[0022] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0023] In order to solve the above problems, the first embodiment of the utility model provides a warning device, which can effectively improve the warning effect on pedestrians when the vehicle is turning, thereby avoiding safety problems for pedestrians in the blind spot of the turning field of vision and improving the safety of vehicle driving.

[0024] In an embodiment, the warning device is used in a vehicle to warn of a blind spot in the vehicle's field of vision when the vehicle turns. The vehicle may be a heavy-duty commercial vehicle or other large vehicle, and there is no limitation to this.

[0025] Reference below Figure 1 A warning device 10 according to an embodiment of the utility model is described. The device includes: a spotlight 1, a rotation angle sensor 2 and a controller 3.

[0026] Among them, the spotlight 1 is used to project a warning image to the ground in the blind spot of the vehicle's field of vision; the angle sensor 2 is used to obtain the steering information of the vehicle; the controller 3 is connected to the spotlight 1, and the controller 3 is used to control the spotlight 1 to project an image when the steering information indicates that the vehicle is in a steering state. Among them, the warning image is an image used to remind pedestrians that the vehicle has a turning action. The warning image is a striking pattern, text or symbol, etc. The warning image can be a red triangle exclamation mark or a yellow triangle exclamation mark. The warning image can be set to a dynamic effect, such as setting the warning image to flash, fade, etc. The warning image can be customized. There is no specific restriction on the number of spotlights 1 in the warning device.

[0027] Specifically, in order to solve this problem, when the warning device in the present application detects that the vehicle is turning, it controls the spotlight 1 to project a warning image onto the ground in the blind spot of the vehicle's field of vision, so as to remind pedestrians of the turning action of the vehicle through visual dynamics. That is, the turning angle sensor 2 collects the turning information of the vehicle, wherein the turning information can be understood as the information generated when the vehicle is turning, and the turning information at least includes the turning angle and the turning direction, etc. The controller 3 obtains the turning information of the vehicle, and when the turning information indicates that the vehicle is in a turning state, for example, the vehicle is in a right turning state or a left turning state, it controls the spotlight 1 to project a warning image onto the ground in the blind spot of the vehicle's field of vision corresponding to the turning state, so as to remind pedestrians to pay attention to the turning action of the vehicle by projecting the warning image through the spotlight 1. Therefore, compared with the method of warning pedestrians by flashing turn signals and turning sound alarm devices when the vehicle turns in the prior art, the warning device in the present application controls the spotlight 1 to project a warning image in the blind spot of the vehicle's turning field of vision when the vehicle turns, which can effectively improve the warning effect on pedestrians when the vehicle turns, thereby avoiding safety problems for pedestrians in the blind spot of the vehicle's turning field of vision, and improving the safety of vehicle driving.

[0028] In the embodiment, the controller 3 controls the warning degree of the warning image projected by the spotlight according to the steering angle of the vehicle. For example, when the steering angle is greater than a preset threshold value, the steering angle of the vehicle is relatively large, and the spotlight 1 is controlled to project a more obvious warning image to the blind spot of the vehicle's field of vision, and the warning image is a red triangle exclamation mark; when the steering angle is less than the preset threshold value, the steering angle of the vehicle is relatively small, and the spotlight 1 is controlled to project a more obvious warning image to the blind spot of the vehicle's field of vision, and the warning image is a yellow image. Therefore, the warning device in the present application dynamically adjusts the warning effect of the warning image as the vehicle turns, so as to strengthen the degree of attention paid by pedestrians to the vehicle's turning, thereby avoiding safety problems for pedestrians in the blind spot of the vehicle's turning field of vision and improving the safety of vehicle driving.

[0029] According to the warning device of the present invention, when it is detected through turning information that the vehicle is in a turning state, the controller 3 controls the spotlight 1 to project a warning image in the blind spot of the vehicle's field of vision. Therefore, compared with the method in the prior art of warning pedestrians by flashing turn signals and turning sound alarm devices when the vehicle turns, the warning device in the present application controls the spotlight 1 to project a warning image in the blind spot of the vehicle's field of vision when the vehicle turns, which can effectively improve the warning effect on pedestrians when the vehicle turns, thereby avoiding safety problems for pedestrians in the blind spot of the vehicle's turning field of vision and improving the safety of vehicle driving.

[0030] In some embodiments, Figure 1 The controller 3 is integrated with the spotlight 1, that is, the controller 3 is integrated with the spotlight 1 to reduce the complexity of installation, and the warning device is more compact and beautiful. For example, the controller 3 is directly built into the spotlight 1, and the controller 3 can be a right-turn spotlight controller 3 or a left-turn spotlight controller 3. The right-turn spotlight controller 3 is an electronic control unit with a CAN (Controller Area Network) bus interface, and can program warning images, and project the warning images through the spotlight 1 into the right-turn visual blind spot to warn pedestrians.

[0031] In the embodiment, the warning device controls the spotlight 1 to dynamically project a warning image in the blind spot when turning, and reminds pedestrians by flashing the turn signal and the turning sound alarm device, so as to increase the warning of the blind spot area and ensure the safety of pedestrians.

[0032] The second aspect of the present invention provides a vehicle 100, such as Figure 1 As shown, the vehicle 100 includes the warning device 10 of the above embodiment.

The LIN line is a low-cost serial communication network defined for automotive distributed electronic systems. The LIN line has the advantages of low cost, low power consumption, high reliability, easy scalability and ease of use. Specifically, the turning angle sensor 2 of the warning device obtains the steering information of the vehicle and sends it to the electronic stability controller 4 via the LIN line, thereby realizing the transmission of the steering information.

[0040] In some embodiments, Figure 1 As shown, the electronic stability controller 4 and the gateway 5 are connected via a power CAN bus.
