用于由内燃机的凸轮轴信号来模拟内燃机的曲轴信号的方法
摘要：
本发明涉及一种用于由内燃机的凸轮轴信号来模拟内燃机的曲轴信号K（z）的方法。在这方面，在所述内燃机的正常运行中针对所述内燃机的至少一个转速范围并且/或者针对所述内燃机的至少一个运行状态获取曲轴位置传感轮的齿z的所有齿时间，并且由所述齿时间针对每个齿z计算用于相应的转速范围和/或运行状态的校正因数F（z），并且在所述内燃机的紧急运行中由凸轮轴信号来确定所述曲轴位置，并且随后模拟所述曲轴信号，方法是：由凸轮轴信号确定所述曲轴位置传感轮的每个齿z的平均的周期持续时间P（z）并且相应地将其与用于该齿z的校正因数F（z）相乘。
摘要（英）：

In a method for simulating a crankshaft signal of an internal combustion engine from a camshaft signal, in a normal operating mode of the engine, for at least one rotational speed range and/or for at least one operating state of the engine all tooth times of the teeth of a crankshaft position encoder wheel are trained, and, from these, for each tooth a correction factor is calculated for the corresponding rotational speed range and/or operating state, and in an emergency operating mode of the engine, the crankshaft position is determined from the camshaft signal, and subsequently the crankshaft signal is simulated by determining an average period duration of each tooth of the crankshaft position encoder wheel from the camshaft signal, and multiplying in each case by the correction factor for this tooth.
