Abstract: A vehicle power management system and an operating method thereof are provided. The vehicle power management system is adapted for a vehicle load device and a vehicle power supply, and includes a control circuit, a charge/discharge circuit and a backup battery. The control circuit is electrically connected to the vehicle power supply and the vehicle load device, and monitors an output voltage of the vehicle power supply and determines according to the output voltage whether a vehicle engine is started. The charge/discharge circuit is electrically connected to the control circuit and the backup battery. When the vehicle engine is started, the charge/discharge circuit supplies power of the vehicle power supply to the backup battery and the vehicle load device. When the vehicle engine is not started, the backup battery discharges the charge/discharge circuit and the charge/discharge circuit supplies power of the backup battery to the vehicle load device.

Abstract: A vehicle camera device is applied in a vehicle. The vehicle camera device performs image recognition of current driving image to obtain a license-plate pattern in the driving image, and when size of the license-plate pattern is less than a threshold, increases a focus according to current speed of the vehicle.

Abstract: An object detection method and system for multi-points touch are disclosed. The method and system can be used in object processing and identification in the touch display device. The object detection system includes a touch display unit and an object. At least one division area is set in the touch display unit. The object has multiple contact objects. The object detection method includes receiving the first detection signal generated by the multiple contact objects being pressed in the first division area, determining the first shape form by the contact objects, and looking up the object mapping table according to the first shape so as to obtain the corresponding object. When the object operates on the touch display device, the corresponding operation can be displayed on the touch display device based on the object found in the object mapping table.
