The proper amount of braking force on both wheels is needed to optimize the braking performance and stability of the motorcycle. The braking effectiveness can be maximized by keeping the ideal nonlinear brake force distribution during braking. Thus the purpose of this research is to present a mechanism that can be accommodated as a Concurrent Brake Actuator (CBA) design to control the ideal nonlinear brake force distribution. In this paper, the conceptual design of the CBA mechanism is developed to be used as a based design for CBA development. Thus, two conceptual designs of the CBA mechanism have been generated. The proposed concept designs were evaluated based on Design Failure Mode and Effect Analysis (DFMEA) and SOLIDWORKS Motion Analysis. The potential failure of the CBA concept design was determined based on the risk priority number (RPN) in DFMEA. The information obtained from DFMEA was used in SOLIDWORKS Motion Analysis to identify stress performance analysis for each CBA conceptual design. Then, the best CBA concept design will be selected. The selection was made based on the highest score gained by the CBA concept design in qualitative evaluation. Based on the results, the fixed main body design with a tilted position linear slope in CBA Design I is potentially to actuate and distribute the nonlinear brake force to the front and rear brake with less potential of failure. Therefore, the proposed mechanism design will be used as a based mechanism design for CBA development.

The Ideal

The article defines the ideal distribution of brake forces between the axles of two-axle utility vehicle when braking. As an evaluation criterion of the selected indicator was the coefficient of stability. It is established that with increase of deceleration of the vehicle axle when the service brake applications, the braking force at the front axle decreases

The Ideal

For tractor-semitrailer, load transfer during cornering braking caused big difference of the vertical load between coaxial wheels. As a result, braking efficiency and directional stability were affected seriously, the traditional design of braking force distribution between axles couldnt meet the requirements. In this paper, a dynamic model of tractor-semitrailer was established according to the motion and force during cornering braking. The rule of vertical load changing of each wheel with longitudinal acceleration and lateral acceleration was obtained. Combining with the tire and road adhesion conditions, the ideal brake force distribution was achieved. The research could provide theoretical reference to better control strategy of tractor-semitrailer braking control system.

Brake Force Distribution

Within the field of electric vehicles, the cooperative control of a dual electro-hydraulic regenerative brake system using the foot brake pedal as the sole input of driver brake requests is a challenging control problem, especially when the electro-hydraulic brake system features on/off solenoid valves which are widely used in the automotive industry. This type of hydraulic actuator is hard to use to perform a fine brake pressure regulation. Thus, this paper focuses on the implementation of a novel controller design for a dual electro-hydraulic regenerative brake system featuring on/off solenoid valves which track an “ideal” brake force distribution. As an improvement to a standard brake force distribution, it can provide the reach of the maximum braking adherence and can improve the energy recovery of a rear-wheel-drive electric vehicle. This improvement in energy recovery is possible with the complete substitution of the rear hydraulic brake force with a regenerative brake force until the reach of the electric powertrain constraints. It is done by performing a proper brake pressure fine regulation through the proposed variable structure control of the on/off solenoid valves provided by the hydraulic platform of the vehicle stability system. Through road tests, the tracking feasibility of the proposed brake force distribution with the mechatronic system developed is validated.
