Purpose and goal
In order to improve braking performance on commercial vehicles a concept for fast actuation brake valve has been developed. Initial tests has shown significant reduction in braking distance can be achieved and thereby improves traffic safety. The need for a fast actuating brake valve is seen as very important to achieve further reduction of vehicle accidents and enable a system set-up which for the future of autonomous driving. The objective is also to ensure a better integration of the brake system in the overall system architecture for vehicle dynamics.
Expected results and effects
A faster control of the brake pressure enables better control of the vehicle dynamics, especially in emergency situations and on slippery road surfaces. The pneumatic brake system of today has a rather high hysteresis in its control which makes it difficult to utilize the maximum available grip between the tyre and the road. A high performing service brake module with a quick response control towards the overall system is expected to give significant better braking performance, stability control and not least support for future function in direction of autonomous driving.
Planned approach and implementation
Haldex will in this project develop next generation of the fast actuating valve technology together with research representatives at Chalmers University and advanced engineering at Volvo GTT. Valve prototypes and control system will be developed to verify the technology maturity level before further development towards serial production. The project will consist of different working packages focusing on HW,SW, failsafe analysis, simulations, prototype build and vehicle testing in relevant environments. Master Thesis and scientific articles will also be included.
