[0042] According to the first embodiment, the present invention further proposes a second embodiment for further illustration.

[0043] image 3 It is a flow chart of the second embodiment of the navigation method of the present invention. see image 3 , and see with figure 1 The block diagram of the navigation device, as shown in steps S21 and S22, S21: use the input module to input the starting point and the destination to be reached; and S22: use the input module to input the avoidance of special road sections. When the input module inputs the planned avoidance route for a special road section, as described in steps S23 to S25, S23: use the input module to input the special road section to be avoided; S24: read the road condition information and map information through the storage module; and S25 : Use the processing module to plan path information.

[0044] It should be noted that in step S25, the processing module plans route information according to the GPS signal, t...

Abstract

The invention discloses a navigation device having a three-dimensional gravity sensor and a navigation method thereof. The navigation device comprises an input module, a sensing module, a processing module and a storage module, wherein the input module inputs a start point, an destination and a special road section; the sensing module senses three-dimensional accelerated speeds; the processing module calculates road condition information according to the three-dimensional accelerated speeds; and the storage module stores the road condition information and cartographic information. A user can utilize the navigation method having three-dimensional gravity sensor to make the navigation device have the functions of sensing the three-dimensional accelerated speeds, recording road conditions by the storage module, avoiding special road sections and warning and prompting. The navigation device can be used as a racing track detector, directly records and displays gravitational acceleration at corners, or can be used as a comfortable degree detector for an automobile manufacturer, or can be use as a selection reference for comfortable road for a driver.

Description

【Technical field】 [0001] The present invention relates to a navigation device with a three-way gravity sensor and its method, in particular to a navigation device with a three-way gravity sensor capable of sensing three-way acceleration and storing road condition information and its method. 【Background technique】 [0002] At present, most navigation devices have the functions of route planning, route recommendation and road query, but the accuracy of the navigation device is often affected by poor reception of satellite positioning signals. Therefore, a higher-end navigation device will add a gyroscope to assist in positioning, so that the navigation device can continue to navigate and position when it cannot receive satellite positioning signals. [0003] The function of the gyroscope is to detect the movement state of the object, such as acceleration, braking or steering, etc., and the instantaneous relative acceleration and relative direction angle changes due to the law ...
