FIELD: transport.
SUBSTANCE: proposed device comprises electrical amplifier 200, first control device, determining device, and second control device. Said electrical amplifier 200 comprises motor 206 to allow applying steering amplification torque to steering wheel shaft 202. Setting voltage, equal to or lower than upper limit voltage, is fed to motor 206. Proposed device defines if motor 206 is in state corresponding to power generation on the basis of motor rpm and fed setting voltage. Drive device 208 is controlled to decrease power output of motor 206 in stage of power generation.
EFFECT: higher safety.
