Abstract

The aim of this research is to contribute to the development of automatic braking assistance systems
for vehicles, imitating human behaviour, but minimizing certain errors such as distraction or reaction time. For this purpose, a strain gauge sensor is installed on the clamp rod of a vehicle front axle disc brake, whose signal is directly related to the braking force or braking torque and can therefore be used as a measurement variable to control and regulate the brake. This paper presents the design of an artificial neural network-based estimator of the deformation of the clamp rod of the brake caliper when the vehicle brakes. The proposed system is capable of optimising the braking intensity according to the distance available to perform the manoeuvre and the vehicle speed, trying to be as unaggressive as possible, thus prioritising the comfort of the occupants. The simulations carried out have validated the proposed method for estimating the braking force of a vehicle in real deceleration scenarios.
