一种获取机动车需求扭矩的方法和装置
摘要：
本发明提供种获取机动车需求扭矩的方法和装置,所述方法包括:获取车速信号;判断所述车速信号是否正常;当所述车速信号正常时,确定需求扭矩T1,所述需求扭矩T1为动力系统输出扭矩T2与需求扭矩修正系数β的乘积,其中0≤β≤1,且当加速踏板下压加速度小于或等于预设阈值时,所述需求扭矩修正系数为1,当所述加速踏板下压加速度大于预设阈值时,所述需求扭矩修正系数随所述加速踏板下压加速度增大而减小。
摘要（英）：

The invention provides a method and device for obtaining motor vehicle demand torque. The method comprises the steps of obtaining vehicle speed signals; judging whether the vehicle speed signals are normal; when the vehicle speed signals are normal, determining demand torque T1, wherein the demand torque T1 is the product of power system output torque T2 and demand torque correction factor beta, and 0<=beta<=1; when the pressing-down acceleration of an accelerator pedal is smaller than or equal to a preset threshold, the demand torque correction factor is 1; and when the pressing-down acceleration of the accelerator pedal is larger than the preset threshold, the demand torque correction factor is reduced along with the increase of the pressing-down acceleration of the accelerator pedal.
