Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-vehicle remote control systems do not allow remote control of devices when a vehicle is in operation, except in emergency situations, which limits their functionality during normal use.
Innovation Solution
An on-vehicle remote control apparatus comprising a receiver, a remote-control executing device, a use-state determining device, an emergency-mode determining device, and a remote-control-execution determining device, which permits remote control of on-vehicle devices in emergency modes even if the vehicle is in use, by receiving remote-control request signals and determining the vehicle's operational state and emergency status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote control is permitted when the vehicle is in use, then operational flexibility and emergency response capability are improved, but vehicle security and safety may be compromised
Solution Approach 1:
The system dynamically adjusts remote control permissions based on real-time vehicle state. When the vehicle is detected to be in emergency mode (via emergency switch or collision sensor), the system transitions from a restricted state to an accessible state, allowing remote control operations. This dynamic adaptation resolves the contradiction by enabling remote control only when necessary while maintaining security during normal operation.
Solution Approach 2:
The system changes the operational parameters of remote control based on vehicle conditions. The control permission parameter is modified from 'prohibited' to 'permitted' when emergency conditions are detected. This parameter change allows the system to maintain high security during normal use while providing emergency access when needed, thus resolving the contradiction between security and operational flexibility.
2Reliability
If remote control is prohibited when the vehicle is in use, then vehicle security is maintained, but emergency response capability is limited
Solution Approach 1:
The system performs preliminary detection of emergency conditions through emergency switches and collision sensors before permitting remote control. This preliminary action ensures that remote control is only enabled when genuine emergency situations are detected, maintaining security while preparing the system for emergency response. The preliminary detection mechanism prevents false activation while ensuring genuine emergencies are captured.
Solution Approach 2:
The system introduces an intermediary emergency mode determination mechanism that mediates between the restrictive security protocol and the need for emergency access. This intermediary layer evaluates emergency conditions and acts as a gatekeeper, allowing remote control only when emergency criteria are met. This intermediary resolves the contradiction by providing a controlled transition path from restricted to accessible state.
3Measurement precision
If the system monitors vehicle use state and emergency mode, then remote control permission accuracy is improved, but system complexity increases
Solution Approach 1:
The emergency mode determination device leverages existing vehicle systems for multiple purposes. The emergency switch and collision sensor, originally designed for safety functions, are also utilized for remote control permission determination. This multi-functionality approach improves state detection accuracy without proportionally increasing system complexity, as the same hardware serves dual purposes.
Solution Approach 2:
The system utilizes the vehicle's own existing sensors and switches to determine emergency mode and control permissions, rather than requiring entirely new monitoring infrastructure. The vehicle's built-in emergency detection capabilities serve the additional function of remote control authorization, reducing the complexity burden while maintaining high detection accuracy.

AI summary
An on-vehicle remote control apparatus includes a use-state determining device configured to determine whether a vehicle is in use. The vehicle has a remotely controllable on-vehicle device. An emergency-mode determining device is configured to determine whether the vehicle is in an emergency mode. A remote-control-execution determining device is configured to determine whether a remote-control executing device is permitted to execute remote control of the on-vehicle device. If the use-state determining device determines that the vehicle is in use, the remote-control-execution determining device prohibits the remote-control executing device from executing the remote control of the on-vehicle device. Even when the use-state determining device determines that the vehicle is in use, if the emergency-mode determining device determines that the vehicle is in the emergency mode, the remote-control-execution determining device permits the remote-control executing device to execute the remote control of the on-vehicle device.
