A vehicle step apparatus, comprising: a first extending and retracting device comprising a first mounting bracket, a first step bracket, and a first arm assembly coupled between the first mounting bracket and the first step bracket and configured to drive the first step bracket to move between a first extending position and a first retracting position; a second extending and retracting device comprising a second mounting bracket, a second step bracket, and a second arm assembly coupled between the second mounting bracket and the second step bracket and configured to drive the second step bracket to move between a second extending position and a second retracting position; a step mounted on the first step bracket and the second step bracket; a first permanent magnet direct current motor mounted on the first mounting bracket and coupled with the first arm assembly to drive the first arm assembly; and a second permanent magnet direct current motor mounted on the second mounting bracket and coupled with the second arm assembly to drive the second arm assembly; characterized in that the vehicle step apparatus further comprises: a first elastic member configured to elastically deform so as to store energy when the first permanent magnet direct current motor drives the first step bracket to move towards the first extending position, and to release energy so as to assist the first permanent magnet direct current motor to drive the first extending and retracting device when the first permanent magnet direct current motor drives the first step bracket to move towards the first retracting position; and a second elastic member configured to elastically deform so as to store energy when the second permanent magnet direct current motor drives the second step bracket to move towards the second extending position, and to release energy so as to assist the second permanent magnet direct current motor to drive the second extending and retracting device when the second permanent magnet direct current motor drives the second step bracket to move towards the second retracting position. a first extending and retracting device comprising a first mounting bracket, a first step bracket, and a first arm assembly coupled between the first mounting bracket and the first step bracket and configured to drive the first step bracket to move between a first extending position and a first retracting position;
