1) The blind zone obstacle information is provided by using the ultrasonic system, and the cost is lower compared with that of a millimeter wave system
2) The blind area image is provided through the host display screen, the blind area is visualized, and the information acquisition is more direct.
The system consists of an ultrasonic distance and range detection sensor, an ultrasonic ECU, a display host computer, a camera, a steering lamp signal provided by a vehicle body controller and corner information provided by a steering wheel corner sensor, and has the capability of providing a vehicle side blind area image in real time.
The detection distance of the ultrasonic sensor is more than 3m, the horizontal coverage range is more than 80 degrees, and the ultrasonic sensor can provide the surrounding environment information of the vehicle. The ultrasonic sensor is generally arranged in the range of 3m of the vehicle rear protection or the side edge covering the periphery of the vehicle, and the specific installation position of the ultrasonic sensor can be adjusted in detail according to the specific blind area requirement. After the obstacle is detected, the ECU identifies specific obstacle information through a signal processing means, and sends the obstacle information to other ECUs, such as a host ECU, through a CAN line by a sensor control module through an obstacle signal for displaying and performing other interactive logics.
The camera is mainly installed on the outer rear mirror shell of left and right sides, and its installation angle satisfies the requirement that can observe car side blind area, and specific resolution can be according to the bicycle requirement and make concrete selection type, for example 1340 x 1020.

The ultrasonic probe detects obstacles at the car side 3m, particularly obstacles in the range of 3m of a left door and a right door of the car, and at least 2 ultrasonic sensors are required to be arranged on the side edge of the car body to cover a blind area at the car side due to the detection property limitation of the ultrasonic sensors. The camera can clearly observe the 15m cataract on the vehicle side, and in order to better provide the obstacle information in the peripheral range of the vehicle, a wide-angle lens is suggested, and the visual FOV of the wide-angle lens is not less than 180 degrees. The resolution of the display of the vehicle is required to be higher than 480 × 640 so as to provide clear definition of blind zone information, wherein the blind zone mainly refers to a range within 3m of the side of the vehicle and a range within 3m of the rear protection of the vehicle, as shown in fig. 2.
The ultrasonic sensor receives the detection information of the probe, obtains the barrier information after filtering, and judges whether to send a command requesting display according to the definition of the blind area in the system. Meanwhile, the steering intention of the driver is judged according to the steering information of the steering lamp signal and the turning angle information of the steering wheel, and a blind area on the driving side is preferentially provided according to the steering intention of the driver, so that the driver can clearly observe the environment condition on the driving side, a drivable safety area is provided for the driver on a display screen of the vehicle machine, and the driver is assisted to drive safely.
When the ultrasonic system detects the obstacle information in the left blind area, a blind area display request signal is sent out, and the vehicle display screen displays the left blind area condition.
When the ultrasonic system detects that the right blind area has the obstacle information, a blind area display request signal is sent out, and the vehicle display screen displays the right blind area condition. When the ultrasonic system detects that the left blind area and the right blind area have barrier information, the host computer displays the left blind area and the right blind area simultaneously, and the barrier information can be displayed in different areas. . When the vehicle steering intention is obvious (the steering lamp signal or the steering wheel corner signal of the vehicle body controller has higher priority than the steering lamp signal), only the situation of the blind area obstacle to be steered is displayed, and the steering intention is obtained by the steering wheel or the steering lamp signal.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
