Vehicle Remote Control Using In-Car Controls and Stop Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control systems require a dedicated remote control room, which is expensive to install and maintain, and may not ensure the reliability of remote control members like handles and pedals.
Innovation Solution
Using the vehicle's original driving operation members, such as a steering wheel, accelerator pedal, and brake pedal, for remote control, and incorporating a stop maintaining device to ensure the vehicle remains stationary during remote operation, thereby eliminating the need for a dedicated remote control terminal and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated remote control room is installed, then remote control functionality is achieved, but system cost increases
Solution Approach 1:
The patent applies universality by enabling the driving operation members (steering wheel, accelerator, brake) to serve dual purposes: normal vehicle operation and remote control of another vehicle. This eliminates the need for dedicated remote control equipment, reducing system cost while maintaining remote control functionality.
Solution Approach 2:
The vehicle itself provides the remote control capability through its existing driving operation members, without requiring external dedicated control equipment. The vehicle's own components are utilized to perform the remote control function, making the system self-sufficient and cost-effective.
2Device complexity
If driving operation members are used for remote control, then dedicated control terminal cost is reduced, but vehicle movement safety may be compromised
Solution Approach 1:
The stop maintaining device is activated in advance to prevent the vehicle from moving during remote control operation. By applying the brake before remote control begins, the system proactively counteracts any potential unintended movement, ensuring safety while allowing the use of existing driving operation members.
Solution Approach 2:
The stop maintaining device acts as an intermediary safety mechanism between the driving operation members and the vehicle's movement. It mediates by preventing the vehicle from moving when the driver is controlling another vehicle remotely, thus ensuring safety without interfering with the remote control function.
3Reliability
If the vehicle is prohibited from moving during remote control, then safety is ensured, but operational flexibility is reduced
Solution Approach 1:
The system dynamically adjusts the vehicle's operational state based on the control mode. When remote control is active, the stop maintaining device is engaged to prevent movement. When remote control is inactive, the vehicle returns to normal operational flexibility. This dynamic switching ensures safety during remote control while maintaining operational flexibility when needed.

AI summary
The vehicle includes a driving operation member that is operated by an operator to perform steering, acceleration, and deceleration, a stop maintaining device that maintains a stop state, and a control device. In the remote control mode, the control device communicates with the remote operation target vehicle, transmits information reflecting the operation amount of the driving operation member to the remote operation target vehicle, and presents information received from the remote operation target vehicle to the operator. When the stop state of the vehicle is not maintained by the stop maintaining device, the control device prohibits the remote control mode.
