Abstract

The invention provides an automatic gear shifting method based on driving habits of a driver and a vehicle controller. In a vehicle with a manual-automatic integrated transmission, when the vehicle state is a manual gear shifting mode, current gear shifting related information of the vehicle is acquired in real time and includes gradient information, gear shifting information, an accelerator pedal opening degree and vehicle speed; when a gear change of the vehicle is found and the gear shifting operation meets preset conventional gear shifting operation, the current gear shifting related information of the vehicle is recorded; and according to the recorded current gear shifting related information of the vehicle, a preset automatic gear shifting strategy is modified. According to the automatic gear shifting method based on the driving habits of the driver and the vehicle controller, the driving habits of the driver are obtained in the manual gear shifting mode, the gear shifting strategy in the automatic gear shifting mode is modified according to the driving habits, and therefore driving in the automatic gear shifting mode also meets the driving habits of the driver , the user experience feeling is improved, and the intelligent performance of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile gear shifting, and in particular relates to an automatic gear shifting method and a vehicle controller based on the driver's driving habits. Background technique [0002] With the continuous development of science and technology, car owners' requirements for car performance are constantly increasing, and at the same time, the fields of intelligent functions of cars are constantly increasing. At present, many vehicles are automatic / manual integrated transmissions. When vehicles with automatic transmissions formulate gear shift strategies, most of them consider vehicle economy or vehicle dynamics, so as to find the appropriate shifting speed. When the vehicle speed reaches the shifting speed, the vehicle automatically shifts gears, so as to achieve the purpose of automatic shifting. However, drivers have different driving habits. Some drivers expect to reach high-speed gears as soon as possible,...
