Vehicle Remote Control Battery Voltage Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles lack a mechanism to notify the driver when the battery in the transmission means is running low, leading to unexpected loss of remote operation functionality due to undervoltage, as the battery exhaustion level cannot be easily determined.
Innovation Solution
A remote control system that includes a battery voltage monitoring mechanism, where the transmission means detects undervoltage and transmits a notification signal, and the receiving means provides visual and auditory alerts, such as blinking LEDs or turn signals, to inform the driver of low battery voltage, ensuring continued reliable remote operation.

Engineering Contradiction Analysis
1Ease of operation
If remote operation functionality is provided using a battery-powered transmission means, then operability is enhanced, but reliability deteriorates when the battery becomes exhausted without notification
Solution Approach 1:
The system implements feedback by having the receiving means monitor battery voltage from the transmission means and send status information back to the transmission means. When voltage drops below a threshold, the receiving means triggers notification through the vehicle's turn signals or buzzer, ensuring the driver is informed of battery exhaustion before remote operation fails.
Solution Approach 2:
The system performs preliminary action by detecting battery voltage degradation before complete exhaustion occurs. The undervoltage detection mechanism continuously monitors battery status and prepares notification in advance, allowing the driver to replace the battery before remote operation becomes completely unreliable.
2Reliability
If battery voltage monitoring and notification mechanisms are added, then reliability is improved, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by utilizing existing vehicle components for notification purposes. The turn signals and buzzer, which already exist in the vehicle for other functions, are repurposed to provide battery status notification, eliminating the need for separate dedicated notification hardware and reducing overall system complexity.
Solution Approach 2:
The receiving means performs self-service by using its own existing notification capabilities (turn signals, buzzer) to alert the driver of battery issues. Rather than requiring a separate notification system, the receiving means leverages its integrated components to provide the warning function.

AI summary
A remote control system includes transmission means (11) which a driver can carry, the transmission means having a battery (D) and an operation section (b) which the driver can operate, the transmission means configured to transmit an operation signal in response to an operation of the operation section (b), and receiving means (12) disposed in a vehicle, and configured to receive the operation signal transmitted by the transmission means (11), and to activate an electrical equipment disposed in the vehicle in accordance with the operation signal. The transmission means (11) is configured to transmit information about a voltage of the battery (D) to the receiving means (12), and the receiving means (12) is configured to provide a notification when the voltage of the battery (D) has fallen to a predetermined level or below. The system is in particular used with a shutter (8) covered ignition key cylinder.
