offers both laser-based and radar-based systems. Brake assist with preview function anticipates the need to apply emergency braking and pre-pressurize the brake system to help improve brake response. Intelligent brake assist (IBA) with forwarding emergency braking (FEB) (on QX80) uses radar to monitor approaching speed to the vehicle ahead, helping detect an imminent collision. It provides a two-stage warning to alert the driver, and if the driver takes no action, the system automatically engages the brakes to mitigate the collision speed and impact. A predictive forward collision warning system warns the driver of risks that may be obscured from the driver's view. It senses the relative velocity and distance of a vehicle directly ahead, as well as a vehicle traveling in front of the preceding one. The forward emergency braking system judges that deceleration is required, it alerts the driver using both a screen display and sound, then generates a force that pushes the accelerator pedal up and applies partial braking to assist the driver in slowing the vehicle down. When the system judges that there is the possibility of a collision, it will automatically apply harder braking to help avoid one. Nissan has been under investigation for collision avoidance systems on late-model Rogue models that allegedly brake the vehicles for no reason, according to the US National Highway Traffic Safety Administration (NHTSA). , Nissan considered the issue strictly as a "performance update" by issuing technical service bulletins—at least three since January 2019—that pertain to reprogramming the radar control unit, according to the agency. At least 553,860 cars are potentially affected from the 2017 and 2018 model years. Subaru Subaru's system, branded "EyeSight", was announced in May 2008 using stereo camera technology to detect pedestrians and bicyclists. As initially announced, EyeSight enabled pre-collision braking control and adaptive cruise control at all speeds. It was rolled out in Japan to selected models in 2010; in Australia in 2011; and in North America in 2012 for the 2013 model year Legacy and Outback models. An alarm is used to warn the driver of a potential collision hazard in the pre-collision system. The pre-collision braking control was upgraded in 2010 to allow the vehicle to stop automatically if the speed difference between the EyeSight-equipped vehicle and the object in front is less than and the driver takes no action to slow down or stop. Above , the vehicle will reduce its speed automatically.
