Remote Control Heading Correction Using Signal Strength Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for motion heading, such as RC model cars, often result in the vehicle moving in the opposite direction of the intended command due to misjudgment of orientation, leading to accidents and operational challenges.
Innovation Solution
A method that calculates a new motion heading by determining the angle between the transmission and receiving ends using multiple sensors or a position-sensitive device, allowing the receiving end to align with the intended direction set by the transmission end, effectively correcting the orientation mismatch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the receiving end uses the head of the car as a reference direction for motion control, then the control system is simple, but the vehicle moves in the opposite direction to that commanded by the joystick, causing orientation mismatch
Solution Approach 1:
The patent inverts the reference direction from the vehicle's head to the transmission end (remote controller). By using the transmission end as the reference point and calculating the angle between the transmission end and the vehicle body, the system ensures that the vehicle moves in the intended direction rather than the opposite direction, resolving the orientation mismatch problem
Solution Approach 2:
The patent implements feedback by having the receiving end calculate the angle between the transmission end and the vehicle body, then use this angle information to adjust the motion control. The system continuously monitors the relative orientation and uses this feedback to correct the vehicle's heading, ensuring accurate orientation control
2Device complexity
If the operator makes judgment of orientation based on the receiving end's head direction, then the control logic is simple, but accidents occur due to moment of negligence and misjudgment of orientation
Solution Approach 1:
The patent applies self-service by enabling the receiving end to autonomously calculate its own angle relative to the transmission end and automatically adjust its heading based on this calculated angle. This eliminates the need for the operator to manually judge orientation, reducing human error and improving reliability while maintaining simple control logic
3Speed
If the transmission end directly controls the receiving end's heading without angle calculation, then the response is fast, but the receiving end cannot accurately align with the intended direction
Solution Approach 1:
The patent applies preliminary action by having the receiving end pre-calculate the angle between the transmission end and its body before executing the motion command. This angle calculation is performed in advance, allowing the system to quickly determine the correct heading adjustment without delaying the response, thus maintaining fast response speed while achieving precise orientation alignment

AI summary
A method to control a motion heading at a receiving end by referring to an angle between the receiving end and a transmission end includes the following steps solving an angle, α, between an original heading and a user inputted direction of transmission end; having a signal-receiving unit at the receiving end to pick up signals sent from the transmission end; determining a signal source orientation according to strength of the signals received by the signal-receiving unit which comprises multiple sensors or a position sensitive device arranged in a form to pick up the signals from the transmission end; solving an angle, β, between the signal source orientation and an original motion heading of the receiving end; and solving a new motion heading according to the angles αand β.
