A novel intelligent assisted driving device and method of using the same

Abstract

The invention discloses a novel intelligent aided driving device. The novel intelligent aided driving device comprises an engine electronic controller, a pedal openness sensor and an accelerator position sensor, wherein the engine electronic controller is connected with an intelligent fuel economizing controller; a data acquisition unit is built in the intelligent fuel economizing controller; theengine electronic controller acquires a signal of the pedal openness sensor and a signal of the accelerator position sensor; then the engine electronic controller sends the signals to the data acquisition unit through a CAN bus; and the intelligent fuel economizing controller carries out overall arrangement and calculation according to the acquired data and then sends an engine rotational speed limit instruction to an ECU, and an engine rotational speed is controlled through controlling the openness of a pedal. According to a method using the novel intelligent aided driving device, during running of an automobile, the intelligent fuel economizing controller is capable of controlling the engine rotational speed to be a set rotational speed less than the real-time rated rotational speed of an engine. The novel intelligent aided driving device disclosed by the invention has the advantages of realizing the maximum of fuel efficiency while ensuring the maximum power of the engine, and realizing intelligent fuel economizing on the premise of ensuring an invariable driving habit.

Description

technical field [0001] The invention relates to a novel intelligent auxiliary driving device and a method for using the device. Background technique [0002] Existing vehicles are equipped with engine electronic control systems, and the built-in control strategy can ensure that the engine speed output is adjusted according to the set control strategy. When the engine is developed, the fuel consumption rate is low. When the engine runs in this area, it is more fuel-efficient. Therefore, the vehicle The green area is generally marked on the tachometer. When the engine is working normally, it corresponds to its rated speed, and the rated speed refers to the speed corresponding to the maximum power point of the engine. [0003] In the prior art, there are many intelligent assisted driving systems, all of which adopt appropriate electronic control technology to make the engine speed of the car close to the speed-torque relationship curve of the vehicle, so as to achieve the best...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned intelligent assisted driving system only controls the pedal, accelerator and other devices, and maintains the engine speed at the rated speed through accelerator control, so as to achieve the purpose of saving fuel, and the engine speed runs in the economical fuel consumption area as much as possible to achieve the purpose of saving fuel. Therefore, the existing The intelligent driving system in the technology has the shortcomings of not obvious fuel saving effect and prone to control failure
