Abstract
Method, system and controller for electronically controlling a park-interlock device in a land-based vehicle are provided. The method allows for providing a driver-selectable shifter for selecting a respective one of a plurality of propulsion modes of the vehicle. One of the propulsion modes is a park mode. The method further allows for sensing at least one vehicle parameter for determining whether or not the park interlock device is to be actuated to a respective interlock state corresponding to the driver-selected mode and/or an operational mode automatically determined by a controller for stopping and starting during a Hill-hold function in an electric, hybrid electric vehicle. Memory is provided for storing nominal values for each vehicle parameter. A comparing action allows to compare the sensed vehicle parameters relative to the nominal parameter values stored in memory. Based on the results of the comparison, the method allows for generating a control signal for commanding the interlock device to the respective interlock state.
