Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Rapid acceleration will cause the ratio of fuel and air to be out of balance, resulting in insufficient combustion and reducing the efficiency of fuel combustion. According to relevant tests, the fuel consumption of the driver due to rapid acceleration during driving operation is more than 40% higher than that of the excellent slow acceleration operation. And then cause the fuel consumption of vehicle operation to rise more, the high then can reach more than 30%.

[0020] The macroscopic manifestation of rapid acceleration on the vehicle is the acceleration change of the vehicle. The present invention collects the vehicle’s driving acceleration, based on the vehicle’s gear position at the time, and through certain control logic, the vehicle can be driven according to a predetermined reasonable acceleration range, and the acceleration can be controlled. ...

Abstract

The invention relates to the field of automobile energy conservation, in particular to an acceleration control-based automobile energy conservation method and system thereof. The technical scheme of the present invention obtains the current acceleration and the current gear of the car through real-time calculation, and according to the relationship between the current acceleration and the target acceleration interval corresponding to the current gear, reasonably adjusts the accelerator pedal signal to control the current acceleration of the car to the target acceleration, and realizes the driving operation Active intervention, thereby reducing fuel consumption when the car is running.

Description

technical field [0001] The invention relates to the field of automobile energy conservation, in particular to an acceleration control-based automobile energy conservation method and system thereof. Background technique [0002] Relevant studies have shown that under certain conditions such as vehicles and road conditions, different driving operations of the driver can lead to a difference of 30% or even higher in the fuel consumption of the vehicle. Under certain conditions such as vehicles and road conditions, the driving operation of the car driver plays a decisive role in the fuel consumption of the car, and rapid acceleration is an important factor that leads to the increase of the fuel consumption of the car. [0003] According to the analysis of the rapid acceleration of the vehicle, besides the driver's operation factors, the rapid acceleration also has a certain relationship with the performance configuration of the vehicle itself. Some vehicles are equipped with a r...
