Embodiment

[0046] Example: figure 1 A flow chart of vehicle control of a pure electric vehicle in an automatic driving mode according to an embodiment of the present invention is shown. refer to figure 1 , The existing pure electric vehicles are equipped with 360-degree surround-view cameras, millimeter-wave radars, laser radars, ultrasonic sensors, GPS locators and navigation equipment. In the automatic driving mode, the automatic driving controller receives the signals sent by the above-mentioned on-board equipment in real time, and obtains real-time road conditions and vehicle surrounding environment information according to the received signals, and then determines driving requirements, including acceleration requirements, uniform speed requirements, deceleration requirements and steering need. After determining the driving demand, the automatic driving controller sends the driving demand to the vehicle controller. The vehicle controller sends relevant commands to the outside acco...

Abstract

The invention discloses a braking control method for a pure electric vehicle in an automatic driving mode. instruction and the vehicle braking influence parameter, and determine the braking control mode of the pure electric vehicle according to the predetermined braking control mode selection method; Control the car. According to the braking control method of the present invention, frequent charging and discharging of the power battery can be effectively limited, and the service life of the power battery can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and more specifically relates to a braking control method for a pure electric vehicle in an automatic driving mode. Background technique [0002] In recent years, with the increasingly prominent energy crisis and environmental problems, pure electric vehicles have shown a tendency to gradually replace traditional internal combustion engine vehicles. However, limited by the capacity of the power battery, the cruising range of existing pure electric vehicles is generally short. In this context, electric vehicle energy-saving technology has become a research focus and hotspot in the field of electric vehicles. Among them, electric vehicle braking energy recovery technology, as the main means of energy saving of electric vehicles, has received extensive attention from scholars at home and abroad. [0003] At present, with the maturation of electric vehicle braking energy recovery technol...
