ATV Motion Control for Backward Roll and Airborne Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-terrain vehicles face challenges in controlling operation during rough terrain conditions, such as unintended rolling backwards or becoming airborne, which can lead to damage and loss of control, necessitating advanced systems for stabilization and safety.
Innovation Solution
The integration of a controller system in all-terrain vehicles that utilizes a combination of sensors, including GPS, accelerometers, wheel speed sensors, and throttle sensors, to determine the vehicle's orientation and movement, activating the backup camera and engaging electronic stability control (ESC) or anti-lock braking systems (ABS) as needed, while also managing driveline configurations and brake modes to maintain stability.

Engineering Contradiction Analysis
1Reliability
If the all-terrain vehicle operates in rough terrain without advanced control systems, then the vehicle structure remains simple, but the vehicle may unintentionally roll backwards or become airborne leading to damage and loss of control
Solution Approach 1:
The controller proactively determines vehicle orientation and movement state before actual backward rolling or airborne events occur. By using sensors (accelerometers, GPS, wheel speed sensors) to detect early signs of unstable conditions and preemptively activating safety features like backup camera and stability control, the system prevents damage before it happens rather than reacting after the fact.
Solution Approach 2:
The system continuously monitors vehicle state through multiple sensors (accelerometers, GPS receivers, wheel speed sensors, throttle sensors) and feeds this information back to the controller. The controller adjusts control modes based on real-time feedback about vehicle orientation, speed, and terrain conditions, enabling dynamic adaptation to rough terrain while maintaining stability.
2Reliability
If the controller activates backup camera and stability control systems continuously, then vehicle safety is maximized, but energy consumption increases
Solution Approach 1:
The control system dynamically adjusts its operation based on real-time vehicle conditions rather than running continuously at full capacity. The controller activates specific safety features (backup camera, ESC, ABS) only when needed based on detected conditions such as backward movement, steep slopes, or unstable terrain, thereby maintaining safety while reducing unnecessary energy consumption during normal operation.
Solution Approach 2:
The system changes operational parameters (which safety features are active) based on detected vehicle state parameters. When sensors detect conditions indicating potential danger (backward rolling, airborne state, steep incline), the controller changes the state of safety systems from inactive to active, optimizing the balance between safety and energy usage.
3Measurement precision
If the vehicle uses multiple sensors and control modes to detect backward movement, then detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (accelerometers, GPS receivers, wheel speed sensors, throttle sensors) into an integrated control system that processes information from all sources together. By merging these sensor inputs, the system achieves high detection accuracy for backward movement and vehicle state through data fusion, where the combined information from multiple sensors provides more reliable detection than any single sensor alone.
Solution Approach 2:
The controller serves multiple functions using the same sensor inputs: it determines vehicle orientation, detects backward movement, identifies airborne states, and controls multiple safety features (backup camera, ESC, ABS). This multi-functionality reduces the need for separate dedicated sensors for each function, optimizing the balance between detection precision and system complexity.

AI summary
An all-terrain vehicle may include a frame and a plurality of ground-engaging members supporting the frame. The all-terrain vehicle may further include a powertrain assembly supported by the frame and shiftable transmission supported by the frame and operably coupled to the powertrain assembly. The all-terrain vehicle may also include a display, a back-up camera, and a controller supported by the frame. The controller may be configured to receive a signal from the shiftable transmission corresponding to the shiftable transmission being in a gear of the plurality of gears other than a reverse gear. Further, the controller may be configured to determine the all-terrain vehicle is moving backwards and send an activation signal to the back-up camera to display images of the back-up camera on the display.
