The aim of this study was to compare the correlation between electromyography (EMG) activity and vehicle motion during double lane change driving. This study measured five vehicle motions: the steering wheel angle, steering wheel torque, lateral acceleration, roll angle, and yaw velocity. The EMG activity for 19 muscles and vehicle motions was applied for envelope detection. There was a significantly high positive correlation between muscles (mean correlation coefficient) for sternocleidomastoid (0.62) and biceps brachii (0.71) and vehicle motions for steering wheel angle, steering wheel torque, lateral acceleration, and yaw velocity, but a negative correlation between the muscles for middle deltoid (-0.75) and triceps brachii long head (-0.78) and these vehicle motions. The ANOVA test was used to analyze statistically significant differences in the main and interaction effects of muscle and vehicle speed. The mean absolute correlation coefficient exhibited an increasing trend with the increasing vehicle speed for the muscles (increasing rate%): upper trapezius (30.5%), pectoralis major sternal (38.7%), serratus anterior (13.3%), and biceps brachii (11.0%). The mean absolute correlation coefficient showed a decreasing trend with increasing vehicle speed for the masseter (-9.6%), sternocleidomastoid (-12.9%), middle deltoid (-5.5%), posterior deltoid (-20.0%), pectoralis major clavicular (-13.4%), and triceps brachii long head (-6.3%). The sternocleidomastoid muscle may decrease with increasing vehicle speed as the neck rotation decreases. As shoulder stabilizers, the upper trapezius, pectoralis major sternal, and serratus anterior muscles are considered to play a primary role in maintaining body balance. This study suggests that the primary muscles reflecting vehicle motions include the sternocleidomastoid, deltoid, upper trapezius, pectoralis major sternal, serratus anterior, biceps, and triceps muscles under real driving conditions.
本研究旨在比较双车道变道驾驶过程中肌电图（EMG）活动与车辆运动之间的相关性。本研究测量了五个车辆运动：方向盘转角、方向盘扭矩、横向加速度、横滚角和偏航速度。将 19 块肌肉的 EMG 活动应用于包络检测。胸锁乳突肌（0.62）和肱二头肌（0.71）的肌肉与方向盘转角、方向盘扭矩、横向加速度和偏航速度之间存在显著的正相关，而中三角肌（-0.75）和肱三头肌长头（-0.78）与这些车辆运动之间存在负相关。采用方差分析（ANOVA）检验肌肉和车速的主效应和交互效应的统计学差异。平均绝对相关系数随着肌肉（增长率%）的增加而呈上升趋势：上斜方肌（30.5%）、胸大肌胸骨（38.7%）、前锯肌（13.3%）和肱二头肌（11.0%）。随着车速的增加，咀嚼肌（-9.6%）、胸锁乳突肌（-12.9%）、中三角肌（-5.5%）、后三角肌（-20.0%）、胸大肌锁骨（-13.4%）和肱三头肌长头（-6.3%）的平均绝对相关系数呈下降趋势。随着车速的增加，胸锁乳突肌的活动可能会减少，因为颈部旋转减少。作为肩部稳定器，上斜方肌、胸大肌胸骨和前锯肌被认为在维持身体平衡方面起着主要作用。本研究表明，在实际驾驶条件下，反映车辆运动的主要肌肉包括胸锁乳突肌、三角肌、上斜方肌、胸大肌胸骨、前锯肌、二头肌和三头肌。
