[0003] The braking system of the vehicle in the prior art includes brake braking, manual braking, etc. In the traditional situation, when the driver encounters an emergency, he usually releases his right foot stepping on the accelerator quickly, and moves to the brake pedal at the same time. , and depress the brake pedal. When the brake pedal is depressed, the vehicle speed will decrease. During this process, the vehicle speed will basically maintain the original vehicle speed. That is to say, the brake operation cannot be responded in time when the driver finds an emergency , there is a possibility of delaying the operation, which poses a great threat to the driving safety of the vehicle

Embodiment Construction
[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0042] The core of the present invention is to provide a pre-braking method and system based on recognition mode. The method and system can achieve accurate and timely pre-braking of the vehicle, which precedes the operation of the brake pedal, and can effectively avoid vehicle distress problems. , Provide safety guarantee for driving.
[0043] Please refer to Figure 1 to Figure 3 , figure 1 It is a flowchart of specific embodiment 1 of ...

The invention discloses a recognition mode based pre-braking method and system. The method comprises steps as follows: S1, opening of an accelerator pedal is detected, and when the opening of the accelerator pedal is reduced, lifting-up speed of the accelerator pedal is acquired; S2, whether the lifting-up speed is higher than or equal to 80% of fully-lifting-up speed of the accelerator pedal is judged, if the lifting-up speed is not higher than or equal to 80% of the fully-lifting-up speed of the accelerator pedal, the opening of the accelerator pedal is detected again, if the lifting-up speed is higher than or equal to 80% of the fully-lifting-up speed of the accelerator pedal, the lifting-up speed is compared with the minimum speed in a white list storage, whether the lifting-up speed is higher than the minimum speed is judged, if the lifting-up speed is not higher than the minimum speed, S3 is executed, if the lifting-up speed is higher than the minimum speed, a pre-braking signal is sent to a braking device of a vehicle, and S3 is executed after the braking signal is sent; S3, the state of a braking pedal is monitored continuously, and if opening of the braking pedal in preset time is not zero or the opening is increased, the corresponding lifting-up speed is stored to the white list storage. According to the method and the system, braking can be implemented before a driver steps on the braking pedal, so that erroneous judgment is reduced, and safety is improved.
Description
Technical field [0001] The invention relates to the technical field of vehicle control, and more specifically, to a pre-braking method based on a recognition mode. In addition, the present invention also relates to a system for realizing the aforementioned pre-braking method based on the recognition mode. Background technique [0002] The braking system of a vehicle is one of the important control systems of a vehicle. The development of vehicle control braking technology determines the technical level of the vehicle. [0003] The braking system of the vehicle in the prior art includes brake braking, manual braking, etc. In the traditional situation, when the driver encounters an emergency, he usually quickly relaxes his right foot on the accelerator, and moves to the brake pedal at the same time. , And depress the brake pedal. When the brake pedal is depressed, the vehicle speed will decrease. During this process, the vehicle speed basically maintains the original vehicle speed. ...
