2. 1. Distributed Road Grade Estimation for Heavy Duty Vehicles

   Author : Per Sahlholm; Karl Henrik Johansson; Emilio Frazzoli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; estimation; distributed systems; automatic control; heavy duty vehicles; road grade; road maps; Automatic control; Reglerteknik;

   Abstract : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. READ MORE

4. 2. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

   Author : Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

   Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

5. 3. Fuel-efficient driving strategies

   Author : Sina Torabi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed profile optimization; fuel efficiency; neural networks.; energy efficiency; genetic algorithms; performance analysis; road grade estimation; mass estimation; vehicle platooning;

   Abstract : This thesis is concerned with fuel-efficient driving strategies for vehicles driving on roads with varying topography, as well as estimation of road grade and vehicle mass for vehicles utilizing such strategies. A framework referred to as speed profile optimization (SPO), is introduced for reducing the fuel or energy consumption of single vehicles (equipped with either combustion or electric engines) and platoons of several vehicles.

6. 4. Fuel-Efficient Heavy-Duty Vehicle Platooning

   Author : Assad Alam; Karl H. Johansson; Roberto Horowitz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Heavy-Duty Vehicle; Optimal Control; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The freight transport industry faces big challenges as the demand for transport and fuel prices are steadily increasing, whereas the environmental impact needs to be significantly reduced. Heavy-duty vehicle (HDV) platooning is a promising technology for a sustainable transportation system. READ MORE

7. 5. Runtime Monitoring for Safe Automated Driving Systems

   Author : Ayhan Mehmed; Sasikumar Punnekkat; Michael Paulitsch; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

   Abstract : Mass-produced passenger vehicles are one of the greatest inventions of the 20th century that significantly changed human lives. Several safety measures such as traffic signs, traffic lights, mandatory driver education, seat belts, airbags, and anti-lock braking systems were introduced throughout the years. READ MORE
