The invention discloses a steering controller dual-redundancy circuit, a steering controller dual-redundancy system and a vehicle. A main path control circuit and an auxiliary path control circuit of the steering controller dual-redundancy circuit at least comprise a filtering anti-reverse circuit, a step-down circuit, a power management integrated circuit and an external sensor signal filtering circuit. Wherein the filtering anti-reverse circuit is used for filtering an input power supply and preventing reverse current; the step-down circuit is used for reducing the power supply output by the filtering anti-reverse circuit from the first voltage to the second voltage; the power supply management circuit is used for converting the power supply of the second voltage into the power supply of the micro-control chip unit and the external sensor; the external sensor comprises a torque and steering angle sensor or a steering angle sensor; and the external sensor signal filter circuit is used for filtering the input signal of the external sensor. By adopting the circuit, the HWA module and the RWA module can share the same set of circuit architecture, an input power supply with higher voltage is supported, the high-power requirement of the RWA can be met, and the target requirements of light weight and miniaturization can be met.
