The invention discloses a torque control method, device and equipment of a new energy automobile and a storage medium, applied to a controller, the controller comprises a monitoring layer module and a functional layer module, the functional layer module is used for calculating an actual value of a motor demand torque, and the monitoring layer module is used for calculating a monitoring value of the motor demand torque. The torque control method comprises the following steps: a monitoring layer module obtains a first monitoring value and a first actual value for a first motor demand torque; under the condition that a first difference value between the first actual value and the first monitoring value exceeds a first safety threshold value, the first motor demand torque is reduced, and a second motor demand torque is obtained and output to the functional layer module; acquiring a second actual value and a second monitoring value for a second motor demand torque; and under the condition that a second difference value between the second monitoring value and the second actual value exceeds a second safety threshold value, the second motor demand torque is set to be zero. Through the technical scheme provided by the invention, the safety risk caused by false triggering of torque monitoring can be reduced.

    本申请公开了一种新能源汽车的扭矩控制方法、装置、设备及存储介质,应用于控制器,控制器包括监控层模块和功能层模块,功能层模块用于计算电机需求扭矩的实际值,监控层模块用于计算电机需求扭矩的监测值,扭矩控制方法包括:监控层模块获取针对第一电机需求扭矩的第一监测值和第一实际值;在第一实际值与第一监测值的第一差值超过第一安全阈值的情况下,降低第一电机需求扭矩,得到并输出第二电机需求扭矩至功能层模块;获取针对第二电机需求扭矩的第二实际值和第二监测值;在第二监测值与第二实际值的第二差值超过第二安全阈值的情况下,将第二电机需求扭矩设置为零。通过本申请提供的技术方案能够降低扭矩监控的误触发带来的安全风险。
