Vehicle One-Pedal Control Device with Seatbelt Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The one-pedal function in vehicles may allow the vehicle to start moving if the driver detaches their seatbelt during travel, as the braking force weakens when the driver is absent, potentially leading to unsafe situations.
Innovation Solution
A control device is implemented that includes a traveling control unit for managing both driving and braking forces via the accelerator pedal and an output control unit that notifies the driver to depress the brake pedal if the seatbelt is detached during one-pedal function operation and the vehicle stops, ensuring the vehicle remains stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the one-pedal function is used to control driving and braking forces, then the ease of operation is improved, but the reliability deteriorates when the driver detaches the seatbelt and the vehicle stops
Solution Approach 1:
The control device continuously monitors seatbelt attachment status and provides feedback to the driver through notifications. When the seatbelt is detached during one-pedal function operation and the vehicle stops, the system notifies the driver to depress the brake pedal, creating a closed-loop feedback mechanism that maintains reliability without compromising ease of operation
Solution Approach 2:
The system performs preliminary detection of seatbelt status and vehicle stop conditions before the reliability issue manifests. By notifying the driver in advance when the seatbelt is detached and the vehicle stops, the system prevents potential safety issues before they occur, maintaining both ease of operation and reliability

AI summary
A control device configured to control a vehicle is provided. The device comprises a traveling control unit capable of executing a one-pedal function of controlling both a driving force and a braking force of the vehicle in accordance with an operation amount of an accelerator pedal, and an output control unit of notifying a driver of an instruction to depress a brake pedal in a case in which a seatbelt is detached during execution of the one-pedal function and during traveling of the vehicle, and the vehicle stops in that state.
