Abstract

The invention discloses a power control method and device for an intelligent car. Power distribution modes of an engine are switched by detecting the battery charge state and demand torque parameters,thus the driving comfort of the intelligent car can be optimized, the power performance of the car is maintained, and the purposes of energy conservation and emission reduction are achieved; the working state of the engine is controlled according to the running power of the intelligent car, and thus the running time of the intelligent car can be prolonged under the premise of saving the power ofthe intelligent car; the climbing angle of the car is obtained, the minimum traction force numerical value required by climbing is calculated and generated according to the climbing angle of the intelligent car and the gravity of the intelligent car, then power output of a car engine controller is controlled through the traction force numerical value, and thus power output of the intelligent car can be flexibly controlled during uphill of the car; and the torque of the engine is adjusted according to acceleration parameters and the rotating number of a driving wheel of the intelligent car, thus the car can be prevented from excessive wasting power output under the sliding state, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of vehicle power control, in particular to a power control method and device for an intelligent vehicle. Background technique [0002] An intelligent vehicle is a comprehensive system that integrates functions such as environmental perception, planning and decision-making, and multi-level assisted driving. It uses technologies such as computers, modern sensing, information fusion, communication, artificial intelligence, and automatic control. technology complex. At present, the research on intelligent vehicles is mainly devoted to improving the safety and comfort of automobiles, and providing an excellent human-vehicle interaction interface. In recent years, intelligent vehicles have become a research hotspot in the field of vehicle engineering in the world and a new driving force for the growth of the automobile industry. Many developed countries have incorporated them into their respective intelligent tra...
