The invention discloses a driving assistance system based on artificial intelligence, which relates to the technical field of driving assistance systems and comprises a throttle lever. A piezoresistoris fixedly connected to the middle of the throttle lever, and a negative plate electrically connected with the piezoresistor is fixedly connected to the inner wall of the throttle lever. According tothe driving assistance system based on artificial intelligence, a limiting block and a limiting groove are matched for use, in an initial state, the rotating block can be fixed at a specific positionunder the action of the torsional spring, the limiting block is clamped with the limiting groove, the rotating block and the mounting cylinder are relatively fixed, at the moment, the pedal is convenient to step downwards, the throttle lever is driven to rotate together, when the pedal is treaded downwards violently, due to the fact that the stress is too large, the limiting block can be extrudedinto the rotating block under the action of the limiting groove, the rotating block can rotate conveniently, the effect that the rotating block and the mounting cylinder are relatively fixed conveniently is achieved, the situation that when the pedal is treaded, the throttle lever cannot be driven to rotate is avoided, and when the pedal is suddenly treaded violently, the rotating block rotates,and transmission is convenient.
