The new braking systems
Much has happened since the ABS (Antilock Braking System) will revolutionize the automotive world . For first time an electronic system was capable of acting beyond the driver, adjusting the brakes to prevent wheel lockup and maintain direction. Since then, this system has been improved leading to new models further insurance: the emergency brake assist system BAS, the electronic braking distributor EBD (EBD) Servotronic steering or brakes. BAS Brake Assist System
In a situation of danger, a sensor detects that we walked quickly and forcefully the brake. At that time additional servo actuated maximizing brake pressure and reducing the distance traveled. Electronic EBV
Variation Brake System (EBD)
Through a sensor, regulating the braking force between the front and rear according to the weight of each, sending more or less pressure to the wheels. Servotronic
A new directional braking system is activated when braking in curves. Cuar1do detects that the wheels on one side turn less on a curve and where it is spinning the wheels braking more than one side to get to a directional effect and compensate for the inertia weight v speed.
THE EBV
EBD (EBD) Especially in front-wheel drive vehicles, the ABS works in conjunction with the electronic distribution of braking force (EBV) which ensures optimum brake pressure at the rear wheels. When you brake hard in front-wheel drive vehicles the rear wheels tend to lose grip, so that the system transmits EBV in which case a lower braking pressure (larger, if often slow) trasero.Con the vehicle axis charge is transferred to the rear wheels brake pressure even higher, resulting in better use of the braking force the rear axle, more effective and more uniform wear of balatas.En emergencies, most drivers make two errors to stop: step on the brake too soft or begin to slow down with caution increasing pressure as the danger approaches. This unnecessarily prolongs the braking distance, because the ABS does not go into action either makes it too tarde.BASServofreno emergency. When the system recognizes an emergency situation that requires a halt to fund immediately applied maximum pressure servo frenado.El consists of two chambers separated by a moving diaphragm and subjected to a constant depression. When pressing the brake pedal opens a solenoid valve that allows air entry in one chamber, the pressure varies in proportion to the freno.Se pedal position sensor incorporates a shift diaphragm that detects any movement of the brake pedal. The received data is transmitted to the control unit of the BAS, which analyzes permanentemente.Esta control unit recognizes any rapid variation, especially in the brake pedal position and identified with an emergency situation. Immediately activates a solenoid valve that lets air into one chamber of the servo, which generates the maximum pressure frenado.Cuando the driver takes his foot off the brake, the control unit reacts immediately closing the valve, assuming intervention ended Brake emergencia.Al be interconnected with the control panels of the ABS, ASR or ESP, as well; as with the electronic equipment of engine and gearbox, the BAS receives information during the march that let in all situations to ensure an optimum adaptation of the braking pressure. This can be done thoroughly braking when braking oportuno.BDCControl Dynamics. Has a function comparable to that of the regulated reaction BAS.ETSSistema electrónicamenteAntes when problems occurred Traction resorted to automatic locking differential (ASD) in which the blocking effect is generated in the disks of the differential or, in the total.Hoy traction these days is entrusted this task to two advanced systems: the electronic traction system (ETS) or non-slip traction system (ASR). The electronic traction system (ETS) ensures maximum traction when starting or when accelerating, even in extreme situations. No involvement in the management system engine brakes are applied selectively on motrices.Al wheels as in the ABS wheel sensors report the speed of them. If one of the driving wheels start spinning in a vacuum, ETS increases the braking pressure on the wheel and brake question instantáneamente.El braking torque generated at the wheel tends to skid is immediately transmitted as a pair of drive to the wheel with better grip. When normalized the torque is no longer applied pressure frenado.De Thus, the wheel is always in the most favorable range of traction and the vehicle retains its trayectoria.Esta intervention on the brakes can be done when starting from a path with a different grip, acting as a blocking diferencial.El EDS (electronic differential lock) is very similar to ETS and, like this, does not intervene in the electronic system motor.TRACSTraction Management Control System (Control traction). Presents a structure and mode of operation similar to the formula EDS.ASR While the ETS to improve traction is to apply the brakes ASR also intervene, if necessary, the engine management system, offering greater stability from start-up speed plus security máxima.Este shows especially on cars with large engine power : in wet or frozen roads, even the most experienced drivers have difficulty managing the throttle as accurately and quickly as does the ASR.Cada wheel has a sensor that records your speed. These data are analyzed in the control unit. If the driver presses the accelerator so hard that the drive wheels begin to spin in vacuum, the ASR show that the motor drive torque is too high. With the electronic throttle it acts on the throttle butterfly in milliseconds, which automatically reduces the throttle (though the driver is stepping on the accelerator). If accused of slipping wheels, braking system also involved a wheel motor or both simultaneously (if the speed exceeds 40 km / h). The ASR uses 2 circuits of regulation: the brake system and engine. Besides the effect of braking slip regulation ABS, ASR prevents the driven wheels to rotate at idle and helps stabilize the vehicle's path regardless of speed when starting and accelerating, cornering, with ice sheets or maneuver bruscamente.DSASistema non-slip works at any speed. This equipment uses the ABS system sensors and engine management to prevent the wheels from turning in vacío.Pero, unlike ASR, does not intervene on the brakes or engine power varies across the choke butterfly but acts on the fuel injection flow. The driver clearly note the operation of the system.
