Vehicle Remote Control Distance Monitoring via Data Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote operation of vehicle functions is risky when the remote control unit is too far away from the vehicle or the user has a restricted view, leading to potential signal interference and loss of control.
Innovation Solution
A method that specifies a data transmission rate based on the distance between the remote control unit and the vehicle, restricting vehicle function control or emitting warning signals when the rate falls below a defined limit, using wireless transmission technologies like WLAN or Bluetooth, and employing a smartphone with suitable software to monitor and manage the data transmission rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote control unit is allowed to operate vehicle functions at any distance, then the ease of operation is improved, but the reliability deteriorates due to signal interference and loss of control
Solution Approach 1:
The system continuously monitors the data transmission rate between the remote control unit and the vehicle station, using this feedback to dynamically adjust the level of vehicle function control. When the transmission rate falls below a threshold, the system automatically restricts control functions and issues warnings, creating a closed-loop control system that maintains reliability while enabling remote operation.
Solution Approach 2:
The system transitions from a static remote control approach to a dynamic one where the level of control access changes based on real-time transmission conditions. The control unit adaptively adjusts the permitted vehicle functions according to the current data transmission rate, allowing full operation when conditions are good and restricting functions when conditions deteriorate.
2Reliability
If the data transmission rate is monitored continuously to ensure safe distance, then the reliability is improved, but the use of energy increases
Solution Approach 1:
The system monitors the data transmission rate parameter, which naturally varies with distance and environmental conditions. By using this existing parameter as a proxy for distance and signal quality, the system avoids the need for separate distance measurement systems, thereby reducing energy consumption while maintaining reliable monitoring of safe operation conditions.
3Ease of operation
If the remote control unit operates without distance restrictions, then the ease of operation is improved, but the object-affected harmful factors increase due to potential signal loss
Solution Approach 1:
The system takes preliminary action by monitoring the data transmission rate and predicting potential signal loss before it occurs. When the transmission rate approaches problematic levels, the system proactively issues warnings and restricts control functions, preventing the harmful effects of signal loss and interference before they can compromise vehicle safety.
Data Source
AI summary
A method for controlling functions of a vehicle by a remote control unit is provided herein. Signals are transmitted wirelessly between the remote control unit and a station in the vehicle. A data transmission rate depends on a distance between the remote control unit and the station. The data transmission rate is specified. If the data transmission rate is below a defined limit value, the vehicle functions to be controlled are no longer performed or are performed to a restricted extent only and/or the remote control unit emits warning signals.
