Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If regenerative braking force is excessively set, then fuel efficiency is improved, but driving feeling deteriorates and coasting cannot be utilized
Solution Approach 1:
The regenerative braking level is dynamically adjusted based on real-time driving conditions including vehicle speed, acceleration, road gradient, and traffic状况. The system transitions from static manual setting to dynamic automatic control, optimizing the braking force at different driving phases to balance energy recovery and driving comfort
Solution Approach 2:
The system continuously monitors driver behavior patterns, vehicle state, and road conditions, then feeds this information back to adjust the regenerative braking level. The control unit learns from driver preferences and automatically modifies braking intensity to match both energy efficiency goals and driver expectations
2Ease of operation
If regenerative braking level is set to be low, then driving feeling is improved, but driving fatigue increases due to frequent brake pedal operation
Solution Approach 1:
The system performs self-adjustment of regenerative braking levels based on learned driver behavior patterns and current driving conditions. The control unit automatically manages brake pedal operations by coordinating regenerative braking with friction braking, reducing the need for frequent manual brake interventions while maintaining driver comfort
3Device complexity
If driver manually sets regenerative braking level, then system simplicity is maintained, but fuel efficiency is reduced due to inability to adapt to road conditions
Solution Approach 1:
A server acts as an intermediary between the driver and the regenerative braking control system. The server receives driving information, analyzes road conditions, and transmits optimized control values to the vehicle's control unit, enabling intelligent adaptation without requiring complex driver input or system redesign
Solution Approach 2:
The system dynamically changes multiple parameters including regenerative braking level, motor torque, and battery charging rate based on real-time conditions. The server processes driving information and transmits adjusted control parameters to optimize energy recovery while adapting to varying road gradients, traffic conditions, and driver behavior patterns

AI summary
A server and a method for automatically controlling regenerative braking of an eco-friendly vehicle are provided. A regenerative braking level is calculated by considering driving information and a driving environment of a vehicle using a regenerative braking controlling server. The calculated regenerative braking level is transmitted to a regenerative braking controlling apparatus mounted within the vehicle and thus, even though a vehicle driver does not directly set the regenerative braking level, the regenerative braking level transmitted from the regenerative braking controlling server is received through the regenerative braking controlling apparatus of the vehicle to perform regenerative braking, thereby enhancing driving convenience and stability, and fuel efficiency.
