Abstract
The behavior characteristics of steering maneuvre has important influences on the handling stability and driving safety, and becomes an important consideration in designing several driving assistance systems such as electric power steering system (EPS). The electromyography (EMG) signals of driver’s shoulder and limb muscles were studied to reveal certain behavior characteristics of these muscles involved in steering maneuvre in the paper. Based on the analysis of EMG signals, the muscles roles and main muscles in steering maneuvre were identified. The results showed that the clavicular portion of pectoralis major and anterior deltoid were the main agonists in counterclockwise steering maneuvre but the main antagonists in clockwise steering maneuvre, the triceps long head was the main antagonist in counterclockwise steering maneuvre but the main agonist in clockwise steering maneuvre. With classification of these muscles’ roles, their activity orders would be studied in Part 2 papers of this research, and others behavior characteristics in physiology of steering maneuvre would be studied in future research.
