Hiroshima, Feb 13, 2012 - (JCN Newswire) - Mazda Motor Corporation has developed an advanced safety technology called Smart City Brake Support (SCBS), which helps a driver to avoid a frontal collision when driving at low speeds in the city or in slow traffic. The SCBS system will be available in Mazda's all-new crossover SUV, the Mazda CX-5, to be launched this spring.

The SCBS system uses a laser sensor to detect a vehicle or obstacle in front and automatically reduces the extent of the brake rotor travel to quicken braking operation. If the driver fails to perform any operation to avoid a collision, such as applying the brake, SCBC automatically activates the brakes and reduces the engine output at the

same time. In this way, SCBC helps to avoid collisions or mitigate the damage from rear-end collisions at low speeds, which are the most common accidents with other vehicles. The SCBS system also includes Acceleration Control for Automatic Transmission, which helps avoid unintentional acceleration that could be caused by depressing the accelerator instead of the brake pedal.

Details of functionality

Smart City Brake Support (SCBS)

When driving from approximately 4 - 30km/h, 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 quicken braking when the system calculates that there is a risk of a collision occurring. Next, if the driver fails to perform any avoidance maneuver such as applying the brake, an automatic braking operation is activated. When the speed difference between the driver's car and the vehicle in front is less than 30km/h, the system is designed to avoid, or mitigate the damage from a collision.

Acceleration Control for Automatic Transmission

If a 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 is intensifying its safety-related research and development efforts, aiming for the ultimate goal of realizing an accident-free and safe motorized society. Mazda intends to extend its advanced safety technologies, such as SCBS, to upcoming new models, starting with the Mazda CX-5, to provide all customers with driving pleasure together with outstanding environmental and safety performance.

About Mazda





Mazda Motor Corporation (TSE: 7261) started manufacturing tools in 1929 and soon branched out into production of trucks for commercial use. In the early 1960s, Mazda launched its first passenger car models and began developing rotary engines. Still headquartered in Hiroshima in western Japan, Mazda today ranks as one of Japan's leading automakers, and exports cars to the United States and Europe for over 30 years.
