Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0051] Such as figure 1 As shown, the driving control strategy adjustment method based on driving behavior in this embodiment includes the following steps: S1. Obtain the acceleration value of the vehicle; S2. Determine the driving type according to the acceleration value with a preset judgment standard; S3. Determine the driving mode by setting the change in the time period; S4. Adjust the vehicle driving control strategy according to the driving mode.

[0052] In this embodiment, the judging criteria in step S2 include: according to the driving type, the acceleration value is divided into non-overlapping acceleration intervals corresponding to the driving type, and the duration threshold value corresponding to the acceleration interval is set. When the acceler...

Abstract

The invention discloses a driving control strategy adjustment method and system based on driving behaviors. The method comprises the following steps: S1, obtaining a vehicle acceleration value; S2, determining a driving type by a preset judgment standard according to that acceleration value; S3, Determining a driving mode according to the changes of the driving type in a preset period of time; S4,Adjusting the vehicle driving control strategy according to the driving mode. The method and system can automatically adjust the control strategy of the vehicle according to the driving habit of thedriver, so that the vehicle has the advantages of high safety and comfort under the operation of different drivers.

Description

technical field [0001] The present invention relates to the field of vehicle driving control, in particular to a driving behavior-based driving control strategy adjustment method and system, especially for real-time adjustment of the vehicle's accelerator pedal analysis and vehicle power for new energy vehicles according to the driver's driving behavior output. Background technique [0002] In the prior art, the analytical parameters of the accelerator pedal of the new energy vehicle are fixed and will not be changed for adaptation due to the driver's driving habits. However, due to the differences in the driving behaviors of different drivers, violent driving will lead to poor ride comfort, and passengers in the car will not be able to stand firmly and cause falls. At the same time, energy consumption will also be greatly increased, which seriously reduces the safety and Comfort, there is an urgent need for a vehicle driving control technology that can have high safety and...
