The present invention relates generally to an intelligent vehicle blind spot detention system, and particularly to the warning notice derived from the vehicle blind spot detection system is filtered via an eyesight detection system.
Essentially, there are two kinds of startup mechanism of the blind spot detention system on the market. The first type requires the driver to manually activate such a system by switching the direction light pole. Notably, when the driver ignores or forgets to operate the direction light pole, such a detection system will not work, thus resulting in a potentially dangerous situation for the driver. The second type requires the system automatically and continuously operates even if the driver drives straight without intentions to make the lane change or the right/left turn. Notably, the warning notice provided by the alarming beep under such a situation is unwelcome.
Hence, an intelligent blind spot detention which only alerts the driver when the driver intends to make the lane change or the direction change, is desired.
The invention related to an intelligent vehicle blind spot detection system, includes an MCU (microcontroller unit), visual detectors, a blind spot detection device and a warning device. The MCU can connect with the driving computer through the CAN BUS (Controller Area Network) to receive the real time traffic information, including the navigation, speed, steering wheel, the throttle and brake actuation, ON/OFF status of the lights, and the ADAS (Advanced Driver-Assistance System) related systems, etc. The visual detectors are used to monitor whether the driver's eyesight directs to the left or right rearview mirror, and can be set on either side A-pillar or on the central control panel. The blind spot detection device is used to detect whether there are other vehicles in the blind region of the driver's sight through the corresponding rearview mirror. The blind spot detection device can use the radar wave, camera head or infrared technology to detect the objects. The blind spot detection device can be set on the rearview mirror or appropriate positions of the car body. The light warning of the warning device can be set on the A-pillar or the rearview mirror within the car, as well as the warning sound to remind the driver of other vehicles in the blind area before the driver rotates the steering wheel.
Other advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Referring to
Practically, the visual detectors mainly check the movement of the eye balls of the driver to check whether the eyesight is directed toward the rearview mirrors on two sides of the car. The warning notice only occurs when both the driver looks at the rearview mirror(s) and other vehicles exist in the blind zone. In the invention, the blind spot detectors could be activated only after the visual detector verifies the driver's intention; alternately, the blind spot detectors constantly work while the warning notice is only issued when both the two factors, i.e., the driver's intention to change lane or make a turn and existence of other vehicles in the blind spot zone, are satisfied.
The control system may collect driving information, including operations of the navigation, the speed, the steering wheel, the gas and the brake, and the ON/OFF status of the light, the ADAS, and the related system. The front panel may show such information. The blind spot detection system may be connected to a mobile device or a center controller for activation or deactivation. Through the detailed driving information, the factors verified by the blind spot detection system may determine ending of the changing lane if the direction light pole is back to the neutral position and the brake value is zero. If the car is equipped with the lane deviation detection system, a data from that system may be used as a reference to precisely determine ending of changing lane. If confirmed, the blind spot detection system may change from the warning status to the visual detection status. In other words, if the referencing driving data from other systems can not meet the required values of a stable straight driving manner, the warning signals may continue. An annunciator may be connected to the MCU for reflecting the status. Other operation variations may include showing the warning symbol quietly on the front panel or on the rearview mirror as long as the blind spot detectors verify other vehicles are located at the blind zone of the corresponding rearview mirror, disregarding whether the driver take a look at the rearview mirror, while the warning sound occurs only in response to a positive verification resulting from the set of the visual detectors,
In conclusion, the blind spot detectors are activated only after the visual detectors verifies the driver's intentions to change lane or make a right/left turn, and the warning signal is issued only after other cars or foreign items are verified by the blind spot detectors successively. Alternately, the blind spot detectors are constantly operated while the warning notice is issued only when both the two factors regarding the visual detectors confirms the driver's intention to change lane or make turn and the existence of the other cars or foreign items exist in the blind spot zone are satisfied.
Although the present invention has been described with reference to particular embodiments, it is not to be construed as being limited thereto. Various alterations and modifications can be made to the embodiments without in any way departing from the scope or spirit of the present invention as defined in the appended claims.
