Problems solved by technology

[0002] When a novice driver is driving an electric vehicle, due to his insensitivity to the vehicle speed and the distance to the vehicle in front, the pedal opening of the brake pedal is not enough, or in a hurry, the accelerator pedal is mistakenly stepped on as the brake pedal, which leads to Rear-end accidents seriously threaten driving safety
Existing electric vehicles generally achieve emergency braking through hydraulic braking and anti-lock braking systems associated with the brake pedal, and electronic parking that is manually opened, which cannot meet the driving needs of novice drivers

Embodiment Construction

[0017] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, so that those skilled in the art can refer to the description text and implement accordingly.

[0018] It should be understood that terms such as "having", "comprising" and "including" as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0019] like figure 1 As shown, the present invention provides an electric vehicle emergency braking identification and control method, including:

[0020] S101. Obtain the steering wheel angular velocity ω and the distance d from the preceding vehicle of the electric vehicle.

[0021] Specifically, the distance d from the vehicle in front can be measured by a millimeter-wave radar provided on the electric vehicle.

[0022] S102, determine whether the steering wheel angular velocity ω is equal to 0, and whether the distance d from the preceding vehicle is...

Abstract

The invention discloses a method for identifying and controlling emergency braking of an electric vehicle. Braking signal: According to the emergency braking signal, the opening degree of the brake pedal and the wheel load, the braking force of the wheel is adjusted to realize emergency braking. The emergency braking identification and control method of the electric vehicle of the present invention effectively avoids rear-end collisions caused by insufficient opening of the brake pedal or accidentally depressing the accelerator pedal, thereby improving the driving safety of the electric vehicle.

Description

technical field [0001] The invention relates to the field of emergency braking of electric vehicles. More specifically, the present invention relates to an electric vehicle emergency braking identification and control method. Background technique [0002] When a novice driver is driving an electric vehicle, due to insensitivity to the speed of the vehicle and the distance from the vehicle in front, the brake pedal is not pressed enough, or in a hurry, the accelerator pedal is used as the brake pedal by mistake, which leads to A rear-end collision is a serious threat to driving safety. Existing electric vehicles generally implement emergency braking through hydraulic braking and anti-lock braking system braking associated with the brake pedal, as well as manually activated electronic parking, which cannot meet the driving needs of novice drivers. SUMMARY OF THE INVENTION [0003] One object of the present invention is to provide an emergency braking identification and con...
