ABS Anti-lock Braking System Usage: Through sensors installed on the wheels, signals indicating that the wheels are about to lock are sent. The controller then instructs the regulator to reduce the hydraulic pressure in the wheel's brake cylinder, decreasing the braking torque. After a certain period, the original hydraulic pressure is restored. This cycle repeats continuously (up to 5 to 10 times per second), ensuring the wheels remain in a rotating state while maintaining significant braking torque. How ABS Works: During braking, ABS quickly determines the locking state of each wheel based on speed signals from the wheel speed sensors. It closes the normally open input solenoid valve for the wheel that is beginning to lock, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to drop rapidly as it connects directly to the brake fluid reservoir, preventing the wheel from fully locking due to excessive braking force. This keeps the braking state at the optimal point (with a slip rate S of 20%), achieving the best braking effect and ensuring the highest level of driving safety.

Can a C2 license holder drive a semi-automatic transmission car?

C2 license holders can drive semi-automatic transmission cars. Below is relevant information about C2 driver's licenses and gear restrictions: 1. Introduction: The C2 driver's license is a type of driving permit that only allows the holder to drive small and micro automatic transmission passenger vehicles, as well as light and micro automatic transmission cargo vehicles. On May 10, 2021, the Ministry of Public Security held a press conference to announce 12 convenience measures under the "I Do Practical Things for the People" initiative to deepen the reform of public security traffic management "simplification, decentralization, and optimization of services." The most notable highlight was the pilot implementation of electronic motor vehicle driver's licenses. 2. Proper Use of Gear Restrictions: Many automatic transmission vehicles are equipped with "gear restrictions," such as "1," "2," "3," "4," etc. These functions limit the timing of gear shifts in automatic transmissions, which is beneficial for the output of engine power and torque. For example, when using "Restriction Gear 1," the automatic transmission will not shift to a higher gear as the engine speed and vehicle speed increase. When using "Restriction Gear 2," the automatic transmission can only switch between gears 1 and 2, and so on for the other gears.

Is a B2 driver's license exempt from review if there are no demerit points?

B2 driver's license can be exempt from review if there are no demerit points. The annual review items are for drivers who have demerit points within the B2 driver's license scoring cycle; if the B2 driver's license has no demerit points, there is no need to participate in the review. Below is relevant information regarding the annual review of B2 driver's license: 1. B2 driver's license annual review process: Most local vehicle management offices have self-service terminals for processing driver's license annual reviews, but if there is no self-service terminal, drivers need to queue at the counter for processing. 2. Types of annual review items after B2 driver's license receives demerit points: In the new regulations for B2 driver's license annual review, there are corresponding requirements for different demerit point situations. (1) If the demerit points on the driver's license do not exceed 12 points: Only need to participate in the above three annual review items. (2) If the demerit points on the driver's license reach 12 points but less than 24 points: When the demerit points reach 12, the driver's license will be revoked. In addition to participating in the annual review, the driver must also retake the subject one test, and the driver's license can only be restored after passing subject one. (3) If the demerit points on the driver's license reach 24 points: After reaching 24 demerit points, the driver's license will also be revoked, and the driver must participate in the annual review and retake subject one and subject three. (4) Special circumstances: The annual review time for the driver's license is thirty days before the end of the scoring cycle, and even if the annual review time is exceeded but not more than one year, the annual review can still be conducted. However, if the driver fails to participate in the annual review for three consecutive scoring cycles with demerit points, the driver's license will be revoked.

How Often Should Car Wiper Blades Be Replaced?

How often car wiper blades should be replaced depends on usage conditions and the quality of the wiper blades, rather than being strictly time-based. Generally, it is recommended to replace them once a year. However, if the wiper blades still perform well and show no signs of aging, replacement may not be necessary. The key factor is the condition of the wiper blades themselves. If there is noticeable streaking or incomplete wiping during use, they should be replaced. Car wiper usage tips: 1. Dirty wiper blades shorten lifespan: If the wiper blades themselves are dirty, gaps may form during use, potentially wearing away the lubricating graphite. This affects performance, increases resistance during operation, and over time, shortens the lifespan of the wiper rubber. 2. Dry wiping damages glass: Using wipers on a dry windshield can harm both the wiper blades and the glass itself. Scratches on the windshield may impair visibility while driving, compromising safety. Always ensure the windshield is wet before activating the wipers. 3. Regular maintenance is essential: Routine care for wiper blades can extend their lifespan and improve performance, ensuring clear visibility for the driver. Cleaning the blades periodically helps maintain their effectiveness.

What is the Correct Way to Apply Brakes?

The correct way to apply brakes includes gently pressing the brakes over a long distance, emergency braking, and braking when stopping. Below is relevant information about braking: 1. Introduction: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking involves fixing a wheel or disc on the machine's high-speed shaft and installing corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force. The brake device is a mechanical braking mechanism that slows down the speed, also known as a decelerator. 2. Purpose: To reduce speed or bring the vehicle to a stop. The principle of braking is to convert the vehicle's kinetic energy into heat energy for dissipation, with the kinetic energy originating from the power provided by the engine, which requires fuel combustion to perform work.

How many years can a National IV emission standard vehicle be driven?

As long as the vehicle is in good condition, a National IV standard vehicle can be driven indefinitely. However, some cities may impose driving restrictions on National IV vehicles. Below are the relevant details: 1. Scrap policy: There are clear regulations that do not set a mandatory scrap period for private passenger vehicles, only a guideline for scrapping after reaching 600,000 kilometers. Light and heavy-duty trucks have a mandatory scrap period of 10 years, but this can be extended up to 5 years, meaning the maximum mandatory scrap period for National IV trucks is 15 years. 2. Implementation time of National IV emission standard: The National IV emission standard was implemented starting from July 1, 2010, until July 1, 2017, when the National V standard was fully implemented nationwide. Therefore, vehicles produced between 2011 and 2017 are mostly compliant with the National IV emission standard.
