EV Pseudo Shifting Control for Manual-Style Driver Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers who have not operated a manual transmission internal combustion engine vehicle for a long time or lack experience find it challenging to drive a battery electric vehicle that simulates manual transmission operations.
Innovation Solution
A battery electric vehicle equipped with an electric motor, pseudo shifting operation members, and a controller that allows drivers to select a control mode where pseudo shifting operations are associated with motor torque, with restrictions that can be eased or removed based on driver performance, and provides feedback and advice through an interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control mode simulating manual transmission operations is implemented in a battery electric vehicle, then drivers can experience manual transmission-like driving, but drivers without manual transmission experience find it difficult to operate
Solution Approach 1:
The system dynamically adjusts the degree of manual transmission simulation based on driver selection. The controller can switch between a first control mode with full manual transmission simulation characteristics and a second control mode with modified simulation characteristics, allowing the system to adapt its behavior to match driver skill level and preference.
Solution Approach 2:
The controller modifies operational parameters of the pseudo shifting operation member based on the selected control mode. In the first control mode, the pseudo shifting operation member operates with characteristics matching a real manual transmission shifter. In the second control mode, the operational parameters are adjusted to provide easier or modified operation, making it accessible to drivers without manual transmission experience.
2Adaptability or versatility
If pseudo shifting operation members are added to simulate manual transmission, then driving experience is enhanced, but device complexity increases
Solution Approach 1:
The pseudo shifting operation member serves multiple functions: it can operate as a traditional shifter in the first control mode providing authentic manual transmission simulation, and as a simplified control interface in the second control mode for drivers without experience. This multi-functionality allows a single device to cater to different driver needs without requiring separate physical shifters for each mode.
Solution Approach 2:
The system creates a virtual or simulated manual transmission control interface that copies the essential functionality of a real manual transmission shifter without requiring the complex mechanical linkage of an actual transmission system. The pseudo shifting operation member replicates the operational characteristics and feel of a manual shifter through electronic control, providing the desired driving experience with reduced mechanical complexity.

AI summary
A battery electric vehicle includes: a driving operation member configured to be used to drive the battery electric vehicle; and a pseudo shifting operation member that imitates an operation member configured to be used to perform a shifting operation of a manual transmission internal combustion engine vehicle. A controller that controls the battery electric vehicle is configured to execute, according to selection by a driver, a control mode in which an operation of the pseudo shifting operation member is associated with torque of the electric motor. The controller is further configured to impose, when in the control mode, a restriction on an operation the battery electric vehicle performs in response to the operation of the pseudo shifting operation member, the restriction being able to be removed or eased.
