Abstract

The invention provides a control method and system of an electric automobile and the electric automobile. The control method comprises the steps that a first state identification of a first state which an integrated controller is in at present is acquired; when the first state belongs to first-class states, first preset operation corresponding to the first state identification is carried out according to the first state identification, and the first state identification is sent to a plurality of high and low pressure parts; the current state which the high and low pressure parts are in at present and is fed back by the high and low pressure parts after the high and low pressure parts carry out second preset operation corresponding to the first state identification according to the first state identification is received; when the result of the first preset operation and the state which the high and low pressure parts are in at present meet the skip condition of a preset state machine, the integrated controller is switched into a second state from the first state, and the state identification of the current state which the integrated controller is in is updated to a second state identification of the second state. The control method simplifies the process of powering on and off, and meanwhile the purpose of easily positioning abnormal points in the process of powering on and off can be achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, a control system and an electric vehicle for an electric vehicle. Background technique [0002] In the face of increasingly severe energy and environmental problems, energy-saving and new energy vehicles are becoming the focus of current research in various countries. In my country, energy-saving and new energy vehicles have been highly valued by the government and industry, and have been designated as one of the strategic emerging industries. As a type of energy-saving and new energy vehicles, pure electric vehicles have many advantages such as no exhaust emissions, high energy efficiency, low noise, and recyclable energy during driving. Therefore, vigorously developing pure electric vehicles is beneficial to energy security and environmental protection has great significance. [0003] With the rapid development of pure electric vehicles, integrated contr...
