Description

A car navigation method, device and navigation terminal

technical field

The invention belongs to the field of car navigation, and in particular relates to a car navigation method, device and navigation terminal.

Background technique

Increased car usage is a major cause of traffic congestion. During peak hours, the flow of commuting, traveling, and shopping vehicles pours into the city center from all directions. As the number of vehicles continues to increase, the existing roads cannot bear such a large amount of traffic, resulting in traffic jams.

In order to alleviate the increasing pressure of urban traffic congestion, some large cities have begun to consider charging traffic congestion charges for key congested road sections. For example, Beijing issued the "Green Beijing Development and Construction Plan" during the "Twelfth Five-Year Plan" period, proposing to study and formulate key road sections or areas The purpose of the traffic congestion charging scheme is to reduce the demand for vehicle traffic, change the driving path of vehicles, optimize the distribution of traffic flow in the road network, and change the distribution of residents' travel time.

At present, it is very inconvenient for users to obtain information on the location and charging time of the traffic congestion toll section. It can only be known through the announcement of the government department or the driver's actual encounter. time (especially for non-local drivers), it will increase travel time and traffic costs.

Contents of the invention

Detailed ways

The present invention adds a traffic congestion toll road section in the navigation terminal, reminds the user whether to avoid the traffic congestion toll road section when there is a traffic congestion toll road section on the user's driving path, and helps the user to avoid the traffic congestion toll road section.

Fig. 1 shows the implementation flow of the car navigation method that the embodiment of the present invention provides, and details are as follows:

In step S101, it is judged whether there is a traffic congestion charging road section in the user's driving route according to the stored traffic congestion charging road section information;

In an embodiment of the present invention, if the user sets a destination for car navigation, the process of judging whether there is a traffic congestion charging road section in the user's driving route according to the stored traffic congestion charging road section information specifically includes:

1. According to the destination selected by the user and the stored traffic congestion charging road section information, it is judged whether there is a traffic congestion charging road section in the route to the destination;

2. When it is judged that there is a traffic congestion toll road section in the route to the destination, calculate the time required for the vehicle to reach the traffic congestion toll road section;

3. According to the time required to reach the traffic congestion toll road section, judge whether the vehicle will be charged when it arrives at the traffic congestion toll road section;

4. When the vehicle arrives at the toll section for traffic congestion, output a prompt to the user whether to avoid the toll section for traffic congestion.

As a preferred embodiment of the present invention, when the user chooses to avoid the traffic congestion charging road section when the user sets the destination for car navigation, the driving route avoiding the traffic congestion charging road section is planned and output to the user.

As a preferred embodiment of the present invention, when the user sets the destination for car navigation, when the user chooses not to avoid the traffic congestion toll section, it is judged whether the distance between the current location of the vehicle and the traffic congestion toll section is less than the set distance. Threshold, for example 500 meters.

In an embodiment of the present invention, if the user does not set a destination for car navigation, the process of judging whether there is a traffic congestion charging road section in the user's driving route according to the stored traffic congestion charging road section information specifically includes:

1. Obtain the current location of the vehicle in real time;

2. According to the current location of the vehicle, it is judged whether there is a traffic jam toll section within the set distance.

In step S102, when it is determined that there is a traffic congestion charge road section on the driving route of the user, a prompt of the traffic congestion charge road section is output to the user.

Here, when the distance between the vehicle's current location and the traffic congestion toll section is less than the set threshold or when there is a traffic congestion toll section within the set distance according to the vehicle's current location, a prompt of the traffic congestion toll section is output to the user.

As an embodiment of the present invention, if the user sets the destination for car navigation, when there is a traffic congestion toll section on the user's driving path, the user is reminded to avoid it. The specific implementation process is shown in Figure 2, and is described in detail as follows:

In step S204, it is judged whether there is a traffic jam toll section in the driving route selected by the user, if yes, step S205 is executed, otherwise step S209 is executed;

In step S205, calculate the time required to arrive at this traffic jam toll section;

In step S206, according to the time required for arriving at the traffic congestion toll road section, it is judged whether the user's vehicle is charged when the traffic congestion toll road section arrives, if yes, step S207 is executed, otherwise step S209 is executed;

In step S207, the user is prompted whether to avoid the traffic jam toll section, if the user chooses to avoid, step S208 is performed, otherwise step S2010 is performed;

In step S208, plan and output other driving routes to the user;

In step S209, the guide begins;

In step S2010, provide driving guidance to the user;

In step S2011, it is judged whether the distance between the current location of the vehicle and the traffic jam toll road section is less than a set threshold, such as 500 meters, if yes, step S2012 is executed, otherwise step S2010 is executed;

In step S2012, when the distance between the current location of the vehicle and the traffic congestion charging road section is less than a set threshold, a prompt of the traffic congestion charging road section is output to the user.

As an embodiment of the present invention, if the user does not set a destination, then according to the current location of the user's vehicle, it is judged whether there is a traffic jam toll section in front to remind the user. The specific implementation process is shown in Figure 3 and is described in detail as follows :

In step S301, the current location of the vehicle is obtained in real time according to GPS positioning;

In step S302, according to the current location of the vehicle, it is judged whether there is a traffic jam toll road section within the set distance, if yes, execute step S303, otherwise execute step S301;

In step S303, a prompt of the traffic congestion toll section is output to the user.
