Vehicle Wading Prompting With Real-Time Depth and Allowable Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in accurately determining vehicle wading conditions, especially during urban flooding, due to insufficient driving experience, leading to potential risks.
Innovation Solution
A method and apparatus that provide real-time wading information, including depth and allowable depth, to the driver through a terminal device or display screen, with prompts for dangerous conditions and options for automatic parking or mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver performs visual inspection to determine front water depth, then the driver can assess wading conditions, but the driver cannot accurately determine depth due to insufficient driving experience
Solution Approach 1:
The patent replaces the driver's manual visual inspection method with an automated radar detection system. The radar device automatically measures water depth without requiring driver skill or visual estimation, substituting mechanical human judgment with electronic detection technology to achieve precise depth measurement.
Solution Approach 2:
The patent introduces a control device as an intermediary between the radar detection system and the driver. The control device processes radar signals, determines wading information, and presents it to the driver through the user interface, bridging the gap between complex detection technology and simple driver interaction.
2Loss of information
If the vehicle provides real-time wading information through multiple channels, then the driver can obtain comprehensive information, but the system complexity increases
Solution Approach 1:
The control device serves multiple functions: it controls the radar device, processes detection signals, determines wading information, selects appropriate output channels based on vehicle state, and manages different alert levels. This multi-functionality consolidates what would otherwise be separate systems into a single integrated control unit.
Solution Approach 2:
The system dynamically adapts its information delivery method based on the vehicle's operational state. When the vehicle is moving, information is displayed on the display screen; when parked, information is sent to the terminal device. This dynamic adaptation allows the system to use different communication channels appropriately without requiring permanent complex infrastructure for all channels.
3Reliability
If the radar operates continuously to monitor wading conditions, then real-time detection is achieved, but energy consumption increases
Solution Approach 1:
The radar device operates periodically rather than continuously. The control device controls the radar to perform detection at specific intervals or under specific conditions (such as when wading is suspected), rather than maintaining constant operation. This periodic operation maintains detection reliability while significantly reducing overall energy consumption compared to continuous monitoring.
Data Source
AI summary
A method for prompting vehicle wading, a control device, a storage medium and a vehicle. The current wading information of the vehicle is obtained, the wading information includes a wading depth, a preset wading level corresponding to the wading depth and a current maximum allowable wading depth of the vehicle; the current state of the vehicle is obtained, the current state of the vehicle includes a flameout parking state and a driving state; the current wading information of the vehicle is sent to the terminal device of the user if the current state of the vehicle is the flameout parking state; the current wading information of the vehicle is displayed on a display screen of the vehicle if the current state of the vehicle is the driving state.
