| 研究実績の概要 |
Our research focuses on modeling lane change behavior of individual driver and designing a guidance-as-needed steering system through haptic interface.
In FY 2019, our research achievements are summarized as follows:
1. A discrete lane change model based on gap acceptance was developed through a driving simulator experiment with a number of subjects.
2. A deep reinforcement learning based haptic guidance algorithm was developed and its effectiveness on individual driver steering assistance was verified by numerical simulations.
3. A driving simulator experiment with a number of subjects was conducted to evaluate a proposed intention-based haptic guidance system for lane change tasks. The results demonstrate that the designed system is adaptive and capable to improve driving safety and comfort.

理由
1. A driving simulator experiment with a number of participants was conducted to collect the driving data, which are used to analyze the driver behavior, and a discrete lane change model based on gap acceptance was developed.
2. By real-time measuring driver eye movement, an intention-based haptic guidance system was designed to assist individual drivers for lane change tasks. The results from a driving simulator experiment with a number of participants demonstrate that the system is adaptive and capable to improve driving safety and comfort.
3. A driving simulator experiment with more complex traffic situation for a merging task has been designed and will be conducted in the next fiscal year. The haptic guidance system was implemented in an electric car for future real-vehicle experiments.

| 今後の研究の推進方策 |
In the next fiscal year, our research activities will focus on the following aspects:
1. The designed guidance-as-needed steering system will be evaluated in a more complex traffic situation by driving simulator experiments.
2. Real vehicle experiments will be conducted to evaluate the the effectiveness of guidance-as-needed steering system on lane change performance and driver acceptance.
3. The driver behavior measrued in the driving simulator and real-vehicle experiments will be analyzed for better understanding of driver's integration of visual and haptic information during a lane change task.

| 次年度使用額が生じた理由 |
In this fiscal year, we have focused on driver model development, numerical simulation, and driving simulator experiments. Thus, we purchased experimental equipment, hired research assistant for data analysis and recruited subjects for the experiments. Meanwhile, we used relatively less money for the travel. In the next fiscal year, we will conduct driving simulator and real vehicle experiments by recruiting subjects, and will spend travel expense to present the findings.
