Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of radar are installed to meet complex vehicle application requirements, then the system's adaptability and functionality are improved, but the device complexity and external space requirements increase
Solution Approach 1:
The patent applies universality by designing a single sensor that can perform multiple radar functions (long-range, medium-range, and short-range detection) through dynamic configuration. The sensor is configured with different parameters including azimuth angle, elevation angle, and measurement ranges based on required scenarios, eliminating the need for multiple dedicated radar sensors while maintaining comprehensive adaptability for various vehicle applications such as ACC, BSD, and LCA.
Solution Approach 2:
The patent implements dynamics by enabling real-time reconfiguration of sensor parameters based on operational scenarios. The control method dynamically adjusts configuration parameters such as azimuth angle, elevation angle, and measurement ranges according to different application requirements (e.g., switching between long-range detection for ACC and short-range detection for BSD). This dynamic adaptability allows a single sensor to replace multiple fixed-function radars, reducing system complexity while maintaining versatility.

The patent merges the functions of multiple radar sensors into a single sensor unit. By combining long-range, medium-range, and short-range detection capabilities within one sensor and using scenario-based parameter configuration, the system consolidates what would traditionally require separate radar installations into a single integrated component, thereby saving external mounting space on the vehicle.

If multiple types of radar are installed to meet complex vehicle application requirements, then the system's adaptability and functionality are improved, but the complexity of management and control increases
Solution Approach 1:
The patent implements dynamics by enabling real-time reconfiguration of sensor parameters based on operational scenarios. The control method dynamically adjusts configuration parameters such as azimuth angle, elevation angle, and measurement ranges according to different application requirements (e.g., switching between long-range detection for ACC and short-range detection for BSD).

Solution Approach 2:
The patent applies parameter changes by systematically varying sensor configuration parameters (azimuth angle, elevation angle, measurement ranges, operation modes) based on different application scenarios. The control method selects and applies appropriate parameter sets from predefined configurations corresponding to specific scenarios (e.g., LRR parameters for ACC, SRR parameters for BSD), simplifying management by parameterizing different radar functions rather than managing separate hardware systems.

AI summary
A sensor control method includes: obtaining first indication information, where the first indication information indicates a first scenario; determining a configuration parameter of at least one sensor based on the first indication information, where the configuration parameter is corresponding to the first scenario; and sending the configuration parameter to the at least one sensor. The sensor control method may be applied to automatic driving or intelligent driving, and may be specifically applied to assisted driving or unmanned driving. The sensor can be flexibly controlled through configurable parameters of sensors such as radar or a camera.
