When the recognized navigation voice contains that the vehicle is about to enter the ramp, an instruction to start the linkage of the ambient light is sent to the interior light controller.

When the recognized navigation voice includes that the vehicle has entered the correct ramp, an instruction to end the linkage of the ambient light is sent to the interior light controller.

When the recognized navigation voice contains the correct steering signal of the road ahead, the interior light controller sends a linkage command for the ambient light to indicate that the road ahead is to the left or right.

When the recognized navigation voice prompts that you need to go straight, the car ambient light will not perform linkage instructions.

The linked car ambient lights include the front row ambient lights in the car and/or the ambient lights on the A-pillars on both sides.

The partitioning of the vehicle ambient light specifically includes a left partition and a right partition, and each partition corresponds to an instruction command issued by the interior light controller.

In the scene where the navigation enters the ramp, the interactive effect requirements of the ambient light include:

Does not affect the environment of the driver in the car;

It does not affect the driver's observation of the situation outside the A-pillar.

A navigation system based on a vehicle-mounted ambient light and voice linkage navigation method, the system includes a vehicle-mounted infotainment host with a voice recognition module, an interior light controller, a vehicle-mounted ambient light, and a vehicle-mounted navigation.

1. The navigation method is more enriched, providing users with various navigation methods and improving the car experience;

2. The atmosphere lights within the driver's visual range are displayed in different areas to reduce the occurrence of going the wrong way;

3. The guidance of the front row ambient lights, enhance the sense of technology in the car, and enhance the sense of car experience;

Fourth, there is no need to add additional accessories for the ambient light in the front area, which saves vehicle costs while realizing lane guidance.

Description of drawings

Fig. 1 is the schematic diagram of the method of the present invention.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example

The present invention mainly provides a navigation method and system based on vehicle ambient light and voice linkage, by combining navigation information, vehicle interior ambient light and the like. When the driver turns on the voice navigation, when faced with the road choice, the ambient light within the driver's visual range can participate in the navigation, providing the driver with auditory guidance while increasing visual sensory guidance to reduce the occurrence of wrong roads .

As shown in Figure 1, the concrete working steps of the present invention are described as follows:

1) Turn on voice broadcast for car navigation;

2) The vehicle infotainment host recognizes the voice information broadcast by the vehicle navigation;

3) Judging whether the turning direction of the current path is a left turn or a right turn according to the voice information;

4) According to the turning direction, the interior light controller controls the corresponding car ambient light (within the driver's visual range) linkage to indicate the specific turning direction.

The identification of key information of the navigation system is specifically:

In the present invention, the navigation system needs to transmit the following three data to the interior light controller:

1. The information that the vehicle is about to enter the ramp (inform the interior light system that the light linkage starts);

2. The vehicle has entered the correct ramp (informing the interior lighting system that the light linkage is over);

3. Correct indication signal of the road ahead (the road ahead is left/right);

In order to adapt to the ramp use scene, it can also be used in the lane change scene. The ambient light in the car is set to only give reminders when the driver is driving safely. In different emergency situations, the interior lights are Do not set related interaction effects to avoid hindering driving safety.

The working principle of the present invention is as follows:

1. The navigation system includes a vehicle infotainment host with a voice recognition module, an interior light controller, a vehicle ambient light and a vehicle navigation;

2. Logical judgment of the navigation system

A) When the navigation system judges that the vehicle is about to enter the road according to the vehicle location, the vehicle navigation will perform voice broadcast, and the vehicle infotainment host will extract keywords through the voice recognition module. For example, when the vehicle announces that the vehicle is about to enter the left road, it will Information is extracted, key information: left.

B) Judgment of complex road conditions. When the information obtained by the car navigation is inaccurate, the navigation system will obtain the current direction of the front of the car, compare the direction of the front of the car with the road that is about to enter, and if it is to the left, it will send a signal to the left The interior light controller, even to the right, does not link with the ambient light when facing the ramp and needs to go straight.

C) The trigger event for the navigation system to send the start command is: according to the positioning information, the vehicle needs to be about to enter the road, and the car navigation broadcasts that the front is about to enter the ramp. The trigger event for the navigation system to send the end command is: according to the positioning information, the vehicle has driven out of the indication the way.

3. Partition interaction of internal ambient lights

A) Regarding the partitioning of the interior lights in the front row, the ambient lights on the A-pillars on both sides are the main basis for partitioning, and without affecting the main atmosphere mode in the car, the ambient lights within the driver's visual range are added, for example The inner longitudinal and bottom transverse joints of the A-pillars on the left and right sides.

B) After receiving the instruction from the navigation module, the interior light controller sends a linkage instruction to the ambient lights in the left/right partition according to the keyword judgment.

4. Choice of ambient light effect

In special scenarios such as navigation into the ramp, the selection of the interactive effect of the ambient light needs to consider the following factors: it does not affect the driver's environment in the car, and does not affect the driver's observation of the situation outside the A-pillar.
