Driving direction prompting system

Abstract

The invention relates to a driving direction prompting system. The driving direction prompting system comprises an information acquisition module and a direction prompting module. The information acquisition module is used to acquire state information from a navigator and direction information synchronized with the state information. The direction prompting module comprises a current turning unit and a transition unit. The trigger condition of the current turning unit is that whether a current vehicle is in a turning state is determined according to the state information. Under the control of the current turning unit, a projection device is used to project an indication cursor on a steering wheel. The trigger condition of the transition unit is that when the current vehicle is not in the turning state according to the state information, the direction information is nothing. By using the transition unit, the indication cursor disappears. In order to overcome the technical defect of the prior art of poor driving experience, the driving direction prompting system used for enabling a driver to avoid strong light in front of the vehicle at the same time of observing the navigation direction in nights is provided.

Description

technical field [0001] The invention belongs to a vehicle driving navigation system, in particular to a driving direction prompting system. Background technique [0002] The navigation function involves receiving location information from multiple satellites through the Global Positioning System (GPS), calculating the current location of the vehicle, displaying the calculated location by mapping it on a map (i.e., map matching), receiving a destination from the user, A route search is performed from a calculated current position to a destination according to a predetermined route search algorithm, the found route is displayed by mapping it on a map, and a user is provided with guidance along the route to the destination. However, most of the existing driving direction prompting systems are realized by voice prompting, which means that it is inconvenient for the driver to listen to music or broadcast during navigation, which will directly affect the driving experience of the ...

However, this technology still has the following technical defects: when driving at night, trucks with headlights often appear in front of the car, and the brightness of the headlights is relatively high. The stronger it is, but the owner of the car must keep his eyes on the front windshield in order to know the navigation direction of the vehicle in real time. This kind of driving experience is extremely poor
