1. 1. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gianmarco Grandi; [2023]
   Nyckelord :LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

   Sammanfattning : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

3. 2. Evaluation of Active Rear Steering through Multi-Body Simulation

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Matteo Rossi; Gabriele Bertoli; [2021]
   Nyckelord :Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

   Sammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

4. 3. Investigation of the comfort improvements by an integrated chassis control strategy

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Zhaohui Ge; [2021]
   Nyckelord :comfort; active suspension; active anti-roll bar; active rear-wheel steering; torque vectoring; model predictive control; komfort; aktiv fjädring; aktiv krängningshämmare; aktiv bakhjulsstyrning; drivmomentvektorisering; modellprediktiv reglering;

   Sammanfattning : Autonomous driving is one of the megatrends in today’s automotive industry. Passengers are expected to do more non-driving tasks in an autonomous driving vehicle. Therefore, the comfort of the vehicle has become a more important factor for the passengers. LÄS MER

5. 4. Traction Control of a Three-Wheeled Electric Motorcycle

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Josef Nilsson; Henrik Sandstedt; [2021]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Traction control is a widely used control system to increase stability and safety of four-wheeled vehicles. The company OMotion AB develops and builds threewheeled electric vehicles. With a new model in development they want to increase the safety. LÄS MER

7. 5. Development of a new concept for a v-stay in a heavy vehicle using dynamic analyses

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Författare :Lisa Hansson; Mikaela Johansson; [2021]
   Nyckelord :Heavy vehicle; high capacity transport; dynamic stability; wheel suspension; v-stay; dynamic analysis;

   Sammanfattning : Society of today is struggling with both large amounts of emissions as well as congestion on the roads. For this reason, AFRY in collaboration with Volvo GTT is working on develop and implement longer and heavier transports in traffic network. These combinations are called high capacity transport and have high performance-based demands. LÄS MER
