Power control method and device for intelligent car

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.
