METHOD FOR CONTROLLING A HYBRID DRIVE SYSTEM, FOR A HYBRID VEHICLE

摘要

The invention relates to a method for controlling a hybrid drive system, for a hybrid vehicle comprising a first power train having at least one heat engine (MTH) for a first running gear and a second electrically driven running gear system (14). The invention also relates to a strategy to control coupling and uncoupling for an jaw clutching system (30) inserted between a hybridisation machine (MELAR) and drive wheels of the second running gear with hybridisation, which involves a raw request step to open dogs of the jaw clutching system (30) followed either by a step of validating the opening of the dogs or a step of preventing the opening of the dogs, according to whether the first power train is coupled or uncoupled, respectively, such that said power train and the second running gear system cannot be simultaneously free-wheeling when the vehicle is in motion.
