Pivoting Sensor Mount for Vehicle Active Driving Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle active driving assistance systems face limitations in sensor accuracy and reliability due to fixed sensor arrangements that restrict their field of vision, particularly during lane changes and cornering, leading to reduced effectiveness and increased accident risk.
Innovation Solution
Sensors are mounted on a pivoting device that allows them to be panned or tilted relative to the vehicle's longitudinal axis, enabling dynamic adjustment of their field of vision in response to driving direction, steering angle, or front wheel angle, thereby optimizing their functionality regardless of driving situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are arranged in a fixed and immovable manner outside the vehicle interior, then their field of vision is directed to the vehicle longitudinal direction, but their field of vision is restricted to predetermined sensing angles which is disadvantageous when changing lanes or cornering
Solution Approach 1:
The patent applies the dynamics principle by making the sensor arrangement movable rather than fixed. The sensor unit is mounted on a pivoting device that allows it to change its orientation dynamically. This enables the sensors to adapt their field of vision according to the driving situation, such as rotating to scan lateral areas during lane changes or cornering, thereby resolving the contradiction between maintaining fixed directional accuracy and achieving versatile coverage.
2Device complexity
If sensors are arranged in a fixed manner with predetermined sensing angles, then the system structure is simple, but the effectiveness of active driving assistance systems is reduced during lane changes and cornering
Solution Approach 1:
The pivoting device enables the sensor unit to dynamically adjust its orientation based on driving conditions. During normal straight-line driving, the sensors maintain their predetermined sensing angles for simple and accurate measurement. When lane changes or cornering are detected, the pivoting device rotates the sensor unit to scan lateral areas, thereby maintaining high driving assistance effectiveness without requiring a completely complex reconfiguration system.
Solution Approach 2:
The sensor unit is designed to perform multiple functions: it can operate in a fixed position for standard longitudinal direction sensing, and it can be rotated to scan lateral areas during maneuvering. This multi-functionality allows the same sensor arrangement to serve both the simplicity of fixed mounting and the versatility of adaptive scanning, resolving the contradiction between device complexity and reliability.
3Ease of manufacture
If the field of vision is restricted to predetermined sensing angles, then the sensor arrangement is straightforward, but regions laterally next to the motor vehicle cannot be properly sensed
Solution Approach 1:
The pivoting device allows the sensor unit to dynamically change its orientation from a fixed longitudinal alignment to lateral scanning positions. During straight-line driving, the sensors maintain their simple predetermined angles. When lateral sensing is required during lane changes or cornering, the pivoting mechanism rotates the sensor unit to capture information from lateral regions, thereby preventing information loss without complicating the basic mounting structure.
