Problems solved by technology

However, if the vehicle adopts a pure series drive scheme, it is easy to cause insufficient power when the vehicle is running at high speed. In addition, the vehicle adopts a pure parallel drive scheme, which is less economical when the vehicle is running at a low speed.
Therefore, it is difficult to realize the matched use of the series drive scheme and the parallel drive scheme on the hybrid vehicle at the same time, and it is difficult to realize the fuel economy of the vehicle under various working conditions.

Abstract

The invention discloses a hybrid vehicle and a control method and system thereof. The control method includes after the hybrid vehicle is powered on, detecting the SOC value of a power battery of the hybrid vehicle, the speed of the hybrid vehicle and the load of the hybrid vehicle; starting the corresponded operating mode of the hybrid vehicle according to the SOC value of the power battery, the speed and the load. The operating mode includes an EV1 mode, an EV2 mode, a serial connecting mode, a parallel-connection charging mode, a single engine mode, a motor assisting mode, an all drive mode and a brake feedback mode. According to the hybrid vehicle and the control method and system thereof, the power performance of the vehicle during high-speed driving can be guaranteed, the fuel economy of the vehicle during low-speed driving can be guaranteed, and energy can be saved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid vehicle, a control method and a control system for the hybrid vehicle. Background technique [0002] With the shortage of social energy, more and more people pay attention to new energy vehicles, among which hybrid vehicles have been developed rapidly. In the prior art, hybrid vehicles mainly include a pure series drive scheme and a pure parallel drive scheme. Among them, the pure series driving scheme mainly controls the switching of the working mode according to the SOC value of the vehicle, and the pure parallel driving scheme mainly controls the switching of the working mode by judging the vehicle speed. However, if the vehicle adopts a pure series drive scheme, it is easy to cause insufficient power when the vehicle is running at high speed. In addition, the vehicle adopts a pure parallel drive scheme, which is less economical when the vehicle is running at a low ...
