(1) load sensing proportional valve: the pretightening force of the spring is changed by utilizing the change of the distance between the vehicle body and the axle, and is correspondingly adjusted along with the increase of the load of the vehicle, so that an approximately ideal braking force distribution can be obtained under any load condition. But the valve body can only adjust the brake of the rear shaft, has slow response and low reliability, and is gradually eliminated by the market;

(2) ABS/ESC: in the braking process, the wheel slip rate is controlled within a reasonable range through real-time monitoring of the wheel speed, so that the ground adhesion condition is fully utilized, the scheme is widely and mature in the current market, but the development and application cost is high, and the calibration and adjustment period is long. However, the economy is extremely poor when the technology is applied to the kart.

(3) Pressure regulating/limiting valve: the pressure of the rear axle pipeline is adjusted, so that the braking force distribution condition of the front axle and the rear axle is adjusted, and the front wheel and the rear wheel are locked at the same time. However, the pressure regulating/limiting valve is mostly suitable for light vehicles with a large ratio of the height of the mass center to the wheelbase, and the vehicles are influenced by inertia during braking and have obvious load transfer, so the pressure regulating/limiting valve is not suitable for kart and racing vehicles with low mass center and short wheelbase.
