Problems solved by technology

[0004] The display screen in the car navigation assistance system is usually installed in the box under the front windshield, and the distance between the display screen and the steering wheel is between 30-55 cm. When the user uses the car navigation system, most of them are driving with both hands. On the steering wheel, if you want to use one hand to touch the display screen, the "one hand" needs to move a distance of 30-55 centimeters to complete the touch operation, and then move a distance of 30-55 centimeters to complete the reset of the hand , such an operation causes inconvenience to the user
What's more, the user needs to perform multiple touch selection operations to press the function key he wants, which will cause the driver to "hold the disk with one hand" for a long time, resulting in certain potential safety hazards

Embodiment Construction

[0030] The present invention will be described in further detail below by means of specific embodiments:

[0031] The vehicle-mounted navigation auxiliary system of this embodiment is used to assist the navigation system to carry out button input. The navigation system includes a vehicle-mounted MCU for information processing, and its steering wheel of the vehicle to which this system is applicable must meet the following conditions: (such as figure 1 As shown) the steering wheel includes a rim 2, a spoke and a support frame, wherein the spoke includes an inherent spoke fixed between the rim and the support frame and an additional radial spoke 1 rotatably connected in the rim; as known to the public, the wheel The ring and the inherent spokes are prior art, and the supporting frame (that is, the support shaft of the steering wheel, the steering wheel will rotate on this rotating shaft) to support the spokes is also the prior art. In other words, the improvement of the existing ...

Abstract

The invention relates to a vehicle navigation auxiliary system, which includes a catalog confirmation subsystem, a key confirmation subsystem and a comprehensive judgment unit. The key catalog is determined through the catalog confirmation subsystem, and the specific key under the corresponding catalog is confirmed through the key confirmation subsystem, and then the The final confirmation information is handed over to the vehicle-mounted MCU for specific operations. This patent can assist the driver to perform key input, and prevent the driver from leaving the steering wheel for a long distance or for a long time.

Description

technical field [0001] The invention relates to a navigation system, in particular to a vehicle navigation auxiliary system. Background technique [0002] Car navigation system is a kind of car electronic system which integrates DVD player and GPS navigation. The best driving route. On the other hand, the audio-visual system also has strong expansibility. For example, it can be combined with the reversing radar to assist safe reversing, and it can be used for car anti-theft when combined with the vehicle tracking system. At present, the installation of the car DVD navigation audio-visual system There are more and more cars. [0003] Along with the increase of user demand, many function keys have been added on the car navigation system, because the space at the display screen is limited, the prior art provides a car navigation system with a touch screen, through the touch screen with page turning function, in limited Provide users with more function buttons in the space; ho...
