Aim of this diploma thesis is to found influence of differential to driveability and vehicle suspension dynamics. In theoretical part of thesis is mentioning about mechanical differentials, their constructions, features and suppression of their weaknesses. In this part are included information about differentials with limited slip, Torsen® diferential and torque vectoring systems. Practical part of thesis is devoted to designing of vehicle model suspension, radio communication, and electric motor controller, flow charts of driving modes and measurement methodics and evaluation of measurements. Model is equipped with double wishbone suspension in front and at back as well. Radio communication working in 2.4GHz range with two transcievers, which one is coupled with PC application working as transmitter and second one is used as receiver in vehicle model. Drivetrain is equipped with motor controller VNH2SP30-E which has integrated double H-bridge on circuit. Result of thesis is operational vehicle suspension model which simulate open diferential, diferential with limited slip and has function of torque vectoring.
