Abstract

The invention relates to a pure electric manual shift gear car power assembly and a control strategy thereof. The pure electric manual shift gear car power assembly is characterized in that a power assembly part comprises a special driving motor of an electric vehicle and a controller; a gearbox adopts a 5-gear manual gearbox; and a DCDC and a charger adopt mature products to match a correspondingair compressor, a high voltage distribution box, a vacuum booster system and an electric steering system so as to guarantee that a power assembly system can be implemented. The control strategy has six modes, which are respectively an initial mode, a static mode, a no-load idling mode, a power mode and a stalling mode. The strategy research on different modes of the vehicle from a static state tostarting, to the normal running of the vehicle, to the follow-up normal gear shifting and so on, consistencies between the modes, such as the static mode, starting mode, the gear shifting mode and soon, of the vehicle and those of the traditional gasoline engine vehicle are guaranteed.

Description

technical field [0001] The invention relates to a power assembly of a pure electric manual transmission car and a control strategy thereof, and belongs to the technical field of driving power of vehicle engineering. Background technique [0002] With the aggravation of world energy shortage and environmental pollution, energy conservation and environmental protection have become the development direction of modern automobiles. The driving training industry is an important part of the transportation industry. It is both a resource-occupied and energy-consuming industry, and it has a great impact on the environment. Moreover, as the future development direction of the industry, the indoor driving training framework has a relatively broad market prospect for manual transmission electric vehicles. At present, there is almost no electric car that can be used as a manual transmission school bus in the domestic market. There is no corresponding design for the control strategy of i...
