The invention relates to a new energy vehicle overload automatic detection method. The method comprises the following steps: step 100, setting a standard speed corresponding to a motor rated voltage UN under a rated load M in a motor driver; 200, acquiring historical kinematics feature data of the new energy vehicle, and extracting the most effective kinematics fragment; 300, in the running process of the new energy vehicle, the current motor speed speedt is obtained, and the standard speed standard speedt corresponding to the current motor running voltage Ut is calculated; step 400, a difference value diffracted between the current motor speed speedt and a standard speed standard speedt corresponding to the current motor operation voltage Ut is calculated, and an optimal threshold value threshold speed of the difference value between the current motor speed speedt and the standard speed standard speedt corresponding to the current motor operation voltage Ut is calculated, and the optimal threshold value threshold speed of the difference value between the current motor speed speedt and the standard speed standard speedt corresponding to the current motor operation voltage Ut is calculated; and step 500, comparing the difference value diffspeed with the optimal threshold value threshold speed, and if the difference value diffspeed is greater than the optimal threshold value threshold speed, judging that the new energy vehicle is overloaded, and giving an overload alarm, and if the difference value diffspeed is greater than the optimal threshold value threshold speed, judging that the new energy vehicle is overloaded, and if the difference value diffspeed is greater than the optimal threshold value threshold speed, judging that the new energy vehicle is overloaded. And judging that the new energy vehicle is not overloaded if the diffracted is smaller than the optimal threshold value thresholdspeed, and if the diffracted is smaller than the optimal threshold value thresholdspeed, judging that the new energy vehicle is not overloaded.

    本发明涉及一种新能源车辆超载自动检测方法,包括:步骤100:在电机驱动器中设置在额定负载M下,电机额定电压UN对应的标准速度standard_speed;步骤200:获取新能源车辆历史运动学特征数据,并提取最有效运动学片段;步骤300:新能源车辆在行驶过程中,获取当前电机速度speed_t,并计算出当前电机运行电压Ut对应的标准速度standard_speed_t;步骤400:计算出当前电机速度speed_t与当前电机运行电压Ut对应的标准速度standard_speed_t差值diff_speed,以及计算出当前电机速度speed_t和当前电机运行电压Ut对应的标准速度standard_speed_t差值的最优阈值threshold_speed;步骤500:对比差值diff_speed和最优阈值threshold_speed,若差值diff_speed大于最优阈值threshold_speed时,判定新能源车辆超载,并进行超载报警;若diff_speed小于最优阈值threshold_speed时,判定新能源车辆未超载。
