2009 Infiniti FX50

TECHNOLOGY AND SAFETY SYSTEMS

The new Infiniti FX50 offers a wide range of advanced available technology and safety systems, helping reinforce the strong sense of communication between the FX50 and its driver – as well as providing a secure and inviting feel. 

The FX50 comes standard with the unique Infiniti Around View Monitor utilizes four small superwide-angle cameras – mounted on the front, side and rear of the FX50 – to project an all-around view of potential objects on every side of the vehicle, helping reduce blind spots when parking. The system uses advanced image processing to provide a unique “Birds-Eye View” of the vehicle, making it easy for the driver to position the FX50 for parallel parking by simultaneously confirming the exact placement of the front and rear of the vehicle. The system includes front and rear sonar sensors for camera assistance, also displayed in an easily understandable fashion on the display.

The FX50’s standard Intelligent Cruise Control (Full Speed range) system combines the brakes, throttle and laser rangefinder with the cruise control system to automatically maintain a set distance between the FX50 and a vehicle in front of it. FX50’s Intelligent Cruise Control operates in “Full Speed Range” (from 0km/h) hence reducing the driver’s workload in congested traffic as well as smooth long distance travel. The Intelligent Cruise Control assists the driver with acceleration and deceleration actions and stops the FX50 if traffic requires.

Standard on the FX50’s, Intelligent Brake Assist (IBA) system uses the laser rangefinder from the Intelligent Cruise Control’s (ICC) system and analyzes closing speeds to a vehicle ahead to help prevent or reduce damage caused by a rear-end collision. If a forward collision is imminent with the vehicle in front of the FX50 and the driver must take immediate avoidance action, the system sounds a warning to prompt driver action. When a rear-end collision cannot be avoided by the driver’s action, the system activates the brakes to decelerate the vehicle, thereby helping to reduce damage resulting from the collision. IBA can apply up to 0.5g braking force (1.0g is considered close to the maximum possible braking force).

The FX’s enhanced FM platform Zone Body Construction is designed to help protect occupants in a collision by helping to absorb crash energy through use of front and rear crushable zones. In a high-speed frontal collision, for example, the crushable zone crumples while the engine is designed to move under the occupant compartment. This has the effect of expanding the crushable zone, thereby helping to reduce deceleration g-force and simultaneously helping minimize cabin deformation, especially in the lower leg area. In offset impacts, the body construction helps decrease the amount of cabin deformation. Special high-resistance steel is used for light weight and improved strength.

As with all Infiniti vehicles, significant time was spent to ensure excellent passenger safety. The first-generation FX received 5 Stars for all measures in the U.S. National Highway Traffic Safety Administration (NHTSA) New Car Assessment Program (NCAP) testing, and the new second-generation FX is expected to offer similar or better occupant protection.

Other standard safety features found on the FX50 include a seat belt reminder system; airbags for driver and front passenger with front hip-thorax side airbags and front-to-rear curtain airbag for rear passengers. Also standard are 3-point front seat belts with pretensioners and load limiters, front seat Active Head Restraints.

The FX50 also features a breakaway brake pedal and double-wall bulkhead construction to help reduce lower leg injuries and a breakaway construction of the propeller shaft (connected with the engine-drop function). 

The FX50’s standard Tire Pressure Monitoring System (TPMS) uses pressure sensors with transmitters mounted inside each wheel, which transmit data by radio wave to a control module, sending tire pressure information to a center display indicator on the FX50’s information panel. A warning lamp and display indicates when a low tire pressure condition (less than 75 percent of normal pressure) is detected.
