Vehicle and vehicle step apparatus

1. A vehicle, comprising:

a body;

a plurality of doors; and

a vehicle step apparatus including:

an extending and retracting device mounted on the body,

a motor configured to drive the extending and retracting device to extend or to retract,

a detector configured to detect an opening-closing state of each of the doors and to generate a signal indicating the opening-closing state of each of the doors,

a plurality of emitters coupled with the detector and configured to emit the signals, and corresponding to the plurality of the doors respectively,

a receiver configured to receive the signals from the emitters via wireless communication,

a controller coupled with the motor and the receiver and configured to control the motor to drive the extending and retracting device according to the signals, the receiver and the controller being integral with each other so that the wireless signal transmitting from multiple points to one point is realized;

a power source module coupled with the detector and the emitters, and configured to supply power to the detector and the emitters, and

a step member connected with the extending and retracting device,

wherein the vehicle further comprises a storage battery coupled with the receiver and the controller and configured to supply power to the receiver and the controller and

a display coupled with the controller and configured to display, under a control of the controller, the opening-closing state of each of the doors and an extending-retracting state of the extending and retracting device.

2. The vehicle as set forth in claim 1 , wherein the detector includes at least one of a micro-switch and/or an optical coupler.

3. The vehicle as set forth in claim 1 , wherein the emitters are disposed adjacent to the doors respectively and the receiver and the controller are disposed in an engine compartment.

4. A step apparatus for a vehicle having a plurality of doors, comprising:

an extending and retracting device;

a motor configured to drive the extending and retracting device to extend or to retract;

a detector configured to detect an opening-closing state of each of the doors of the vehicle and to generate a signal indicating the opening-closing state of each of the doors;

a plurality of emitters coupled with the detector and configured to emit the signals, and corresponding to the plurality of the doors respectively;

a receiver configured to receive the signal from the emitter via wireless communication;

a controller coupled with the motor and the receiver and configured to control the motor to drive the extending and retracting device according to the signal, the receiver and the controller being integral with each other so that the wireless signal transmitting from multiple points to one point is realized;

a power source module coupled with the detector and the emitters, and configured to supply power to the detector and the emitters, and

a step member connected with the extending and retracting device,

wherein the vehicle further comprises a storage battery coupled with the receiver and the controller and configured to supply power to the receiver and the controller and

a display coupled with the controller and configured to display, under a control of the controller, the opening-closing state of each of the doors and an extending-retracting state of the extending and retracting device.

5. The vehicle step apparatus as set forth in claim 4 , wherein the detector includes at least one of a micro-switch and/or an optical coupler.

6. The vehicle step apparatus as set forth in claim 4 , wherein the controller controls the motor via wire communication.
