Abstract

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. Thecontrol method comprises the steps that the gear of the multi-speed automatic transmission is determined based on a pedal signal for control; in the pure electric mode, an actual accelerator pedal signal is adopted as the pedal signal for control; in the internal combustion engine driving mode, an actual accelerator pedal signal is adopted as the pedal signal for control; and in the hybrid powermode, a virtual accelerator pedal signal is used as an input accelerator pedal signal. According to the invention, a mode transition process is performed when switching between the pure electric modeand the hybrid power mode or switching between the hybrid power mode and the internal combustion engine driving mode; in the mode transition process, the pedal signal for control is converted from theactual accelerator pedal signal to the virtual accelerator pedal signal or from the virtual accelerator pedal signal to the actual accelerator pedal signal.

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...
