ABSTRACT
ABSTRACT: The brake force distribution between front and rear axles of a vehicle is typically specified such that front and rear wheels operate at the same level of brake force coefficient (normalised forces). It can be shown that this ‘ideal’ distribution is adopted to deliver the maximum vehicle deceleration and minimum braking distance. In subcritical braking scenarios, this distribution may vary to deliver the same deceleration demand. In this work the optimal distribution which minimises the pitch angle is obtained to enhance driver comfort during braking. A novel vehicle model with appropriate consideration of the suspension geometry is developed and employed. We optimize brake force distribution for minimum pitch angle under quasi-static conditions of constant deceleration. Subsequently, a map of vehicle deceleration to brake force distribution is generated. The map as well as ideal distribution are simulated and then implemented on a demonstrator vehicle to prove the effectiveness of the solution.
