1、外文翻译 Automotive safety technology is divided into active safety technology and passive safety technology.Now following is a brief vehicle active safety. ABC active body control system ABC system allows cars on the roll, pitch, yaw, beating, and ride height control can be more rapid and precise. Body
2、 roll is small, the wheel camber angle is also small, will be able to better keep the tires perpendicular to the ground contact to improve the adhesion of the tire on the ground in order to take full advantage of the drive tire braking effect. The emergence of ABC to overcome the suspension settings
3、 between comfort and handling the conflict, to maximize the vehicle to reach customers in both of these cars on the ABC system to roll, pitch, yaw, beating and body height control can be more rapid and precise. ABD automatic brake differential Braking system is a new product, its main role is to sho
4、rten the braking distance, and the ABS, EBD, etc. with the application. When the emergency brake, the car will be down nod, the weight of the car forward, while the corresponding vehicle weight borne by the rear wheel will be less severe when the rear wheels lose grip, then the equivalent of only th
5、e front wheel the brake will cause braking distance is too long. The ABD can effectively prevent this, it can detect all the wheel speed discovery of this situation, the corresponding reduction of rear wheel braking force, to make it effective friction with the ground, while adding to the maximum br
6、aking force front wheel to achieve the purpose of shortening the braking distance. ABD is 2 the difference with the ABS, ABS braking in an emergency is to ensure that the wheels are not locking in order to achieve the purpose of safe handling, and can not effectively shorten the braking distance. Th
7、e ABD is the vehicle through the EBD to ensure does not occur in the case of skidding, allowing increased to the maximum braking force in order to effectively shorten the braking distance. ABS anti-lock brake system In the absence of ABS, if the emergency brake locking the tire will generally, after
8、 the locking of the tire and the ground is sliding friction, so the braking distance becomes longer. If the front wheel lock, car steering loss of lateral force, easily deviation； if the rear wheels locked, the rear wheels will lose lateral grip, prone to drift. Especially in the snow surface, when
9、the emergency brake, the more likely the above situation. ABS braking oil pressure by controlling the retractable, to achieve the control wheel locked. Course of their work is actually locking - release - locking - release cycle work processes, so that the vehicle is always in the critical state of
10、locking of the roll gap. ASR acceleration skid control system As the name suggests is to prevent the wheel acceleration skid control system, its purpose is to prevent vehicles, especially high-powered car, at the start, and then accelerated the phenomenon of wheel slip to maintain the stability of t
11、he vehicle driving direction, maintaining good handling and the most appropriate driving force, to have a good driving safety. How it works is not complicated: When the computer detects a wheel slip, it will reduce engine power output from, and put the wheels skid braking, until the normal rotation
12、of the wheel. No matter how 3 advanced the car, that are incompatible with the ground only a few dozen square centimeters large area, that is, the ground area of four tires, if not controlled wheel skid, the car will be out of control. Do not think that only the wheels from locking when the brakes w
13、ill be out of danger, as will be wheel spin when starting problem. BAS Brake Assist System In urgent cases, 90% of car drivers lack decisive step on the brake, brake assist system is designed for this situation, it is the brake pedal from the driver to detect the speed of the vehicle encountered cas
14、e, when the driver in an emergency brake pedal quickly, but the stampede when the power is inadequate, the system will help, and in less than one second of time to the maximum braking force to shorten the braking in an emergency in case of braking distance. DAC Downhill Assist Control driving The tr
15、uth with the same engine brake, the brake system in order to avoid the load is too large, reduce driver burden, down auxiliary control actuator in the sub-location in the L； speed 5-25km / h and open the DAC switch conditions, do not step on the accelerator pedal and brake pedal, downhill assist con
16、trol system can automatically control the speed at the appropriate level. Down the auxiliary control system work automatically when the parking light will light up. DSCVehicle dynamic control system BMW developed the DSC control system integrates the ASC Automatic Stability Control system and traction control system that can slip through the trend appears to choose the driving wheel brake to control the driving wheel slip state, thus corresponding to the vehicle to play stability. In ice and snow, desert or gravel roads,
