The invention discloses a friction torque compensation method and device. When the state of the engine is changed or the rotating speed interval is changed, the deviation value of the friction torque is obtained, the deviation storage value and the recording frequency storage value of the friction torque in the current rotating speed interval are read, and a to-be-stored value is obtained according to the deviation storage value and the deviation storage value so as to update the deviation storage value of the friction torque in the current rotating speed interval. And when the engine operates normally, the deviation storage value of the friction torque is obtained to compensate the friction torque. The friction torque of the whole life cycle of the engine can be corrected in real time, so that the accurate torque is obtained, and the problem that the friction torque is changed due to abrasion and aging of a friction pair, deterioration and deterioration of engine oil and the like is solved.

    本申请公开了一种摩擦扭矩补偿的方法及装置。当发动机状态改变或转速区间发生改变时,获取摩擦扭矩的偏差值,读取当前转速区间内,摩擦扭矩的偏差存储值和记录次数存储值,根据二者和偏差值得到待存储值,以更新当前转速区间内摩擦扭矩的偏差存储值。待发动机正常运行时,获取摩擦扭矩的偏差存储值来对摩擦扭矩进行补偿。能够满足对发动机整个生命周期的摩擦扭矩的实时修正,从而得到准确的扭矩,解决了因摩擦副磨损和老化、机油劣化变质等造成摩擦扭矩改变的问题。
