Hybrid Vehicle Route Section Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid vehicle control systems cannot precisely tailor driving patterns to driver preferences, limiting driver involvement in fuel-efficient driving and awareness.
Innovation Solution
A vehicle control device and method that allows drivers to set and customize driving modes, including HV and EV modes, by dividing routes into sections and associating each section with a specific driving mode, enabling operators to change modes and boundary points based on their preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the operating schedule for each section is automatically set by the system, then fuel consumption is minimized through optimized engine and motor scheduling, but the driving pattern cannot be precisely tailored to the driver's preferences
Solution Approach 1:
The driving route is divided into multiple sections, and the operating schedule is segmented into different patterns (fuel-efficient pattern, normal pattern, power priority pattern) that can be independently selected for each section. This allows drivers to customize the driving pattern for each section while the system maintains optimized engine and motor scheduling for fuel consumption reduction.
Solution Approach 2:
The system dynamically allows drivers to change the operating schedule pattern for each section before departure, making the previously fixed automatic scheduling adaptable to driver preferences. The pattern selection is flexible and can be modified without restricting the optimized fuel consumption benefits.
2Use of energy by moving object
If the system automatically sets the operating schedule to minimize fuel consumption, then fuel efficiency is improved, but driver involvement and awareness of fuel-efficient driving is reduced
Solution Approach 1:
The system provides drivers with the ability to select and customize operating schedules for different route sections, creating active involvement and awareness. This feedback mechanism allows drivers to understand and control fuel-efficient driving patterns while maintaining the optimized fuel consumption benefits of automatic scheduling.
3Adaptability or versatility
If multiple driving modes are provided with customizable sections, then driving patterns can be precisely tailored to driver preferences, but the device complexity increases
Solution Approach 1:
The control device integrates multiple functions into a single system: route division into sections, provision of multiple operating schedule patterns (fuel-efficient, normal, power priority), and customizable pattern selection for each section. This multi-functional integration allows precise driving pattern customization without proportionally increasing device complexity, as one control system handles all these functions.

AI summary
A vehicle control method having an HV driving mode in which operation of an internal combustion engine is permitted and an EV driving mode in which a vehicle is driven by using a motor with the internal combustion engine stopped includes the steps of: setting a destination; setting a driving route from a starting point to the destination; dividing the driving route and associating any of the driving modes with each section of the divided driving route; fixing the division of the driving route and the driving mode associated with each section based on an instruction from an operator; and causing the vehicle to travel each section in the associated driving mode.
