System and method for assisting driver when reversing motor vehicle

A method for assisting a driver to navigate while moving a motor vehicle in reverse, the method utilizing a wireless communication device, the motor vehicle comprising a real-time information acquiring module to collect information of a road at the rear of the motor vehicle, the method comprising:

• detecting movement information of the motor vehicle via the wireless communication device;
• determining whether the motor vehicle is in reverse gear according to the movement information;
• and
• actuating the real-time information acquiring module when the motor vehicle is in reverse gear, and sending the information of the road at the rear of the motor vehicle to the wireless communication device for display by the wireless communication device;
• wherein the wireless communication device comprises an acceleration sensor and a gravity sensor to detect the movement information, the acceleration sensor is configured to detect the acceleration of the motor vehicle, and the gravity sensor is configured to detect if there is a backward movement of the motor vehicle in a predetermined time period after the acceleration of the motor vehicle becomes zero.

A motor vehicle comprising:

• a real-time information acquiring module to collect information of a road at the rear of the motor vehicle
• a wireless communication device configured for wirelessly communicating with the real-time information acquiring module, the wireless communication device comprising:
• an acceleration sensor and a gravity sensor, the acceleration sensor being configured to detect the acceleration of the motor vehicle, the gravity sensor being configured to detect if there is a backward movement of the motor vehicle in a predetermined time period after the acceleration of the motor vehicle becomes zero;
• a control module configured to signal the real-time information acquiring module when there is a backward movement of the motor vehicle in a predetermined time period after the acceleration of the motor vehicle becomes zero, wherein the information of the road at the rear of the motor vehicle collected by the real-time information acquiring module is capable of being wirelessly sent to the wireless communication device;
• and
• a display configured to display the information of the road at the rear of the motor vehicle received from the real-time information acquiring module.
