› Electronic Stability Control (ESC) is an active safety system that recognizes unstable driving conditions at the very outset and applies automatic and immediate, corrective action, if necessary.

› Critical Safety system

Chassis & Safety System ExampleElectrical Stability Control System

ESC is the sum of the following functions:ABS Anti-lock Brake SystemEBD Electronic Brake force DistributionTCS Traction Control SystemAYC Active Yaw Control



This is how ESC corrects the situation when a vehic le is under steered:

Interior System examplesMission: Information Management in the Vehicle for Driver & Passengers – a Key to Realize ‘Clean Power’ and ‘Zero Accidents’

We add new functions by providing a connection to the outside world as well as value-added services.

With our intuitive and ergonomic human-machine interface (HMI), we capture commands, prioritize and present information.

Main Requirement and constraints:

PASE Key Localization accuracy (Thatcham



PASE Key LF Antennae

PASE ECU

› PASE Key Localization accuracy (ThatchamRequirement)

› Vehicle shape and material diversity

› Wireless communication robustness

› Response time for Unlock function

› Security: immobilizer function

› PASE Key battery life time

› ECU Low Power Consumption

Advanced Driver Assistance SystemsSome Examples

› Adaptive Cruise Control (ACC): ACC follows the flow of traffic ahead of the vehicle, even if its forward progress is only stop-and-go.

› Blind Spot Detection (BSD): Blind Spot Detection warns the driver when there are vehicles in the blind spot of the side-view mirror.



› Emergency Brake Assistant ( EBA): Emergency Brake Assist detects critical traffic situations and ensures optimum braking

› Lane Departure Warning (LDW): The Lane Departure Warning (LDW) driver assistance system alerts the driver with acoustical or hapticwarnings before his vehicle is about to leave the lane.

Automated Driving SystemsSome Examples

› Traffic Jam Assistant: Braking, starting, and adherence to a safe following distance take place automatically, leaving the driver free to enjoy his or her favorite music, talk on the phone, or chat with passengers.

› Parking Pilot: The vehicle connects with the infrastructure and drives to an assigned parking space completely automatically.



› Highway Chauffeur: If the driver has activated the highway chauffeur feature, he or she can use that time to talk on the phone, check e-mail, or just relax and enjoy the multimedia system.

Platform ApproachAUTOSAR: Technical Overview

ModularityModularity of automotive software elements enables tailoring of software according to the individual requirements of electronic control units and their tasks.

ScalabilityScalability of functions ensures the adaptability of common software modules to different vehicle platforms to prohibit proliferation of software with similar functionality.

TransferabilityTransferability of functions optimizes the use of resources available throughout a vehicle´s electronic architecture.



Re-usabilityRe-usability of functions helps to improve product quality and reliability and to reinforce corporate brand image across product lines.

Standardized interfacesStandardization of functional interfaces across manufacturers and suppliers and standardization of the interfaces between the different SW-Layers is seen as a basis for achieving the technical goals of AUTOSAR.

The figure on the right hand side shows a very condensed view of the AUTOSAR approach. The basic concept is the AUTOSAR Software Component (SW-C).

Agenda




Platform approach4

System integration5





› Number of ECUs is increasing as more and more functions are provided

› Today, Average is 25 ECUs per vehicle, more than 100 ECUs are embedded on some luxury vehicles, as a consequence:

› More network connection needed

› Wiring harness weight is increasing

System Integration


› Wiring harness weight is increasing

› More power consumption

› System Complexity is increasing


› Body Control Modules (BCMs) are central elements of vehicle electronics. They combine several functions in one housing and control practically all the vehicle's electronic basis, comfort and security functions.

› They make classical standard functions such as actuation of lights and windshield wipers possible.

› In addition, Body Control Modules are increasingly also integrating further functions like Passive Start and Entry (PASE) or Tire Pressure Monitoring Systems.

System IntegrationExample


› Thanks to their scalable architecture and AUTOSAR-compatible software modules, they can be freely adapted to satisfy customer requirements and harmonize with a specific vehicle in order to respond to market demands worldwide.
