A steering column assembly for an autonomous or semi-autonomous vehicle includes a steering wheel and an upper steering shaft rigidly coupled to the steering wheel. Also included is a lower steering shaft operatively coupled to the upper steering shaft. Further included is a ball coupling assembly comprising balls retained within the upper steering shaft, the balls disposed in a first radial position that engages the balls with the upper steering shaft and the lower steering shaft to place the steering shafts in a coupled condition, the balls disposed in a second radial position that disengages the balls from at least one of the upper steering shaft and the lower steering shaft to place the steering shafts in a decoupled condition.

A detachable steering wheel includes a steering wheel body, an electric sleeve, a fixing mechanism, a controlling module and an identifying module. The steering wheel body includes a direction grip and a connection shaft. The connection shaft is inserted into a steering column. Moreover, plural indentations are formed in the connection shaft. The electric sleeve is movably sheathed around the steering column. The fixing mechanism includes plural rolling balls and plural openings. The plural openings are penetrated through the corresponding openings and connected with the corresponding indentations. The controlling module is installed in the steering column and electrically connected with the electric sleeve. The identifying module is installed in the direction grip and electrically connected with the controlling module. Due to these structures, the intelligent anti-theft purpose is achieved.

A vehicle steering system and a vehicle are provided. The vehicle steering system includes a steering shaft and a steering transmission shaft. The steering shaft or the steering transmission shaft includes a first shaft section and a second shaft section. A clutch mechanism is arranged between the first shaft section and the second shaft section. In an engaging state, a transmission connection is established between the first shaft section and the second shaft section, and in this case, a controller determines that the vehicle enters a driving mode. In a disengaging state, the transmission connection between the first shaft section and the second shaft section is disconnected, and in this case, the controller determines that the vehicle enters a game mode.
