用于在不使用传感器的情况下提高压力检测的准确性的方法
摘要：
本发明涉及一种用于确定机动车辆的流体输送系统中的压力值的方法，该流体输送系统具有可致动的电动机并且具有可以由该电动机驱动的流体给送泵，其中，该方法包括以下步骤：‑确定该电动机的转速；‑确定该电动机的致动电流；‑根据该电动机的转速和该致动电流获取压力值；‑在控制单元中使用至少一个外部状态变量对获取的压力值进行处理；以及‑校正获取的压力值。
摘要（英）：

A method for determining a pressure value in a fluid conveying system of a motor vehicle, the vehicle having an actuable electric motor and having a fluid feed pump drivable by the electric motor, includes: determining a rotational speed of the electric motor; determining an actuation current of the electric motor; acquiring a pressure value as a function of the determined rotational speed and the determined actuation current of the electric motor; processing the acquired pressure value with at least one external state variable in a controller; and correcting the acquired pressure value.
