Abstract

The invention relates to a control method, device and system of a hybrid vehicle, and the vehicle. The control method comprises the steps of determining corresponding engine output power in an external characteristic curve according to target vehicle speed, enabling the engine output power to be greater than whole vehicle required power, enabling the whole vehicle required power to be driving power required when the vehicle runs at the target vehicle speed, and controlling load power of a power motor to be equal to the power difference between the engine output power and the whole vehicle required power by adjusting a duty cycle and pulse width of the power motor. The control method of the hybrid vehicle provided by the invention can reduce the fuel loss and improve the energy utilization.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a control method, device, system and automobile of a hybrid electric automobile. Background technique [0002] In recent years, with the increasing energy and environmental requirements, how to improve the fuel efficiency of traditional internal combustion engine vehicles, how to achieve high energy efficiency utilization and low-emission vehicle design matching technology has attracted more and more attention. [0003] In the process of traditional car driving matching, although the engine itself can achieve high fuel efficiency and has the most economical fuel curve, the speed and torque of this fuel economy curve are in one-to-one correspondence, and the actual vehicle operating conditions often Different torque outputs are required at the same vehicle speed. In order to meet the needs of the vehicle, it is often necessary to design a certain power margin during the...
