Embodiment Construction

[0019] exist figure 1 In , an electromechanical power steering device 1 is schematically shown having a steering shaft 2 connected to a steering wheel 3 intended to be operated by the driver. The steering rack bar 4 is connected in known manner to steered wheels 5 of the motor vehicle. The rotation of the steering shaft 2 causes an axial displacement of the steering rack 6 via the pinion 7 , which is connected to the steering shaft 2 in a torque-resistant manner. The electromechanical power steering system 1 has a motor housing 8 on the steering column side. The motor housing 8 is connected to a control unit 9 which, among other signals, receives a torque signal from a torque sensor 10 via a signal line 11 and sends a corresponding control signal via a signal line 12 to the arrangement Servomotor 13 in housing 8 . The control unit 9 itself receives an input signal, eg vehicle speed, via a supply line 14 . The servo motor 13 is a permanently excited synchronous motor. The ...

Abstract

The invention relates to a current mirror arrangement for duplex bidirectional communication between two circuit units (A, B), said arrangement comprising in each said circuit unit (A, B) two identical transistors (34, 34', 35, 35'), the bases (36, 37) of the transistors (34, 34', 35, 35') are connected together and the transistors (34, 34', 35 , 35') the base and the collector are respectively connected to each other, wherein each connection between the base and the collector is formed by a MOSFET (38, 39, 40, 41), and the two The MOSFETs (38, 39, 40, 41) of the circuit units (A, B) are connected together, wherein, the parasitic diodes of the MOSFETs (38, 39, 40, 41) of each circuit unit (A, B) arranged in the opposite direction with respect to the current system.

Description

technical field [0001] The invention relates to a current mirror device and an electromechanical motor vehicle power steering device. Background technique [0002] Electromechanical steering generally has an electric motor as a servomotor. A servomotor of this design is actuated by a control unit via groups of metal-oxide-semiconductor field-effect transistors (MOSFETs), wherein a total of six MOSFETs are provided for the three phase windings. Each MOSFET switches the assigned phase winding to either the vehicle supply voltage or ground potential. This switching occurs at a higher frequency so that the instantaneous average value is used as the effective voltage in the phase winding. For safety reasons it is known to separate the phase wires in the neutral point of the motor. The split takes place in the Motor Control Unit (MCU), which is controlled with appropriate information from the Electronic Control Unit (ECU). Signal lines are used to transmit this information and...
