| Automotive Applications - Absolute Track Accuracy
Novotechnik sensors help produce automobile chassis drives with absolute track accuracy. They control robotic systems used to weld car bodies and frames. They provide input for skid control. They help optimize fuel control as part of motor management accelerator/throttle control systems.
In both component and assembly operations, here, in Europe and in the Far East, Novotechnik is working with the industry leaders -- with BMW, Bosch, DaimlerChrysler, Ferrari, and Porsche - to help implement new control and safety systems as well as in production automation.
When passing at high speeds, a high sideways force is exercised on the rear wheels. This force is at the border of what could cause a break-away slide of the car. If the rear wheels are steered as well (max. 5°), the car drives as if on rails. The steering and driving behaviour is greatly improved.
A hydraulic position controller in the rear axle steers the rear wheels dependant upon the position of the front wheels. The position of the front wheels is measured by a steering angle sensor. A mechanically and electrically redundant linear postion transducer from Novotechnik is located in the hydraulic position controller.
On-board computers are used in Formula 1 racecars to achieve optimal motor management. The SP2800 potentiometric sensor measures each gas pedal movement and transmits the data to the computer.
The gearshift is controlled from the steering wheel of the car. A P4500 rotary potentiometer is used to position the hydraulic rotary drive of the gear. This potentiometer measures the various gears with a high precision - even under extreme vibrations and temperature changes.
