Validation of brake control systems is becoming increasingly supported by simulations executed on test benches. Performance and test speed are largely determined by the degree of automation of the tool chain used. Elektronische Fahrwerksysteme GmbH (EFS) shows how it has moved to fully automated test execution and the replacement of its entire tool chain in ongoing operation of ESC testing.
MODEL REQUIREMENTS FOR VIRTUAL VALIDATION
As a result of the diversity of functions and derivatives, as well as efforts to increase efficiency of hardware-in-theloop (HiL) testing for vehicle stability functionalities, test tasks and validation tasks are assigned increasingly to the virtual test drives. The entire working environment of the virtual test drive, in addition to driving dynamics modelling, must also be flexible and highly automatable and fulfil many additional requirements, in order to be capable of handling the fast-growing complexity of virtual validation methods. Here, the development of such requirement validation includes examination and demonstration of how full migration of an existing tool chain for functional brake control system validation, to HiL test rigs in ongoing operation, could be achieved and which motivators were defined by the individual components.
SCOPE ESTIMATE AND POTENTIAL COURSES OF ACTION
The focus on the development starts in 2011 with intensive validation of selected brake control functions, such as the electronic parking brake and central stopping and deceleration management, on HiL test rigs. 1 illustrates the development of the test scope levels. Both staff and test scopes, measured as a number of manoeuvres executable on ESC-HiL, are continually increasing with a slightly exponential character. Test execution, test bench design, and model development, at the start of the review between 2011 and 2014, were heavily characterised by highly specialised function manipulation of the software components to be tested: each test scope for a component is assigned to a single test bench together with an individualised braking system, Restbus driving dynamics model adaptations, and a specialised development partner.

Sound Generation For Enhanced Road Safety
With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.
OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS
Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.
RAPIDO RE-INNOVATES TO CATER TO POST COVID-19 LAST MILE CONNECTIVITY
The rapid pace of urbanisation in the country has witnessed cities expanding and subsuming surrounding villages and smaller towns, evolving into Tier II and III cities.
FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT
Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.
“BYD'S EV STRATEGY TO ENCOMPASS MOST FORMS OF TRANSPORTATION NEEDS IN INDIA”
The country’s electric vehicle (EV) ecosystem is grappling with a plethora of challenges even as it is striving to wriggle itself out of the ‘nascent stage’ tag. In an exclusive chat with Auto Tech Review, Zhang Jie Ketsu, Executive Director, BYD India shares his perspective on the current EV scenario and how the company intends to progress faster in the Indian automotive industry
SAFETY IN ELECTRIC AND AUTONOMOUS CARS – SIMULATION OF COMPLEX CRASH SCENARIOS
Electric and autonomous vehicles allow for novel seating arrangements and packaging strategies, presenting new safety challenges. Physical crash testing must be supplemented with virtual simulation to ensure vehicle safety on shorter development cycles. With its Simcenter Madymo MBS software, Siemens provides improved runtimes and the Active Human model, enabling accurate and rapid occupant safety analysis in complex crash scenarios.
KIA SONET – A MIGHTY OFFERING IN THE COMPACT SUV SEGMENT
It wouldn't be wrong to say that Kia Motors India has taken the Indian market by storm in less than 12 months of its presence in the market.
NISSAN'S NEW DIRECTION: ARIYA ALL-ELECTRIC
Marking a key milestone in Nissan’s transformation strategy, Ariya ticks a lot of boxes highlighting the strengths of the global automotive giant.
BETTER SAFETY WITH EMERGENCY BRAKE ASSIST FOR MOTORCYCLES
Rear-end collisions with a slower vehicle suddenly cutting into the lane and intersection accidents with cross-traffic are among the most frequent motorcycle accident types. Continental is now developing an emergency brake assist, which detects an imminent collision with a vehicle ahead or with an obstacle, warns the rider and supports him during braking
