The invention relates to a method for determining an engine reference torque (MRM) of an engine of a motor vehicle for use in a control unit (60, 62) of the motor vehicle, the engine reference torque (MRM) being determined by an estimation (46). In this case, a value of the mass (m) of the motor vehicle is calculated, and a motor vehicle speed value (v (t1), v (t2)) is ascertained in each case at two different times (t1, t2) during acceleration of the motor vehicle. The engine power (P ', P) of the engine is calculated from these values (m, v (t1), v (t2)), and in combination with the calculated engine power (P', P), the value of the engine reference torque (MRM) is estimated based on a power and torque curve (16) stored as a function of the engine speed (nM).
本发明涉及用于确定在机动车的控制器(60、62)中使用的机动车的发动机的发动机参考力矩(MRM)的方法,其中,通过估算(46)确定发动机参考力矩(MRM)。在此,计算机动车的质量(m)的值,在机动车加速期间在两个不同时间点(t1、t2)时分别获知的机动车速度值(v(t1)、v(t2))。根据这些值(m、v(t1)、v(t2))计算发动机的发动机功率(P’;P),并且结合计算出的发动机功率(P’;P),基于以发动机的转速(nM)的函数来存储的功率和力矩曲线(16),估算发动机参考力矩(MRM)的值。
