Motor-controlled linear control brake device for unmanned vehicle

Abstract

The invention discloses a motor-controlled linear control brake device for an unmanned vehicle. The motor-controlled linear control brake device comprises a servo assembly, a linear motion assembly, apiston pump, a pressure transmitter, a pedal assembly and a push rod module, wherein the servo assembly is connected with the linear motion assembly, the linear motion assembly is connected with thepiston pump through a tension part and a force receiving part, the piston pump is in communication with the pressure transmitter, the piston pump is connected with the push rod module through the pedal assembly, and the push rod module is used for emergency braking. According to the motor-controlled linear control brake device, emergency braking can be realized, refitting is convenient, and the braking sliding distance is shortened.

Description

technical field [0001] The invention relates to the technical field of braking devices, in particular to a motor-controlled linear control braking device for unmanned vehicles. Background technique [0002] In unmanned autonomous vehicles, the braking system is an extremely important component. During the operation of unmanned self-driving vehicles, it is necessary for the vehicle to automatically decelerate, brake, and stop quickly through the motor-controlled linear braking structure according to various emergencies encountered on the road under the condition of unmanned automatic driving, so as to ensure The safety and reliability of the vehicle during driving. [0003] The braking system of unmanned vehicles on the existing market is either that the vehicle itself has its own braking device and then installs an electromagnetic braking device or uses a motor with a brake function for braking. This method has the following disadvantages: 1. It is difficult to modify the ...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. It is difficult to modify the unmanned vehicle; 2. It cannot be linearly controlled, and different braking effects can be achieved with different forces; 3. It cannot be switched with the vehicle's own brake at will; 4. .Unable to form a closed-loop feedback on oil pressure changes after braking; 5. Unable to self-lock to maintain vehicle status when the vehicle is powered off; 6. Automatic braking accuracy control is not ideal; 7. Slow braking response results in long sliding distance; 8. Braking effect judgment has photoelectric and displacement sensor failure risk
