Electric-control braking device for car and working method thereof

Abstract

The invention discloses an electric-control braking device for a car. The electric-control braking device comprises a first supporting surface, a second supporting surface and a braking motor, whereinthe first supporting surface is provided with a braking switch and a first pedal bracket; the second supporting surface is provided with a braking system, a guiding wheel and a fixed part; a brakingpull rope is connected with a rotary-shaft traction end of the braking motor; the braking motor is controlled to be started or stopped by a control system of the car; the control system of the car isconnected with a sensor. The electric-control braking device disclosed by the invention has the beneficial effects that the design is simple and reasonable; when emergent braking is needed due to suddenly-changed road conditions or other emergencies, if a driver can not take corresponding measures in time, the electric-control braking system can intervene automatically, the braking pull rope is pulled by the braking motor, a braking pedal is driven to move by action of a flexible shaft, the guiding wheel and a second pedal bracket so as to form a braking force, and after the braking is eliminated, an auxiliary braking system returns into a monitoring state again automatically, so that the driving accidents are prevented and the operating safety of the car is ensured.

Description

technical field [0001] The invention belongs to the technical field of safe driving, and in particular relates to a brake system of an automobile, more specifically to an electric brake device for automobiles and a working method thereof. Background technique [0002] At present, traffic accidents occur frequently due to the negligence of drivers. In the process of driving, due to the driver's inattention or misjudgment of the target in front, the vehicle brakes not in time, and the traffic accidents caused by rear-end collision or collision with the vehicle in front occur from time to time. Today, with the development of intelligent control electronic technology, more and more safety assistance driving systems have been applied in automobiles. Through sensors to perceive the environment and vehicle status, the system intervenes in time to control the driving of the vehicle, ensuring the safety of driving. Contents of the invention [0003] In order to overcome the above...
