Design of an Electronic Brake Pedal
(2010) MMKM01 20101Innovation
- Abstract
- The final purpose of this project is to create a platform that leads to the improvement of the braking feeling by the users of heavy vehicles. The complexity of the problem lays on the different constraints: geometrical and functional, and as well on the interaction with a human operator.
The task is to design a new electronic brake pedal, with the possibility to change the relationship between force feedback to the user and pedal stroke. The new assembly must fit in available space in the truck's cabin.
The approach taken considered, at first, a modeling stage of the situation in hand. That includes geometrical and functional constraints, such as length and torque.

The task is to design a new electronic brake pedal, with the possibility to change the relationship between force feedback to the user and pedal stroke. The new assembly must fit in available space in the truck's cabin.
The approach taken considered, at first, a modeling stage of the situation in hand. That includes geometrical and functional constraints, such as length and torque. When the components were chosen based on the dynamics and kinetics, the assembly was modeled in 3D specialized software (ProEngineer). An introduction to Haptics is included, as this project is related to this field. Finally, it was assembled physically.
The result was a portable, resistant and functional assembly that can be used to test different pedal feelings in the driver. The assembly was not set to operation due to time limitations. The final product includes a servomotor that can provide up to 2 Nm and a ball screw to convert rotary to linear motion, as to push the pedal and therefore create the force feedback required. A control law was proposed and simulated, showing that the motor could require twice as much current as the current for continuous operation shown in the manufacturer's data, for a short period of time.
The motor assembly, particularly the controller, shows a great potential to control the motor operation in a flexible way. A major conclusion is that force applied by the user should be the variable tracked in the final version of the assembly. The proposed solution could be too expensive for commercial application.
