Control functions based on brake actuators in combination with other actuators in new vehicles.

by Anton Zakariasson

Todays automotive industry evolves very quickly and new technology is integrated into vehicles every day. This technology creates many new actuator-controlled functions and sub-functions having different names and use in every car makers program. The thesis has been performed at F Industry chassis department in Trollhttan, Sweden. To get a clear overview and understanding, a benchmarking process have been made for a classic station wagon to sort out and categorize functions for five different car makers. The same process for another car model was also made parallel to this thesis by another student for wider results, while this thesis covers brake actuators and brake actuators in combination with other actuators that student covers other types of actuators. These benchmarking results were then put together and a screening was done to eliminate functions not relevant for my thesis. The remaining functions were analyzed more in depth and a datasheet was created for each function covering basics such as its functions, how it works, pros and cons, parameters and an estimated cost. This will be used for clarifying the functions for Fs engineers when needed. Evaluation of the function Electronic Stability Programme (ESP) was also done through testing at NEVS test track in Trollhttan with advanced and accurate test equipment. The ESP evaluated by a standardized test method SS-ISO 3888-2, Severe lane-change maneuver Part 2: Obstacle avoidance where the track was completed in various speeds with ESP activated and ESP deactivated. By having ESP activated, control of the vehicle was gained and skidding was repealed. The results did not show off a great difference but there were clear signs and data that the ESP affected the vehicle in a positive way. Dagens fordonsindustri utvecklas i ett rasande tempo dr det kommer ny integrerande teknik varje dag som baseras p aktuatorer (stlldon). Denna teknik skapar mnga nya aktuatorbaserade funktioner och sub-funktioner som alla har olika benmningar och anvndningsomrde inom varje biltillverkares utbud. Arbetet har utfrts hos F Industry chassiavdelningen i Trollhttan, Sverige Fr att f en tydlig verblick och fr att skapa frstelse, s har en benchmarking-process genomfrts fr en klassisk herrgrdsvagn fr att sortera och kategorisera fem olika biltillverkares funktioner. Samma process har ven genomfrts parallellt av en annan student fr bredare resultat. Detta arbete tcker funktioner som r baserade p bromsaktuatorer och bromsaktuatorer i kombination med andra aktuatorer medan den andra studentens arbete tcker andra sorters aktuatorer. Resultatet frn bdas benchmarking lades ihop och en sllning gjordes fr att avlgsna irrelevanta funktioner fr denna rapport. De kvarvarande funktionerna analyserades mer p djupet och ett faktablad skapades dr funktion, hur den fungerar, fr- och nackdelar, parametrar och pris tcktes. Dessa kommer att anvndas nr Fs ingenjrer r oskra p vad det r fr funktion och hur den fungerar. Utvrdering av
