Solution Overview

Problem

Existing vehicle control systems require multiple conversion sections for non-acceleration control requests, leading to inefficiencies in design and increased complexity when handling multiple control requests for position, speed, and acceleration.

Innovation Solution

A control request arbitration apparatus that integrates position, speed, and acceleration control request arbitration and conversion sections, eliminating the need for separate conversion sections in each non-acceleration control request apparatus by deriving a single acceleration request from multiple input requests and converting it into a torque control request, while ensuring the request falls within achievable limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate conversion sections are provided in each non-acceleration control request apparatus, then each apparatus can independently convert its control requests, but the number of conversion sections increases and design efficiency decreases

Engineering Contradiction:

Improveindependent conversion capabilityVSAvoidnumber of conversion sections

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the conversion functions of multiple non-acceleration control request apparatuses into a single shared conversion section. Instead of each apparatus having its own conversion section, they all utilize the same conversion resources, thereby reducing the total number of conversion sections while maintaining the ability to handle multiple control requests independently through the arbitration apparatus.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The conversion section is designed to be universal and multi-functional, capable of converting control requests from any non-acceleration control request apparatus. This single conversion section serves multiple purposes and multiple apparatuses, eliminating the need for dedicated conversion sections for each apparatus while preserving full conversion capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple conversion sections are provided for different non-acceleration control requests, then all control requests can be processed, but the system complexity and design difficulty increase

Engineering Contradiction:

Improvehandling multiple control request typesVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conversion section is designed as a universal component that can handle conversion for all types of non-acceleration control requests (position, speed, etc.) through a unified interface and processing logic, eliminating the need for multiple specialized conversion sections while maintaining full adaptability to different request types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The arbitration apparatus acts as an intermediary between multiple non-acceleration control request apparatuses and the single conversion section. It manages and coordinates the conversion requests, ensuring that the universal conversion section can efficiently process different types of control requests without requiring complex individual processing paths for each type.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If separate conversion sections are used in each control request apparatus, then conversion can be performed locally, but the overall control response speed decreases

Engineering Contradiction:

Improvelocal conversion capabilityVSAvoidcontrol response speed

Core Design Contradiction:

Ease of operationVSSpeed

Solution Approach 1:

By merging conversion functions into a single shared conversion section, the system eliminates redundant conversion operations that would occur if each apparatus performed its own conversion. The arbitration apparatus efficiently manages the conversion process, reducing overall processing time and improving control response speed while maintaining the functional equivalence of local conversion.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A control request arbitration apparatus of a vehicle includes respective sections for selecting one of a plurality of position control requests generated by control request apparatuses, for converting the selected position control request to a converted speed control request, for selecting one of a plurality of speed control requests including the converted speed control request, for converting the selected speed control request to a converted acceleration control request, and for selecting one of a plurality of acceleration control requests including the converted acceleration control request. Since position/acceleration and speed/acceleration conversion sections become unnecessary in control request apparatuses, the total of these sections becomes independent of the number of control request apparatuses.
