E-bike Electronic Controller Dynamic Assist Mode Adjustment

The patent implements dynamic adjustment of assist modes based on real-time traveling conditions. The electronic controller monitors conditions such as human driving force, vehicle speed, acceleration, and terrain slope, then automatically switches between multiple assist modes (e.g., eco mode, standard mode, sport mode) to optimize assistance levels. This dynamic adaptation resolves the contradiction by making the control system responsive to changing conditions, thereby improving traveling comfort without requiring overly complex manual intervention from the user.

The control system incorporates feedback mechanisms that continuously monitor traveling conditions and adjust assist modes accordingly. Sensors detect parameters like pedaling force, vehicle speed, and acceleration, feeding this information back to the electronic controller which then selects appropriate assist modes. This feedback loop enables automatic optimization of assist levels based on actual traveling needs, improving comfort while maintaining reasonable system complexity through automated decision-making.

The patent employs parameter changes by adjusting assist levels dynamically based on traveling conditions. Different assist modes correspond to different parameter settings for motor assistance. For example, in eco mode the assist level is reduced to conserve energy, while in sport mode the assist level is increased for better performance. The electronic controller selectively applies these parameter changes based on detected conditions such as terrain slope, vehicle speed, and human driving force, thereby optimizing the balance between comfort and energy consumption.

The system dynamically adjusts assist levels rather than maintaining a fixed high assistance level. By monitoring traveling conditions in real-time and switching between different assist modes, the system provides high assistance only when necessary (e.g., during uphill climbing or acceleration phases) and reduces assistance during normal cruising conditions. This dynamic approach maintains traveling comfort when needed while significantly reducing overall energy consumption compared to continuously high assist levels.

The control system incorporates preliminary actions by setting threshold conditions and delay mechanisms before switching assist modes. When a condition change is detected, the system evaluates whether the change is significant and sustained before initiating mode switching. This preliminary evaluation prevents premature or unnecessary mode changes, ensuring that assist mode transitions occur only when genuinely warranted by traveling conditions. This approach maintains adaptability to real conditions while preserving control stability by avoiding erratic switching.

The system employs beforehand cushioning through hysteresis bands and minimum duration requirements for mode switching. When transitioning between assist modes, the system incorporates buffer zones that prevent immediate reverse switching, and requires conditions to be met for a minimum time period before mode changes take effect. This cushioning mechanism smooths out transient fluctuations in traveling conditions, allowing the system to adapt to genuine changes while maintaining stability by filtering out noise and temporary variations.
