Electric automobile and control method thereof

Abstract

The invention relates to an electric automobile and a control method thereof. The control method of the electric automobile comprises the step of detecting the current position of a pedal, the step of calculating the position change state and movement speed of the pedal according to detection signals, the step of connecting a motor to an output loop of a first battery when the pedal position is changed into the speed regulating area from the braking area and a switch of the whole automobile is in a turn-on state, the step of cutting off the connection between the motor and the output loop of the first battery and connecting the motor to a storage loop of a second battery and starting a brake device when the pedal position is changed into the braking area from the speed regulating area, the step of cutting off the connection between the motor and the output loop of the first battery and connecting the motor to the storage loop of the second battery and starting the brake device when the movement speed of the pedal is larger than the preset value, and the step of adjusting the revolving direction and the revolving speed of the motor according to the gear information and the pedal position value when the pedal changes in the speed regulating area and the switch of the whole automobile is in a turn-on state.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and in particular to an electric vehicle and a control method thereof. Background technique [0002] The rising number of cars has raised a series of problems. Most cars burn fossil fuels such as gasoline, diesel, and natural gas. The reserves of fossil fuels on the earth are limited, and the huge and increasing number of cars makes the energy crisis increasingly serious. The weight of a traditional car is generally about 1500kg, and the payload is only about 100kg. Most of the energy is wasted on the invalid load, resulting in serious energy waste. In addition, traditional cars are bulky, and the average car covers an area of ​​about 10 square meters. The increase in the number of cars has made the problems of traffic congestion and parking spaces more and more serious. [0003] In recent years, electric vehicles have been welcomed by more and more consumers. The price of electric v...
