As one feasible solution of brake-by-wire systems, electro-hydraulic brake system has been made available into production recently. Electro-hydraulic brake system must work cooperatively with the hydraulic control unit of anti-lock braking system. Due to the mechanical configuration involving electric motor + reduction gear, the electro-hydraulic brake system could be stiffer in contrast to a conventional vacuum booster. That is to say, higher pressure peaks and pressure oscillation could occur during an active anti-lock braking system control. Actually, however, electro-hydraulic brake system and anti-lock braking system are produced by different suppliers considering brake systems already in production. Limited signals and operations of anti-lock braking system could be provided to the supplier of electro-hydraulic brake system. In this work, a master cylinder pressure reduction logic is designed based on speed servo system for active pressure modulation of electro-hydraulic brake system under the anti-lock braking system–triggered situation. The pressure reduction logic comprises of model-based friction compensation, feedforward and double closed-loop feedback control. The pressure closed-loop is designed as the outer loop, and the motor rotation speed closed-loop is drawn into the inner loop of feedback control. The effectiveness of the proposed controller is validated by vehicle experiment in typical braking situations. The results show that the controller remains stable against parameter uncertainties in extreme condition such as low temperature and mismatch of friction model. In contrast to the previous methods, the comparison results display the improved dynamic cooperative performance of electro-hydraulic brake system and anti-lock braking system and robustness.

The primary goal of this work is to implement a clutch and brake system on the single tire Terramechanics rig of Advanced Vehicle Dynamics Laboratory (AVDL) at Virginia Tech. This test rig was designed and built to study the performance of tires in off-road conditions on surfaces such as soil, sand, and ice. Understanding the braking performance of tires is crucial, especially for terrains like ice, which has a low coefficient of friction. Also, rolling resistance is one of the important aspects affecting the tractive performance of a vehicle and its fuel consumption. Investigating these experimentally will help improve tire models performance. The current configuration of the test rig does not have braking and free rolling capabilities. This study involves modifications on the rig to enable free rolling testing when the clutch is disengaged and to allow braking when the clutch is engaged and the brake applied. The first part of this work involves the design and fabrication of a clutch system that would not require major changes in the setup of the test rig; this includes selecting the appropriate clutch that would meet the torque requirement, the size that would fit in the space available, and the capability to be remotely operated. The test rig’s carriage has to be modified in order to fit a pneumatic clutch, its adapter, a new transmission shaft, and the mounting frame for the clutch system. The components of the actuation system consisting of pneumatic lines, the pressure regulator, valves, etc., have to be installed. Easy operation of the clutch from a remote location is enabled through the installation of a solenoid valve. The second part of this work is to design, fabricate, and install a braking system. The main task is to design a customized braking system that satisfies the various physical and functions constraints of the current configuration of the Terramechanics rig. Some other tasks are: design and fabrication of a customized rotor, selection of a suitable caliper, and design and fabrication of a customized mounting bracket for the caliper. A hydraulic actuation system is selected, since it is suitable for this configuration and enables remote operation of the brake. Finally, the rig is calibrated for the new testing configurations.

The article discusses technical solutions for the creation of an effective design of a brake system for high-speed longwheelbase platforms intended for the transport of containers, as well as for the development of a fundamentally new brake equipment for the pneumatic, electro-pneumatic and mechanical parts of the brake system. Modular braking equipment for the pneumatic and electro-pneumatic parts of the high-speed platform braking system, compactly located under the platform frame, provides technical compatibility when controlling platform brakes as part of not only a high-speed freight train of permanent formation, but also in trains for other purposes, regardless of the location of the platform in the composition of the train. The performance of the braking equipment of each platform in motion and in the parking lot is monitored using pressure sensors and an electronic unit that processes the readings of the sensors and transmits information to the locomotive via one of the wire lines of the electro-pneumatic brake. The brake rigging used on the high-speed platform is arranged in the design of three-axle bogies and provides doublesided pressing on the wheels with typical composite brake pads, automatic regulation and maintenance of the standard clearances between brake pads and wheels. The proposed promising technical solutions make it possible to continuously diagnose the parameters of the brakes of each platform as part of a permanent train, display them on the locomotive monitor and transmit them to the dispatch centers of the Russian Railways infrastructure. Thanks to this, the braking effciency can be increased and the safety of train traffc can be ensured while increasing the permissible travel speeds. In the modern concept of digitalization of the infrastructure of Russian Railways, which provides for the creation in 2021–2025 (and in the future until 2030) of cars in which intelligent technologies should be applied, the braking system of a high-speed platform can be considered as the basis for creating a digitally controlled train — one of the key elements of the digital railway.

Braking Process

Penelitian ini bertujuan untukmenemukan hubungan keterikatan antara parameter utama kinematik yang terdapat pada proses pengereman yaitu gaya, jarak dan waktu pada proses pengereman. Perbedaan pola dan karakteristik dari proses pengereman pada kendaraan dinilai sangat penting untuk diketahui disebabkan sistem rem merupakan sistem yang mempunyai peran besar terhadap keamanan dalam berkendara. Yang kemudian hasil penelitian menunjukan bahwa parameter gaya berbanding terbalik terhadap jarak dan waktu pengereman ( gaya >< jarak dan waktu). Sehingga kesimpulan utama dari hasil penelitian adalah karateristik pada proses pengereman mempunyai kecenderungan yang tidak jauh berbeda tetapi memiliki perubahan jarak dan waktu pengereman yang dapat berubah ubah pada setiap variasi gaya yang diberikan pada saat sebelum dan setelah sistem rem pada kendaraan diperbaiki. This study aims to find relationship amongst the main kinematic parameters in braking process, namely force, distance and time. The difference in patterns and characteristics of braking process of vehicles is considered very important to know because braking system constitutes a system that has a large role in safety driving. The results of the study showed the force parameters were inversely proportional to the distance and braking time (force > <distance and time). Therefore, the main conclusion of the study was the characteristics of braking process had a tendency which was not much different but gave a change in distance and braking time which could be different in each variation of force before and after the brake system in repaired vehicles.

One of the physical problems that can be found in heat transfer is heat transfer to a vehicle brake. In this study a focused vehicle is a motorcycle. Where the heat transfer of the brake system on the motorcycle in this study was completed finite element method. The purpose of this study is to analyse one of the problems of displacement in the three dimensions of the motorcycle brake. So, the results obtained in the form of the best time in the braking for motorcycles. The settlement method is to use one of the partial differential equations for heat transfer. One of them is the Elemenisation model is the braking system. As is known braking system is a system used to slow and stop the vehicle. During the braking phase, the vehicle's kinetic energy will be converted into heat energy due to the friction action of the brake system. The heat flux produced by effects to the brake lining is ideally dissipated into the environment to avoid brake friction pad emissions. The heat produced has a tendency to evaporate the brake fluid and the disc brake surfaces will become hot. Based on the results obtained, when the braking system is in operation, the most significant heat transfer in t = 3.8s. This time is the best time to avoid excessive brake fluid evaporation and the rapid breakdown of the brake surface due to excessive heat.
