Universal Automotive Pedal Device with Rotating Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separate production of manually controlled and electronically controlled pedal devices for automotive vehicles is costly and time-consuming, as they require distinct designs and components, increasing overall production costs and throughput.
Innovation Solution
A common use pedal device with a base plate, pivotably attached pedal, rotating member, and rotation detecting sensor, which allows for adjustable rotation stroke and electric signal generation, enabling compatibility with both manually controlled and electronically controlled vehicles through a stroke adjustor and slip-proof mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate pedal devices are produced for manual and electronic control systems, then each device can be optimized for its specific function, but production costs and manufacturing time increase significantly
Solution Approach 1:
The pedal device is designed with dual functionality to work with both manual cable-operated systems and electronic sensor-based systems. The rotating member can operate in two modes: mechanically pulling a cable for manual control, or rotating a detection sensor for electronic control. This universal design allows a single pedal device to replace two separate designs, thereby improving production efficiency while maintaining functional optimization for each control type.
2Productivity
If a common pedal device is used for both manual and electronic control systems, then production costs and manufacturing time are reduced, but the device must accommodate multiple control mechanisms which increases structural complexity
Solution Approach 1:
The pedal device is segmented into distinct functional modules: the pedal body, the rotating member, the cable pulling mechanism, and the detection sensor mounting structure. Each module can be independently configured or removed based on whether manual or electronic control is required. This segmentation allows the common device to accommodate multiple control mechanisms while keeping the overall structure manageable and not excessively complex.
3Device complexity
If the pedal rotation stroke is fixed, then the device structure is simpler, but it cannot adapt to different vehicle types and control requirements
Solution Approach 1:
The pedal device incorporates an adjustable stroke mechanism that allows the rotation stroke of the pedal to be dynamically changed. A stroke adjustor means is provided that can modify the position of the stopper, thereby adjusting the rotation stroke of the pedal and the pulling amount of the cable or the rotation angle of the detection sensor. This dynamic adjustability enables the same pedal device to adapt to different vehicle types and control requirements without increasing overall structural complexity.

AI summary
A common use pedal device for automotive vehicles comprises a base plate and a pedal pivotably attached to the base plate and having a push rod extending downwards from an underneath surface of the pedal. A rotating member is mounted to the base plate in such a manner that the rotating member can be depressed and rotated by the push rod of the pedal, the rotating member having a pulling arm adapted to pull a manual operating cable in response to rotation of the rotating member. A rotation detecting sensor is provided on one side of the base plate for detecting the degree of rotation of the rotating member and then notifying an electronic control unit of the degree of rotation thus detected. This pedal device can be employed in common in a manually controlled pedal type vehicle and an electronically controlled pedal type vehicle.
