Mazda pursues ever-higher levels of safety by comprehensively addressing all three elements of the safety equation, i.e., people, vehicles, and the road environment. In particular, we make effective use of vehicle-control technologies yielded by rapid advances in intelligent transport systems. These technologies promote safety by minimizing the effects of driver error in recognition, evaluation, and evasion of hazards. With functions ranging from collision prevention to collision prediction, they represent a vital area of ongoing research, development, and commercialization for Mazda.

On a junction where vehicles approaching from the sides and oncoming vehicles that are obscured by right-turning vehicles can't be seen by the driver or detected using onboard sensors and cameras, the Sideswipe-Preventing Communication System exchanges data with approaching vehicles then alerts the driver to their presence using a display and audible warnings. The system thereby helps to prevent a sideswipe collision.

With this system, a computer monitors inputs received from the accelerator pedal, steering wheel, and brake pedal and uses them to determine the vehicle behavior desired by the driver. The computer also uses data from sensors to determine the extent to which the vehicle's actual behavior differs from the desired behavior. Whenever the calculation results indicate the risk of a skid, the computer effects control over the brakes and engine and actively countersteers by exercising control over an electric power-steering system.
