Driving is a highly complex activity which requires the driver's full attention. Presently, the human factor is related to 90% [1] of accidents and driver distraction is one of the principle causes. The objective of this project was to create a semi-autonomous system for testing with somnolent drivers. Our system is comprised of a GPS which checks position and velocity of the car continuously, a robot which decides with data from the CAN and GPS if the vehicle is being driven properly and an actuator on the brakes and the engine to stop the car. The robot will monitor these parameters continuously in order to take control of the car if it detects that the vehicle is not being properly driven in order to avoid a possible accident. This device will be on standby. To do this, it was necessary to create a system which allows the driver to handle the car without any influence, but when it detects driving errors can stop the car to put it in a safe state. The system developed in the project enables testing with drowsy drivers to be carried out when there are possibilities of loss of control of the vehicle. It can also be used to increase the safety of test track facilities or other control applications outside the automobile industry, in which safety is fundamental. Copyright © 2011 SAE International.

Worldwide, 1.2 million people die in road crashes yearly; 43,000 in Europe alone. This implies a cost to European society of approximately 160 billion euros, and takes up 10% of all healthcare resources. To reduce these rates, safety technologies have been developed which help to minimize the severity of injuries to vehicle occupants. However, studies have shown that most deaths due to road accidents occur in the time between the accident and the arrival of medical care. Therefore, a fast and efficient rescue operation would significantly increase the injured person's probability of survival. The aim of this project was to define the On-Board Unit (OBU) hardware and software installed in all modern vehicles which could request medical and technical support after a road accident. This device, based on the information from the vehicle sensors, automatically decides whether the car has suffered a road accident or not, the severity of the accident and the kind of accident (impact area). Two kinds of communications were set up in parallel: the first one was an automatic call between the Service Answering Point and the vehicle and the another was the sending of a text message in order to give more detailed information about aspects related to the accident configuration, the vehicle and occupants' state after the impact, the road features and the weather conditions at the site of the accident. Apart from the design of this system, a protocol to test this kind of device was defined. This procedure is based on the accelerations and the rotation suffered by the vehicle due to the collision. Besides providing the accident location, the value of this system compared to other eCall devices is a greater amount of information which allows emergency services to arrive in less time with the suitable tools to properly treat the injured.

Driven by the will to gain further know-how and experience in the field of electric vehicles, and to demonstrate IDIADA's engineering capability, IDIADA decided to convert an existing light commercial vehicle, a Nissan Cabstar, into a fully electric vehicle. The brake department of Applus+ IDIADA investigated and developed different concepts of Regenerative Braking Systems (RBS) for this Electric Vehicle project, all of which based on the existing braking system, but with extended sensors. Thanks to their developments and technologies, Applus+ IDIADA succeeded in demonstrating the potential of electric vehicles. This presentation, with focus on the development and integration of the concept, aims at giving a brief overview on the results achieved so far. Based on the investigation and testing of the conventional braking system, several simulations with different concepts and control logics result in the best possible compromise between costs and system efficiency, allowing this concept an optimal performance. Furthermore, this presentation will deal with the application of the concept to the vehicle, e.g. calibration and validation of the concept when integrated into the vehicle.
