Problems solved by technology
However, in the prior art, when using the GPS function on the mobile device to perform road steering prompts, generally only prompts such as turning left, turning right, going straight, and turning around are generally prompted. Taking left turn as an example, when the left side of the mobile device When there are two, three or more roads, prompting to turn left at this time will bring some confusion to the user, and similar problems will occur in other situations, which will bring some inconvenience to people's travel

specific Embodiment
[0048] see again figure 2 Shown, utilize the above-mentioned two-way heuristic algorithm to continue the specific embodiment of path planning as follows:
[0049] It takes 10 seconds to calculate theoretically from point A to point B, 10 seconds to calculate theoretically from point B to point C, and 15 seconds to calculate theoretically from point A to point C, then carry out path planning from point A to point C AC will be selected as the optimal path, so that it can accurately reflect the actual state of the road, so as to perform correct navigation.
[0050] In practical applications, a panel that is the same as the clock is displayed in the GPS navigation software of the mobile device. When it is necessary to prompt to turn left, the actual direction of the turn will be displayed, and the voice prompts turn left, turn right, go straight, and turn around. hint. When there are more than two roads on the left side of the mobile device, the voice prompt will be revised to:...

The invention relates to an automatic road steering prompting method in mobile equipment equipped with GPS module. The method includes starting the GPS module and opening the GPS port, route projection from origination to terminal, gaining the current position information and scanning in road data base, obtaining the names and characteristic values of current road and the next road, calculating the steering angle of the two roads to obtain the steering angle information, displaying the clock dial centered with crosspoint of the two roads and the corresponding steering angle information in form of needle in screen. The automatic road steering prompting methods in mobile equipment equipped with GPS module can steering prompt automatically and reflect the actual steering conditions at maximum degree; it is benefit for people to determine the steering; implementation procedure is simple, service behaviour is stable, application is extensive, it is convenient to people' s travel in daily life and work.
Description
technical field [0001] The invention relates to the field of mobile equipment, in particular to the field of mobile equipment equipped with a GPS module, and specifically refers to a method for automatically performing road steering prompts on a mobile equipment equipped with a GPS module. Background technique [0002] In modern life, more and more mobile devices are used, and their functions are gradually enriched and improved, and the more popular function is the GPS navigation and positioning function. However, in the prior art, when using the GPS function on the mobile device to perform road steering prompts, generally only prompts such as turning left, turning right, going straight, and turning around, taking left turning as an example, when the left side of the mobile device When there are two, three or more roads, prompting to turn left at this time will bring some confusion to the user, and similar problems will occur in other situations, which will bring some inconv...
