Method and system for controlling driving mode of a hybrid electric vehicle

Abstract

The invention provides a hybrid electric vehicle driving mode control method and system. The method comprises the steps that clock information, the accelerator depth corresponding to the clock information and the vehicle speed corresponding to the clock information are acquired; the accelerator depth variation quantity and the accelerator variation rate in the first preset time period are calculated according to the clock information and the accelerator depth corresponding to the clock information; the demanded driving mode of a vehicle is judged according to the accelerator depth variation quantity, the accelerator variation rate, the clock information and the accelerator depth corresponding to the clock information in the first preset time period; the vehicle driving mode is adjusted according to the vehicle demanded driving mode obtained through judgment; and the engine wheel end torque and the motor wheel end torque are adjusted according to the vehicle driving mode and the vehiclespeed corresponding to the current clock information. According to the hybrid electric vehicle driving mode control method and system, the vehicle driving mode is judged by detecting the acceleratordepth, the accelerator variation quantity and the accelerator variation rate in the set time, an engine and a motor are adjusted according to the driving mode, automatic adjusting of the vehicle is achieved, and a driver is helped to get familiar with the vehicle.

Description

Technical field [0001] The present invention relates to the field of vehicle control technology, and more particularly to a hybrid vehicle drive mode control method and system. Background technique [0002] The current vehicle is driving because the vehicle itself is different. For the driver to repeatedly adapt, for example, in the depth of the same throttle, some cars have even suddenly appear, and some cars are relatively weak. In order to give a certain degree of deep step or feel inadequate; generally, the vehicle cannot achieve its own regulation, helping the driver faster familiar with the vehicle, the driving experience is not good during driving, or there is another extreme, waste energy. Inventive content [0003] In order to solve the above technical problems, the present invention provides a hybrid vehicle driving method control method and system, and the resolved vehicle itself is unable to adjust to accommodate the driver's problem. [0004] A hybrid vehicle drivin...
