Position sensors support
ASIL D capable assistance systems

AB Elektronik’s position sensors support ASIL D capable assistance systems for braking force control and recuperation
AB Elektronik stands for the development and worldwide production of position sensors based on versatile technologies, and with different electronic interfaces. Our position sensors have already proven themselves millions of times in automotive applications, and take on important functions in new types of assistance systems.

Position sensors for the assistance of braking processes
By sensing the pedal position, the driver’s braking demand is detected and interpreted by the downstream systems. Common applications are brake boosting and emergency braking assistance, i.e. safety-related systems. In the future, they will be used across all vehicle classes to increase safety on the road. Position sensors from AB Elektronik require little installation space and can be integrated economically using modular concepts.

Position sensors initiate recuperation
In electric vehicles it is also about the recuperation of the braking force, which replenishes the battery charge and thus increases the available range. Depending on the vehicle model, the rate of recuperation is specified by the electronics, and the process is initiated by detecting the accelerator pedal or brake pedal positions. With the appropriate system settings, it is even possible to drive a vehicle in normal road traffic using only the accelerator pedal, the brake being needed only for emergency braking.

Safety-relevant functions for position sensors
The requirements for these systems are very high, and again the detection of position is the trigger for safety-relevant processes in the vehicle. AB Elektronik supports the application with position sensors that meet corresponding FUSI requirements on the ASIL C level.

Broad technology base and many years of field experience
Different sensor technologies allow individual tailoring of the product characteristics to the respective application. Interfaces including analog, PWM, PSI5, SENT, CAN, LIN and other protocols are possible.

The individual design of position sensors is based on the selection of the optimal technology for the application, in combination with a suitable mechanical interface. Based on an advanced overmolding technology developed by AB Elektronik, we use the excellent properties of thermoplastic and thermoset to create solutions with integrated sensor technology. However, we are also happy to offer molded or laser-welded cover solutions if this is the optimal solution for your application.
