Self-adaptive control system of whole vehicle

Abstract

The invention provides a whole vehicle self-adaptive control system which is characterized in that a vehicle working condition identification module is electrically connected with a vehicle speed sensor; the mountainous area ramp identification module is electrically connected with the vehicle speed sensor, the atmospheric pressure sensor, the accelerator pedal and the engine; the vehicle working condition identification module and the mountainous area ramp identification module are electrically connected with the fuel injection control module; the vehicle working condition identification module and the mountainous area ramp identification module are electrically connected with the torque path control module; the vehicle working condition identification module and the mountainous area ramp identification module are electrically connected with the air system control module; and the vehicle working condition identification module and the mountainous area ramp identification module are electrically connected with the post-processing system control module. The control strategy is adaptively adjusted according to the current working condition of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of engine electronic control, and in particular relates to a vehicle adaptive control system. Background technique [0002] The existing control method for vehicle adaptive working conditions is to use two kinds of driving characteristic MAP curves, which are switched by a fuel-saving switch. When the fuel-saving switch in the cab is pressed, the driving characteristic curve of the whole vehicle follows the MAP curve of fuel-saving driving characteristics. At this time, the driver steps on the accelerator, the rate of change of the accelerator will slow down, and the speed of engine torque increase will slow down, so as to realize slow refueling and achieve economization. The purpose of oil; when the fuel-saving switch in the cab is released, the vehicle will follow the MAP curve of dynamic driving characteristics. At this time, the driver steps on the accelerator, the rate of change of the accelerator will ...

AI Technical Summary

Problems solved by technology

[0003] The existing vehicle adaptive working condition control method requires manual switching, which cannot be automatically switched according to changes in road conditions; at the same time, it is impossible to select different engine fuel injection timing, injection pressure, Combustion parameters such as EGR rate cannot achieve the optimal solution for fuel consumption
