Abstract
A roll stabilizer for a motor vehicle includes a plurality of sensors for detecting a plurality of measurement variables, in particular a torque sensor, a rotor position sensor and optionally an actuator temperature sensor. Each of the sensors resides on a separate sensor circuit board which is separate from a motherboard. The motherboard has electronics for evaluating the measurement variables detected by the sensors and/or for forwarding said measurement variables to an external control device.
Claims20
A roll stabilizer for a motor vehicle comprising:
- an actuator having an actuator axis;
- a motherboard having an electronic module, the motherboard arranged to be transverse relative to the actuator axis;
- a rotor-position-sensor board arranged parallel to the motherboard and having a rotor-position sensor;
- and
- a torque-sensor board arranged transverse to the motherboard and having a torque sensor;
- wherein:
- the electronic module receives signals from the rotor-position sensor and the torque sensor;
- and
- the motherboard is arranged between the rotor-position-sensor board and the torque-sensor board.
A roll stabilizer for a motor vehicle comprising:
- an actuator having an actuator axis;
- a motherboard having an electronic module arranged thereon, the electronic module including:
- a signal acquisition and data processing unit;
- a data forwarding unit;
- a power supply unit;
- and
- a rotor-position-sensor board:
- arranged separately from and parallel to the motherboard;
- and
- having a rotor-position sensor arranged thereon;
- and
- a torque-sensor board:
- arranged separately from and transverse to the motherboard;
- and
- having a torque sensor arranged thereon;
- and
- wherein the electronic module is configured to receive a first signal from the rotor-position sensor and a second signal from the torque sensor.
A roll stabilizer for a motor vehicle comprising:
- an actuator having an actuator axis;
- a housing;
- an insertable holding element assembly configured to be installed as a unit assembly within the housing;
- the insertable holding element assembly having:
- a holding element including:
