Remote Vehicle Control With Adjustable Obstacle Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote vehicle control systems struggle with incorrect obstacle detection, leading to unexpected stops during maneuvers in narrow spaces, particularly when navigating through garages with virtual or ghost objects, which disrupt continuous operation.
Innovation Solution
A method and device that allows for autonomous vehicle operation with adjustable safety distances and the ability to ignore incorrect obstacle detections, enabling continuous remote control by adjusting lateral safety distances and ignoring virtual objects, ensuring safe passage through narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle maintains predetermined safety distances from obstacles, then collision avoidance is ensured, but the vehicle cannot pass through narrow spaces like garage gates
Solution Approach 1:
The patent applies dynamics by making the safety distance adjustable rather than fixed. The control unit dynamically changes the predetermined safety distance from a first value to a second value (smaller than the first) when navigating narrow spaces, allowing the vehicle to adapt to different spatial constraints while maintaining collision avoidance through continuous monitoring
Solution Approach 2:
The patent changes the parameter of safety distance from a fixed predetermined value to an adjustable value. The control unit modifies the safety distance parameter based on the operational context - using a larger first safety distance for normal conditions and a smaller second safety distance for narrow space navigation, resolving the contradiction between safety and adaptability
2Reliability
If the vehicle stops at every detected obstacle, then safety is maintained, but continuous operation is disrupted by incorrect obstacle detections
Solution Approach 1:
The patent implements feedback by continuously monitoring obstacle detections and comparing them against operational context. The control unit receives feedback from sensors about detected obstacles and determines whether to respond with a stop or continue operation based on the current safety distance setting and spatial context, filtering out incorrect detections while maintaining safety
Solution Approach 2:
The system dynamically adjusts its response to obstacle detections based on the current operational mode. When navigating narrow spaces with reduced safety distances, the control unit dynamically determines that certain detections should be ignored, allowing continuous operation while maintaining safety through context-aware decision-making

AI summary
A method and device for remotely controlling a motor vehicle. A remote control device is provided. A transceiver device is located in the vehicle and is configured to exchange signals with the remote control device. A signal from the remote control device to the transceiver device activates a first operating mode in the vehicle, in which operating mode the vehicle moves autonomously, while maintaining specifiable surrounding conditions. The first operating mode is left if the specifiable surrounding conditions can no longer be maintained. After leaving the first operating mode, a second operating mode can be activated by a further signal to the transceiver device. In the second operating mode, the vehicle also moves autonomously but while maintaining further surrounding conditions which are at least partially changed in comparison to the surrounding conditions that can be specified in the first operating mode.
