How Does a Car Braking System Work?

The working principle of a car braking system is to generate significant friction, converting the vehicle's kinetic energy into thermal energy, thereby achieving the braking effect. The components of a car hydraulic braking system are: 1. Control System: Pedal, handbrake. 2. Hydraulic System: Composed of hydraulic fluid, brake pump, and hydraulic lines. 3. Power Assist System: Vacuum booster pump. 4. Electronic Control System: Composed of ABS pump, ABS sensors, and ABS computer. 5. Execution System: Composed of brake calipers, brake pads, and brake discs. Additional Information: 1. A car braking system refers to a series of specialized devices that apply a certain force to specific parts of the car to enforce a certain degree of braking. 2. The functions of the braking system are: to enable a moving car to decelerate or even stop as required by the driver; to keep a parked car stationary under various road conditions; and to maintain a stable speed for a car moving downhill.

What is the braking principle of the handbrake?

The braking principle of the handbrake: For small cars, some handbrakes are located behind the transmission, connected to the driveshaft, where there is a brake disc, similar to a disc brake (though drum brakes also exist). The pulling force is transmitted via a steel cable to achieve parking braking. Below are some precautions for using the handbrake: 1. Mechanical handbrake: Avoid pulling too tightly. For the most common mechanical handbrake, first, avoid pulling it too hard every time you park, especially not pulling it to the limit. Overstretching the metal or keeping it stretched for too long can accelerate deformation, leading to faster wear of the handbrake cable. The correct method is to pull the handbrake until the rear wheels lock, then lift it 1-2 notches further to ensure the car doesn't roll. 2. For automatic transmission cars: Engage the handbrake before shifting to P. For automatic transmission cars equipped with an electronic handbrake, when parking on a slope, always engage the handbrake to secure the car first, then shift the transmission into P to reduce the burden on the transmission and prevent the P lock from jamming, which could make it difficult to disengage.

What are the dates for toll-free holidays on highways?

Highways offer toll-free passage during the Spring Festival, Qingming Festival, Labor Day, and National Day. The free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday. If you enter the highway during a non-free period but exit during the free period, you qualify for toll-free passage. Conversely, if you enter during the free period but exit during a non-free period, you do not qualify for toll-free passage. Relevant information about highway toll-free policies is as follows: 1. Introduction: The holiday toll-free policy refers to the exemption of tolls for small passenger vehicles during major holidays. 2. Specific notice: On September 24, 2020, Sun Wenjian, spokesperson for the Ministry of Transport, stated that during the 2020 National Day and Mid-Autumn Festival holidays, toll roads nationwide would continue to exempt small passenger vehicles from tolls. The specific free period was from 00:00 on October 1 to 24:00 on October 8.

What is the penalty for driving without shoes?

Driving without shoes can result in penalties. Below is the latest traffic regulation regarding barefoot driving: 1. Penalty for barefoot driving: The new traffic regulations explicitly mention that 'driving a motor vehicle while engaging in activities that hinder safe driving, such as making or answering handheld phone calls, will result in a 2-point deduction.' The word 'such as' in this regulation includes driving in high heels, slippers, or barefoot. 2. Impact on driving safety: When operating a motor vehicle, the driver needs to promptly and accurately control the accelerator, brake, and clutch pedals. Driving barefoot can lead to several issues: first, it may cause toe cramps, with potentially severe consequences; second, the soles of the feet are prone to sweating, making the pedals slippery and further compromising driving safety; third, driving barefoot is uncivilized. 3. Correct attitude: Motor vehicle drivers must adopt the right attitude, fully understand the dangers of 'barefoot driving,' cultivate good habits of safe and civilized driving, consciously eliminate the bad habit of 'barefoot driving,' and ensure driving safety.

Can I switch to C2 after failing C1 Subject 3 four times?

C1 Subject 3 cannot be changed to C2 after failing four times, and the test content cannot be arbitrarily changed during the examination period; however, after failing five times, you need to retake Subject 1, at which point you can switch to the C2 test. The C1 test subjects include four items: traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving knowledge. C1 driver's license test passing standards: Traffic regulations and related knowledge (Subject 1) - Written test, full score is 100, 90 or above is passing. Field driving (Subject 2) - On-site, actual vehicle. The minimum requirement is 80 points, below 80 is failing. Road driving (Subject 3) - Highway or simulated site, actual vehicle. Full score is 100, must achieve 90 or above to pass. Safe and civilized driving knowledge - Written test, questions mainly in the form of cases, pictures, animations, etc., question types include true/false, single-choice, and multiple-choice, totaling 50 questions, full score is 100, 90 is passing.

What is the Function of Automotive Chips?

When the car key is turned in the ignition switch, the Engine Control Unit (ECU) in the vehicle sends an encrypted electronic code signal to the chip inside the car key. The vehicle will only start if the ECU unit receives and recognizes the correct anti-theft coded signal. Therefore, even a simple car key without any buttons can activate and unlock the vehicle's anti-theft system through the internal chip encoding. Below is more related information: Chip Function: Car keys with chips require specialized original factory matching equipment for programming. In the automotive field, these chips are referred to as magnetically coupled transponder systems. Essentially, these systems operate passively. The chip itself does not need a constant power supply and thus does not require continuous electricity. It only needs to be within the range of electromagnetic waves at a frequency of 125kHz. Under these electromagnetic waves, the chip generates the pre-set coded signal, typically within a range of 1 cm to 15 cm. Since this is a radio frequency, it can penetrate materials, allowing the chip to be concealed within a plastic or rubber key head without being visible externally. The working principle of key recognition in most automotive anti-theft system chips is fundamentally similar. When a car key with a chip is inserted into the ignition lock and turned to the "On" or "Run" position, the induction coil installed around the ignition lock emits an electromagnetic wave. The electromagnetic wave's energy causes the electronic chip in the key to generate and transmit the coded signal.
