The invention relates to a control method for a hybrid vehicle and the hybrid vehicle. The hybrid vehicle includes an internal combustion engine, a motor and a multi-speed automatic transmission. In the control method, the gear position of the multi-speed automatic transmission is determined according to the pedal signal used for control; in the pure electric mode, the actual accelerator pedal signal is used as the Pedal signal for control; in the internal combustion engine drive mode, the actual accelerator pedal signal is used as the pedal signal for control; in the hybrid mode, the virtual accelerator pedal signal is used as the input accelerator pedal signal. According to the present invention, when switching between pure electric mode and hybrid mode or between hybrid mode and internal combustion engine drive mode, a mode transition process is performed, in which the pedal signal for control is changed from the actual The accelerator pedal signal is converted to a virtual accelerator pedal signal or vice versa.
Description
technical field [0001] The invention relates to a control method for a hybrid vehicle and the hybrid vehicle. Background technique [0002] For a hybrid vehicle, especially a hybrid vehicle with a multi-speed automatic transmission, the efficiency and emission performance of the vehicle can be improved by switching the working mode (i.e. pure electric mode, internal combustion engine drive mode, hybrid mode) and transmission gear. . During the driving process of the vehicle, it is possible to switch between various working modes frequently, and the decision-making gear of the transmission during the switching period has an important impact on the economy, power and ride comfort of the vehicle. Usually, the gear position of the automatic transmission is determined using a shift table, in particular a look-up table, on the basis of a pedal signal for the control. Therefore, the pedal signal for control is crucial to obtain the proper gear. At the same time, for hybrid vehic...
