Abstract

The invention relates to a vehicle intelligent control system and a control method. The vehicle intelligent control system can judge the power requirement and the load size of a vehicle according to a driving state of the vehicle, and switch the running modes of the vehicle automatically based on the determined power requirement and the load size. The vehicle intelligent control system comprises an accelerated pedal MAP memory module, a vehicle running information collecting calculation module and a driving mode switching execution module; the accelerated pedal MAP memory module is arranged in an engine electric control unit, and an economic mode pedal MAP, a power mode pedal MAP and a fuel-saving mode pedal MAP are stored in the accelerated pedal MAP memory module; the vehicle running information collecting calculation module collects vehicle running information in the running process of the vehicle and conducts comprehensive and overall calculation so as to determine the operation condition of the vehicle; the driving mode switching execution module judges whether the current driving mode of the vehicle is matched with the determined operation condition or not, if yes, the current driving mode is maintained; and if no, the accelerated pedal MAP memory module is synergized to execute switching of the driving modes so as to adapt to the current operation condition.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a vehicle intelligent control system and a control method thereof. Background technique [0002] In the accelerator pedal control strategy of existing vehicles, the accelerator pedal MAP is usually fixed, that is, only one kind of accelerator pedal MAP is stored in the electronic control unit (ECU) of the engine, and the opening degree of the driver's stepping on the accelerator pedal is calibrated by querying A good accelerator pedal MAP can obtain the torque demand of the vehicle, and then convert it into fuel injection quantity to realize fuel injection. Although there are also engines equipped with electronic control units that store multiple accelerator pedal MAPs, the driver can only adjust the accelerator pedal MAP autonomously according to driving habits or road conditions to achieve different power requirements of the vehicle. Contents of the invention [0003] The ob...
