Remote Vehicle Control With Selectable Surroundings Perspectives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for motor vehicles lack flexibility and safety when users need to control vehicles from a distance, particularly in critical driving situations, as they are limited by fixed sensor perspectives and communication constraints.
Innovation Solution
A method that allows users to select arbitrary perspectives for viewing motor vehicle surroundings using sensor data from various environment sensors, enabling flexible and safe remote control through a remote-control device, which can communicate and calculate surroundings images based on user input, independent of sensor positions, using 4G or future communication standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed sensor perspectives are used for remote control, then device complexity is reduced, but user flexibility and situational awareness deteriorate
Solution Approach 1:
The system dynamically switches between fixed sensor perspectives and freely selectable arbitrary perspectives based on user needs. The perspective selection mechanism allows transition from static camera views to dynamically generated views from any position around the vehicle, resolving the contradiction between simplicity and flexibility.
Solution Approach 2:
The remote control system serves multiple functions: it displays both fixed sensor perspectives for simple monitoring and arbitrarily selectable perspectives for comprehensive situational awareness. This multi-functionality allows the same system to adapt to different user needs without requiring separate systems.
2Loss of information
If comprehensive surroundings information is provided from multiple perspectives, then user situational awareness is improved, but data transfer requirements and latency increase
Solution Approach 1:
The system provides partial perspective information through fixed sensors and adds arbitrary perspective information only when needed. This partial action approach ensures comprehensive situational awareness while minimizing unnecessary data transfer and latency by not continuously transmitting all possible perspectives.
Solution Approach 2:
The server acts as an intermediary that generates arbitrary perspectives from sensor data and transmits only the necessary view information to the remote control device. This mediator approach reduces data transfer requirements by processing and selecting only essential perspective information rather than transmitting raw sensor data from all sources.
3Adaptability or versatility
If arbitrary perspectives are calculated and displayed, then user adaptability is enhanced, but computing power requirements increase
Solution Approach 1:
The computing task is segmented between the server and the remote control device. The server performs the computationally intensive task of calculating arbitrary perspectives from sensor data, while the remote control device only handles displaying the generated views and receiving user input. This segmentation resolves the contradiction by moving heavy computation to a more powerful system.
Solution Approach 2:
The server serves as an intermediary that performs the complex computation of generating arbitrary perspectives from sensor data before transmitting results to the remote control device. This mediator approach allows the client device to maintain low computing power requirements while still providing comprehensive perspective selection flexibility.

AI summary
A method for assisting a user in the remote control of a motor vehicle by a remote-control device is disclosed. Depending on sensor data provided by means of at least one environment sensor of the motor vehicle, a first surroundings image of at least one part of the surroundings of the motor vehicle from a determined perspective is provided and displayed by means of the remote-control device. In this case, the determined perspective is selected from a number of selectable perspectives as a perspective that is independent of a position of the at least one environment sensor, depending on a user input effected by the user and detected by means of the remote-control device.
