Imagine that when your car is flying on the highway, the intelligent navigation system helps you avoid traffic jams one after another, and you enjoy the morning coffee in your seat and watch it leisurely. News or check emails, no need to hold the steering wheel or pedal brakes at all times.
Imagine that the Advanced Driver Assistance System (ADAS) is currently undergoing amazing technological advances. One after another short-term development not only helps passengers improve driving safety, but also paves the way for the development of sensing, intelligence and control, making all the easy and enjoyable driving experience a reality.
The grades of the cars vary, and there are both standard compact cars and luxury full-size cars on the market. ADAS technology is of course equally high and low.
Common driver information systems include rearview cameras, panoramic field of view displays, blind spots, and lane departure warnings. These ADAS technologies provide information assistance to drivers who are always in control of car operation.
At the same time, some semi-automatic systems also provide the driver with auxiliary information while the vehicle is in motion. For example, lane keeping assist and active cruise control can automatically control the car in specific situations such as the car deviating from the lane, but the driver can always leave the system automatically according to the actual situation.
Unmanned vehicles are currently in the experimental phase and may take more than a decade to begin mass production. However, there are already high-automatic systems for high-end vehicles on the market. In these high-end cars, regardless of whether there is anyone in the driver's seat, the vehicle can be operated autonomously. These systems include automatic parking, driver monitoring and fatigue driving monitoring.
If our car can achieve both automatic parking and automatic lane keeping, and provide us with blind spots of information and warnings, why is the current fully automated vehicle not yet an industry standard? First, the unmanned vehicle currently in the experimental stage The electronic system in the middle of the car occupies most of the space of the car, and its technical cost is much higher than the cost of the vehicle itself. In the next 10 years, our main goal is to make these technical systems as small as possible, lighter in weight, and more affordable.
We believe that the best way to achieve these goals is to start at the subsystem and system levels simultaneously, minimizing design changes caused by new feature integration. As ADAS technology is undergoing rapid changes, this flexibility is a must to ensure that the latest technological advances can be applied to the next generation of models.
Ultimately, we must overcome the unique challenges of embedding technology into automotive applications. Even under certain extreme temperatures and harsh environmental conditions, our semiconductor devices must maintain high quality, high reliability and extremely high safety standards.
The above summarizes several methods for integrating ADAS into vehicles at present or in the near future. For more solutions, please refer to TI's latest ADAS white paper. The white paper also describes the legal and social barriers to overcoming the large-scale implementation of driverless vehicles, including more technical requirements related to the development of ADAS and how TI can provide solutions to these requirements.
Although the future of driverless cars may have to wait until the next decade, the development and advancement of technology is always in our eyes.

SMD: It is an abbreviation of Surface Mounted Devices. It is one of Surface Mount Technology (SMT) components. In the initial stage of circuit board production, through - hole assembly is completely manual. When the first automated machines were introduced, they could place some simple pin elements, but complex elements still needed to be placed manually for reflow soldering. Surface Mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components and special-shaped chip components
