The invention relates to the technical field of new energy automobile control, in particular to an air conditioner heating PTC (Positive Temperature Coefficient) power control method which specifically comprises the following steps: S1, judging whether an enabling permission condition of a PTC heater is met or not, S2, sending a PTC control enabling signal, controlling a contactor in a high-voltage loop to be closed and controlling the PTC heater to release heating power, and S3, controlling the PTC heater to release heating power. S4, the VCU calculates the available power of a motor system in real time, and the VCU calculates the available maximum torque of a motor in real time, so that the problem that the power of the whole vehicle is possibly insufficient due to the fact that power consumption calculation is inaccurate at the present stage and the dynamic property of the whole vehicle is weakened at some key times is solved.

    本发明涉及新能源汽车控制技术领域,具体地说,本发明涉及一种空调加热PTC功率控制方法,具体包括以下步骤:步骤S1,判断是否满足PTC加热器使能的允许条件,步骤S2,发出PTC控制使能信号,控制高压回路中的接触器闭合,PTC加热器释放加热功率,步骤S3,VCU实时计算电机系统的可用功率,步骤S4,VCU实时计算电机的可用最大扭矩,解决现阶段功率消耗计算不准确,会在某些关键时候削弱了整车的动力性,从而使整车可能出现动力不足的现象的问题。
