The behavior of driver is formed by recognition, decision and operation. Driver has to grasp parameters such as changing of environments and movements of the automobile. There are chances that vehicle movements might be drivers' mental-workload and cause them to make mistakes in judgment and to disturb their operation of the car. In this report, we measured drivers' psychological reaction, and vehicle movements such as velocity, acceleration, and steering angle through the test. In order to consider time-series factors of psychological reaction, we used Wavelet Analysis from R-R interval of heart beat variability to clarify activities of autonomic nerve. As a result, we could specify the parameters of vehicle movements, which cause drivers' mental-workload. In addition, we could make a specific group of drivers who easily get the mental-workload from vehicle movements by using HQL Workload Sensitivity Questionnaire on drivers' individual characteristics.
