The invention relates to a new energy automobile torque monitoring method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring an accelerator pedal travel signal, a shift lever position signal and a vehicle speed signal and forming a torque control signal; calculating the required torque of a driver according to the torque control signal; calculating a safe torque value under the current working condition according to the torque control signal; calculating a difference value Tq between the required torque of the driver and the safe torque value under the current working condition; calculating an acceleration increment a according to the difference value Tq and the vehicle weight M, wherein a = Tq/M; when the acceleration increment absolute value a is larger than an acceleration threshold value, timing is started, and when the timing duration is larger than a preset time threshold value, it is judged that a demand torque monitoring fault occurs. According to the method, the required torque of the driver can be monitored, and when the analysis torque is found not to deviate from the requirement of the driver, the torque output of the power source is limited, so that the torque safety is improved from the source.

    本申请涉及一种新能源汽车扭矩监控方法、装置、计算机设备和存储介质。所述方法包括:获取加速踏板行程信号、换挡杆位置信号以及车速信号并形成扭矩控制信号;根据所述扭矩控制信号计算驾驶员的需求扭矩;根据所述扭矩控制信号计算当前工况下的安全扭矩值;计算驾驶员的需求扭矩与当前工况下的安全扭矩值的差值△Tq;根据差值△Tq与车重M计算加速度增量△a,其中△a=△Tq/M;当加速度增量绝对值|△a|大于加速度阈值时开始计时,且当计时时长大于预设时间阈值时,判断发生了需求扭矩监控故障。本方法能够对驾驶员的需求扭矩进行监控,当发现解析扭矩不偏离驾驶员需求时,限制动力源的扭矩输出,从源头上提高了扭矩安全。
