Vehicle-mounted navigation system, support used on same and control method of same

Abstract

The invention relates to a vehicle-mounted navigation system and a control method of the system. A vehicle-mounted navigator comprises an external portable navigator, a support and a whole vehicle entertainment system, wherein the portable navigator can be detachably fixed on the support, and the support is directly and fixedly integrated on a center control platform in a vehicle, so that the portable navigator can transmit data with the whole vehicle entertainment system by the support; and the control method includes the steps of entering a navigation mode, outputting sound and video, sending out an command, receiving the command and quitting from the navigation mode. The vehicle-mounted navigation system reduces the allocation threshold, increases the selection range of users to the portable navigator, and accelerates the popularization of the application of the vehicle-mounted navigation system.

Description

【Technical field】 [0001] The invention relates to a vehicle navigation system and a control method thereof, in particular to a vehicle navigation system integrating a vehicle entertainment system and a portable navigator (PND) and a control method thereof. 【Background technique】 [0002] Due to the popularity of vehicles in our country and the continuous advancement of the urbanization process, more and more vehicle drivers rely on vehicle navigation systems to provide them with accurate driving routes when driving out. Therefore, the car navigation system has increasingly become one of the hot spots in the development of my country's automotive electronics market, and many domestic companies have also invested in the production and research and development of car navigation system products. Based on the status quo at home and abroad, the current car navigation system is mainly divided into three categories according to the installation method: front-mounted, semi-front-moun...

Problems solved by technology

Of course, the disadvantages of this rear-mounted system are also prominent: poor security - the bracket of the PND is usually fixed on the front windshield, blocking the driver's sight; too conspicuous, easy to cause theft; far away from the driver, inconvenient to operate; display effect Poor - PND screens generally have a higher configuration of 4.3 inches. Compared with the front-mounted 6.5-inch screens, the display screen is relatively small, and it is usually placed far away from the driver, so it is often difficult to see the navigation when driving Or the specific content of the map; the low integration of the vehicle-PND uses its own built-in speaker to make sound, the sound effect is poor, and there is no audio arbitration with the vehicle audio system, it is easy to cause mutual interference, so that customers cannot hear the prompt: In addition, through The matching power cord takes power from the cigarette lighter port, and the wiring harness is exposed and unsightly
