Remote Vehicle Movement Control Using Tilt-Based Virtual Pedals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for remotely controlling a vehicle's movement, especially at low speeds in challenging conditions, require external assistance and lack precision, as they rely on binary user confirmation and do not accurately mimic the continuous control actions of a driver.
Innovation Solution
A method and device that allow a user to remotely control a vehicle's longitudinal movement using a hand-held device, where the device detects the tilt angle and converts it into a virtual pedal position, enabling precise control of the vehicle's acceleration and braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user uses external assistance to navigate the vehicle, then the user can get feedback information about vehicle movement, but the process becomes more complex and requires multiple people
Solution Approach 1:
The system enables the driver to perform both driving and navigation tasks independently using the mobile device as a remote control. The driver can monitor vehicle movement through the application and provide self-feedback, eliminating the need for external assistants while maintaining navigation reliability
Solution Approach 2:
The mobile device application acts as an intermediary between the driver and vehicle control systems. It provides a user interface that displays vehicle status, movement information, and control options, serving as a mediator that consolidates multiple functions into a single device
2Ease of manufacture
If binary confirmation is used for remote control, then the control system is simple to implement, but it does not accurately reflect continuous driver control actions
Solution Approach 1:
The system transitions from static binary confirmation to dynamic continuous control. The mobile device application detects the device's tilt angle in real-time and converts it into corresponding pedal positions, allowing the driver to exercise continuous control over acceleration and braking with varying degrees of pressure
Solution Approach 2:
The system changes the control parameter from binary (confirmed/not confirmed) to continuous (tilt angle degree). The mobile device detects the tilt angle as a continuous variable and maps it to pedal position, enabling nuanced control where the driver can apply不同程度的 pressure equivalent to partial accelerator or brake pedal depression
3Speed
If the driver remains inside the vehicle to control it, then control response is immediate, but the driver cannot freely observe the vehicle from different positions
Solution Approach 1:
The mobile device application serves as a remote control intermediary that transmits control commands and receives feedback between the driver and vehicle. This allows the driver to operate the vehicle from any position within communication range while maintaining control response through the wireless connection
Solution Approach 2:
The system replaces the mechanical presence requirement (driver physically inside vehicle) with electronic communication (wireless signal transmission). The mobile device communicates with the vehicle control system via Bluetooth or other wireless protocols, substituting physical proximity with electronic connectivity

Function Achieved in This Case
This solution allows a single user to safely and precisely control a vehicle's movement without external assistance, improving safety and comfort by eliminating the need for a second person to navigate and reducing the risk of misunderstandings.
Implementation Method 1
a signal is received which represents a current tilt angle
Data Source
AI summary
A method for remotely controlling the movement of a vehicle by means of a hand-held device is described. The method includes the following steps: activating a button by pressing and holding the button by a user; setting a tilt angle of the device by the user starting from an initial tilt angle when activating the button; receiving a signal representing the current tilt angle of the device; converting the received signal into a virtual pedal position, which corresponds to the position of a physical pedal corresponding to the virtual pedal; controlling the movement of the vehicle according to the virtual pedal position; and stopping the vehicle if pressing and holding the button is ended.
