Hybrid Vehicle Driving Mode Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hybrid vehicle systems require manual driver input to change driving modes, making it inconvenient to adapt to changing driving conditions.
Innovation Solution
A vehicle equipped with a sensing device to acquire driving information and a controller that automatically determines and adjusts the driving mode by controlling the engine, motor, powertrain, and transmission based on road and traffic conditions, allowing seamless transitions between different driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual driver input is required to change driving modes, then the driver has direct control over driving mode selection, but the convenience and adaptability to changing driving conditions deteriorates
Solution Approach 1:
The vehicle system automatically monitors driving conditions through sensing devices and autonomously determines optimal driving modes without requiring manual driver input. The controller self-adjusts driving modes based on real-time data from sensors detecting road conditions, traffic状况, and vehicle performance parameters
Solution Approach 2:
The system continuously collects feedback from sensing devices about driving conditions and uses this information to dynamically adjust driving modes. The controller processes sensor data and makes real-time decisions to switch between driving modes, creating a closed-loop control system that adapts to changing conditions
2Adaptability or versatility
If the driver manually selects driving modes, then the system complexity remains low, but the adaptability to diverse driving conditions deteriorates
Solution Approach 1:
The controller serves multiple functions by integrating driving mode selection, performance optimization, and coordination of powertrain components. A single control unit handles various driving modes (economic, sport, normal) and automatically adjusts engine, motor, and transmission parameters across different operating conditions
Solution Approach 2:
The system combines multiple sensing devices (road condition sensors, traffic sensors, vehicle performance sensors) and integrates their data into a unified control system. The controller merges information from various sources to make comprehensive driving mode decisions, coordinating engine, motor, and transmission operations simultaneously
3Productivity
If automatic driving mode change is implemented, then the fuel efficiency and performance are optimized, but the loss of driver control deteriorates
Solution Approach 1:
The system provides dynamic driving mode adjustment that adapts to real-time driving conditions while allowing driver input. The controller can automatically switch between economic, sport, and normal modes based on sensed conditions, but the driver retains the ability to manually select preferred modes or override automatic decisions

AI summary
A vehicle can include: a sensing device configured to acquire driving information of the vehicle; and a controller configured to determine whether a current driving mode of the vehicle is changeable based on the driving information, to identify a driving mode among a plurality of driving modes which corresponds to the driving information upon determining that the current driving mode is changeable, and to control an operation of the vehicle so as to change the current driving mode to the identified driving mode.
