Sensing

Position sensors

Position sensors from AB Elektronik monitor, among other things, linear paths and the properties of battery cells. In modern vehicles, position sensors support the fast and precise comparison between the perception of the camera and radar systems and the actual condition of the vehicle.
AB Elektronik has a broad technology portfolio and close links with the semiconductor industry. We stay close to selected research centres, and ensure we stay right ‘on the pulse’ to meet the dynamic requirements of the market.


We equip our products with efficient, energy saving technology, and supplement micro power ICs or even passive components for wake-up functions with special power consumption requirements. Using innovative manufacturing processes, we produce robust, but slim and lightweight solutions with weight-optimized design. We identify the right package for your current requirements, and act as your well informed consultant for future applications.


Recuperation - Brake pedal travel

Position sensors on the brake pedals enable fast and accurate detection of the braking intention. A light application of the brake decelerates the vehicle by generating charging current via the driveline instead of activating the mechanical brakes. This extends the vehicle range and protects the environment.

Characteristics:

  • Channel: 2
  • Linearity: +/-1% 
  • Sealing: IP6K9K
  • Output signals: Analog, PWM, PSI5, Sent
  • Temperature range: -40 °C to + 80 °C
  • ASIL: B

 

Battery condition

Mechanical condition monitoring of the battery cells: Depending on the type deployed (prismatic, cylindrical, cushion), battery cells are subject to different deformations during charging and discharging cycles. Our inductive approach to battery monitoring provides non-contact reliable information about the current state of deformation, and serves as a reference for battery ageing.


Characteristics

  • Air gap Measurement: 4-10 mm range     
  • Resolution: 10 - 12 Bit
  • ASIL: B(D)
  • Linearity error: < 0,125mm

Vehicle level

Modern vehicles perceive their environment independently via camera and radar systems. The fast and precise comparison of this information with the actual condition of the vehicle reveals any need for action for a safe and comfortable journey. Our position sensors in a weight-optimized design continuously detect the chassis position, and provide the necessary information for assistance systems. This is indispensable, especially for autonomous driving.


Characteristics:

  • Linearity: +/-1%
  • Sealing: IP6K9K
  • Output signals: Analog, PWM, PSI5, SENT
  • Temperature range: -40 °C to +125 °C
  • ASIL: B

Driver Demand Controls

The accelerator pedal is a key direct interface between the vehicle and its user. In a very special way, it conveys the brand promise of the vehicle manufacturer.
The design of the accelerator pedal provides another opportunity to deliver on the expectations of the brand. Accelerator pedals from AB Elektronik convey positive feelings of quality and safety - for a rewarding driving experience.
The technology in our active accelerator pedals supports the dynamic driving experience of electric and hybrid drives. Using haptic signals, they alert the driver to a change of drive mode from or to the combustion engine. At the same time, our mature products convey confidence and safety, supported by the cumulative experience of more than 20 years of development and production of electronic accelerator pedals.

Motor Position Sensor

An inductive high speed rotor position sensor (SPINpad sensor)

A combination of high accuracy and fast response time is required for rotor position sensors in the electric motors of hybrid or electric vehicles. This allows the control unit to drive the motor optimally, and leads to a reduction in energy consumption and an increased range of the vehicle.

 

AB Elektronik has developed a new high speed position sensor to meet these requirements. First prototypes of this new sensor have demonstrated market leading performance. This technology can be used in other applications where accuracy and response times are critical (for example, electric power steering), and is also capable of making an additional velocity measurement, which could be used in active suspension systems.

 

The basic structure of the SPINpad sensor is similar to AB Elektronik‘s mature and proven Autopad® technology. However, the SPINpad sensor uses one coil as a transmit coil and two coils as receive coils.

 

Typical applications

  • High speed accurate sensing of the rotor position in electric and hybrid vehicles motors
  • Electric Power Steering
  • Electric Motor traction drive
  • Active suspension systems

Special features

  • Flexible designs, can be matched to motor pole-pairs giving positional accuracy < 0.5deg electrical
  • Different targets available
  • Signal immediately after power on
  • High speed up to 100,000 rpm
  • Ready for ASIL C (D) or with redundant measurement ASIL D (D)
  • Immune to low frequency magnetic fields
  • Small package size, flat design
  • Temperature range: -40 °C to 160 °C
