Remote Driving Display Overlay for Accurate Vehicle Stop Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote driving systems, drivers have a weakened sense of distance, speed, and acceleration, leading to excessive stopping before the desired stop position when attempting to stop the vehicle at a desired stop position.
Innovation Solution
A display system that includes a camera to capture a traveling image, a display device, storage devices to store a reference deceleration, and processors to calculate and display an estimated stop position superimposed on the traveling image, based on the vehicle's speed and reference deceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote driving is implemented with display device, then driver can operate vehicle without boarding, but driver's sense of distance and speed becomes weak leading to excessive stopping
Solution Approach 1:
The system calculates the estimated stop position based on current vehicle speed and reference deceleration, then displays this information superimposed on the traveling image. This provides real-time feedback to the remote driver about where the vehicle will stop, compensating for the weakened sense of distance and enabling more accurate stopping control.
Solution Approach 2:
The estimated stop position display acts as an intermediary between the vehicle's actual stopping behavior and the remote driver's perception. By showing where the vehicle will naturally stop based on current speed and deceleration characteristics, it bridges the gap between the driver's limited sensory feedback and the vehicle's actual motion state.
2Manufacturing precision
If estimated stop position is displayed superimposed on traveling image, then driver can stop at desired position, but requires calculation and processing of vehicle speed and deceleration
Solution Approach 1:
The system uses the vehicle's own existing data (vehicle speed from speed sensors and deceleration from acceleration sensors) to calculate the estimated stop position. This self-service approach avoids the need for external or additional complex measurement systems, using already-available vehicle operational data to achieve improved stop precision.
Solution Approach 2:
The system changes the parameter representation by displaying the calculated estimated stop position as a visual overlay on the camera image. This transforms abstract vehicle speed and deceleration parameters into a concrete visual indicator that directly shows the driver where the vehicle will stop, simplifying the driver's task while maintaining calculation accuracy.

AI summary
A display system according to the present disclosure includes a camera that captures a traveling image of a vehicle in a traveling direction, a display device, one or more storage devices that store a reference deceleration indicating a predetermined deceleration, and one or more processors. The one or more processors are configured to execute a process of acquiring a vehicle speed of the vehicle, a process of an estimated stop position indicating a stop position when braking is applied at the reference deceleration from the vehicle speed, and a process of displaying the estimated stop position to be superimposed on the traveling image on the display device.
