Electronic Throttle Deviation Compensation for Leisure Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic control throttle systems in leisure vehicles experience deviations between rider input and throttle valve position, leading to reduced responsiveness, especially at low engine speeds, affecting the rider's control experience.
Innovation Solution
An engine with an electronic control throttle system that includes a first throttle position sensor and a detection device to detect predetermined positions of the throttle valve, allowing the controller to calculate and compensate for deviations by adjusting the drive signal, thereby improving responsiveness to rider operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an electronic control throttle system is used, then control precision and responsiveness are improved, but deviation between rider input and throttle valve position occurs causing reduced responsiveness
Solution Approach 1:
The system uses a detection device to detect the actual throttle valve position and feeds this information back to the controller. The controller compares the detected position with the target position and generates a deviation signal to adjust the drive signal, creating a closed-loop feedback control system that eliminates positioning errors and improves rider control responsiveness.
Solution Approach 2:
The system performs preliminary detection of the throttle valve position using the detection device before final positioning. By detecting the actual position in advance and calculating the deviation, the system can pre-adjust the drive signal to compensate for potential positioning errors, ensuring accurate throttle valve positioning that responds immediately to rider input.
2Extent of automation
If an electronic control throttle system is used, then automation is improved, but deviation compensation is needed to maintain responsiveness
Solution Approach 1:
The detection device continuously monitors the throttle valve position and provides feedback to the controller. This feedback mechanism ensures that automated control deviations are detected and corrected in real-time, maintaining reliable responsiveness throughout automated operation without requiring manual intervention.
Solution Approach 2:
The system performs self-correction by automatically detecting position deviations and adjusting the drive signal without external intervention. The controller autonomously compensates for positioning errors, making the electronic control system self-correcting and maintaining high reliability of control responsiveness throughout automated operation.

AI summary
An engine for a leisure vehicle equipped with an electronic control throttle system configured to operate an actuator based on a drive signal sent from a controller to the actuator in response to a rider's operation of a throttle operation device to cause a throttle valve of an air-intake device to open or close, including a first throttle position sensor configured to detect a movement position of the throttle valve; and a detection device configured to detect at least a predetermined position in an open state or a closed state of the throttle valve; wherein the controller determines a deviation between the predetermined position and the movement position of the throttle valve, compensates for a deviation by adjusting the drive signal based on a deviation if the deviation is above a preset value, and sends the adjusted drive signal to the actuator to cause the throttle valve to open or close.
