Problems solved by technology

[0005] On the other hand, when the ECO mode is selected, the required torque is reduced compared to the normal mode, and the slew rate is limited
However, the function of the ECO mode is to limit the switching speed, so it causes unnecessary torque even if the distance to the vehicle in front is small, which is not good for the fuel efficiency of the vehicle

Abstract

The invention relates to a system for controlling the acceleration torque of a vehicle. The system includes: a driving information detection unit that detects driving information of the vehicle; a forward-vehicle detector that detects the information about another vehicle located substantially ahead of the vehicle; and a control unit that calculates a basic acceleration torque and a basic slew rate of the vehicle when the vehicle is accelerating based on the detected driving information, calculates a desired acceleration torque and a final slew rate by correcting the basic acceleration torque and the basic slew rate based on the detected information about the other vehicle, and outputs a torque-related order to adjust a torque output from a power system of the vehicle to the desired acceleration torque in accordance with the final slew rate.

Description

technical field [0001] The present invention generally relates to systems and methods for controlling acceleration torque of a vehicle. More particularly, it relates to a system and method for controlling acceleration torque that can improve fuel efficiency by controlling acceleration torque based on information of nearby vehicles. Background technique [0002] Generally, when a driver operates an accelerator pedal of a vehicle rapidly, it has an adverse effect on the fuel efficiency of the vehicle. To prevent such problems, some vehicles utilize a driving mode called "ECO mode". [0003] In general, the ECO mode achieves the effect of improving fuel efficiency by limiting the acceleration torque change rate when the accelerator pedal is operated, compared with the normal mode. refer to figure 1 , in the normal mode, when the driver operates the accelerator pedal, the acceleration torque (ie, the basic acceleration torque of the power system) is determined as the required...
