The integration of IDIADA Spain virtual Proving Ground (ISVPG) within ADAMS/Car offers a new virtual scenario to carry out detailed analysis of durability as well as Comfort & Ride. Moreover, these high resolution roads (modeled as OpenCRG road format) support model development activities through better correlation with experimental tests. This approach helps to reduce the number of real tests and to shorten development process times. At the same time, this data would be prepared for performance testing to support driving simulator and active system development. The objective of this paper is to demonstrate the benefits to use FTire model for Ride and Comfort applications and the use of flexible bodies for better predictions. The availability of this information will depend on the status of the project and the level of maturity of the simulation input data. As a result, different levels of accuracy will be reached according to the existing input data.

The rapid growth of Electric Vehicles (EV’s) and Hybrid Electric Vehicles (HEV’s) has increased the concern that the relative silence of these type of vehicles will result in an increased risk to pedestrian safety. A practical solution to this problem is to add artificial sounds to EV's to aid their detection by pedestrians and other vulnerable road users. Acoustic warning systems for EV’s should increase pedestrian safety and simultaneously produce a small impact on environmental noise levels. This paper shows the main advantage of using a directive acoustic source implemented as a beamforming loudspeaker array in an EV to increase pedestrian safety and control the effect on noise pollution. An example of such a system has been implemented in a Nissan Leaf vehicle and its performance in realistic situations has been assessed.

Active safety systems such as Electronic Stability Control (ESC) have been clearly demonstrated to increase vehicle safety in critical dynamic maneuvers. With such a great potential for reducing road accidents, the ESC system is being more widely fitted all over the world. As a result and in parallel with regulation initiatives, consumer organizations are expanding their assessment capabilities from passive towards active safety. Since 2008, ESC fitment promotion has been the first step for worldwide consumer organizations such as ANCAP (Australia), NASVA (Japan) and Euro NCAP (Europe). However, a major step has now been taken by Euro NCAP with the inclusion of the first active safety test in the overall Euro NCAP safety assessment programme. As of 2011, Euro NCAP performs the so called “Dwell sine” test on all cars that meet the ESC fitment requirement.

This paper presents the results of the suspension development for a hybrid (Bi-fuel) passenger car. An accurate ADAMS/Car model was developed to simulate the vehicle dynamics behavior. Based on the steady state and transient analysis, the required modifications to the suspensions parameters were determined. In addition to the presentation of the suspension synthesis/analysis results, the results of the Ride and Handling subjective and objective tests are also presented.

The active control of suspension geometry has historically been a challenging perspective for chassis teams of worldwide auto makers. Manufacturers and suppliers have offered different solutions, but few succeeded in combining a remarkable improvement on handling performance, low energy consumption, simplicity and low cost. The new and revolutionary approach of AGCS reinvents the possibilities of rear suspension active toe control. This system makes use of the complexity of a rear multi-link suspension, and a clever design layout as to minimise the use of energy. Thanks to an efficient control logic the vehicle handling performance and stability has substantially improved. The system is most successful in controlling vehicle transient situations, mainly originated by aggressive lane change maneuvers at mid-high speeds.
