The hardware safety protection circuit for the steer-by-wire system provided by this utility model includes a power supply chip, a microcontroller unit, a dual transistor conversion circuit, and a dual MOSFET switching circuit. The dual transistor conversion circuit is connected to the power supply chip via a first line and to the microcontroller unit via a second line. The output of the dual transistor conversion circuit is connected to the input of the dual MOSFET switching circuit, and the output of the dual MOSFET switching circuit is connected to the input of the controlled circuit. When the power supply chip and / or the microcontroller unit detect a hardware abnormality, they each send an independent disconnect signal to the dual transistor conversion circuit. The dual transistor conversion circuit receives these signals and converts them into a unified control signal, which is then sent to the dual MOSFET switching circuit. This causes the dual MOSFET switching circuit to disconnect the controlled circuit and stop its operation, thus achieving multiple layers of hardware protection.
