Description

Technical Field

[0001] This utility model relates to the field of brake pedals, and in particular to a brake-by-wire pedal. Background Technology

[0002] The brake pedal is a key component in the motor vehicle driving control system. Its main function is to decelerate or stop the vehicle. The brake pedal is usually made of metal or high-strength plastic and has a certain length and width to facilitate the driver's operation. Underneath the pedal, there is usually a return spring. When the driver releases the pedal, the return spring can return the pedal to its initial position.

[0003] The brake pedal is connected to the vehicle's braking system via mechanical or hydraulic connecting components. However, current brake pedals, after being connected to the vehicle's braking system via mechanical or hydraulic connecting components, have poor sensing effect during braking, making it difficult to quickly sense and transmit braking information from the foot pedal, thus reducing braking effectiveness. To address this issue, we propose a brake-by-wire pedal to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

Simultaneously, a simulator mounting slot allows for the installation of a pedal force simulator. Furthermore, a second coaxial sensor assembly and a first coaxial sensor assembly are installed on the left and right sides of the base. Through the installation of the second and second coaxial sensor assemblies and the setup of the pedal force simulator, braking simulation can be performed, and braking information from the foot pedal can be sensed and transmitted, thereby achieving a brake-by-wire effect and improving the sensing effect during braking.

The pedal force simulator 6 mainly achieves force feedback function based on the coordinated work of sensors and actuators. When the driver presses the pedal, the pedal force simulator 6 detects the displacement information of the pedal and transmits it to the control system. The control system calculates the corresponding simulated resistance value according to the preset algorithm and vehicle operating parameters. A pedal arm groove 7 is provided on the front of the base 1, and a through hole 8 is provided on the inner wall of the pedal arm groove 7.

The multiple mounting holes 10 facilitate the installation of the base 1.

[0028] The working principle of this utility model is as follows: First, the pedal arm assembly 2 is taken out and installed inside the pedal arm groove 7. Then, the rotating shaft 9 is taken out and passed through the pedal arm groove 7 and the through hole 8. Then, the pedal force simulator 6 is installed inside the simulator mounting slot 5.
