HMI Design for Autonomous Driving Mode Switching

This project designs the transition from Manual to Autonomous Driving mode in self-driving cars. It includes creating interactive elements for a seamless and intuitive handover from driver to vehicle control.

Design Task Brief——

Introduction of fully autonomous cars is no longer a distant reality. As we prepare to design for vehicles capable of self-driving, the moment of handover of control from human (driver) to computer (vehicle) will be of great importance. This exercise is going to design this transition moment from Manual Driving mode to Autonomous Driving mode in a car.

Background——

With the popularization of assisted driving functions such as L2 and L3, the mode switch between driver-controlled and vehicle-controlled driving has become an important vehicle control function.

Analysed Summary——

1. Safety
‍-Continuous monitoring and timely warnings under static/dynamic scenarios.
‍2. Trust Issues
‍-Drivers' trust issues with the autonomous driving system.
‍3. Operational Efficiency
‍-Simplify operational pathways through multiple channels, while preventing accidental entry into autonomous driving mode.
-Different scenarios can use different interaction methods.

Design Plan——

Autonomous Driving Mode

Status Breathing Light

The complexity of the situation is displayed through the status light, informing the driver of the driving status.

Seat Vibration Takeover Alert

When the driver needs to take over the steering wheel, pre-alert through seat vibration to warn the driver.Three Mode Switching Method.

Autonomous Switch Way

Voice Interaction

Enter voice command to switch to autonomous driving mode.

Mechanical Interaction

Pull the lever twice to enter autonomous driving mode.

Interface Interaction

Select "Autonomous Driving" on the central control panel.

Voice Interaction——

Convenience

Activate autonomous driving through simple voice commands without manual operation.

Safety

Allows the driver to activate autonomous driving while keeping both hands on the wheel, reducing distractions.

Error Prevention

Voice confirmation commands prevent accidental entry into autonomous driving mode.

Interface Design——

Precision

Mechanical controls typically provide accurate input, reducing the possibility of errors.

Intuitiveness

Physical buttons and switches offer more intuitive and easily understandable operations

Immediate Feedback

Immediate physical feedback confirms the user's actions.

Mechanical Interaction——

*Since ProtoPie cannot activate voice recognition interaction through voice command, when G-Va appears, you need to first click on G-Va. After clicking on G-Va, normal voice interaction can then proceed.

*The keyword to activate the autonomous driving mode is 'autonomous driving mode”
