Nissan will use the SAE 2010 World Congress to show its breadth of engineering development, with the presentation of key technologies that feature in models in the company’s range.
One vehicle demonstrated will be the Infiniti M56X, which debuts a number of innovations, such as the claimed world’s first blind-spot intervention (BSI) system. The BSI is available as part of the car’s M Technology package alongside blind-spot warning (BSW) technology. BSW illuminates an indicator light if another vehicle is detected in the blind spot area. If the driver then uses the turn signal, the indicator flashes and an audible warning sounds.
BSI takes blind-spot technology to the next level. If the vehicle gets close to the lane marker and another vehicle is detected in the blind-spot area, the indicator flashes, an audible warning sounds, and selective braking is applied to one side of the vehicle to help the driver bring the vehicle back to the center of the driving lane. BSI operates regardless of turn-signal usage.
The Infiniti M56X also debuts ECO Pedal, a system that is designed to help drivers achieve better levels of fuel economy. When ECO Pedal is on and the driver puts excess pressure on the accelerator, a pedal push-back control mechanism comes into play to "suggest" a more-efficient driving style.
The driver is also alerted by a light on the dashboard indicating a shade of green relating to how efficiently they are driving. Should the system display an orange light, or flash green, the driver needs to change the level of acceleration input to gain fuel efficiency. Based on Nissan’s internal research data, studies have shown the technology to improve fuel efficiency by up to 10% in most driving conditions.
Work on the vehicle’s refinement has helped create an active noise control system, which blocks unwanted sounds. Unlike some other noise-canceling systems, the Nissan solution goes beyond merely quietening the cabin and focuses more on the sound vibrations and waves. With help from audio systems supplier Bose, advanced sonic technology has been used to eliminate specific sound waves and enhance the sensation of the car’s engine note.
At the other end of the vehicle spectrum and ahead of its launch toward the end of the year, technologies from Nissan’s Leaf electric car—vehicle panels and Li-ion battery technology—will also be available to view. The zero-emissions vehicle seats five passengers and has a range of 100 mi (160 km). Nissan consumer research demonstrates that this range satisfies the daily driving requirements of more than 70% of the world’s consumers who drive cars.
The Leaf is powered by laminated compact lithium-ion batteries producing more than 90 kW, while its electric motor delivers 80 kW. The car’s battery can be charged up to 80% of its full capacity in just under 30 min with a quick charger. Charging at home through a 200-V outlet is estimated to take about 8 h.
