Braking System Modeling and Brake Temperature Response to Repeated Cycle

Abstract

Braking safety is crucial while driving the passenger or commercial vehicles. Large amount of kinetic energy is absorbed by four brakes fitted in the vehicle. If the braking system fails to work, road accident could happen and may result in death. This research aims to model braking system together with vehicle in Matlab/Simulink software and measure actual brake temperature. First, brake characteristic and vehicle dynamic model were generated to estimate friction force and dissipated heat. Next, Arduino based prototype brake temperature monitoring was developed and tested on the road. From the experiment, it was found that brake temperature tends to increase steadily in long repeated deceleration and acceleration cycle.

Development of a Model for Predicting Brake Friction Lining Thickness and Brake Temperature

“…Out of the total energy absorbed during braking, some of the energy is also dissipated at road-tire interface. x is fraction of energy absorbed by brakes (Dalimus, 2014).…”

“…In the study titled 'braking system modeling and brake temperature response to repeated cycle', brake characteristic and vehicle dynamic model was generated in MATLAB/Simulink software to estimate friction force and dissipated heat. Furthermore, Arduino-based prototype brake temperature monitoring was developed and tested on the road (Dalimus, 2014). In another paper, the effect of contact force and friction radius is studied with varying conditions of parameters; longitudinal force, caliper force, and torque on piston side as well as non-piston side by using Matlab/Simulink models for drum & disc brakes (Khairnar, Phalle & Mantha, 2016).…”

Clamping-Force Control of a Sensor-less Electro-Mechanical Brake Actuator in New-Energy Vehicles

“…Sensored EMB systems are not suitable for practical use, however, as braking systems undergo harsh thermal and shock conditions. Brake pads on heavy trucks and performance vehicles frequently reach 500 degrees Celsius during heavy braking [3], and heavy vehicles are often equipped with water cooling systems to rapidly reduce brake temperatures. Delicate electronics such as pressure sensors might not be able to operate under such high temperatures and dramatic thermal cycles, and their long-term reliability cannot be guaranteed.…”

“…Almost all road-going vehicles are equipped with power-assisted braking systems [1][2][3][4][5] where the operator's pedal movement is amplified to generate a sufficient braking force. On ICE (Internal Combustion Engine) vehicles with hydraulic braking systems, this is achieved by means of a vacuum booster, that is powered either by the vacuum generated by the combustion engine's air intake, or by a vacuum pump connected to the engine's accessory pulley.…”

Modeling and design of cooperative braking in electric and hybrid vehicles using induction machine and hydraulic brake

“…The kinetic energy is transformed into heat energy through the process of friction between the two surfaces in contact in the brake; the rotor and the stator. A conventional braking system has been modeled, and it was confirmed through experiment that energy loss during braking appeared in a rear drummed brake temperature rise [1]. Meanwhile, a hybrid electric vehicle allows the kinetic energy to be converted into electrical energy using an electric Motor/Generator (M/G), stored in a battery or an ultra-capacitor and subsequently returned to the M/G, and this is known as regenerative braking.…”
