Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of radar are installed for various ADAS applications, then the detection coverage and functionality are improved, but the external space consumption and device complexity increase
Solution Approach 1:
The patent implements a universal sensor platform that can perform multiple radar functions (long-range, middle-range, and short-range detection) using a single physical sensor. The sensor is configured with different parameter sets (azimuth angles, elevation angles, measurement periods) to serve various ADAS applications including ACC, FCW, AEB, BSD, LCA, and RCTA, eliminating the need for multiple separate radar installations.
Solution Approach 2:
The patent changes operational parameters of the sensor including azimuth angles (0°, ±15°, ±30°), elevation angles (0°, 1.5°), and measurement periods (50ms, 100ms, 200ms) to adapt the single sensor for different detection scenarios. This parameter-based configuration allows the same hardware to achieve different detection ranges and coverage areas.

The patent merges multiple radar functions into a single sensor unit with unified control. The sensor control unit manages all detection tasks (long-range, middle-range, short-range) through centralized parameter configuration, reducing the complexity of managing multiple independent radar systems.
3Area of stationary object
If a single sensor is used for various scenarios, then the external space is saved and device complexity is reduced, but the adaptability to different measurement requirements must be enhanced
Solution Approach 1:
The patent changes operational parameters of the sensor including azimuth angles (0°, ±15°, ±30°), elevation angles (0°, 1.5°), and measurement periods (50ms, 100ms, 200ms) to adapt the single sensor for different detection scenarios. This parameter-based configuration allows the same hardware to achieve different detection ranges and coverage areas.
Solution Approach 2:
The patent implements dynamic parameter adjustment where the sensor configuration (azimuth, elevation, measurement period) is adaptively changed based on the current driving scenario. The sensor transitions between different operational states (long-range mode, middle-range mode, short-range mode) to meet varying measurement requirements.

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.
