application

SLIDE 7

3. Installation:

Adapter

Adapter we can deliver: Either blank adapter for manufacturing the special toothing by yourself or by ourself  then we need exactly drawings

SLIDE 8

3. Installation :

Through connection

At the soldering pads you can transfer up to 6 signals e.g. :

power supply
Airbag
Lin bus
…

The contacts you can use up to 4 Ampere

Soldering pads at the upper side Soldering pads at the lower side

4. Measuring: What kind of technique?

Steering torque:

Sensor integrated strain gage application: temperature compensated Measurement range: Nm 100 or 200 (choose when you order) Accuracy: % FS 0,2 Bandwidth: DC ... 800 Hz Direction of rotation: positive torque clockwise Temperature drift: max. 0.004% FS/°K

Angle sensor:

Sensor type: incremental magnetic sensor Angle resolution: 0.04° (8800 steps/360°)

SLIDE 15

4. Measuring: The Control Unit

Common

Dimensions:

ca. 80mm x 105mm x 185mm

Weight: 1,15 kg Temperature range:

20°C ... + 80°C

Power supply: 9 ... 36 V/DC

SLIDE 16

4. Measuring: CAN-Bus Interface

Electrical interface: ISO/DIN 11898 incl. galvanic isolation Configuration: at CAN by using CCP-protocols, the identification is raised by serial number Baud rate: 10 kBaud ... 1 MBaud configurable by software Identifier: 11 bit oder 29 bit free configurable Message configuration: free configurable Update rate:

max. 5000 Hz, divisible be configurable, integer factor

Torque range: ± 100 Nm or ± 200 Nm depending of the type Torque resolution: 16 bit (0,003 Nm or 0,006 Nm) Rotation angle range: ± 1340° Rotation angle resolution: 16 bit : 0,04° (8800 steps/360°) Rotation speed: ± 1000°/sec Rotation speed resolution: 16 bit

SLIDE 17

4. Measuring: Analogue Outputs

Output voltage: ± 10 V Analogue offset balance: by rotary potentiometer at the front plate Bandwidth: 0 ... 800 Hz Torque range: ± 100 Nm or ± 200 Nm as the type may be Torque resolution: 12 bit (0,049 Nm or 0,098 Nm as the type may be) Rotation angle channel: ± 1000° (= ± 10 V) Rotation angle resolution: 0,65°

Autozero Button

Activate only CAN Interface Not active for analog output!

Rotation Angle Display (degrees) Steering Torque Display (Nm) Analog Offset Trim for Steering Torque Analog Offset Trim For Steering Angle Analogue output for steering torque Frequency output for steering torque Analogue output for steering angle Out off function!

Only for factory setting!

SLIDE 18

4. Measuring: What kind of technique?

Frequence output for torque

Type: 5 V TTL - rectangle signal Frequency range: 10000 Hz ± 5000 Hz 5000 Hz = - 100 Nm or - 200 Nm 10000 Hz = 0 Nm 15000 Hz = + 100 Nm or + 200 Nm

Digital display

Torque display: ± 100 Nm or ± 200 Nm for direct reading Torque display resolution: 0,1 Nm Rotation angle display: ± 1000° for direct reading Rotation angle display resolution: 1°

4. Measuring: Configuration

SLIDE 20

5. Security
Airbag will be full in function
Test driver will not be influenced by the measuring
All functions of the standard steering wheel you can

use without constrictions

Mechanical fracture torque > 500 Nm
Additional mechanical protection against breakage

is integrated

SLIDE 21

6. Conclusion
Very fast integration in a test vehicle
You can use the complete functionality of the standard

steering wheel

You can use the CLS in nearly all kinds of vehicles

(cars, trucks, tractors, military …)

Optimal signal resolution
Minimum effects on measurement

The new steering sensor – a fantastic solution!
