Abstract

The invention discloses an electronic parking structure for an electric automobile. The electronic parking structure comprises a bearing portion, a first base plate, a second base plate, a brake disc,a piston and a power unit; a shell is slidably arranged on the bearing portion, one side of the shell is provided with a caliper, and the other side of the shell is provided with a cylinder body; thefirst base plate and the second base plate are installed on the bearing portion in a mode of being capable of sliding relative to each other, and are located between the caliper and the cylinder body, the first base plate is connected with the caliper, and the second base plate is in contact with the cylinder body; the brake disc is arranged between the first base plate and the second base plate;the piston is of a cup-shaped structure, and is arranged in the cylinder body, and one end of the cup-shaped bottom surface is connected with the second base plate; and the power unit is connected with the piston, and is used for driving the second base plate to move close to or away from the first base plate. The invention further provides a control method of the electronic parking structure forthe electric automobile, parking place road conditions and automobile conditions can be collected, and the working state of the electronic parking structure can be determined based on the BP neural network.

Description

technical field [0001] The present invention relates to an electronic braking system, and more specifically, the present invention relates to an electric vehicle electronic parking structure and a control method thereof. Background technique [0002] With the increase of vehicle ownership, vehicle safety has increasingly become the focus of research. Due to people's carelessness, when parking, they often forget to pull the handbrake, resulting in the car slipping phenomenon, financial losses in light cases, and personal injuries in severe cases. Therefore, existing vehicles will be equipped with electronic parking structures to avoid parking. When driving, if people forget to pull the handbrake, the electronic parking structure will automatically work to realize the stable parking of the vehicle. However, in the process of electronic parking, the phenomenon of unstable parking often occurs, and the vehicle cannot be effectively parked according to real-time road conditions ...
