Automotive Application - Hands on Detection

Hands on Wheel Detection

ams, experts in capacitive sensing, has launched a reliable and precise human presence sensor. This sensor measures the impedance that originates between a target (conducting plate) and a human.

The future is autonomous driving vehicles with the option for use in self-driving vehicles. In this case, there are several driver monitoring features. One typical application for autonomous driving is the detection of human hands on the steering wheel, where ams capacitive presence sensor fits perfectly. The heating plates can also be used for sensing capacity (impedance) between the steering wheel and a human hand. In case of sensing the impedance, it is not that easy to fool the system, e.g.: fooling the system by putting an object, such as a water bottle, on the steering wheel.

Automotive Application - Driver Monitoring

Driver Monitoring

Driver monitoring systems are designed to obtain information about the driver for safety- and comfort- related applications.

Camera-based driver monitoring systems can detect signs of driver drowsiness or driver distraction and trigger the car's safety systems to respond with appropriate acoustic and haptic warnings to ensure driver attentiveness and so increase safety. Beside the safety enhancing aspects, driver monitoring systems can realize comfort-related applications like driver identification and authentication used to adjust automatic settings  and in-car payment.

Various system architectures can be used to realize optical driver monitoring: from 2D-based NCAP and regulation-compliant systems up to more advanced 3D-capable designs like Active Stereo Vision, Structured Light, and Time of Flight (ToF).

Automotive Application - Gesture Sensing

Gesture Sensing

Tomorrow’s automotive interior will be fundamentally different in shape and functionality, as end customers demand greater convenience, safety, and individualization. Car manufacturers around the world are working toward enhancing the overall driving experience for their customers and this includes implementing innovative ways in which the driver and the passengers can interact with the vehicle's systems and settings.

Optical gesture sensing has proven itself to be a superior technology to simplify human-machine interaction in the car and improve safety by enabling the driver to keep their eyes on the road while communicating with the vehicle via gestures . Already today, optical gesture control systems enable applications like starting or ending a phone call, starting or ending the navigation, controlling the sunroof, radio and sound-settings, scrolling through menus, and adjusting the interior lighting. As the technology matures, more and more applications will follow.

With its rich portfolio of illumination and sensing solutions, ams can support various system approaches ranging from proximity-based solutions for simple and static gesture recognition up to highly sophisticated 3D ToF architectures for complex and dynamic gesture recognition.

Automotive Application - Interior Monitoring

Interior Monitoring

With new upcoming occupant-related safety standards and increasing vehicle autonomy, interior monitoring systems are becoming indispensable to gather a sophisticated scene understanding of the vehicle's interior.
 

Focusing on passengers, pets, and objects in the car, interior monitoring systems can enable various safety- and comfort-related applications for  passenger cars and robo-shuttles, like child- and pet-presence detection, adaptive-airbag deployment, unbuckled-occupant detection, people counting and object left-behind detection.  
 

With a wide range of illumination and sensing solutions, ams can address all common 2D and 3D imaging-based system architectures to realize interior-sensing applications.
 

Inductive Motor Control

Inductive Motor Control

Based on the inductive sensor technology, these sensors measure the coupling between an excitation coil (TX) and two receiver coils (RX) via a rotating target. The coils are executed as printed circuit coils and the rotating target is a simple punched metal part. With the correct layout of the coils and the target, both synchronized to the number of pole-pair count of the motor, the IC output is proportional to the electrical angular position within one pole-pair segment with increased resolution and high performance of only 0.3° electrical INL!

Due to its flexibility, easy adaption and low overall system costs, these products act as the perfect resolver replacement and can be used for on-axis as well off-axis applications!

Angle sensing and motor control

Highly accurate, robust and reliable, compact position sensors from ams are an ideal fit for automotive angle and rotary position sensing applications.

ams automotive angle sensors are widely used for sensing the angle of the accelerator and brake pedals, and the position of gear shifters and chassis.

Dedicated rotary position sensors for motor control are also ideal for automotive uses, such as the pump motors in electric power steering and transmission system motors. The number of electric and hybrid electric vehicles on the road is also set to grow at a rapid rate. Here, the ams motor control sensor portfolio offers high accuracy at high rotation speeds, while remaining inherently immune to the external magnetic fields induced by the high currents flowing through the motor.

Automotive Application - LiDAR

LiDAR solutions for autonomous vehicles

The move to equip vehicles with increasingly sophisticated driver assistance systems, and eventually to make the vehicle fully autonomous, requires a combination of object detection and imaging sensors. By combining radar detectors, cameras and optical depth sensing systems such as LiDAR, a vehicle can capture a detailed, real-time view of the space around it, while building in redundancy to protect against the failure of any one sensor.

For LiDAR systems, the VCSEL arrays and VCSEL driver technology from ams provide high-power light sources that operate extremely reliably over a broad temperature range.

Automotive Application - Projection Lighting

Projection Lighting

Micro Lens Array (MLA) projection technology from ams enables automotive manufacturers to implement compact, small-footprint projection lighting which can cast bright and crisp images on to flat surfaces. Featuring inherently extended focal lengths, MLA Projected Lighting devices can cast images on a variety of surfaces and over long focal distances, making them ideal for both exterior body lighting and interior lighting.

Future applications include decorative lighting for cars' exterior and interior, but also safety lighting, such as an additional brake light or back up guide lamp, helping to raise awareness of other traffic participants about actions this vehicle is taking. With upcoming autonomy of cars, this will also become ever more important to show when a vehicle is in autonomous mode.

Automotive Application - Battery

High-precision sensing for automotive battery packs

Electric vehicles need to measure very precisely the traction battery’s state of charge and state of health in order to make an accurate estimate of the vehicle’s range

Shunt resistor-based, zero-offset battery sensing solutions from ams enable automotive battery management systems to make the very accurate current and voltage measurements which are required in this application.
