The invention provides a new energy automobile steering system IGBT protection method, system and equipment, and the method comprises the steps: obtaining the working state of a DC/DC converter and the voltage U of a storage battery when a new energy automobile is started; judging U > = storage battery normal voltage U0; if U is greater than or equal to U0, turning control Ult is started; u0, judging that U is greater than or equal to U1; u > = U1, determining whether the working state of the DC/DC converter is normal; if yes, steering control is started; if not, an alarm signal is output, and shutdown processing is carried out; ult; u1, the new energy automobile cannot be started; wherein U1 is the lowest voltage meeting the requirement of providing the IGBT driving capability. According to the method, when the new energy automobile is started and after steering control is started, corresponding information is obtained through a CAN network, and interval and condition judgment is conducted on the obtained information; and executing a corresponding action according to a judgment result. The problem that a steering control IGBT of a new energy vehicle fails under different working conditions is solved, parts are protected against failure, and driving safety is protected.
