Driverless vehicle with steering wheel

A driverless vehicle, comprising:

• at least one driven wheel;
• a steering linkage assembly coupled to the at least one driven wheels;
• a steering controlling system comprising:
• a steering wheel coupled to the steering linkage assembly, the steering wheel and the steering linage assembly configured for cooperatively changing a turning direction of the driven wheels;
• a plurality of light receivers positioned around an outer side surface of the steering wheel;
• a fixing ring surrounding the steering wheel, and spaced a distance from the steering wheel;
• a plurality of light emitters positioned on an inner surface of the fixing ring, the light emitters being paired with the light receivers and arranged spatially corresponding to the respective light receives, each pair of the light emitter and receiver being aligned with a radially direction of the steering wheel;
• a controller configured for controlling only one of the light emitters to emit light rays each time towards the corresponding light receiver, and
• a processor configured for determining a turning direction of the steering wheel according to a location of a current light receiver which currently receives light rays from the corresponding light emitter and determining a turning angle of the steering wheel according to the location of the current light receiver and a location of a preceding light receiver which receivers light rays from the corresponding light emitter preceding to the current light receiver;
• wherein the steering wheel is configured to steer the driven wheels to turn according to the determined turning direction and the determined turning angle.
