Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0042] In view of the lack of judging the state of the vehicle load in the current vehicle control, it often occurs that the output of the clutch does not match the power requirements of the vehicle. Since the accurate judgment of the vehicle load provides a calculation basis for the clutch pressure control compensation, it directly affects the output of the clutch, which is likely to cause energy waste. The present invention provides a control method and system for calculating the load of the whole vehicle. The load of the whole vehicle is determined by the ratio of the theoretical acceleration of the whole vehicle to the actual acceleration, so as to solve the problem of inaccurate control of the existing whole...

Abstract

The invention relates to a control method and a control system for integral vehicle load computation. The control method includes: acquiring an engine speed, a rotating speed of an output shaft of a gearbox and engine torque when a brake pedal is not in a braking state and a clutch is in a slipping friction state; determining a theoretical acceleration speed of an integral vehicle according to the engine speed and the engine torque; computing an actual acceleration speed of the integral vehicle according to the rotating speed of the output shaft of the gearbox; determining the load of the integral vehicle according to a ratio of the actual acceleration speed and the theoretical acceleration speed of the integral vehicle and an accompanying mass of the integral vehicle. The control method and the control system solve the problem of inaccuracy in integral vehicle control and are capable of reducing energy waste and improving power performance and economic performance of the integral vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile gearboxes, in particular to a control method and system for calculating the vehicle load. Background technique [0002] A typical wet dual clutch transmission consists of two coaxial nested or parallel clutches, two coaxial, inner and outer nested input shafts, two parallel output shafts, and multiple clutches arranged on the output shafts. It consists of a synchronizer device, multiple shift forks and a differential. The odd and even gear input gears of the transmission are respectively arranged on two input shafts, through the switching of two clutches and the action of different synchronizers, torque conversion and output are realized through different output shafts. The load of the vehicle has a direct impact on the torque conversion and output of the output shaft. The load of the vehicle is an important basis for the control and compensation of the clutch. The existing clutch control is m...
