Nissan is developing a safety feature for it’s cars to help avoid colliding with the vehicle in front in the case of a possible sudden brake situation.
In Nissan’s accelerator pedal safety system, a combination of radar sensors connected to a computer system monitors the car’s speed and the distance to the vehicle in front. If the vehicle in front suddenly slows down (like a jam brake situation) or there is any other possibility of a rear-end collision as calculated by the computer system, the gas pedal will automatically rise against the driver’s foot as a signal to step on the brake.
Once the driver lifts his foot off the accelerator pedal, the system does not wait for him to start braking, it automatically kicks in. Of course, the driver’s foot would go ahead and press the brakes anyway.
This makes me think, doesn’t this system require the use of brake-by-wire? Brake-by-wire’s benefits versus safety hazard is still being debated in the industry, though most modern brake-by-wire systems like Mercedes Benz’s Sensotronic Braking Control comes with a manual safety net.
