Vehicle Remote Control With Distance-Based Command Gating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle remote control systems lack the ability to restrict operations based on the distance between the remote control device and the vehicle, leading to unintended vehicle operations when the user is outside a predetermined range.
Innovation Solution
A vehicle remote control system that includes a server with a transceiver and controller, which receives location data from both the vehicle and the remote device, determining the distance between them and only transmitting operating instructions if within a specified threshold, thereby preventing unintended operations when the user is outside this range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control requests are transmitted without distance restriction, then ease of operation is improved, but reliability deteriorates due to unintended vehicle operations
Solution Approach 1:
The system performs preliminary distance verification by comparing the calculated distance between remote device and vehicle against a predetermined threshold before allowing the vehicle operation to proceed. This preliminary check prevents unintended operations while maintaining ease of use for legitimate remote control scenarios.
2Reliability
If distance verification is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
A server acts as an intermediary between the remote device and vehicle, handling the distance verification logic centrally. The server receives location data from both the remote device and vehicle, calculates the distance, and determines whether to permit the operation. This approach adds minimal complexity to the vehicle and remote device while ensuring reliable distance-based control.

AI summary
A vehicle remote control system includes a server including a transceiver and a controller. The transceiver is configured to receive location data from a vehicle and location data from a remote device. The controller is configured to receive an operating instruction signal from the remote device, the operating instruction signal including instructions to operate one or more components of the vehicle. A distance between the vehicle and the remote device is determined based on the location data from the vehicle and the location data from the remote device. The operating instruction signal is transmitted to the vehicle in response to a determination that the distance between the vehicle and the remote device is equal to or less than a corresponding threshold distance.
