What is the vehicle sensor network? The role of millimeter wave radar in intelligent connected vehicles

What is a vehicle sensor network?

A vehicle-mounted sensor network is a wireless sensor network used in automobiles or vehicle systems. It collects, processes and transmits data about the vehicle and its surroundings by deploying multiple sensor nodes and communication devices on the vehicle.

The vehicle sensor network can be used to monitor various aspects of the vehicle, such as vehicle speed, fuel consumption, engine temperature, fluid level, tire pressure, etc. It can obtain relevant data such as vehicle operating status, environmental conditions and driving behavior in real time, and transmit this data to the control unit inside the vehicle or external remote server for processing and analysis through wireless communication technology.

Through the vehicle sensor network, the vehicle system can obtain more comprehensive and accurate information, thereby providing a more efficient, safe and intelligent driving experience and functions. For example, based on the vehicle sensor network, vehicle location tracking, intelligent navigation, vehicle diagnosis, collision warning, automatic driving and other functions can be realized.

In short, the vehicle-mounted sensor network uses sensors and wireless communication technology to collect and transmit information about the vehicle and its surrounding environment, providing rich data support for the vehicle system, promoting the intelligence of the vehicle and improving the driving experience.

The role of millimeter-wave radar in intelligent connected vehicles

Millimeter-wave radar for intelligent connected vehicles is a key technology for vehicle perception and safe driving. It transmits and receives millimeter-wave signals to achieve high-precision perception and detection of the vehicle's surroundings, thereby providing a variety of functions and applications.

The following are the main functions of millimeter-wave radar for intelligent connected vehicles:

Collision warning and brake assistance: Millimeter-wave radar can monitor the position, distance and speed of obstacles such as vehicles and pedestrians in front or around in real time, and provide accurate data. Based on this information, the system can issue a collision warning, prompt the driver to pay attention in time, and assist in braking operations to reduce the risk of collision.

Adaptive cruise control: Millimeter-wave radar can be used to implement the adaptive cruise control (ACC) system. It can measure the distance and relative speed to the vehicle in front, realize the intelligent following function, and automatically adjust the vehicle's cruising speed according to traffic conditions, improving driving comfort and safety.

Blind spot detection and lane keeping: Millimeter-wave radar can also detect the blind spots of the vehicle, including blind spots, side and rear areas, etc. It helps the driver avoid potential dangers on the side and rear by providing visual blind spot warnings and auxiliary lane keeping functions.

Road condition monitoring: Millimeter-wave radar can identify obstacles, slippery conditions, water accumulation and other road condition information, and provide timely warnings to the driver, enhancing the driver's perception of and countermeasures to road conditions.

Automatic parking assistance: Using the high-precision detection function of millimeter-wave radar, intelligent connected cars can realize automatic parking assistance system. It can detect obstacles and parking spaces around the vehicle, accurately calculate the driving trajectory, and assist in automatically completing operations such as reversing into a parking space or parallel parking.

In short, the millimeter-wave radar of intelligent connected vehicles provides drivers with important real-time information and auxiliary functions by sensing and detecting data from the vehicle's surrounding environment to improve driving safety, comfort and driving experience.
