Do you know where the on-board computer is installed?
As cars gradually develop toward intelligence, more and more software and hardware are integrated.
Control systems for autonomous vehicles, especially high-level autonomous vehicle control systems, are generally equipped with on-board computing modules (or autonomous driving computing platforms), such as mobile data centers (MDC). The
vehicle-mounted computing module can sense the surrounding environment through vehicle-mounted sensors such as cameras, lidar , millimeter wave radar , and ultrasonic waves. It will obtain the data and calculate it to formulate corresponding driving strategies, such as predicting the relationship between the car and other vehicles, The movement status of pedestrians and others in the future period is analyzed, and collision avoidance path planning is carried out.
As the requirements for autonomous driving continue to increase, the on-board computing module needs to implement more and more functions. The demand for computing power and is getting bigger and bigger, the structure is getting more and more complex, and the size is getting larger and larger.
So where is the on-board computing module located?
can intuitively think of the center console. But in fact, there is not enough space in the center console, and many large-sized computing modules can only be placed under the seats or in the front compartment of the engine. The working conditions in these places are relatively harsh, so the industry requires a higher waterproof level of and for vehicle-mounted computing modules, usually above IPX7.
On the other hand, the speed of data transmission is becoming more and more important. After signals are collected from various sensors such as cameras and lidar, they need to be quickly transmitted to the on-board computing module, which requires increasingly higher communication rates and bandwidth. Traditional low-speed connectors on the market are no longer able to meet the communication needs between sensors and on-board computing modules in high-level autonomous driving scenarios. There is no mature implementation solution for IPX7-rated waterproof design between high-speed connectors.
On June 21, Huawei Technologies Co., Ltd. disclosed a patent titled "An Electronic Device and a Vehicle" in the State Intellectual Property Office . It designed an electronic device that can make the vehicle waterproof when in use. The connector is also waterproof and dustproof.
According to the patent description, it provides an electronic device and a vehicle, in which the housing of the electronic device is provided with an openable and snappable cover, and the electronic device has a non-waterproof connector installed inside the housing. , the external cable is connected to the connector inside the casing, and then introduced from the inside of the casing to the outside of the casing.
In order to facilitate cable extraction, the fastening surface of the housing and the protective cover has at least one cable channel, and housing sealing components such as a first sealing rubber strip and a second sealing rubber strip are also provided around the cable outlet. When the protective cover is fastened, the housing and the protective cover can press the first sealing rubber strip to form a seal between the housing and the protective cover. At the same time, the first sealing rubber strip and the second sealing rubber strip can press the cable , forming a seal between the cable, the casing and the protective cover, so that liquids and dust outside the casing will not enter the inside of the casing, so that electronic equipment can also be waterproof when using connectors that do not have waterproof properties. Dust ability.
