Motion Sickness Dose Value (MSDV)
运动病剂量值，ISO 2631 标准定义的基于「频率加权加速度」的晕动症预测指标，低于 1 Hz 的频率被放大以匹配人体敏感区间。
English Definition
"A frequency-weighted acceleration metric defined in ISO 2631 (1997) that estimates the incidence of motion sickness from vehicle motion, with frequencies below 1 Hz amplified to reflect human sensitivity."
用法说明 · 针对中文母语者
MSDV 最初源于航海领域（只考虑垂直方向），后被 Griffin 等人扩展到横向与纵向加速度以适用于汽车。设计自动驾驶 NDRT 时常用来评估行驶路线的晕动风险。
常见错误
- ·和 dose-response 概念混淆——MSDV 是单一合成指标，不是剂量-反应曲线
- ·以为只算一个轴——三维加速度都要纳入

"The ISO 2631 standard (ISO, 1997) defines a calculation based on the driving behaviour resulting in the 'Motion sickness dose value' (MSDV)."
"Griffin suggested that for the prediction of car sickness also longitudinal and lateral accelerations have to be considered and showed that the MSDV values in the x- and y-axes are similar when calculated using the frequency weighting in the current standards."
"An overall MSDV value taking into account accelerations in all three dimensions can be calculated as shown by Asua et al. (2022)."
