Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle traveling remote control systems face challenges in maintaining efficient communication and processing situations, which can influence the timely receipt of remote control values by vehicles, leading to potential disruptions in traveling control.
Innovation Solution
A vehicle traveling remote control system that includes a remote control apparatus and vehicles equipped with transmission control units and remote traveling control units. The system periodically transmits remote control values to vehicles and allows them to select and transmit specific vehicle outside captured images based on traveling situations, especially when communication or processing situations are compromised.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system transmits all vehicle outside captured images to the remote control apparatus, then the remote control apparatus can make accurate traveling control decisions, but the communication load and processing time increase, causing delays in remote control value transmission
Solution Approach 1:
The transmission control unit extracts and transmits only the necessary captured image information (or reduced set of images) to the remote control apparatus instead of all captured images. This extraction principle reduces communication load while maintaining sufficient information for accurate traveling control decisions.
Solution Approach 2:
The system segments the captured images based on their relevance to current traveling situations. The transmission control unit divides images into categories (necessary vs. unnecessary) and selectively transmits only the necessary portions, reducing overall data transmission while preserving control accuracy.
2Reliability
If the system transmits multiple captured images frequently, then the remote control apparatus has up-to-date information for control decisions, but the communication situation deteriorates, influencing the timely receipt of remote control values
Solution Approach 1:
The system applies partial action by transmitting only a subset of captured images (those deemed necessary by the transmission control unit) rather than all images. This partial transmission maintains sufficient information reliability for control decisions while reducing communication complexity.
Solution Approach 2:
The transmission control unit dynamically adjusts which images to transmit based on current traveling situations and communication conditions. This dynamic selection process optimizes the balance between information freshness and communication load, adapting to changing system states.
3Measurement precision
If the remote control apparatus processes all received captured images, then accurate traveling control values can be generated, but the processing situation deteriorates, causing delays in generating and transmitting control values
Solution Approach 1:
The transmission control unit extracts only the essential image information needed for control decisions before transmission. This pre-extraction reduces the processing burden on the remote control apparatus, allowing it to focus computational resources on generating accurate control values from the reduced dataset.
Solution Approach 2:
The system performs preliminary filtering and selection of captured images at the vehicle side before transmission. This preliminary action prepares the data in advance, reducing the processing workload when the remote control apparatus receives the images, thereby improving processing speed without sacrificing accuracy.

AI summary
In a vehicle traveling remote control system, a remote control apparatus communicates with vehicles and periodically transmits a remote control value used to control traveling of each vehicle. The vehicle traveling remote control system includes a transmission control unit and a remote traveling control unit provided in each vehicle. The transmission control unit transmits to the remote control apparatus information including vehicle outside captured images generated by cameras mounted on the vehicle. The remote traveling control unit periodically executes traveling control of the vehicle based on remote control, with the remote control value. Upon determining that a communication situation between the vehicle and the remote control apparatus or a processing situation of the remote control apparatus influences the traveling control, the transmission control unit selects any of the vehicle outside captured images based on a traveling situation of the vehicle, and transmits the selected image to the remote control apparatus.
