In this thesis the requirements for a rear wheel steering mechanism aimed to be implementedon KTH:s Formula Student car were evaluated. The requirements were obtainedby using already known loads, an analysis of how the quickly the driver turns the steeringwheel during track driving from video material and the Formula Student rulebook whichthe car is designed after. After the requirements were produced a number of concepts wereproduced and evaluated against each other. The concept that was given the highest scorewas a rack and pinion concept with a rotary actuator which was developed further.The design was made by first selecting an actuator with a planetary gearbox that couldfulfill the speed and load requirements and afterwards with CAD a design that could beintegrated on the car was made. The concept weighed around 1,7 kg and was compatiblewith the requirements. / I detta arbete undersöktes kraven som ställs på ett bakhjulsstyrningssystem för implementering på KTH:s Formula Student bil. Kraven togs fram genom att använda redan kända laster, en analys av hur snabbt föraren svänger utifrån videomaterial samt regelboken som alla formulastudentbilar är konstruerade efter. Efter att kraven tagits fram utvärderades ett antal koncept där det bästa konceptet, kuggstångsmekanism med ett roterande ställdon utvecklades vidare. Prototypdesignen gjordes genom att först välja ett ställdon med planetväxellåda som skulle klara av kraven och därefter med hjälp av CAD skapa en integrerbar design. Det färdiga konceptet väger ca 1,7 kg och klarar alla ställda krav.
