Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the durable time of boost mode is conservatively set to prevent drivetrain damage, then the reliability of the drivetrain is improved, but the acceleration performance and productivity of the vehicle deteriorates
Solution Approach 1:
The patent implements dynamic management of boost standby time based on real-time drivetrain state information. The controller adjusts the standby time period variable according to current drivetrain conditions, transitioning from a static conservative approach to a dynamic adaptive approach. This allows the system to optimize between durability protection and performance maximization in real-time, resolving the contradiction by making the durable time adaptive rather than fixed.
Solution Approach 2:
The patent changes the parameter of boost standby time from a fixed conservative value to a variable that is adjusted based on drivetrain state information. By monitoring real-time conditions and modifying the standby time parameter accordingly, the system achieves both drivetrain protection and improved acceleration performance, resolving the contradiction through parameter optimization.
2Reliability
If the boost standby time is extended to ensure drivetrain protection, then the reliability is improved, but the loss of time for boost usage increases
Solution Approach 1:
The patent optimizes the standby time parameter by adjusting it based on real-time drivetrain state information. Instead of using a fixed extended standby time, the system dynamically modifies this parameter to achieve the minimum necessary protection period, thereby reducing time loss while maintaining drivetrain protection.
Solution Approach 2:
The system monitors its own drivetrain state and autonomously adjusts the standby time parameter accordingly. This self-regulating mechanism ensures that the standby time is neither excessively long nor insufficient, optimizing both protection and time efficiency without external intervention.
3Reliability
If the boost mode is restricted to conservatively managed durable time, then the reliability of drivetrain is improved, but the commercial value and ease of operation deteriorates
Solution Approach 1:
The patent makes the boost mode operation dynamic by allowing real-time adjustment of standby time based on drivetrain state. This transforms the conservative restricted approach into an adaptive system that provides both protection and operational flexibility, improving ease of use while maintaining reliability.
Solution Approach 2:
The system implements feedback by continuously monitoring drivetrain state information and using it to adjust the standby time parameter. This closed-loop control ensures that boost usage remains within safe limits while maximizing operational flexibility and commercial value.

AI summary
A control method for a boost mode of a vehicle includes entering, by a controller a boost mode so that boost-driving may be performed when there is input of boost mode-on from a user, obtaining, by the controller, real-time driving state variable information while a vehicle is driven with the boost mode entered, increasing or decreasing, by the controller, a boost standby time in accordance with the obtained real-time driving state information, displaying, by the controller, the boost standby time thus changed on a display device of the vehicle when the boost mode is turned off, and displaying, by the controller, the boost standby time while decreasing the boost standby time displayed on the display device over time.
