Problems solved by technology

[0003] The purpose of the present invention is to provide an electronically controlled braking and parking integrated system applied to automatic driving, so as to solve the problem that the braking and parking used by manual driving in the above-mentioned background technology are operated separately. When the car is stationary, the parking brake is applied. This kind of braking is realized linearly, which is better for the experience of the occupants. However, when this traditional braking method is used for automatic driving, it shows its shortcomings, especially When it is an unmanned logistics vehicle or a sales vehicle, because there is no one on the vehicle, we do not need to consider the human experience

Abstract

The invention discloses an electronic control type braking and parking integrated system applied to automatic driving, a braking and parking instruction is received, and after a radar system monitors that an obstacle exists in the advancing direction, or a remote control system receives the braking and parking instruction, the instruction is transmitted to an electric vehicle central controller; a hub motor rotates in the reverse torque direction after receiving the braking and parking instruction, and the hub motor rotates in the reverse torque direction after receiving the braking and parking instruction; after the brake pad brakes and a brake cylinder hydraulic system is started, the hydraulic cylinder is pneumatic, hydraulic oil is pushed to enter the brake disc, and the brake pad is pushed to stop the hub. The problems that braking and parking used for manual driving are operated separately, braking is completed firstly, parking braking is conducted when a vehicle is static, braking is achieved linearly, experience of passengers is good, but the traditional braking mode shows the defects when used for automatic driving, especially for unmanned logistics vehicles or selling vehicles due to the fact that no one is on the vehicle can be solved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electronically controlled braking and parking integrated system applied to automatic driving. Background technique [0002] With the development of the automobile industry, automatic driving pays more and more attention to the safety and speed of braking, and the integrated and miniaturized braking structure is also constantly improving. Most of the existing vehicles, especially electric vehicles, use traditional The mechanical system has a complex structure and requires space layout during installation. In the development of small cars, new energy vehicles and various miniature self-driving platforms, the present invention can simplify these, combine braking and parking into one, abandon mechanical braking, and adopt electronically controlled hydraulic push rod transmission , simplifies the operation of braking and parking, and is conducive to realizing the light weight of t...
