Description:Dual-Mode Continuous Braking System with Electric and Hydraulic Controls
Field of the Invention
[0001] The present disclosure generally relates to autonomous vehicle braking systems. Further, the present disclosure particularly relates to a dual-mode braking system combining electric and hydraulic braking.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] The present disclosure generally pertains to braking systems for autonomous vehicles, specifically systems integrating electric and hydraulic braking methods to enable stable braking performance under varying operational conditions. In recent years, autonomous vehicles have gained prominence in the transportation sector, necessitating reliable and adaptable braking systems for continuous operation. Conventional braking systems generally fall under electric braking, hydraulic braking, or a combination of both. However, existing systems are often limited in adaptability and reliability due to the challenges associated with managing transitions between electric and hydraulic braking under different operational requirements.
[0004] Electric braking systems utilise motor-generated braking force to reduce or stop vehicle motion. Electric braking techniques are commonly valued for their immediate response and energy efficiency, as they may contribute to regenerative braking, enabling partial energy recovery. However, such systems often face limitations in braking performance under certain conditions, such as high-speed braking or scenarios requiring extended braking duration, where electric braking alone may be insufficient. Moreover, electric braking systems can be prone to efficiency loss and overheating during prolonged operation, posing risks to the vehicle's performance in demanding situations. Therefore, electric-only systems generally require complementary braking mechanisms to provide a comprehensive braking response across a range of conditions.
[0005] Hydraulic braking systems, on the other hand, employ fluid compression to generate braking force. These systems are typically recognised for their reliability in providing consistent braking power and are extensively used in applications requiring sustained braking strength. Hydraulic braking enables effective braking control for heavier loads and high-speed conditions. However, such systems are often limited by response times when initiating braking. Hydraulic systems generally require pressure buildup to exert braking force, resulting in potential lag that may impede braking efficiency in rapid-response scenarios. Furthermore, hydraulic braking systems face constraints in energy recovery, as such systems do not contribute to regenerative braking, resulting in reduced energy efficiency compared to electric systems.
[0006] Due to these individual limitations, braking systems that combine electric and hydraulic components have been proposed in the prior art to leverage the strengths of both methods. Hybrid braking systems that combine electric and hydraulic braking seek to provide comprehensive braking performance by using electric braking for initial, quick-response braking and transitioning to hydraulic braking for sustained braking power. However, existing hybrid systems often lack precise management of transitions between electric and hydraulic braking, leading to abrupt changes in braking force. Such abrupt transitions may compromise vehicle stability, particularly in autonomous vehicles where braking control is critical to navigating various environments autonomously. Additionally, such systems may exhibit inefficiency due to suboptimal coordination of electric and hydraulic braking under certain operational conditions, such as rapid acceleration-deceleration sequences or during extended braking intervals.
[0007] Other state-of-the-art braking systems have proposed using complex control algorithms to manage transitions in braking modes. However, the application of control algorithms has introduced additional challenges, including the complexity of programming precise braking responses and the potential for algorithmic errors under certain conditions, leading to reduced braking reliability. Algorithm-based systems further rely on additional computational resources, which may increase the energy consumption and complexity of autonomous vehicle systems overall, creating additional constraints on vehicle design and operation.
[0008] In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for achieving continuous and reliable braking in autonomous vehicles under varying operational conditions.

[00054] In an embodiment, the electric braking unit 108 is aligned in parallel with the hydraulic pump 110, enabling simultaneous or sequential activation of both braking mechanisms within the dual-mode braking system 100. This parallel alignment allows the electric braking unit 108 to engage rapidly for immediate braking response, while the hydraulic pump 110 provides sustained braking power for extended braking needs. The dual activation capability of this configuration supports adaptable braking control, promoting gradual deceleration when both units operate in sequence. This setup enables the braking system to accommodate changing loads effectively and offers precise braking transitions, thereby enhancing braking reliability in complex driving scenarios.
[00055] In an embodiment, the hydraulic pump 110, arranged in fluid communication with the oil compression module 112 via a high-pressure conduit, facilitates seamless hydraulic braking.

The fluid communication setup enhances the response time of hydraulic braking by reducing potential delays in fluid transfer, which is critical in high-demand scenarios. This configuration supports consistent braking pressure, enabling the braking system to perform reliably under prolonged and high-pressure braking events while preventing pressure loss that could reduce braking efficiency.
[00056] In an embodiment, the control module 114, oriented in an integrated sequence with the electric braking unit 108 and hydraulic pump 110, provides synchronized control signals that enable smooth braking transitions. The integrated sequence allows the control module 114 to coordinate braking actions between the electric and hydraulic components, ensuring stable braking without abrupt force changes. This synchronization maintains braking continuity, supporting a unified operational response during dynamic driving conditions. The sequential setup minimizes the risk of braking disruption by adjusting braking distribution as needed, preserving braking effectiveness regardless of shifting operational requirements within the dual-mode braking system 100.
[00057] In an embodiment, the dual-mode braking system 100 includes a resilient mounting assembly that supports the braking gear 106 and absorbs vibrational forces generated during braking operations. This mounting assembly stabilizes engagement between the braking gear 106 and driven gear 102, reducing the impact of mechanical stress on both components. The absorption of vibrational forces minimizes potential misalignment during braking, preserving the consistent engagement of the gears. This setup prolongs the operational life of the braking gear 106 by reducing wear, ensuring sustained braking performance under demanding conditions.
[00058] In an embodiment, the oil compression module 112 includes a temperature-regulation sub-module that actively maintains optimal fluid viscosity during prolonged braking events. The temperature-regulation sub-module prevents fluid overheating, preserving hydraulic fluid integrity and supporting stable hydraulic braking. This setup allows the oil compression module 112 to consistently deliver braking pressure by maintaining fluid viscosity within an optimal range. The temperature-regulation capability of the sub-module ensures that the hydraulic braking response remains effective, preventing performance degradation due to thermal factors, thus maintaining hydraulic efficiency during extended braking operations.
[00059] In an embodiment, the control module 114 incorporates an adaptive feedback loop that continuously monitors wear levels of the braking gear 106 and electric braking unit 108, distributing braking force accordingly to balance component wear. The feedback loop includes sensors that track real-time wear conditions and adjust braking force distribution to prevent premature component failure. This adaptive response maximizes the operational lifespan of braking elements by modulating braking force based on wear status, allowing for consistent braking without overloading specific components within the dual-mode braking system 100.
[00060] In an embodiment, the hydraulic pump 110 features a dual-impeller configuration that enables dual-directional fluid flow to the oil compression module 112, supporting bidirectional braking engagement. This dual-impeller setup provides braking force in both forward and reverse driving scenarios, allowing the braking system to respond effectively regardless of vehicle direction. The dual-directional flow improves braking versatility, ensuring comprehensive braking performance across diverse driving conditions. This configuration maintains fluid pressure consistency, supporting robust braking capability whether the vehicle is moving forward or in reverse.
