Solution Overview

Problem

The inconsistency in signal transmission rates between the all-terrain control system and input systems in vehicles hinders effective terrain adaptation in all-terrain adaptive mode, leading to unsatisfactory compatibility and terrain adaptation effects.

Innovation Solution

A bidirectional transmission control system that includes a road surface recognition apparatus, a signal transfer apparatus, and an all-terrain controller, which recognizes the road surface type, sends terrain mode requests, and provides execution feedback to coordinate information transmission rates, enabling real-time switching between terrain modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the all-terrain control system operates with multiple control systems (engine control, ESP system) to achieve terrain adaptation, then the terrain adaptation capability is improved, but the signal transmission rate inconsistency between different systems reduces overall compatibility

Engineering Contradiction:
Improveterrain adaptation capabilityVSAvoidsignal transmission compatibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a signal transfer apparatus as an intermediary component between the road surface recognition apparatus and the all-terrain controller. This mediator converts and standardizes signals from different control systems (engine control, ESP system) into a unified format, enabling consistent communication and coordination across systems with different signal transmission rates, thereby resolving the compatibility issue while maintaining terrain adaptation capability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system integrates multiple control systems for comprehensive terrain control, then the terrain adaptation effect is improved, but the system complexity increases

Engineering Contradiction:
Improveterrain adaptation effectVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the signal transfer function into a dedicated apparatus that consolidates the coordination of multiple control systems (engine control, ESP system, road surface recognition). By combining these functions into a unified signal transfer apparatus, the system reduces overall complexity while maintaining comprehensive terrain control capability across all integrated systems

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If real-time terrain mode switching is implemented, then the driving performance is improved, but the information transmission rate inconsistency causes signal loss

Engineering Contradiction:
Improveterrain mode switching speedVSAvoidsignal loss
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the all-terrain controller sends execution information back through the signal transfer apparatus to confirm terrain mode activation. This bidirectional feedback loop ensures that real-time terrain mode switching is properly coordinated and confirmed, preventing signal loss by verifying that mode change commands are successfully transmitted and executed across all control systems

Inventive Principle:
Principle #23Feedback

AI summary

Disclosed is a bidirectional transmission control system for a vehicle. A road surface recognition apparatus collects an image of a road surface on which a vehicle drives currently, and forwards, after recognizing the type of the road surface on which the vehicle drives currently according to the image of the road surface, a corresponding first terrain mode request signal to an all-terrain controller through a signal transfer apparatus, so as to start a corresponding terrain mode in an all-terrain adaptive mode. In addition, the all-terrain controller forwards execution information about the terrain mode to the road surface recognition apparatus through the signal transfer apparatus, so as to implement state feedback of the terrain mode currently executed. The inconsistency of information transmission rates between an all-terrain control system of a vehicle and an input system can be coordinated, thereby aiding in real-time switching of various terrain modes.
