The invention discloses an automotive electric power steering control system at least comprising a sensor, a controller and an executor. The sensor is used for sensing automotive signals and transmitting the automotive signals to the controller for processing; the controller controls the executor to perform power steering; the executor comprises an EPS (expandable polystyrene) field-effect transistor relay drive module, a motor drive module, a field-effect transistor relay and an assist motor; the output end of the controller drives the field-effect transistor relay through the EPS field-effect transistor relay drive module; the output end of the controller drives the assist motor through the motor drive module. The existing electromagnetic relay is replaced by the field-effect transistor relay, the defect that the electromagnetic relay is easily burned out is avoided, the service life of the field-effect transistor relay is prolonged, and the system is better in reliability and safety.
