Embodiment 1

[0041] The brake pedal value corresponding to the corresponding deceleration in different speed ranges is obtained by the method described, and when the vehicle needs to be braked during driving, an appropriate deceleration is selected according to the driving speed, and then the brake pedal value is obtained by the method, controlled by the controller The controller controls the movement of the brake pedal to realize brake control.

Abstract

The invention relates to the technical field of automotive control, in particular to a method for controlling deceleration and braking through curve fitting. The method comprises the following steps of collecting driving speed, brake pedal values and deceleration during braking in a driving process, and dividing a plurality of speed intervals according to the driving speed in order to obtain the brake pedal values corresponding to the corresponding deceleration in different speed intervals; and subsequently obtaining a corresponding brake value according to the required deceleration in order to realize the brake control of a driving tool. Compared with the prior art, the method has the advantages that the proper brake value can be obtained through a large amount of data fitting under a condition that a vehicle model is not known, and through the curve fitting of the deceleration speed and the brake values in different intervals, the corresponding brake value can be obtained according to the required deceleration, so that the brake control of the driving tool is realized; and the method is suitable for the common driving tools to assist a driver for braking control, and the safety problem caused by improper treading of a brake pedal is reduced from the source.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a method for controlling deceleration and braking through curve fitting. Background technique [0002] During the driving process of the vehicle, reasonable control of the brakes has an important impact on driving safety. Due to the influence of driving skills or other factors, it is easy to step on the brake pedal too heavily during the process of driving and starting and stopping the vehicle, resulting in a short-term delay in the speed of the vehicle. The phenomenon of sudden changes, or the situation that the brake pedal is too light to achieve effective braking. In this regard, my country's patent publication number CN106218641A discloses a vehicle novice driver automatic identification system, the system recognizes novice drivers by obtaining vehicle brake pedal signals, etc., and sets a more reasonable safe distance between vehicles and early warning time to imp...
