Description

Technical Field

[0001] The utility model relates to the technical field of vehicle equipment, and more particularly to a vehicle and a voice prompt system used for the vehicle. Background Art

[0002] Trucks are increasingly used in modern logistics and transportation bases, construction sites, and other locations. With the increase in urban traffic and the widespread use of heavy vehicles, the risk of traffic accidents is also increasing. Drivers of large vehicles such as trucks often have blind spots, which can lead to accidents when driving, reversing, and turning. This is especially true when large trucks are driving, reversing, parking, or loading and unloading in crowded areas. Therefore, improving truck safety is a critical issue.

[0003] In the prior art, to improve the safety factor of trucks and ensure the safety of nearby pedestrians, trucks are often equipped with sound and light alarms to provide warnings. These alarms typically have both audible and flashing functions, alerting pedestrians and other vehicle drivers to avoid collisions. Current dump trucks are also equipped with sound and light cargo box lift alarms, which can warn pedestrians and other vehicle drivers of their vehicles by emitting sounds and flashing lights while loading or unloading, thereby reducing the probability of accidents.

[0004] However, the existing driving alarms and cargo box lifting alarms are independent of each other, that is, two sets of sound and light alarms must be installed on each vehicle. This not only makes it impossible to effectively coordinate and interact, but also has high hardware costs and a relatively high probability of failure, resulting in higher operating costs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a vehicle and a voice prompt system for the vehicle, which can effectively improve the safety of vehicle driving and cargo box lifting on the basis of reducing hardware costs and operating costs, provide timely and effective warnings to other traffic participants around, and reduce the accident rate.

[0010] Preferably, in the above-mentioned voice prompt system for vehicles, the cargo box lifting state detection device includes a body control module and a cargo box lifting sensor switch installed on the vehicle chassis. When the cargo box is in a non-lifted state, the cargo box lifting sensor switch is in contact with the vehicle chassis. When the cargo box is in a lifted state, the cargo box lifting sensor switch is disengaged from the vehicle chassis. After disengaging from the cargo box, the cargo box lifting sensor switch generates a switch signal indicating that the cargo box is in a lifted state and transmits it to the body control module. The body control module is used to generate a corresponding second message according to the switch signal.

[0011] Preferably, in the above-mentioned voice prompt system for a vehicle, the second communication device includes a second CAN bus connected to the body control module, and the second CAN bus is used to transmit the second message generated by the body control module to the second voice prompt module so that it emits a cargo box lifting warning prompt sound.

[0012] Preferably, in the above-mentioned voice prompt system for vehicles, the cargo box lifting sensor switch is a magnetic switch arranged in the lifting switch circuit, and when the cargo box is in a non-lifted state, the cargo box lifting sensor switch is in contact with the vehicle chassis so that the lifting switch circuit is in a conductive state; when the cargo box is in a lifted state, the cargo box lifting sensor switch is disengaged from the vehicle chassis so that the lifting switch circuit is in an open state, resulting in a level change, and the cargo box lifting sensor switch is used to transmit the information of the level change to the body control module, and the body control module is used to generate the second message according to the information of the level change.

[0020] The core of this utility model is to provide a vehicle and a voice prompt system for the vehicle, which can effectively improve the safety of vehicle driving and cargo box lifting on the basis of reducing hardware costs and operating costs, provide timely and effective warnings to other traffic participants around, and reduce the accident rate.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The present invention provides a method for implementing a voice prompt system for a vehicle. Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of a voice prompt system for a vehicle provided by the utility model. The voice prompt system for a vehicle may include a voice prompter 1. The voice prompter 1 has a first voice prompt module 11 and a second voice prompt module 12. The first voice prompt module 11 is connected to the pedestrian perception component 3 outside the vehicle through the first communication device 2 to emit a pedestrian warning prompt sound when receiving pedestrian information outside the vehicle, and the second voice prompt module 12 is connected to the cargo box lifting state detection device 5 through the second communication device 4 to emit a cargo box lifting warning prompt sound when the cargo box is in the lifting state.

[0023] In this embodiment, the voice prompter 1 can alarm pedestrians outside the vehicle and issue warning sounds to pedestrians, including but not limited to voice or buzzer sounds, and can also issue warning sounds to surrounding traffic participants in response to the lifting status of the cargo box, which also includes but is not limited to voice or buzzer sounds, and has alarm functions in both cases. It can be seen that this embodiment integrates multiple alarm functions into the same device, thereby reducing the complexity of the system, reducing hardware costs, and making maintenance and troubleshooting simpler. In this way, users only need to pay attention to the status of a single voice prompter during maintenance, rather than multiple independent alarm devices, thereby reducing the complexity and cost of maintenance, simplifying the vehicle's electrical wiring, improving the reliability of the overall system, and ensuring good coordination and interaction between each alarm function, thereby improving the response speed and response accuracy of the entire system.

[0024] It can be seen from the above technical solution that in the embodiment of the above-mentioned voice prompt system for vehicles provided by the present invention, since it includes a voice prompter, the voice prompter has a first voice prompt module and a second voice prompt module. The first voice prompt module is connected to the pedestrian sensing component outside the vehicle through the first communication device to issue a pedestrian warning prompt sound when receiving pedestrian information outside the vehicle, and the second voice prompt module is connected to the cargo box lifting state detection device through the second communication device to issue a cargo box lifting warning prompt sound when the cargo box is in the lifting state. It can be seen that this solution only requires one voice prompter to simultaneously realize the pedestrian warning prompt sound outside the vehicle and the cargo box lifting warning prompt sound, thereby effectively improving the safety of vehicle driving and cargo box lifting on the basis of reducing hardware costs and operating costs, and providing timely and effective warnings to other traffic participants around, thereby reducing the accident rate.

[0025] In a specific embodiment of the above-mentioned voice prompt system for a vehicle, reference is made to Figure 2 , Figure 2This is a schematic diagram of a specific embodiment of a voice prompt system for a vehicle. The aforementioned pedestrian sensing component 3 may include an image acquisition component 31 and an image analysis component 32. The image analysis component 32 is communicatively connected to both the image acquisition component 31 and the first communication device 2. The image analysis component 32 is configured to generate a first message when determining the presence of a pedestrian outside the vehicle based on images captured by the image acquisition component 31, and transmit the first message to the first communication device 2. Furthermore, the first communication device 2 may include a first CAN bus, which is configured to transmit the first message to the first voice prompt module 11, causing the first voice prompt module 11 to emit a pedestrian warning tone. It should be noted that the CAN bus is a high-speed communication protocol for vehicle electronic systems that supports real-time, reliable data exchange. It is primarily used for communication between in-vehicle controllers and sensors. The information exchanged is typically referred to as a message, which can be parsed to extract data. This embodiment is designed for situations where the voice prompter and the pedestrian sensing component are on the same network. In this case, communication can be achieved without a gateway for message relay, resulting in higher communication efficiency.

[0026] In another specific embodiment of the above-mentioned voice prompt system for a vehicle, the above-mentioned first communication device 2 also includes a gateway connected to the first CAN bus, and the gateway is connected to the image analysis component 32. This gateway is used to forward the first message to the first voice prompt module 11 through the first CAN bus so that the first voice prompt module 11 emits a pedestrian warning prompt sound.

[0027] In this case, the image acquisition component 31 can be a blind spot camera, and the image analysis component 32 can be a driving recorder. This driving recorder can record vehicle driving related information, including speed, driving time, location, sudden braking and other data. High-performance blind spot cameras can be arranged on the outside of the vehicle to improve driving safety and enhance perception of the surrounding environment. These cameras can monitor and record the environment around the vehicle in real time, including road conditions, traffic signs and potential traffic participants. The driving recorder can use advanced image processing algorithms and machine learning technology to analyze the image stream from the camera in real time to confirm whether there are pedestrians in the picture. Once the driving recorder detects a pedestrian, it will generate a specific signal or message, including a unique flag bit, to trigger a subsequent alarm mechanism. This message can use a standardized information format: a data frame of the CAN (Control Area Network) protocol to facilitate transmission in the vehicle's internal network. Specifically, this blind spot camera can be connected to a driving recorder via a video transmission line. The driving recorder analyzes the images transmitted by the blind spot camera in real time. The driving recorder is connected to the gateway via the first CAN bus. When the driving recorder recognizes that there are pedestrians around the vehicle body, it will send a corresponding message status value. The message is transmitted via the first CAN bus. When the gateway receives the message sent by the driving recorder, it can transmit the message to the network where the voice prompter is located via the CAN bus. After receiving the corresponding message status value, the voice prompter can issue a pedestrian warning prompt. Specifically, as the message arrives, the voice prompter immediately recognizes the specific flag bit and activates the predefined warning through the built-in audio playback module, issuing a voice prompt of "Danger large vehicle, please stay away", quickly alerting the driver and surrounding pedestrians, ensuring that all relevant parties can respond in time to avoid potential accident risks, thereby ensuring better road traffic safety. It can be seen that the gateway can manage and coordinate the mutual conversion of multiple communication protocols and data types here to ensure that data information is effectively transmitted between different systems of the vehicle (such as the power system, safety system, in-vehicle entertainment system, etc.).

[0028] In another specific embodiment of the above-mentioned voice prompt system for a vehicle, continue to refer to Figure 2The cargo box lift state detection device 5 may include a body control module 51 and a cargo box lift sensor switch 52 mounted on the vehicle chassis. When the cargo box is not lifted, the cargo box lift sensor switch 52 is in contact with the vehicle chassis. When the cargo box is lifted, the cargo box lift sensor switch 52 is disengaged from the vehicle chassis. After disengaging from the cargo box, the cargo box lift sensor switch 52 generates a switch signal indicating that the cargo box is lifted and transmits it to the body control module 51. The body control module 51 is configured to generate a corresponding second message based on the switch signal. As can be seen, utilizing this cargo box lift sensor switch 52 can accurately detect the cargo box lift condition, thereby ensuring timely and accurate issuance of an alarm signal for effective alarming. Other implementation methods may also be selected based on actual needs and are not limited herein. Furthermore, the second communication device may include a second CAN bus connected to the body control module 51. The second CAN bus is configured to transmit the second message generated by the body control module 51 to the second voice prompt module 12, causing it to issue a cargo box lift warning tone. Furthermore, in a specific implementation, the cargo box lifting sensor switch 52 can be a magnetic switch arranged in the lifting switch circuit. When the cargo box is in a non-lifted state, the cargo box lifting sensor switch 52 contacts the vehicle chassis to put the lifting switch circuit in a conductive state. When the cargo box is in a lifted state, the cargo box lifting sensor switch 52 is disengaged from the vehicle chassis to put the lifting switch circuit in an open state, resulting in a level change. The cargo box lifting sensor switch 52 is used to transmit the level change information to the body control module 51, and the body control module 51 is used to generate a second message based on the level change information.

[0029] Specifically, this implementation method is to install a lifting switch based on the magnetic attraction principle at the connection between the cargo box and the chassis of the vehicle. When the cargo box is lifted, the attraction is disconnected and the circuit of the lifting switch is opened. The body control module monitors the level signal status of the lifting switch through a hard line. When the lift switch circuit is open, the level signal changes. When the body control module detects the level signal change, it sends a corresponding message to the voice prompt through the CAN bus. The voice prompt can then issue a warning tone or a buzzer. At this time, if there are pedestrians or vehicles around, when they hear this warning tone, they can stay away from the vehicle to avoid damage caused by falling objects, thereby reducing the risk of accidents.

[0030] In a preferred embodiment of the above-mentioned voice prompt system for a vehicle, the body control module 51 can also be communicatively connected to the lighting module to generate a third message based on a signal that the light is on and send the third message to the second voice prompt module 12. This second voice prompt module 12 is used to reduce the cargo box lifting warning tone to a volume corresponding to the night mode when receiving the third message.

[0031] In specific implementation, when the driver turns on the position lights or low beam lights in dim light at night, the state change of the light switch will be transmitted to the body control module, which will correspondingly send a low beam light status signal message. The voice prompter receives the low beam light status message sent by the body control module. After recognizing that the low beam light status message value is on, the voice prompter enters night mode, and the volume of the voice sound module can be reduced through the chip control. It can be seen that this can be adjusted according to different working environments and needs. When the vehicle is working in a quiet environment at night, the sound can enter night mode and reduce the volume to avoid noise pollution and disturbing people, making the whole solution more humane.

[0032] In view of the fact that the sound and light alarms installed on existing trucks often face some problems during use, especially in high water pressure washing environments, the sound and light alarms often malfunction, resulting in their functional failure, which becomes a safety hazard. Moreover, the working environment of cargo trucks is generally harsh, and exposed electrical components are often damaged. Humid or cold weather conditions may cause oxidation of the internal circuits of the sound and light alarms and the cargo box lifting alarms, affecting their normal operation. Long-term exposure to bad weather will reduce the service life of the alarms. When transporting or loading and unloading goods, the sound and light alarms and the cargo box lifting alarms may also be subjected to physical impact or collision. The damaged alarms may not be able to sound the alarm correctly, which is a safety hazard. Therefore, in another preferred embodiment of the above-mentioned voice prompt system for vehicles, the voice prompter is preferably installed on the front fender on the inside of the vehicle body. It can be seen that this installation position can be blocked by the vehicle body, which can effectively prevent external weather environment factors from having an adverse effect on the voice prompter. The shell can be made of materials such as PC+GF15 to achieve better waterproof and dustproof effects, and the overall structure is more robust. Moreover, the surface of the voice prompter can be further provided with a sealed circular cover, and a sealing ring is provided between the upper cover and the lower cover. The sealing structure prevents water and dust from entering, thereby better avoiding the deterioration of the sound effect.

[0033] It should also be noted that the above-mentioned voice prompter still has basic voice prompt functions, such as turning voice prompts, reversing voice prompts, low-speed voice prompts, etc., which will not be repeated here.

[0034] In one embodiment of a vehicle provided by the present invention, the vehicle includes a vehicle body equipped with a vehicle voice prompt system as described in any of the above. The inclusion of the above-described vehicle voice prompt system effectively improves vehicle driving and cargo box lifting safety while reducing hardware and operating costs, provides timely and effective warnings to other traffic participants, and reduces the risk of accidents.

[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
