TOKYO, Japan - Honda has joined other auto makers with the introduction of a low-speed collision prevention system. It's called the City-Brake Active System.A laser 'radar' at the top of the host car's windscreen switches on when the car is traveling less than 30km/h to identify other vehicles or obstructions. Should the driver fail to identify the obstruction the car will be braked.If the system identifies - depending on weather - a high risk of collision it will use audio and visual warnings and if the driver does not react, the car will brake for him.PREVENTING FENDER-BENDERSIt is also intended to protect drivers from accidental acceleration from stationary to 10km/h - perhaps from a car-park slot? - should there be an obstruction within four metres of the front of the vehicle. The driver will receive audio and visual warnings and City-Brake Active will control engine output to restrict progress.City-Brake Active will be introduced on the all-new Honda Jazz which will go on sale later in 2013.Honda says: "Our commitment to safety is embodied by the term ‘Safety for Everyone’ and we will continue to equip cars and motorcycles with the most advanced and effective safety features possible."
