ABS: Can be installed on any car with hydraulic brakes. It uses a rubber airbag in the valve body. When the brakes are stepped on, the brake fluid pressure is given and filled into the ABS valve body. At this time, the airbag uses the air barrier in the middle to return the pressure, allowing the wheels to avoid the locking point. When the wheel is about to reach the next locking point, the pressure of the brake fluid causes the air bag to act repeatedly, so that it can act 60 to 120 times in one second, which is equivalent to constantly braking and relaxing, which is similar to mechanical "point braking" '. Therefore, the ABS anti-locking system can prevent directional control and wheel sideslip during emergency braking, prevent the wheels from being locked during braking, and prevent the tires from rubbing against the ground at one point, thus increasing friction. The braking efficiency reaches more than 90%, while also reducing braking consumption and extending the service life of brake drums, discs and tires by twice. The anti-skid performance of vehicles equipped with ABS on dry asphalt roads, rainy days, snowy days and other roads respectively. 80%-90%, 30%-10%, 15%-20%
EBD: It can automatically adjust the braking force distribution ratio of the front and rear axles to improve braking efficiency (to a certain extent). can shorten the braking distance), and cooperate with ABS to improve braking stability. When the car is braking, if the four tires adhere to the ground in different conditions, for example, the left wheel adheres to the slippery road, while the right wheel adheres to the dry road. The friction between the four wheels and the ground is different. When braking (the braking force of the four wheels is the same), it is easy to cause slippage, tilting and rollover. The function of EBD is to calculate the speed at high speed at the moment the car is braking. The friction values ??of the four tires caused by different adhesion are then adjusted, and the braking device is adjusted at high speed during movement according to the set program to achieve a match between braking force and friction (traction force) to ensure the stability and stability of the vehicle. Safety. When the wheels are locked under emergency braking, EBD has balanced the effective ground grip of each wheel before ABS action, which can prevent slipping and sideways movement, and actually shorten the braking distance of the car. ABS assist function, which can improve the effectiveness of ABS: EBA understands its braking behavior through the rate at which the driver depresses the brake pedal, and if it detects the braking of the brake pedal. Pressure increases in panic and EBA activates full braking force in milliseconds, much faster than most drivers can move their feet. EBA significantly shortens emergency braking distances and helps prevent stop-and-go situations. When a rear-end collision occurs in traffic, the EBA system relies on a time base to monitor the movement of the brake pedal. Once it detects a sudden increase in the speed of the brake pedal and the driver continues to press the brake pedal vigorously, it will release the stored 180. The hydraulic pressure of the bar applies maximum braking force. As soon as the driver releases the brake pedal, the EBA system switches to standby mode. Emergency Brake Assist significantly shortens the braking distance due to the earlier application of maximum braking force. p>
TCS: Also known as tracking control system, it determines whether the driving wheel is slipping based on the rotational speed of the driving wheel and the transmission wheel. When the former is greater than the latter, it then suppresses the speed of the driving wheel. An anti-skid control system. It operates very similarly to ABS, both using sensors and brake regulators.
When TCS senses wheel slippage, it will first change the engine ignition time through the engine control computer, reduce the engine torque output, or apply brakes on the wheel to prevent the wheel from slipping. If the slippage is severe, it will Controls the engine fuel supply system. When TCS is in use, the gearbox will maintain a higher gear, and when the accelerator is pressed, it will avoid sudden downshifts to avoid more slipping. The biggest feature of TCS is that it uses the computer of the existing ABS system, the transmission speed sensor and the computer that controls the engine and gearbox. Even if the spare tire is replaced, TCS can be applied accurately.
DSC: The function is similar to the TCS and ESP above. Since ESP has been registered as a special trademark, the electronic stability systems developed by other companies have their own names, such as TSC, DSC, and ESP. , VSA, VSC, etc...
