Solution Overview

Problem

It is complex for drivers, especially inexperienced ones, to configure vehicles with multiple sub-systems to suit specific driving scenarios, such as off-road conditions, due to the numerous attributes like surface type, conditions, and topology that need to be considered.

Innovation Solution

A system with a user interface that allows drivers to input attributes of a driving scenario, using a GUI with controls for surface type, conditions, topology, and vehicle orientation, which processes this information to determine the optimal configuration for vehicle sub-systems like throttle and suspension, and communicates this configuration to the sub-systems for operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a driver manually configures multiple vehicle sub-systems for different driving scenarios, then the vehicle can be adapted to specific conditions, but the complexity and difficulty of configuration increases significantly

Engineering Contradiction:
Improvevehicle configuration adaptabilityVSAvoidconfiguration ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects driving scenario attributes (surface type, conditions, topology, vehicle orientation) and autonomously determines the optimal configuration for multiple vehicle sub-systems without requiring manual driver input for each parameter

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A single user interface system performs multiple functions: it detects various driving scenario attributes, processes this information, determines configurations for different sub-systems (suspension, throttle, steering), and provides driving advice, replacing multiple separate configuration tasks

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If a system provides detailed configuration options for multiple sub-systems, then the precision of configuration determination improves, but the device complexity increases

Engineering Contradiction:
Improveconfiguration determination precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system combines multiple configuration determination functions for different sub-systems (suspension, throttle, steering, brakes) into a single integrated processing unit that receives scenario attributes and outputs coordinated configurations for all sub-systems simultaneously

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A central processing system acts as an intermediary between the user interface and multiple vehicle sub-systems, translating high-level driving scenario descriptions into specific configuration parameters for each sub-system without exposing the complexity of individual sub-system configurations to the driver

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a system and method for controlling at least one vehicle subsystem, in particular in off-road mode. The driver enters a plurality of attributes, e.g. surface material, wetness and bounciness, possibly inclination, via a user interface. A processor determines the appropriate configuration based on the input.
