The module aims is to provide the basic knowledge about the active systems (ABS, TCS, ESC, AWD, ADAS,..) and their role/influence in the vehicle chassis and vehicle dynamic behaviour. T

The student must acquire knowledge about the active systems used in automotive applications, distinguish critically the main architectural solutions, understand the advantages that can be achieved by the adoption of active control systems and their influence on vehicle dynamic behaviour.

The knowledge requested for the present course are related to the subjects presented in the following previous courses: Motor Vehicle Design, Fundamentals of Machine Design & Drawings, Numerical modeling & simulation, Car Body Design & Aerodynamics and Applied Mechanics.

- Linearized models for driver-vehicle interaction: directional and longitudinal control - Layout of main actuation systems and analysis of the components: power steering, brake booster and TMC - Layout of EBD, ABS and ESC control systems - Active braking control: Electronic Brake-force Distribution EBD and Anti-lock Braking System ABS - Active traction control: Traction Control Systems TCS and Anti Spin Regulator ASR - Active handling control: Electronic Stability Control ESC; Vehicle Dynamic Control VDC and Active Roll Control ARC - Emergency braking systems: Brake Assist Systems BAS, EBA, … - Active comfort control: passive and active suspensions - Active suspension: sky hook and ground hook models - Steering control: Active Front Steering AFS and All Wheel Steering AWS - Transmission systems for All Wheel Drive systems AWD - Active differentials - Advanced Driver-Assistance Systems ADAS

The course is organized in 35 hours of Lectures and 15 hours of Laboratory/Practical. Lectures will be held with the support of the blackboard, slides and notes. The documentation used during the lessons will be made available to the students through the website. During the Laboratory classes the students have the possibility to discuss about the assigned project. The practical Laboratory (c/o the FCA Proving Ground) for experimental tests with instrumented car and subjective tests with test engineers will be made.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Progetto di gruppo;

Exam: Written test; Compulsory oral exam; Group project;

... The exam consists of: - Written part is composed by 5 multiple choice questions and 2 open questions. Its maximum evaluation is 30/30. - Oral part made by a project (assigned at the beginning of the course and to do in a group of 2-3 students, chosen from a list given by the professor) and presented to the class and professor during the year. Its maximum evaluation is 33/30. - The final evaluation of the Chassis Design B is the average of the written and oral parts. - The final evaluation of the Chassis Design (global exam) is an average of Chassis Design A and Chassis Design B parts (the two parts must have each a minimal evaluation of 18/30).

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
