Vehicle Camera Heater Malfunction Notification Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in vehicles equipped with multiple cameras may experience annoyance due to frequent notifications of heater malfunctions, even when travel assistance can still be provided through other cameras, as existing systems do not differentiate between malfunctions in heaters serving different cameras.
Innovation Solution
A shooting system for mobile objects that includes two cameras and heaters, with a control unit that determines the severity of heater malfunctions and suppresses notifications for non-critical malfunctions, allowing travel assistance to continue without passenger disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras and heaters are equipped in the vehicle, then the reliability of travel assistance is improved, but the frequency of malfunction notifications increases causing passenger annoyance
Solution Approach 1:
The control unit applies different notification policies to different heaters based on their specific roles. The first heater (for automated driving camera) triggers notifications when malfunctioning, while the second heater (for supplementary camera) does not trigger notifications. This local differentiation of quality in notification handling resolves the contradiction by maintaining reliability through redundancy while eliminating harmful annoyance from non-critical failures.
Solution Approach 2:
The system segments the heaters into different functional categories: the first heater is critical for automated driving operations, while the second heater is supplementary. This segmentation allows the control unit to handle malfunctions differently based on the segment's importance, thereby maintaining overall system reliability while reducing unnecessary notifications that cause passenger annoyance.
2Loss of information
If notification is given for every heater malfunction, then the information completeness is improved, but the passenger experience deteriorates due to frequent notifications
Solution Approach 1:
The control unit applies different notification policies to different heaters based on their specific roles. The first heater (for automated driving camera) triggers notifications when malfunctioning, while the second heater (for supplementary camera) does not trigger notifications. This local differentiation of quality in notification handling resolves the contradiction by maintaining reliability through redundancy while eliminating harmful annoyance from non-critical failures.
Solution Approach 2:
Instead of notifying for all heater malfunctions uniformly, the system inverts the approach by selectively suppressing notifications for non-critical heaters. This inversion allows the system to maintain information completeness for critical issues while improving passenger experience by filtering out non-essential notifications.
3Productivity
If the system continues travel assistance with remaining cameras, then the productivity is improved, but the risk of undetected critical failures increases
Solution Approach 1:
The system segments the heaters into different functional categories: the first heater is critical for automated driving operations, while the second heater is supplementary. This segmentation allows the control unit to handle malfunctions differently based on the segment's importance, thereby maintaining overall system reliability while reducing unnecessary notifications that cause passenger annoyance.
Solution Approach 2:
The control unit continuously monitors heater status and provides feedback through selective notifications. When the first heater malfunctions, feedback is provided to the passenger. When the second heater malfunctions, the system continues operation without notification since the supplementary camera can compensate. This feedback mechanism maintains productivity while managing reliability risks appropriately.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces passenger annoyance by minimizing unnecessary notifications and ensuring continuous travel assistance even when one heater malfunctions, as the system prioritizes notifications for critical malfunctions affecting primary cameras used in automated driving.
Implementation Method 1
a first heater configured to be capable of heating the first transmissive portion

AI summary
There is provided with a shooting system for a mobile object. A first shooting unit shoots surroundings of a mobile object via a first transmissive portion. A second shooting unit shoots surroundings of the mobile object via a second transmissive portion. A first heater is capable of heating the first transmissive portion. A second heater is capable of heating the second transmissive portion. A notification unit notifies a passenger of information. A control unit determines a malfunction of the first heater and the second heater, and causes the notification unit to give notification regarding an occurrence of the malfunction. The control unit suppresses the notification by the notification unit when it is determined that the second heater has malfunctioned compared to when it is determined that the first heater has malfunctioned.
