The invention relates to a torque compensation method and device for a steering wheel dead zone, computer equipment and a medium. The method comprises the steps that request torque of a vehicle in a current detection period and first request torque information corresponding to the request torque are obtained, and multiple pieces of second request torque information of the request torque in multiple detection periods before the current detection period are obtained; according to the first request torque information and the multiple pieces of second request torque information, the direction change and the change trend of request torque are determined; if the direction change is non-reversing and the change trend is continuously increasing or continuously decreasing, determining a dead zone mark as a first mark for representing that the steering wheel is in a dead zone; and determining a dead zone compensation torque, and compensating the request torque based on the dead zone compensation torque to obtain a target torque. By adopting the method, the dead zone judgment accuracy can be improved.

    本申请涉及一种方向盘死区的扭矩补偿方法、装置、计算机设备、介质。所述方法包括:获取车辆在当前检测周期内的请求扭矩和所述请求扭矩对应的第一请求扭矩信息,以及获取在所述当前检测周期之前的多个检测周期中请求扭矩的多个第二请求扭矩信息;根据所述第一请求扭矩信息和多个所述第二请求扭矩信息,确定请求扭矩的方向变化和变化趋势;若所述方向变化为未换向且所述变化趋势为连续递增或连续递减,确定死区标志为用于表征方向盘处于死区的第一标识;确定死区补偿扭矩,并基于所述死区补偿扭矩对所述请求扭矩进行补偿,得到目标扭矩。采用本方法能够提高死区判断准确性。
