What is electronic stability control?

Reporters visited the 2007 North American International Auto Show to see, automotive safety systems continue to upgrade and improve function, is the major automobile manufacturers diligently pursued. Only from the braking system of active safety technology development, the following ABS (Antilock Braking System) as standard cars outside, EPB (electronic parking brake), ESC (electronic stability control system) has also been a large scale in used on the vehicle; especially the ESC, the United States Federal Security Agency announced this year for North America in the new car must be equipped with devices.
    Currently, the car can match the global electronic stability control system, one of the two parts manufacturer Bosch, second, TRW, but the former call this system ESP, the latter statement by the U.S. Federal Security Agency called the ESC. So, mounted on the vehicle ESC system effectiveness of any security of magic?
January 10, reporters were invited to TRW Automotive Group North American winter test track, in a variety of flat road and drive on icy ramp installation with TRW's ESC system produced four models, the system automatically firsthand instability of the body to correct the super-safe protection.
Electronic stability control (ElectronicStabilityControl, referred to as ESC), is an auxiliary driving control of the vehicle's active safety technology that can automatically correct the instability of the body, help prevent accidents. ESC application of advanced sensor technology to determine the driver's intended direction of travel, the vehicle began to deviate from the road, the system starts interventions, the implementation of one or more wheel braking force to reduce the engine valve intervention, to guide the vehicle back to the correct line .
According to the 2004 fall release of the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety study reports, ESC unit in the United States each year could save 7,000 lives and prevent 56% of single-vehicle rollover car accident. Studies have shown that, ESC technology to prevent accidents or reduce the severity of the accident have significant secondary effects. For this reason, ESC is the 2006 edition of all Audi, Nissan, Infiniti, Mercedes, Porsche, Chrysler SUV, the 2006 edition of all the standard; Cadillac, Jaguar, Land Rover, Lexus , Toyota, Volkswagen, Volvo regarded ESC as optional equipment on all models; ESC after 2006 will become standard on all Honda models, General Motors has announced that starting in 2010, the ESC as standard.
ESC technology as the main development and production company, TRW's ESC system on the basis of the ABS system, traction control and yaw stability function. The system can monitor two aspects of information, one vehicle wheel speed, inertia, yaw acceleration; the second is through the driver's steering input, throttle and master cylinder pressure, and then selectively implement one or more tires braking force to help reduce the risk of the driver lost control. TRW is the world's best-selling 2006, the 40 passenger cars equipped with ESC, ESC of its latest generation of products --- EBC450 (passenger cars) and 455 (light trucks and SUV use) for a variety of vehicle types. TRW Automotive's chief engineer of electronic braking systems, said Thomas told reporters, TRW's ESC system consists of the standard model of inertia (yaw) sensors, angle sensors, wheel speed sensors and electro-hydraulic control unit (E Juan HCU), the control unit installed on the engine side, to receive information through a variety of sensors, automatic processing of information by the sensor on the wheel braking effect produced, and the vehicle driving direction via the steering wheel, the intensity control.
