Valeo, a manufacturer of integrated systems for cars and trucks, has developed three detection systems combining 3D camera, sensor and radar technologies, that improves road safety. Valeo has also unveiled a new technology that transforms lighting and signaling systems.
The multi-camera system provides total visibility of the vehicle's immediate environment so that the driver can maneuver easily and safely. Five miniature digital cameras scan the area around the car, transmitting their data to a control unit that prepares and optimizes the images before they are displayed on the color navigation screen. The precision of the air-conditioning saves energy through the close management of the compressor, contributing to reduced fuel consumption and CO2 emissions.
A reversing camera is coupled with the ultrasonic park assist sensors to provide an image of the area behind the car. Two other cameras are installed on the left and right ends of the front bumper, enabling the driver to view pedestrians, cyclists or other vehicles arriving at a low-visibility intersection or when exiting a parking lot. This system is being introduced on the new Land Rover Range Rover, Range Rover Sport and Discovery and on the new BMW 5 Series, Gran Turismo. During 2010, four more models will be equipped with this feature. It is already available in the US on the Lincoln MKT and MKZ, Ford Fusion and Taurus, and the Mercury Milan.
Valeo's 3D-effect technology, used in the front and rear position lamps, adds substantial depth to the perceived image, despite being only 25mm thick. It is based on the principle of the multiple reflection of light from LEDs (Light Emitting Diodes) and opens up significant new styling possibilities. The company has equipped the D09 concept car with this technology.
The delicate appearance of the rear lamp is improved by a trompe-l'oeil effect. The first stage involved the creation of computer-generated animated images, followed by the fine-tuning of appearance details on a mock-up. The use of LEDs in the lighting system reduces electric consumption, since these light sources require far less power than conventional lamps. A traditional incandescent system requires total lighting and signaling power of around 160W, generating CO2 emissions of over 5 g/km, whereas LEDs cut CO2 emissions to 1.7g/km, corresponding to estimated fuel savings of 0.2 l/100 km on average.
Valeo, an independent industrial Group, focuses on the design, production and sale of components, integrated systems and modules for cars and trucks.
