Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control methods for boost mode in vehicles conservatively manage durable time to prevent drivetrain damage, limiting the use of boost driving and thus restricting the vehicle's acceleration performance and commercial value.
Innovation Solution
A control method that dynamically adjusts the durable boost time based on real-time drivetrain state information and driver input, allowing for variable management of boost mode usage and displaying the remaining boost time to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the durable time of boost mode is conservatively managed to prevent drivetrain damage, then the reliability of the drivetrain is improved, but the acceleration performance and commercial value of the vehicle deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of the durable boost time based on real-time drivetrain state information. The controller continuously monitors drivetrain conditions and modifies the allowable boost duration accordingly, transitioning from a static conservative limit to a dynamic adaptive parameter that optimizes both reliability and performance
Solution Approach 2:
The patent changes the parameter of durable boost time from a fixed conservative value to a variable parameter that adjusts based on drivetrain state. By monitoring real-time conditions and modifying the time parameter dynamically, the system resolves the contradiction between maintaining reliability and achieving acceleration performance
2Device complexity
If the durable time of boost mode is limited to a predetermined single condition, then the simplicity of control is improved, but the acceleration performance and commercial productivity of the vehicle deteriorate
Solution Approach 1:
The patent introduces feedback mechanisms where the controller receives real-time drivetrain state information and uses this feedback to adjust the durable boost time. This closed-loop control approach enables sophisticated performance optimization without requiring overly complex control logic, as the system adapts automatically based on sensor data
3Productivity
If the durable time of boost mode is extended beyond conservative limits, then the acceleration performance is improved, but the risk of drivetrain damage increases
Solution Approach 1:
The patent applies beforehand cushioning by continuously monitoring drivetrain state information before allowing boost mode operation. The system prepares protective measures by assessing current drivetrain conditions and adjusting the durable boost time limit in advance, preventing damage while maximizing usable boost time

AI summary
A control method for a boost of a vehicle for increasing a boost mode use time by a driver and being able to maximize the acceleration performance and commercial value of a vehicle, includes entering, by a controller, the boost mode so that boost-driving is performed when there is input of boost mode-on by a user, obtaining, by the controller, real-time driving state variable information while the vehicle is driven in the boost mode, increasing or decreasing, by the controller, a durable boost time in accordance with the obtained real-time driving state variable information, and displaying, by the controller, the boost standby time which is changed, on a display device of the vehicle.
