LEARNING METHOD FOR A CONTROLLED TRANSMISSION GRID FOR A HYBRID VEHICLE, AND TRANSMISSION ESPECIALLY FOR HYBRID VEHICLE

摘要

According to the invention, in order to overcome the inertia which is generated by the electric motor at the inlet of the transmission and may falsify the learning process, the electric motor (12) is controlled in such a way as to generate, on the primary shaft, a determined moment which is sufficient to generate a first rotation of the primary shaft in a first direction, followed by a second rotation of the primary shaft in a second opposite direction, in order to overcome the artificial abutment which is known as the dog clutch wall and identified as creating an effort which is higher than an acceptable determined effort due to the non-alignment of the dogs, thereby causing the realignment of the dogs of the ring gear and the dog clutch sleeve, and enabling the correct learning of the abutments.
