1 The new KMT-CLS Steering Sensor Measurements at the original steering wheel of automobiles and trucks Small Flexible High accuracy

2 Structure Development targets Configuration Installation Measurement technique Security Conclusion

3 1. Development targets A modular smart & easy solution for mounting A bad solution from competitors

4 1. Development targets Maintained of the full functionality of the standard steering wheel Easy for mounting Minimum effects on measurement High accuracy

5 2. Configuration: A modular solution! Easy for mounting

6 2. Configuration : An integrated solution! Tight design Easy to mount Flexible application

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

8 3. Installation : Through connection Soldering pads at the upper side Soldering pads at the lower side 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

9 3. Installation : Mounting Steering Column Fit the adapter

10 3. Installation : Mounting Sensor Fit the sensor and tighten the central screw

11 3. Installation : Mounting Steering adapter Fit the adapter and tighten the screws

12 3. Installation : Mounting angle encoder Fit the angle encoder and tighten the screws Fixing of the torque bearing

13 3. Installation : Mounting Steering wheel Tighten the steering wheel and the central screws Mounting of the impact plate incl. Airbag Ready for take off!

14 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 Hz Direction of rotation: positive torque clockwise Temperature drift: max % FS/ K Angle sensor: Sensor type: incremental magnetic sensor Angle resolution: 0.04 (8800 steps/360 )

15 4. Measuring: The Control Unit Common Dimensions: ca. 80mm x 105mm x 185mm Weight: 1,15 kg Temperature range: - 20 C C Power supply: V/DC

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

17 4. Measuring: Analogue Outputs Output voltage: ± 10 V Analogue offset balance: by rotary potentiometer at the front plate Bandwidth: 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! Steering Torque Display (Nm) Rotation Angle Display (degrees) Only for factory setting! 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!

18 4. Measuring: What kind of technique? Frequence output for torque Type: Frequency range: Digital display 5 V TTL - rectangle signal Hz ± 5000 Hz 5000 Hz = Nm or Nm Hz = 0 Nm Hz = Nm or Nm 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

19 4. Measuring: Configuration

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

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!
