The fast development of new technologies in autonomous and electric vehicles requires these vehicles’ functional sub-systems to be more reliable. Braking control is one of the most vital systems equipped on these vehicles. Any failure of the braking control system during the vehicle lifetime may lead to fatal consequences. In addition to the safety requirements, it is crucial to fit this system in a restricted space by making it smaller and lighter, while maintaining a cost-effective design. Integrating the hydraulic actuation, boosting, and electrical control functions into one reliable product, called Integrated Brake Control (IBC), has created a variety of technical challenges. One of the biggest hurdles of the IBC design and industrialization is how to produce reliable threaded joints to interconnect the multifunctional components. This research develops a practical torqueing method to manufacture reliable threaded joints which will be able to tolerate very harsh environmental working conditions during the designed life. This presentation summarizes the methods and processes used to produce the reliable threaded joints to interconnect the functional components. Practical examples are demonstrated in this presentation. The method developed in this research can also be applied to other complicated threaded joint applications with harsh working conditions.
