With the all-new compact CX-5 crossover SUV (from this spring in Europe), Mazda will also present the new Smart City Brake Support safety technology (SCBS).

Developed by Mazda Motor Corporation, the SCBS technology is conceived to help avoid a frontal collision when driving at low speeds in the city or in slow traffic.

SCBS

The SCBS mission is to detect a vehicle or obstacle in front of the car and automatically quicken the braking operation and efficiency by reducing the extent of the brake rotor travel. So, if the driver doesn't apply the brake, SCBC automatically activates the brakes while reducing the engine output to help avoid collisions or at least, to mitigate the damage from rear-end collisions at low speeds.

The SCBS system also includes Acceleration Control for Automatic Transmission (only available in the Japanese market currently), which helps avoid unintentional acceleration that could be caused by pushing the accelerator instead of the brake pedal.

How it works

When driving between 4 and 30 km/h (2.5 - 19 mph), a laser sensor mounted at the top of the front windshield glass detects a vehicle or obstacle in front of the car and reduces brake rotor travel to boost braking efficiency when the system determines that there is a risk of a collision.

If the driver fails to perform any avoidance manoeuvre, automatic braking is activated. Should the speed difference between the driver's car and the vehicle in front be under 30km/h (19 mph), the system is designed to avoid, or mitigate the damage from a collision.

In cars equipped with the Acceleration Control for Automatic Transmission function, if the driver accelerates when an obstacle in front has been detected by the SCBS' laser sensor, the system alerts the driver with an alarm sound and an indicator. At the same time, engine output is curbed to stop unintended acceleration.

Mazda says that it intends to extend its advanced safety technologies, such as SCBS, to other upcoming new models. In the meantime, the auto maker reminds the users that the performance of the system may be impacted by road / driving conditions, weather conditions and the state of the vehicle. >>>
