A kind of intelligent throttle control method

Abstract

The invention discloses an intelligent accelerator control method. The intelligent accelerator control method comprises the following steps: vehicle position information is obtained and sent to a common rail row; the common rail row sends the vehicle position information and road spectrum information to an ECU; the ECU determines a gradient of the position of a vehicle according to the obtained vehicle position information and road spectrum information, determines a corresponding rotating speed-torque MAP graph according to the gradient, and determines MAP correcting coefficients according tothe weight of the vehicle and the length of the slope; the ECU judges if the MAP graph needs to be switched according to a vehicle accelerator change rate; when the switching is needed, the MAP graphis switched, and the torque is corrected; and a vehicle accelerator is controlled according to the corrected torque. The engine output torque can be adjusted according to the weight of the vehicle andthe road spectrum information to solve the problems of insufficient power in the vehicle upslope and high oil consumption caused by bad driving habits.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an intelligent accelerator control method. Background technique [0002] With the improvement of living standards and the strengthening of environmental protection awareness, electronically controlled vehicles have become more and more popular among the public. In order to adapt to the different driving habits of different drivers, existing vehicles will be equipped with several different pedals inside the electronic control unit ECU. Torque characteristic, the voltage signal related to the accelerator pedal opening degree is connected to the ECU, and the ECU obtains the engine target torque according to the accelerator pedal opening degree and the pedal torque characteristic, so as to realize the control of the engine torque. The above-mentioned different pedal torque characteristics represent sports, economy and general modes, etc. The driver will choose one of the driving mod...

AI Technical Summary

Problems solved by technology

The above-mentioned different pedal torque characteristics represent sporty, economical and general modes, etc. The driver will choose one of the driving modes according to his driving habits. At this time, the pedal torque characteristics are fixed. The pedal opening is used to obtain torque, which cannot be adjusted according to vehicle weight and road map information. Therefore, when the driver has bad driving habits, the problem of high fuel consumption will occur, and when the vehicle goes uphill, the driver will feel that the vehicle is underpowered, which affects Driver's Driving Experience
