The electronic handbrake is a technology that realizes parking brake by electronic control. The working principle is the same as that of the mechanical handbrake, which is controlled by the friction between the brake disc and the brake pad to control the parking brake, but the control mode has changed from the previous mechanical handbrake lever to the electronic button.
In fact, the electronic handbrake is not a new product for now! From high-end cars to mid-end car electronic handbrakes have begun to spread slowly. This has also become a selling point for cars.
So what are the advantages of electronic handbrakes compared to traditional handbrakes? Where is the difference?
Ordinary handbrakes, we know that most of them use steel wire to connect to the rear wheel brake, similar to the drum brake (of course, the separate disc parking brake), and then the tension is transmitted to the brake control through the wire wire to realize the parking system. move.
Traditional system handbrakes have many advantages, such as workability is very reliable, unless the "gate line" collapses, of course, this is a joke. Compared with traditional handbrakes, there are driving feelings. Many friends have modified cars to drift, and handbrakes are drifting learning. You must remember the plots in many movies. There are many sports cars that still retain the mechanical handbrake configuration to increase the driving pleasure of the car. Of course, there are a lot of inconveniences in using the electronic handbrake after using the ordinary handbrake. For example, when the slope starts, the driver may unnaturally touch the ordinary handbrake.
The structure of the electronic handbrake does not have any essential difference from the ordinary handbrake. Simply speaking, it only turns the original handbrake lever into an integrated operation switch based on the original mechanical handbrake, adding a small control module and a Execute the motor only. Said that most people first think of the reliability of the electronic handbrake. After all, it is different from the mechanical handbrake. In fact, the owner can rest assured that the electronic handbrake is more reliable than the ordinary handbrake, and the braking force generated by the electronic handbrake. It is bigger than an ordinary handbrake. It is more convenient to operate the electronic handbrake, especially for the women with less strength, there are many women who can't do anything with the mechanical hand brake, not the hand brake is not in place, it is more difficult to loose the hand brake. I believe that many female car owners have had similar experience. After the men opened the car, the hand brakes were pulled high. When they went to drive, they had to use their hands to send the handbrake.
The external electronic handbrake saves more space than the ordinary handbrake, and the space at the central armrest box is more released (the handbrake is generally near the middle armrest box), and the sensory space becomes larger. The biggest part of the electronic handbrake is the AUTOHOLD automatic parking function. The sensor provides the accurate parking force through the sensor. At the start, the parking control unit passes the sensor, the accelerator pedal sensor and other signals through the calculation, when the driving force The parking brake is automatically released when the resistance is greater than the driving resistance, so that the car can start smoothly. For comrades who often forget to send a handbrake or a handbrake, the electronic handbrake can be said to be welfare. Of course, the electronic handbrake is not without its disadvantages. When the battery is dead, it needs to be powered to release the handbrake. Generally, the battery can't be started without the electric car, but the car must not be dragged and the handbrake must be released.
The handbrake also has an auxiliary safety function, that is, when the brake is lost or a larger braking force is required, pulling the handbrake to increase the braking force is also a means of life-saving. For the mechanical handbrake, this is certainly no problem, but for the electronic handbrake Said that many people will have doubts.
In fact, there is no need to suspect that such a problem has long been thought of at the beginning of the design. Although the handbrake is changed to an electronic type, the button is still effective and the braking force is greater in an emergency.
The emergence of electronic handbrakes can save a lot of parts of traditional handbrakes. Although the traditional hand brake parts and the electronic hand brake assembly do not necessarily have an advantage in price, the space saved can be more useful; the entire electronic hand brake work module can be applied to most models, thereby reducing production costs. This technology is popularized on lower-level models.
Why we recommend IPhone 6S Battery With TI IC (Texas Instruments ) rather than ZY/ZW?
1. TI IC is original method for iPhone battery .
2. Charging more faster, less fever heat to save battery life.
3. Accurate battery power monitorin
4. Keep stable performance and controlable temperture
5. The battery with TI IC more safe, charge more faster, lasts longer life.
