“…In the steering and drive system of an ECO motor car, the function of direction controller is conducted by the steering wheel of SBW system, whereas, the function of speed and torque controllerby pedal or joystick of ED system. At the present moment, the research results are known and the first applications of both SBW systems [2], [9], [28], and ED systems [7], [16], [10], [23], [27] have already been used. Fig 4. presents two basic structures of velocity control used in vehicles with rear wheel drive: a) with direct presetting of two speeds, b) with speed difference presetting.…”
