilizing the first mechanical linkage. 4. The method of configuring vehicle side door latches of claim 3, wherein: the front inside door handle mechanically unlatches the front latch assembly if the front inside door handle is actuated twice. 5. The method of configuring vehicle side door latches of claim 4, including: operably interconnecting the rear latch assembly to the rear inside door handle utilizing the second mechanical linkage. 6. The method of configuring vehicle side door latches of claim 5, wherein: the rear inside door handle mechanically unlatches the rear latch assembly if the rear inside door handle is actuated twice. 7. The method of configuring vehicle side door latches of claim 1, including: operably interconnecting the front latch assembly to the front inside door handle utilizing the first mechanical linkage;providing a front emergency inside toggle that can be manually actuated by a user within a vehicle interior; andoperably interconnecting the front emergency inside toggle to the first mechanical linkage whereby actuation of the front emergency inside toggle followed by actuation of the front inside door handle mechanically unlatches the front latch assembly even if the powered actuator of the front latch assembly is not actuated. 8. The method of configuring vehicle side door latches of claim 7, including: operably interconnecting the rear latch assembly to the rear inside door handle utilizing the second mechanical linkage;providing a rear emergency inside toggle that can be manually actuated by a user within a vehicle interior; andoperably interconnecting the rear emergency inside toggle to the second mechanical linkage whereby actuation of the rear emergency inside toggle followed by actuation of the rear inside door handle unlatches the rear latch assembly even if the powered actuator of the rear latch assembly is not actuated. 9. The method of configuring vehicle side door latches of claim 1, including: providing an emergency front inside lever that can be actuated by a user within a vehicle interior; andoperably interconnecting the emergency front inside lever to the front latch assembly utilizing the first mechanical linkage such that actuation of the emergency front inside lever mechanically unlatches the front latch assembly even if the powered actuator of the front latch assembly is not actuated. 10. The method of configuring vehicle side door latches of claim 9, including: providing an emergency rear inside lever that can be actuated by a user within a vehicle interior; andoperably interconnecting the emergency rear inside lever to the rear latch assembly utilizing the second mechanical linkage such that actuation of the emergency rear inside lever mechanically unlatches the rear latch assembly even if the powered actuator of the rear latch assembly is not actuated.
