Vehicle Sensor Signal Processing for Multi-Band Controller Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems require multiple sensors to be mounted on vehicles, as different controllers use signals from different frequency bands, leading to an increase in the number of sensors needed.
Innovation Solution
A processor that acquires sensor signals from a single sensor, processes them using multiple filters to extract different frequency bands, and outputs these signals simultaneously to various controllers, reducing the need for multiple sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are provided for each controller to handle different frequency bands, then each controller can use the appropriate frequency band, but the number of mounted sensors increases
Solution Approach 1:
The single sensor device is designed to serve multiple controllers with different frequency band requirements. The sensor device includes a processor that can generate multiple output signals with different frequency characteristics from a single sensor input, making the sensor universal for multiple control applications.
Solution Approach 2:
The processor segments the sensor signal into multiple frequency bands using different filters (low-pass filter, band-pass filter, high-pass filter). This segmentation allows each controller to receive the specific frequency band it needs while sharing the same physical sensor.
2Quantity of substance
If a single sensor is used for multiple controllers, then the number of mounted sensors is reduced, but different frequency bands need to be extracted for different controllers
Solution Approach 1:
The processor acts as an intermediary between the single sensor and multiple controllers. It receives the raw sensor signal, processes it through various filters to create different frequency band outputs, and then distributes these processed signals to the appropriate controllers.
Solution Approach 2:
The processor changes the frequency parameters of the sensor signal by applying different filter characteristics (low-pass, band-pass, high-pass). This allows the same physical signal to be transformed into multiple versions with different frequency properties for different control applications.

AI summary
The present invention provides a processor, a sensor device, a control system, and a processing method capable of suppressing an increase in the number of mounted sensors. A processor 132 is a processor 132 that processes a sensor signal output from a sensor mounted to a vehicle, and includes: an acquisition section 132a that acquires the sensor signal output from the sensor; a first processing section 132b that generates first output signals through first filters F11, F12, F13, F14, F15, F16, each of which extracts a first frequency band from the sensor signal acquired by the acquisition section 132a; a second processing section 132c that generates second output signals through second filters F21, F22, F23, F24, F25, F26, each of which extracts a second frequency band, which differs from the first frequency band, from the sensor signal acquired by the acquisition section 132a; and an output section 132d that outputs the first output signal and the second output signal at once.
