Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stop lamp lighting devices require a large number of component parts, leading to complex and time-consuming mounting processes.
Innovation Solution
A simplified configuration using a brake pedal sensor with a stop lamp switching section, brake position sensor section, and logic circuit section to generate control signals for controlling the lighting and blinking of the stop lamp, reducing the number of components and facilitating easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stop lamp lighting device is used with multiple separate components (lighting determination unit, stop lamp lighting control unit, vehicle speed sensor), then the device can detect abrupt brake pedal depressing and control stop lamp blinking, but the number of component parts increases causing long mounting time
Solution Approach 1:
The patent combines the lighting determination unit, stop lamp lighting control unit, and vehicle speed sensor into a single integrated brake pedal sensor assembly. The control unit is mounted on the brake pedal sensor housing and integrates multiple functions (speed detection, blinking determination, and stop lamp control) that were previously separate components, thereby reducing mounting time while maintaining the ability to detect abrupt brake pedal depression and control stop lamp blinking
2Adaptability or versatility
If conventional stop lamp lighting device is used with multiple separate components, then the device can perform speed-based blinking determination, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it detects vehicle speed via the sensor, determines whether to blink the stop lamp based on speed change rate, and controls the stop lamp output. This multi-functional integration reduces the number of separate components while maintaining the adaptability to perform speed-based blinking determination

AI summary
There are provided a brake pedal sensor and a stop lamp lighting device in a vehicle, which are capable of controlling blinking of a stop lamp in a simple configuration. The brake pedal sensor includes: a stop lamp switching section which outputs a switch signal; a brake position sensor section which outputs a brake position signal; and a logic circuit section for receiving the switch signal and a blinking signal generated by the brake position signal are inputted, and which outputs a control signal for controlling lighting and blinking of the stop lamp. Using this brake pedal sensor allows configuration of the stop lamp lighting device in a simpler manner.
