Hybrid-vehicle drive controlling method, involves determining optimized operational position of gear and controlling operational position of gear based on determined optimized operation position using gear control device

摘要

The method involves detecting a charging power of a high performance battery (8) for an electric motor (5). Fuel consumption parameters are determined for different operational positions of a gear (2). An optimized operational position is determined for indicating the determined fuel consumption parameter of an optimized fuel consumption. The operational position of the gear is controlled based on the determined optimized operation position using a gear control device. An independent claim is also included for a device for controlling a hybrid-vehicle drive.
