Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to account for changes in vehicle height, leading to inconsistencies in external environment recognition data and affecting the accuracy of movement control.
Innovation Solution
A control device with an external environment recognition unit that corrects external environment recognition data in response to changes in vehicle height, utilizing sensors and a movement control unit to adjust vehicle height and maintain accurate environmental recognition during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle height is adjusted to adapt to different road conditions or parking requirements, then vehicle adaptability and comfort are improved, but external environment recognition data becomes inconsistent affecting movement control accuracy
Solution Approach 1:
The system changes the parameter of external environment recognition data based on vehicle height adjustments. When the vehicle height changes, the control device modifies the recognition data (such as camera images, LIDAR point clouds) to compensate for the height variation, ensuring consistent environmental perception despite changes in sensor position.
Solution Approach 2:
The control device continuously monitors vehicle height through height detection units and uses this feedback to dynamically adjust the external environment recognition data. This closed-loop feedback mechanism ensures that recognition accuracy is maintained throughout the entire range of vehicle height adjustments.
2Adaptability or versatility
If vehicle height changes during automatic movement, then vehicle flexibility is improved, but movement control accuracy deteriorates due to inconsistent external environment recognition
Solution Approach 1:
The system dynamically adjusts the external environment recognition data parameters according to real-time vehicle height changes. This ensures that the movement control unit always receives accurate environmental information regardless of the vehicle's current height, maintaining reliable automatic movement control throughout the height adjustment range.
Solution Approach 2:
The control device pre-calculates and applies correction factors for external environment recognition data based on anticipated height changes. By preparing correction data in advance, the system ensures continuous control reliability without interruption during height adjustments.
3Device complexity
If sensor position is fixed on the vehicle, then system simplicity is maintained, but external environment recognition becomes inaccurate when vehicle height changes
Solution Approach 1:
The control device acts as an intermediary that processes and corrects external environment recognition data based on vehicle height information. This intermediary processing layer compensates for the fixed sensor position without requiring complex movable sensor mechanisms, maintaining system simplicity while improving recognition accuracy.
