Abstract
This work is developed within the framework of the ”Rota 2030” program (Law no. 13,755/2018). Among the objectives of this program is to encourage business R&D in the production of new automotive technologies; which would have a direct impact on the quality of vehicles and parts produced in Brazil, as well as on environmental care. One of the pillars of the ”Rota 2030” is the establishment of mandatory safety requirements for the commercialization of vehicles produced in Brazil or imported. Being consistent with the above, the present work aims to propose an electronic control system (ESC) capable of ensuring vehicle stability and, therefore, passenger safety, in maneuvers on the road. To achieve this objective it was necessary to define three degrees of freedom (3DOF) vehicle model that reflects the behavior of the side-slip angle, yaw rate, and roll angle during a maneuver and then evaluate control strategies capable of maintaining these parameters in a safe range. The obtained 3DOF model contemplates the relation of the steering wheel rotation with the generation of lateral forces by means of the Pacejka Magic Formula (PMF) method. On the other hand, the control strategies are based on a nonlinear PID in the case of yaw rate and side-slip angle control, and on a fuzzy controller in the case of roll angle control. The combination of these control techniques results in strategies for the actuation of brakes and active dampers in order to maintain vehicle stability in the maneuver. At the end of this work, it is obtained the design of an ESC capable of controlling the stability of a car in the performance of abrupt maneuvers maintains the critical parameters of the car in an established safety range. This study means a step forward in the manufacture and implementation of a commercial ESC of Brazilian production for vehicle safety and integrated into the fulfillment of the objectives of the ”Rota 2030”. It provides an effective and economical solution for increasing vehicle safety on Brazilian roads.
