Shift-by-wire gear selector switches

KOSTAL has been a supplier of mechatronic components to the automobile industry for many years and has now successfully conquered a new challenge in the field of centre console modules with the electronic gear selector lever.

The introduction of shift-by-wire gear selector switches in modern vehicles with automatic gearboxes is a trend which is now unstoppable. Their outstanding functionality and flexibility make them superior to previous systems in many respects. In addition, this new system gives the interior designer much greater scope in deciding the shape of the centre console.

The customer chooses

Centrally-located 3D control elements (latching systems) make it possible to meet individual customers‘ wishes and requirements in terms of layout and tactile feedback. Fully configurable actuators can hold the transmission system in the gear which has been selected, or move the gear lever automatically to achieve optimum performance, providing guidance for the driver to a degree which was previously unknown.

With this system, the gear selector switch can be integrated fully in line with minimum gap dimensions and design trends.

SIL requirements

Essential components of function software for the integrated electronic unit include error detection and compensation routines. These ensure maximum reliability of operation and system availability in accordance with the specified safety integrity level (SIL 2) for the entire system, including gearbox and transmission.

Single errors in the sensors for position recognition must be detected and corrected. In this way system availability is ensured if single errors occur. Duplicated errors are detected by the sensor system and do not result in incorrect position detection.
