The invention discloses a torque filtering method and device, and relates to the technical field of electric vehicle control. The method comprises the steps that whether a historical required torque value is within a preset torque zero-crossing interval or not is judged, wherein the historical required torque value is a required torque value obtained after torque filtering processing in the previous torque filtering processing process; if the historical required torque value is outside the preset torque zero-crossing interval, a first-order inertia filtering method is adopted for calculating afirst filtering torque value; according to the torque slope corresponding to the first filtering torque value and a preset slope threshold value, the first filtering torque value is corrected to obtain a corrected filtering torque value; and the corrected filtering torque value is determined as a current required torque value. The torque filtering method and device are suitable for the process ofconducting torque filtering processing on target torque.
本申请公开一种扭矩滤波方法及装置,涉及电动汽车控制技术领域。本申请的方法包括:判断历史需求扭矩值是否处于预设扭矩过零区间内,其中,所述历史需求扭矩值为前一扭矩滤波处理过程中经过扭矩滤波处理后得到的需求扭矩值;若所述历史需求扭矩值处于所述预设扭矩过零区间外,则采用一阶惯性滤波法计算第一滤波扭矩值;根据所述第一滤波扭矩值对应的扭矩斜率和预设斜率阈值,对所述第一滤波扭矩值进行修正处理,以获得修正滤波扭矩值;将所述修正滤波扭矩值确定为当前需求扭矩值。本申请适用于对目标扭矩进行扭矩滤波处理的过程中。
