Automatic cruise control method for electric vehicle

Abstract

The invention provides an automatic cruise control method for an electric vehicle. The method comprises the following steps: collecting a pedal position by a vehicle controller; collecting a vehicle speed by the vehicle controller; collecting whether an obstacle exists in a safe distance threshold value in the front of the electric vehicle by the vehicle controller; performing the following judgment by the vehicle controller: judging that a driving intention of a driver is automatic cruise when the conditions that the vehicle speed is higher than or equal to a cruise speed threshold value, the pedal is positioned at the highest position and the obstacle does not exist in the safe distance threshold value in front of the electric vehicle are simultaneously met; and adjusting a pulse signal of a motor controller in real time by the vehicle controller, so that the real-time vehicle speed is always consistent with the cruise speed. The automatic cruise control method for the electric vehicle is applicable to a single-pedal four-wheel electric vehicle, any switch is not needed, the operation is simple and convenient, and the driving fatigue problem is solved. Moreover, the vehicle is provided with a protection function, and the driver can be effectively prevented from mistakenly operating in emergency to avoid danger.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an automatic cruise control method for electric vehicles. 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. Electric vehicles are welcomed by more and more consumers. The price of electric vehicles is lower than that o...
