摘要： A method of transitioning a motor from a torque control mode to a speed control mode includes providing the motor with a torque command to eliminate torque holes at the transition. A speed controller generates a speed error, which is used to generate two torque terms. The first torque term is proportional to the speed error, and the second torque term includes the integral of the speed error. A third torque term comprises a feedforward torque, which is added to the first two torque terms to generate the torque command.

摘要： A method is provided for controlling an electro-hydraulic power assist steering system including a variable-speed electric motor for pumping hydraulic fluid in the system. The method includes monitoring vehicle speed and vehicle steering wheel angle. A vehicle yaw rate is estimated using the monitored vehicle speed and monitored vehicle steering wheel angle. A control signal for setting the speed of the variable speed electric motor is compensated based based on the estimated vehicle yaw rate. Accordingly, a wide range of vehicle driving conditions are accommodated and vehicle fuel efficiency is improved.

摘要： A method and apparatus for determining a center position of the vehicular steering system includes a vehicle speed sensor, a steering sensor and a control unit. The control unit uses a strategy to determine an estimate of the steering assist force. When the steering assist force is below a force threshold and a vehicle speed is above a speed threshold, the controller filters data from the steering sensor so as to rapidly determine a precise center position for the steering system.

摘要： A method is provided for controlling an electro-hydraulic power assist steering system including a variable-speed electric motor for pumping hydraulic fluid in the system. The method includes monitoring a vehicle steering wheel angle and determining if the vehicle steering wheel angle exceeds a steering travel limit. If the steering travel limit is exceeded, the method reduces a desired motor speed to a predetermined end of travel motor speed until the steering wheel angle drops below the steering travel limit. Accordingly, energy is conserved by reducing the power consumed while the steering system is maintained at its steering travel limit.
摘要翻译：提供了一种用于控制电液动力辅助转向系统的方法，该电动助力转向系统包括用于泵送系统中的液压流体的变速电动机。该方法包括监视车辆方向盘角度并确定车辆方向盘角度是否超过转向行驶极限。如果超过转向行程限制，则该方法将期望的电动机速度降低到行驶电动机速度的预定结束，直到方向盘角度低于转向行驶极限。因此，通过在转向系统维持在其转向行驶极限时减少消耗的功率来节省能量。

摘要： An extruder press unit for extrusion of a thermoplastic material has at least one output gap in an extruder body, wherein the output gap is formed by an output gap-defining adjustable extruder lip and an opposing gap-bounding lip. This output gap is adjustable with the help of a mechanical coarse adjusting mechanism to a given gap width, and the gap-defining adjustable extruder lip is connected to at least one adjusting element, to which a control and adjusting device for the thickness of the extruded material is associated. The opposing gap-bounding lip is likewise constructed as an adjustable structural component. The coarse adjusting mechanism operates on the opposing gap bounding lip. A field translator is employed as at least one of the adjusting elements and of course in the form of either a piezotransistor or a magnetrostriction translator. The control and adjusting device is set up for a fine adjustment in the range between 0.05 and 0.3 mm, preferably between 0.10 to 0.20 mm.

The method includes monitoring vehicle speed, vehicle steering wheel angle, and vehicle steering wheel turning rate. A parking mode or a driving mode is selected based upon the monitored vehicle speed.
