Long-term experience with accelerator pedal sensor technology
Use of robust HELLA CIPOS^® technology
Variable customer feedback specifications possible

The growing market for driver assistance systems and demand for lower fuel consumption has created a situation in which the interface between the driver and the accelerator pedal is of increasing significance.

HELLA has developed feedback accelerator pedal sensors to meet this growing demand. Haptic feedback is generated by a vibration motor. The vibration motor is integrated in a black box design which could be adapted to Hella standard APS. The haptic feedback will be controlled and adjusted by customer ECU.

Based on this technology the feedback could be used for economical driving and safety relevant topics.

Description

Feedback accelerator pedal sensors communicate directly with the driver by providing feedback in certain driving situations. Driving situations in which HELLA’s Feedback Accelerator Pedal comes into play include:

Electrical driving in hybrid cars: detecting the start of the combustion engine
Manual transmission: shifting detection to recognize shifting point by knocking signal
Need-based driving
Reduced fuel consumption and CO₂ emissions

The position measuring technology forms a key part of the feedback accelerator pedal sensor that demands a high degree of precision.

HELLA therefore uses its own sensor position technology, the contactless inductive position sensor (CIPOS^®), which is extremely precise, features a robust design and is integrated within a compact housing. Independent of the APS technology, the sensor is designed so that the pedal, the generation of the pedal force and the sensor are integrated within one modular design. This allows the design and haptics of the pedal to be tailored to customer requirements.
