How Many Chances Are There for the Subject 3 Safe and Civilized Driving Test?

What is the principle of EABS electronic braking?

ABS system, also known as the Anti-lock Braking System, operates on the following principle: During braking, the ABS system monitors the speed signals from each wheel speed sensor. It closes the normally open input solenoid valve for the wheel that begins to lock up, maintaining a constant braking force. If the wheel continues to lock, the system opens the normally closed output solenoid valve. This ensures the braking state remains at the optimal point, achieving the best braking performance and maximum driving safety. ABS, short for Anti-lock Braking System, functions by automatically controlling the braking force during vehicle deceleration to prevent wheel lock-up. It maintains the wheels in a rolling-sliding state (with a slip ratio of around 20%), ensuring maximum traction between the tires and the road surface. The ABS system primarily consists of four components: wheel speed sensors, the electronic control unit (ECU), the hydraulic unit, and the ABS warning light. The wheel speed sensors detect the motion state of the wheels and generate sinusoidal electronic pulse signals. These signals are processed by a modulator, converted into digital signals, and transmitted to the electronic control unit. The central electronic control unit (ECU) receives input signals from the wheel speed sensors. Based on these signals, it calculates the wheel speed, vehicle speed, and slip ratio. It then determines the wheel condition and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands. The adjustment process includes pressure maintenance, pressure increase, and pressure decrease. The ABS warning light alerts the driver to any system malfunctions. If the ABS warning light illuminates, it is advisable not to continue driving. An illuminated ABS light indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to decelerate or adjust the vehicle's trajectory, posing significant safety risks.

What happens if a vehicle violation is not handled for more than 30 days?

Late fees will be charged, and the traffic management department may apply to the court for compulsory enforcement. Here are the specific details: 1. Violation Handling: If violations are not addressed, and two more violations occur without being handled, the traffic police department has the authority to detain the driver's license and the vehicle until all violations are resolved by the owner. Failing to handle violations on time may affect services related to the driver's license and vehicle registration, and the vehicle's annual inspection cannot be conducted. It is recommended that vehicle owners regularly check for violation records on the traffic management department's online platform and handle any violations promptly. 2. Traffic Regulations: If the traffic management department of the public security authority imposes penalties such as temporary suspension or revocation of a driver's license for a non-local driver, the driver's license must be transferred to the issuing authority's traffic management department within 15 days from the date of the penalty decision.

What is the fuel consumption per 100 kilometers for a 5.0-liter engine?

Fuel consumption cannot be simply determined by engine displacement; road conditions are the most important factor, followed by driving habits, load conditions, vehicle weight, engine and transmission specifications, and other aspects. Below is an introduction related to automobile engine displacement: 1. Displacement and automobiles: The volume of space that a piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If an engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, which represents the size of the engine more accurately than cylinder bore and number of cylinders. Many indicators of the engine are closely related to displacement. 2. Displacement classification: In China, the classification of passenger cars is determined by the size of the displacement. The displacement of a mini car is less than or equal to 1.0L; the displacement of a compact car is in the range of 1.0–1.6L; the displacement of a mid-size car is in the range of 1.6–2.5L; the displacement of an executive car is in the range of 2.5–4.0L; and the displacement of a luxury car is greater than 4.0L.

How much can a roadside fast charger charge in 10 minutes?

Charging for 10 minutes can bring the battery to 80% of its capacity, which is about 60%~70% of the range of a fully charged battery. Basically, 10 minutes of charging can achieve an effect of about 3 kilometers. Below is some related information about charging piles: 1. Current: Generally, fast chargers have a charging current of 10A, so charging for 10 minutes would be 1.666AH. Based on a vehicle driving current of 10A, it can drive for 10 minutes. At a speed of 30KM/H, it can drive about 5KM. 2. Battery: After an electric vehicle battery is discharged, passing direct current through the battery in the opposite direction of the discharge current restores its working capacity. This process is called battery charging. When charging, the positive terminal of the battery is connected to the positive terminal of the power source, and the negative terminal of the battery is connected to the negative terminal of the power source. The voltage of the charging power source must be higher than the total electromotive force of the battery. 3. Charging methods: There are two types—constant current charging and constant voltage charging.

Will the Engine Stall if the Clutch is Fully Released in Subject 2?

Because the clutch is released too quickly, causing the engine to stall. Here is a relevant introduction about Subject 2: 1. Overview: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skill test. For small cars (C1 and C2), the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns). Some regions also include a sixth item: high-speed card collection. 2. Teaching aids: Teaching software: Students can learn traffic regulations through driver simulation test software on mobile or computer devices. Teaching books: "Safe Driving Starts Here," compiled by the Ministry of Transport of the People's Republic of China. Driving schools may provide learning materials uniformly, or students may purchase them at their own expense.

Can I stay in first gear with the clutch pressed while waiting at a red light?

You can stay in first gear with the clutch pressed while waiting at a red light. Here is more relevant information: 1. Intersection stopping technique: If the speed is a bit high, first press the brake to reduce speed. Then press the clutch, allowing the vehicle to coast smoothly to the stop line, preferably leaving 1-2 meters in front. After stopping, gently shift into first gear and press the clutch and brake (for exams, instructors recommend staying in first gear during the test, but in actual driving, you can shift to neutral if the red light is long). 2. Starting technique: When the red light countdown reaches 6-8 seconds, slowly release the clutch to the engagement point, making the front of the car slightly tremble. When the light turns green in 2 seconds, release the foot brake to complete the start. Using the semi-engagement method prevents stalling. Release the clutch, press the accelerator to increase speed, shift to second gear when reaching the middle of the intersection, and then shift to third gear after exiting the intersection.
