Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine power suppressing devices experience non-uniformity in the amount of power suppressed due to varying use environments, leading to inconsistent engine power delivery and prolonged or inadequate suppression of wheelie and slip conditions.
Innovation Solution
An engine power suppressing device equipped with a controller and environment sensors that adjust the suppressing value based on detected environment parameters, such as atmospheric pressure, to compensate for non-uniformities, ensuring consistent engine power suppression across different environments and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed suppressing value is used for the power changing element, then the device complexity is reduced, but non-uniformity of engine power suppression occurs due to varying use environments
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed suppressing value to a dynamic suppressing value that changes based on detected environment parameters. The controller adjusts the suppressing value in real-time according to atmospheric pressure, temperature, and altitude conditions, making the control system adaptive to varying use environments and eliminating non-uniformity in engine power suppression.
Solution Approach 2:
The patent implements parameter changes by modifying the suppressing value parameter based on environment parameters detected by sensors. The controller calculates appropriate suppressing values by considering atmospheric pressure, temperature, and altitude variations, thereby maintaining consistent engine power suppression across different environmental conditions without requiring overly complex system architecture.
2Reliability
If environment sensors and dynamic compensation are added to the controller, then non-uniformity of engine power suppression is reduced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the controller to perform multiple functions: it not only controls the power changing element but also detects environment parameters, calculates appropriate suppressing values, and compensates for environmental variations. This multi-functional approach consolidates complexity into a single control unit rather than requiring separate dedicated systems for each function.
Solution Approach 2:
The patent implements feedback by using environment sensors to continuously monitor atmospheric conditions and feeding this information back to the controller. The controller then adjusts the suppressing value based on this feedback, creating a closed-loop system that automatically compensates for environmental variations and maintains consistent engine power suppression without manual intervention.
3Reliability
If the suppressing value is adjusted based on atmospheric pressure, then engine power suppression consistency is improved, but the time required to terminate slip or wheelie states may be extended
Solution Approach 1:
The patent applies dynamics by implementing a dynamic response mechanism where the controller continuously monitors both environment parameters and vehicle state parameters. When slip or wheelie conditions are detected, the system can rapidly adjust the suppressing value beyond just environmental compensation, ensuring quick termination of unstable states while maintaining uniform suppression under normal operating conditions.

AI summary
An engine power suppressing device includes a controller which controls an operation of a power changing element which changes engine power for driving a vehicle; and an environment sensor which detects an environment parameter indicating an environment in which the vehicle is used, wherein the controller determines whether or not a power suppressing condition in which a vehicle state is a state in which the engine power is to be suppressed, is met, wherein in a case where the controller determines that the power suppressing condition is met, the controller sets a suppressing value for the power changing element to suppress the engine power, and compensates the suppressing value based on the environment parameter detected by the environment sensor.
