Description

Vehicle warning system

This creation is about a warning system, and in particular, a warning system for a vehicle.

Modern people are paying more and more attention to the safety of automobiles. In recent years, many car manufacturers have successively proposed new technologies such as vehicle safety architecture and collision prevention devices. Therefore, in recent years, many vehicle safety systems have been developed. The safety system of the vehicle includes a passive safety system and an active safety system. Passive safety systems include airbags, body structures, seat belt control mechanisms, and the like. The active safety system includes lane offset warning, reverse assist system, anti-lock braking system, dynamic tracking or active lighting headlights.

Among them, when the user is driving, it may cause the area that the human eye cannot see because of the visibility limit of the angle of the rear view mirror or the shielding of the structure of the vehicle body, that is, some driving visual dead angles. Because these driving visual dead angles often lead to many accidents, which caused the breakdown of many families. Therefore, in order to protect the safety of the driver, and to protect other people other than the driver, the problem of solving the visual dead angle of the driving has become a very important issue.

This creation provides a vehicle warning system that can help to overcome the problem of driving visual dead angles.

The present invention provides a vehicle warning system comprising a plurality of warning lights disposed on a steering wheel of the vehicle. Multiple detection areas are defined around the vehicle, and each A detection area corresponds to one of the warning lights. When an object is detected in one of the detection areas, the corresponding warning light is illuminated. In this way, the driver can clearly know where there is an object around the vehicle and avoid the vehicle hitting the object.

The above and other objects, features and advantages of the present invention will become more apparent and understood.

1 is a schematic diagram of a driving alert range according to an embodiment of the present invention; and FIG. 2 is a schematic diagram showing a configuration of a warning light number according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2 together, the warning system provided in this embodiment includes a plurality of warning lights, such as 202, 204, and 206, which are disposed on the steering wheel 210 of a vehicle 100.

In addition, a plurality of detection areas, such as A1-A8, are divided around the vehicle 100. Each of the detection areas A1-A8 corresponds to at least one of the warning lights on the steering wheel 210. In this embodiment, the warning light disposed on the steering wheel 210 can be implemented by using a light emitting diode element. When an object is found to enter any of the detection areas A1-A8, the corresponding warning light will be illuminated. For example, when an object is detected in the detection area A1 or A2, corresponding warning lights (such as the warning lights 202, 204, and 206) are illuminated. In this way, when the user sees that the warning light is illuminated, it is known in which direction of the vehicle an object appears, and the vehicle 100 is prevented from hitting the object.

3 is a block diagram of a vehicle alert system in accordance with an embodiment of the present invention. Referring to FIG. 3 , the vehicle warning system 300 provided in this embodiment includes a controller 302 , a warning light module 304 , and a detection module 306 . The controller 302 is coupled to the warning light module 304 and the detection module 306. Warning light module 304 includes a plurality of warning lights disposed on the steering wheel 210 described above. In addition, the detection module 306 includes a plurality of detection units D1-D8 disposed around the vehicle 100 to respectively transmit detection signals toward respective preset directions.

In this embodiment, the controller 302 can be connected to the detection module 306 through a transmission interface 310. The transmission interface 310 can be a wired interface, such as a Controller Area Network (CAN) bus or a Local Interconnect Network (LIN) bus. In other embodiments, the transport interface 310 can also be a wireless transmission interface.

In addition, the detecting units D1-D8 can be implemented by using a radar unit. In these embodiments, each of the detecting units D1-D8 can emit a radar wave as a detection signal. In other embodiments, the detecting units D1-D8 may be ultrasonic units, and may emit ultrasonic waves as detection signals. The detection range of each detection unit D1-D8 is the detection area A1-A8.

When one of the detecting units D1-D8 detects the echo of the detection signal reflected by the object, it represents that an object enters one of the detection areas A1-A8. At this time, the detecting unit that detects the echo will output a control signal CS. At this time, the control signal CS can be transmitted to the controller 302 through the transmission interface 310, so that the controller 302 illuminates the corresponding indicator light in the warning light module 304 according to the received control signal CS.

In some embodiments, the controller 302 can also determine the distance between the object in one of the detection areas A1-A8 and the vehicle 100 itself through the detection module 306. When the distance between the vehicle and the object in one of the detection areas A1-A8 is shorter, the controller 302 will make the frequency of the corresponding warning light blink faster. On the other hand, if the distance between the vehicle and the object in one of the detection areas A1-A8 is longer, then control The 302 will slow down the frequency at which the corresponding warning light flashes.

In some embodiments, the controller 302 can also determine the distance between the object in one of the detection areas A1-A8 and the vehicle 100 itself through the detection module 306. When the distance between the vehicle and the object in one of the detection areas A1-A8 is changed from far to far, the controller 302 causes the wavelength of the light wave emitted by the corresponding warning light to be changed from short to long (the color changes from blue to red). ;vice versa.

4 and 5 are respectively schematic diagrams showing the configuration of a warning light according to other embodiments of the present invention. Referring to FIG. 4 and FIG. 5, respectively, in the embodiment disclosed in FIG. 2, the warning light is disposed on the circumferential grip of the steering wheel 210. In FIGS. 4 and 5, the warning light can also be disposed in the central region 402 of the steering wheel 210.

In summary, in the present creation, a plurality of warning lights are arranged corresponding to the detection areas around the vehicle, and when an object is found in the detection area, the corresponding warning light can be illuminated. Therefore, driving can instantly know where the vehicle appears, and reduce the impact of driving dead angles.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application.
