Abstract

To safely control any automobile, brake system plays a crucial role. Brake system performance defines the driver’s confidence in handling the vehicle at different speeds on all terrains. So, it becomes important to understand the underlying dynamics to decide braking requirements of a vehicle. Brake performance is affected by several parameters. Performance is predicted by mathematical modelling using vehicle and brake parameters. Physical measurements of brake performance at vehicle level mostly yield values that vary from predicted. These variations are caused by multiple parameters like tolerances, tyre-road adhesion, environmental conditions and human reaction times. Literature study shows the brake calculations to finalize either front or rear brake sizes and thermal stress analysis on brake parts during braking. There are no studies to understand the discrepancies between calculations and the test results. This paper aims to provide a brake system design methodology and study the influence of brake part, vehicle parameter tolerances, and braking reaction time upon the vehicle brake performance. Attempt is made to establish tolerance bandwidth for major performance parameters like deceleration and stopping distance particularly for hydraulic brake systems. Further major contributing factors of brake performance variation are identified, and their percentage contribution is quantified. In the case of critical situations like homologation compliance, ensuring these major contributing factors at the nominal values yields results that are close to predicted.
