Difference between anti-lock ABS and SBAS
As the automotive industry continues to evolve, safety is increasingly becoming an important standard for people buying cars. In order to cater to and meet consumer demand for safety performance, manufacturers are also sparing no effort to strengthen the safety performance of their products. Various safety concepts such as SABS and ABS are emerging in an endless stream. Some SUV manufacturers often recommend SABS as an important safety device to consumers in promoting the safety performance of their products and modify them with wonderful words to enable consumers to establish SABS's advanced technology and effective safety awareness , In order to better product sales. As time passes, when products equipped with ABS are introduced, some consumers take it for granted that ABS is worse than SABS, SABS is a super ABS, an upgrade of ABS, and even think that an economical SUV is equipped with SABS. The number of consumers based on this understanding is still quite small. In fact, ABS is the standard safety device commonly used in the world, and SABS is only its initial version, and more common in low-end automotive products. ABS, the Chinese name is "anti-lock braking system" is based on the conventional braking device based on improved technology. ABS working principle is to rely on the speed sensor mounted on the wheel and the body speed sensor, through the computer to control the braking force; emergency braking, once found a wheel lock, the computer immediately ordered the pressure regulator to the wheel Brake cylinder to reduce pressure, so that the wheels resume rotation; ABS work process is actually "lock - release - lock - release" of the cycle of work, the car tire is always in the critical state of locking intermittent rolling state, Can effectively overcome the emergency braking "deviation, side slip, drift tail" and so on, to prevent the body out of control. ABS mechanical, electronic Two kinds of electronic ABS is designed according to different models, its installation requires professional skills; mechanical ABS versatility, as long as the hydraulic brake device can be used in vehicles. Electronic ABS large size, high cost; In contrast, mechanical ABS smaller size, less space, to be more economical and practical. ABS control channel can be divided into four-channel type, three-channel type, two-channel type, a channel type four, three-channel ABS is widely used in cars, light trucks widely used a channel type. SABS, the Chinese called "load-sensing proportional valve", in essence, SABS is just a set of hydraulic machinery; Sensory valve role is to ensure that the appropriate proportion of the front and rear wheel load during driving and to ensure that the car after the emergency brake The wheel is not locked. Sensored proportional valve changes the distance between the body and the axle (external force) to change the spring preload, with the increase of vehicle load, accordingly adjusted so that under any load conditions can be an approximation Ideal braking force distribution. It is installed in the brake master cylinder and rear wheel cylinder between the brake cylinder, the shell, plunger, valves, springs and other components. Shell into the oil hole and brake master cylinder oil hole connected to the oil hole and the wheel brake cylinder connected. When the external force is small, the load-sensing proportional valve plunger is pushed to the right under the spring preload force, the two holes are connected, the master cylinder and the sub-pump pressure equal. When the external force is greater than the spring preload, forcing the plunger to the left, so that the plunger and the valve contact and close the valve, cut off the master cylinder to the channel of the pump; if the external force pressure continues to increase, will make the column Plug right, the plunger and the valve from contact, the valve has been opened, the master cylinder and the sub-pump again. This proportional valve repeated action to make the hydraulic pump constantly adjusted, which is constantly adjusted rear wheel brake force. SABS common in some trucks and seifu, Landwind, ZTE and some other low-grade off-road vehicles. Most cars are now fitted with ABS, but pickup trucks and light passenger cars are also less equipped with ABS. Some pickup manufacturers introduce Sensored Proportional Valves (SABS) as an anti-lock braking system (ABS). According to maintenance experts, this is a misleading consumer. Sensory proportional valve is not ABS, ABS can not be replaced. National standards GB13594 on the ABS have a clear, ABS is a mechanical and electrical integration of parts, consisting of the following components: one or several sensors; one or several controllers and one or several regulators. Sensored proportional valves (SABS) are just mechanical parts and have no sensors or controls. General sense of the proportional valve (SABS) costs only 200 yuan. However, the easiest one-channel ABS sensor cost is more than 1,600 yuan. Therefore, the load-sensing proportional valve is definitely not equal to ABS. Judging from the work effect of both, ABS has the advantages of effectively maintaining the stability of steering control during emergency braking, reducing the vehicle's floating and skating phenomena, and reducing the tire wear. Therefore, whether it is no-load or full-load, Or dry pavement, ABS can effectively play a protective role, as passengers and drivers, "effective bodyguards"; and SABS only in full load or dry pavement conditions can be more effectively prevent the occurrence of side slip, the ice or snow on the road or empty In the case of the basic failure. In comparison, cars with ABS are much safer than those with SABS. At present, ABS has become the standard device for automobiles. Over 75% of the cars produced in the world use ABS, and most economical cars are also equipped with ABS. The SABS is a large-scale application of some trucks and some economical SUV. However, it is a surprise that this year's Beijing International Auto Show debut Jeep2500 version added ABS + EBD (electronic brake force distribution) device, which is the first Chinese economy SUV models equipped with ABS models, insiders evaluation, there May lead to a new revolution in economic SUV.
