An electric motor assembly is configured to determine a motor winding resistance value. Predicted values are determined for a first and second position of motor commutator sections relative to the motor brushes, with at least one of the brushes contacting different numbers of the sections in the first position and the second position. The predicted values are based on a temperature value measured by the temperature sensor and a predetermined dependence of variation of the motor resistance dependent on the temperature value. An electric motor current value is measured by a current sensor when the electric motor is substantially at standstill. A selection is made between different factors for determining the motor resistance value using the electric current value, dependent on which of the predicted values most closely corresponds to the electric current value. The motor resistance is determined using said electric current value according to the selected factor.

Resistance determination in an electric motor assembly

A control unit is presented for controlling a driving unit arranged for adjustment of one or more first air guiding flaps of a motorised vehicle between a first outer position and a second outer position. The control unit comprises a communication module for communicating with a vehicle control network for receiving first adjustment instructions for adjusting the first flap, a power supply module comprising an input power terminal for receiving power from a vehicle power network and a first output power terminal for supplying a first current to the driving unit. The control unit further comprises a current sensor module for sensing variations in the first supply current and a control module arranged to control the first supply current in accordance with the adjustment instructions and the sensed variations. By separating the control module from the driving unit, functionality of the control module may be shared over multiple driving units.

Control module for adjusting flaps of a vehicle

An adjustable exterior mirror on a vehicle, or another kind of settable unit for installation in or on the vehicle, signals a sensor signal via the current through the current conductors for the supply current of a motor, heating or other function holder in the vision unit. In response to external switching-on of a supply voltage between the current conductors, for example from the vehicle, an aspect of the current is sensor-dependently controlled from the settable unit. In the vehicle, the aspect of the current through at least one of the current conductors is measured during a delay time interval after switching-on of the supply voltage to read out the sensor result.

Settable unit for installation in or on a vehicle

The invention relates to an actuator mechanism () for adjusting the orientation of a mirror element in an exterior mirror unit of a vehicle. The mechanism comprises an electric motor () with a driving shaft (), a drive train (), and a movable mirror adjusting element () coupled via the drive train to the driving shaft of the electric motor. Also, the actuator mechanism comprises an actuator frame () which carries the electric motor, the drive train and the mirror adjusting element. The driving shaft of the electric motor is bearing mounted in the actuator frame.

The invention relates to a system for adjusting at least two sets of shutoff elements of an air intake of a motor compartment of a motor vehicle. The system comprises at least two adjustment units. Each adjustment unit comprises a drive unit comprising an electric motor and a drive train for adjusting a set of shutoff elements. One adjustment unit is a primary adjustment unit and a further adjustment unit is a secondary adjustment unit. The primary adjustment unit is arranged for primary connection with a central control unit, such as an onboard computer of a motor vehicle. Also, the primary adjustment unit is arranged for secondary connection with the secondary adjustment unit. In the system the secondary adjustment unit has no direct connection with the central control unit.

The invention relates to an adjustment device for adjusting shutoff elements of an air inlet of a motor compartment of a motor vehicle between at least a first position in which the air inlet is substantially closed and a second position in which the air inlet is substantially open. The adjustment device comprises a drive unit. The drive unit comprises a drive train, an electric motor with an output shaft for driving the drive train, and a drive shaft. The drive train comprises at least one reduction element. The reduction element, the output shaft of the electric motor, and the output shaft of the adjustment device form drive elements of the drive unit. The adjustment device is provided with a condition determining unit for determining a motion condition of at least one of the drive elements.

Adjustment device and method for adjusting shutoff elements

An electric motor circuit for controlling an electric motor of a mirror adjustment mechanism includes a switch-off circuit that is provided with a current sensor for measuring the electrical supply current and, depending thereon, generating a voltage. In an embodiment, a current branch is configured to be rendered conductive in response to the generated voltage; an electronic switch is configured to interrupt the supply current as a result of the current branch being rendered conductive. The current branch may be configured to form a first branch of a current mirror which is out of balance and is dimensioned such that the first branch does not carry current under normal operating conditions of the motor, and a second branch is conductive. In an embodiment, upon the occurrence of a supply current that is greater than a predetermined critical level, the first branch is also rendered conductive.

Mirror adjustment mechanism, wing mirror unit and method

An electric motor circuit utilized, for instance, for adjusting a wing mirror of a vehicle is provided with a motor with a driving circuit. The driving circuit includes a relay switch element included in series with the motor and a protecting circuit for bringing the relay switch element into a non-conductive position at overload of the motor. The protective circuit is provided with an exciting coil and a deenergizing coil. The exciting coil serves for bringing the relay switch element into a conductive position. The exciting coil is included parallel to the motor in series with the relay switch element. The deenergizing coil is included in series with the motor for bringing the relay switch element in a non-conductive position when a current through the deenergizing coil and the motor exceeds a threshold value. Motor and motor protection are preferably included together in the housing of a mirror construction.
