The invention relates to an integrated pedal feeling simulator with changeable feeling and a control method, and aims to solve the problem of low sensitivity of existing pedal feeling simulation. The mechanical structure is used for generating first counter-acting force, the electromagnetic structure is used for generating second counter-acting force, and when the absolute value of the difference value of actual feedback pedal force corresponding to the first counter-acting force and pedal stress is larger than a set pedal force threshold value, the electronic control unit controls the electromagnetic structure to be powered on to generate the second counter-acting force. The second reacting force is regulated and controlled by adjusting the current until the absolute value of the difference value between the actual feedback pedal force corresponding to the sum of the first reacting force and the second reacting force and the pedal stress is smaller than or equal to the set pedal force threshold value; and when the displacement of the pedal is not zero, the electric control unit always adjusts current according to the stress of the pedal to realize self-adaptive adjustment of the pedal feeling, and when the electromagnetic structure is powered off and fails, the mechanical structure can realize pedal feeling simulation, so that the function safety of the system is ensured, the structure is integrated, and the mounting space is saved.

    本案涉及一种集成式可变感觉的踏板感觉模拟器及控制方法,旨在解决现有踏板感觉模拟灵敏度低的问题。该案利用机械结构产生第一反作用力,电磁结构产生第二反作用力,当第一反作用力对应的实际反馈踏板力与踏板受力差值的绝对值大于设定的踏板力阈值时,电控单元控制电磁结构通电产生第二反作用力,并通过调节电流来调控第二反作用力,直至第一反作用力和第二反作用力之和对应的实际反馈踏板力与踏板受力差值的绝对值小于等于设定的踏板力阈值;并在踏板位移未为0时,电控单元始终根据踏板受力调节电流,实现踏板感觉自适应调整,且当电磁结构发生断电失效情况时,机械结构可实现踏板感觉模拟,保证系统功能安全,结构集成节省安装空间。
