Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are used for adaptive cruise control and cross traffic alert systems, then detection coverage and reliability are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent makes a single sensor perform multiple functions by configuring it to detect objects in different spatial zones (front, side, rear) and to provide multiple detection functions (adaptive cruise control, cross traffic alert, emergency braking). This multi-functional approach eliminates the need for separate sensor systems for each function, reducing overall sensor quantity while maintaining comprehensive detection coverage and system reliability
Solution Approach 2:
The patent extends detection coverage by utilizing three-dimensional spatial zones around the vehicle, including front, side, and rear areas. By configuring the sensor to monitor multiple spatial dimensions and transitioning objects between zones as the vehicle moves, the system achieves comprehensive coverage without requiring additional sensors for each direction, thus reducing device complexity while maintaining reliability
2Reliability
If multiple sensors are used for adaptive cruise control and cross traffic alert systems, then detection coverage and reliability are improved, but manufacturing cost increases
Solution Approach 1:
The patent makes a single sensor perform multiple functions by configuring it to detect objects in different spatial zones (front, side, rear) and to provide multiple detection functions (adaptive cruise control, cross traffic alert, emergency braking). This multi-functional approach eliminates the need for separate sensor systems for each function, reducing overall sensor quantity while maintaining comprehensive detection coverage and system reliability
Solution Approach 2:
The patent combines multiple detection functions (adaptive cruise control, cross traffic alert, emergency braking) into a single integrated sensor system. By merging these previously separate functions into one unified sensor with multiple spatial zones, the system reduces the total number of sensors required, thereby lowering manufacturing costs while maintaining high reliability through redundant detection capabilities
3Measurement precision
If a forward facing radar is used for adaptive cruise control, then detection of objects ahead is improved, but system reliability deteriorates when the radar becomes faulty or obscured
Solution Approach 1:
The patent prepares for potential sensor failure by implementing redundant detection zones and alternative detection paths before failure occurs. The sensor is configured with multiple spatial zones (front, side, rear) that can compensate for each other, ensuring that if one zone or detection path becomes obscured or faulty, other zones maintain detection capability, thus cushioning against system failure
Solution Approach 2:
The patent changes the operational parameters of the sensor by configuring it to monitor multiple spatial zones and to provide multiple detection functions simultaneously. This parameter change allows the system to maintain detection capability across different areas and conditions, improving reliability by not depending on a single detection path or zone

AI summary
Aspects of the present invention relate to an apparatus for providing driver assistance of a vehicle, an autonomous system, a vehicle, a method, a controller and a non-transitory computer readable medium. The apparatus comprises a first sensor and a second sensor mounted on a vehicle. The first sensor is configured to transmit and receive electromagnetic radiation to detect the presence of an object in a first area, and the second sensor is configured to transmit and receive electromagnetic radiation to detect the presence of an object in a second area. The first area and the second area overlap to define an overlapping area forward of the vehicle. The first area extends from the overlapping area to a first extreme direction having a rearward component and a leftward component, and the second area extends from the overlapping area to a second extreme direction having a rearward component and a rightward component.
