Embodiment Construction

[0038] figure 1 is a flowchart of a method for controlling torque output of a hybrid vehicle according to an embodiment of the present invention. like figure 1As shown, the method for controlling the torque output of a hybrid vehicle disclosed in the present invention includes the following steps: (A1) When the driver demand torque suddenly increases, the actual torque output of the vehicle is controlled in the following manner: in the initial stage, by The filtering method controls the rate of rise of the vehicle output torque, so that the rate of increase of the vehicle output torque gradually increases with time (this can ensure that the vehicle control system responds quickly to the driver's demand torque), until it reaches the maximum rate of increase allowed by the vehicle system; Subsequently, in the middle stage, the vehicle output torque is increased at the maximum rate allowed by the vehicle system; finally, in the end stage, the rate of increase of the vehicle outp...

Abstract

The invention discloses a method for controlling the torque output of a hybrid vehicle. The method is capable of controlling the ascending rate or the descending rate of the output torque of the vehicle by means of filtering when a driver requires the sudden increase or reduction of the torque. The method for controlling the torque output of the hybrid vehicle disclosed by the invention is capable of ensuring the torque response characteristics of a vehicle control system, and improving driving comfort.

Description

technical field [0001] The present invention relates to methods for controlling the torque output of a vehicle, and more particularly, to methods for controlling the torque output of a hybrid vehicle. Background technique [0002] Currently, with the increasing development and popularization of electric / hybrid vehicles, the driving comfort of vehicles is becoming more and more important. Among them, in hybrid vehicles, compared with the engine, the motor has excellent torque response characteristics, that is, it can realize fast and accurate tracking and response to the driver's demand torque (ie, the required vehicle output torque). [0003] However, the existing technical solutions have the following problems: when the driver's demand torque changes rapidly (in actual road driving, the driver's demand torque may suddenly increase or decrease, etc.), if the power system directly responds to this torque If the demand is high, it will cause the entire vehicle to vibrate seve...
