The invention discloses an intelligent driving transverse torque control method and system and a storage medium, and relates to the field of torque adjustment. The method comprises the following steps: after receiving a target torque request, superposing a vibration parameter on a target torque to obtain a response torque; when the target torque is positive, the superposition mode of the vibration parameters is the addition of the target torque and the vibration parameters, and when the target torque is negative, the superposition mode of the vibration parameters is the subtraction of the target torque and the vibration parameters; the response torque is used to determine a current controlling the electric machine. When the torque request is responded, a vibration parameter is superposed during response, so that the steering gear rack can vibrate quickly, conversion from static friction to dynamic friction between the steering gear rack and the rack pressing block can be realized on the basis of not needing too large torque, the response time is shortened, and the reliability of the steering gear rack is improved. Moreover, the response overshoot is reduced, and the response characteristic of the EPS is improved.

    本发明公开了一种智能驾驶横向扭矩控制方法、系统及存储介质,涉及扭矩调整领域。该方法的步骤包括:收到目标扭矩请求后,为目标扭矩叠加振动参数得到响应扭矩;当目标扭矩正数时,振动参数的叠加方式为目标扭矩与振动参数相加,当目标扭矩为负数时,振动参数的叠加方式为目标扭矩与振动参数相减;响应扭矩用于:确定控制电机的电流。本申请在响应扭矩请求时,在响应的同时会叠加一个振动参数,进而可以让转向器齿条快速振动起来,这样就可以在不需要过大的力矩的基础上,在转向器齿条与齿条压块之间实现从静摩擦到动摩擦的转换,进而不仅缩短了响应时长,而且减小了响应超调量,提升了EPS的响应特性。
