Advanced Driver Assist Systems (ADAS)

Improving Driver Awareness & Safety

Advanced Driver Assistance Systems (ADAS) continue evolving to deliver not only improved passenger experience and comfort, but provide optimum and safety to the driver. Enabling better situational awareness and control to make driving easier and safer, ADAS technology using FPGA/SoCs and automotive sensors can be based upon systems local to the car, i.e. “vehicle resident systems” like vision/camera systems, sensor technology, or on smart, interconnected networks as in the case of vehicle-to-vehicle (V2V), or vehicle-to-infrastructure (V2I) systems, jointly known as V2X systems.

V2X communications use on-board dedicated short-range radio communication devices to transmit safety related messages about a vehicle's speed, heading, brake status, vehicle size, etc. to other vehicles and receive the same information about other vehicles from these messages. Using multi-hops to transmit messages through other nodes, the V2X network can communicate over long distances. This longer detection distance and ability to “see” around corners or through other vehicles helps V2X-equipped vehicles perceive some threats sooner than sensors, cameras, or radar can, and warn their drivers accordingly.

 

In conjunction with V2I, the potential safety advantages of a wide-scale implementation are enormous. Potential V2I safety applications include:

  • Red Light Violation Warning
  • Curve Speed Warning
  • Stop Sign Gap Assist
  • Reduced Speed Zone Warning
  • Spot Weather Information Warning
  • Stop Sign Violation Warning
  • Railroad Crossing Violation Warning
  • Oversize Vehicle Warning

Benefits of Microsemi FPGAs in ADAS

Microsemi SoC FPGAs and FPGAs provide core data acquisition, processing and display functions while providing industry’s best reliability and security in small footprint packages crucial for building differentiated, secure and reliable advanced driver assist systems.

Data Acquisition and Display

Support for various communications interfaces for capturing data like Camera, Radar etc. These are available as hard or soft IPs. Customization of sensor interface as per design is supported.

Data Processing – Ideal for hardware co-processor

Microsemi FPGAs offer support for complex algorithms required for multi sensor input, image processing at high speeds. FPGAs offer crucial advantage over DSPs in providing parallel processing, enabling faster responses to potential hazards.

Power Consumption

Comparable or lower power consumption to comparable ASSP based solutions for complex processing in multi input and output interfaces system.

Smaller System Size

Microsemi FPGA do not require any external configuration memory and thereby provide real-estate advantage in space restricted applications. This allows for more features to be integrated into a single device.

Reliability and Security

Microsemi FPGA offers immunity against environment factors leading to single event upsets. SEU immunity is paramount in achieving ZERO FIT rate and insurance against potential application failure. Microsemi data and design security modules provide key differentiation by protecting automotive OEMs “secret sauce.“

Benefits of Microsemi FPGAs in Vehicle Connectivity

Microsemi offers best-in-class security for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. Among the available security services, Microsemi offers the most effective authentication feature when an SRAM based physically unclonable function (PUF) is used to compute the private key for identifying a device. Also critical is the use of a public key infrastructure (PKI) for distributing and ensuring associated public keys are authentic.

Microsemi offers secure communications infrastructure for vehicle connectivity. With Microsemi’s advanced data and design security features, messaging between two sources is protected against tamper and corruption and root-of-trust assures source of the message. Secure communications involve multiple key authentications for simultaneous and serial interactions. Microsemi offers dedicated hardware processing engine for faster and reliable key authentication offloading the system controller.

  • Tamper Protection and Detection – deterring and detecting physical attacks on a device
  • Zeroization - used to erase all sensitive data when a tamper event is detected
  • Pass-through license- for CRI patented DPA protection for securing data in transit or at rest
  • Physically Unclonable Function (PUF) based on “Biometric Signature” of the device forms the basis for secure communications
  • PKI – based infrastructure for device authentication

Sensor Interface ICs for Automotive

Microsemi has been shipping automotive interface ICs in volume since 2010, delivering precision analog front end (AFE) custom products for pedals, steering and active suspension, as well as MCU-based motion measurement and sensor interface ICs for linear and angular applications. 


Microsemi’s automotive sensor interface microcontroller portfolio can be used flexibly as position, rotary and angular sensors. The inductive sensor ICs can also be applied as linear variable differential transformer (LVDTs) to measure linear motion or displacement (position).   

The LX3301A and LX3302 are the first members of Microsemi’s advanced sensor interface IC family which serve a variety of primary systems including:

Exterior sensors

  • Power mirrors
  • Suspension (active suspension monitoring)Automotive Sensor Diagram | Microsemi
  • Steering (torque measurement, power assist)


Drive Train Sensors

  • Anti-lock brakes (axle rotation, brake assist)
  • Rear differential (gear speed)
  • Transmission (gear position, shift position)
  • Engine (throttle position, shaft position)
  • Fuel level sensor
  • Mass air flow sensor
  • Radiator air-flow control


Interior Sensors

  • Brake position
  • Throttle position
  • Seat position


Global shipments of new light vehicles are projected grow from nearly 85 million in 2014 to 110 million by 2020, according to industry estimates. Sensors are essential components in the feedback loop of any control system. While current cars average 60-100 on-board sensors, this number is projected to potentially more than double as cars become increasingly “smart” and connected. This translates to a projected 22 billion sensors used on-board vehicles by 2020.
