Why is the car unstable at high speed?

What car is represented by an exclamation mark?

The exclamation mark logo belongs to the Ora brand, which is part of Great Wall Motors' Haval division. It is the first standalone new energy vehicle brand among China's popular independent automakers. To commemorate the renowned global scientist "Mr. Euler," the brand was named "Ora," symbolizing Great Wall Motors' commitment to meticulous craftsmanship and persistent efforts in creating high-end vehicles. Established in 2018, Ora positions itself as the world's most beloved car brand for women, aiming to establish correct values in the industry regarding female customers. Understanding the logo's meaning helps grasp the company's development vision and goals. Ora's logo is derived from an exclamation mark, symbolizing tribute and greetings—paying homage to Mr. Euler, greeting customers, and saluting the world. However, there is another interpretation: the logo is said to consist of the number 0 and an exclamation mark. What does this mean? The 0 represents zero emissions, 100% environmentally friendly with no pollution, while the exclamation mark ! signifies surprise, implying that the brand can continuously create surprises for people, bringing more hope and anticipation. The Ora brand is market- and customer-oriented, refusing to engage in "oil-to-electric conversions" or produce "policy arbitrage vehicles." After over a decade of research and development, it established itself as a pure electric vehicle brand. The models feature an open design, offering customers a refreshing feel and providing excellent safety and reliability guarantees. Ora currently offers four models: the first is the Ora White Cat, a micro-level car; the second is the Ora Black Cat, also a micro-level car; the third is the Ora Good Cat, a small-level car; and the fourth is the Ora IQ, a compact-level vehicle. Ora cars are moderately priced, and as new energy vehicles, they qualify for national subsidies, making them an excellent choice as a family's second commuter car. Since its launch, Ora's sales have skyrocketed. With the promotion of new energy vehicles, it offers consumers a green travel experience, not only supporting national environmental initiatives but also helping to save on energy costs.

How many points are deducted for the car body crossing the line in Subject 2?

In Subject 2, if the car body touches the line, it results in immediate disqualification with a deduction of 100 points. Below is a detailed explanation of the reasons for crossing the line and methods to avoid it. Reasons for the car body crossing the line: If you turn the steering wheel fully to the left too early, the left rear wheel of the vehicle will still be far from the edge of the parking space, making it impossible to park the car properly after straightening the body. If you turn the steering wheel fully to the left too late, the left rear wheel of the vehicle will already have crossed the edge of the parking space, causing the right side of the car to go out of the parking space line when the body is straightened. Methods to avoid the car body crossing the line: You need to maintain a steady pressure on the accelerator pedal to keep a consistent driving speed, and be sure to find the correct reference points when turning. Use the rearview mirror to observe the distance between the car body and the edge line in a timely manner, and follow the principle of "steering toward the wider side" when adjusting the direction.

What is Tested in Subject 4?

Subject 4 primarily covers the following content: safety and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-traffic accident handling knowledge. The Subject 4 test paper consists of 50 questions proportionally selected from the corresponding Subject 4 question bank based on the type of driver's license being tested. For small vehicle licenses, questions are drawn from a pool of 800, while large vehicle licenses draw from 1023 questions. Each question is worth 2 points, with a perfect score of 100 and a passing score of 90. If 6 mistakes are made during the test, the exam will automatically terminate. Questions are primarily presented in the form of case studies, images, animations, etc., with question types including true/false, single-choice, and multiple-choice. On the day of the Subject 4 test, there are two attempts. If the first attempt is unsuccessful, an immediate retake is allowed. Passing the test grants the driver's license. Both attempts count as one appointment. Failing both results in a failure, requiring a new appointment. There are no restrictions on scheduling the Subject 4 test, but the driving skill test permit is valid for three years. If the applicant fails to complete the test within this period, previously passed subject scores will be invalidated. Below are the precautions for the Subject 4 test: Verify Information: Upon sitting down, first verify the examinee information. If it does not match your details, check if it is your assigned seat. If not, locate your correct seat. If the seat is correct but the information is wrong, report it immediately. Adhere to Test Center Rules: During the Subject 4 test, follow the test center rules. Loud noise during the waiting period may result in immediate expulsion and cancellation of the day's test eligibility. Follow Instructions: Obey staff arrangements. Raise your hand for assistance and ask the proctor if you have any questions—do not be afraid. Adjust Camera Position: Adjust the camera to focus on the upper third of your face and chest. If your face is not within the monitoring range, your score will be invalidated.

Where to Handle Traffic Violation Points Deduction for Cars?

If it is a roadside check, you need to go to the designated traffic police station for processing. If it is captured by an electronic eye, you can go to the nearest vehicle management office or violation processing booth. Consequences of not paying on-the-spot fines: If an on-the-spot fine is not paid within 15 days, late fees will be incurred. If more than 3 violations are left unprocessed and detected by traffic police, your license may be suspended, and in severe cases, your vehicle may be impounded. If on-the-spot fines are not processed, the driver's license cannot be renewed, replaced, or transferred. In case of accidents or vehicle damage, the vehicle insurance company will not provide compensation. The vehicle will also fail the annual inspection. Documents required for handling violations: To handle violations, you need to bring the vehicle registration certificate, your driver's license, ID card, and the penalty slip. Go to the local traffic police station or branch to print the violation penalty decision form, and pay the fine at the designated bank within 15 days.

What does a parking system malfunction in a car mean?

The parking system refers to an automatic braking function, and a parking system malfunction is caused by sensor issues that prevent the automatic braking function from being realized. After activating this function, such as when stopping at a red light, it is equivalent to not needing to pull the handbrake, simplifying the operation by avoiding the use of a handbrake or electronic handbrake. For automatic transmission models, it also eliminates the need for frequent switching between D to N and D to P. The automatic parking system (AUTO HOLD) is a technological application that enables automatic handbrake functionality while the car is running. This technology allows drivers to avoid prolonged braking when the vehicle is stationary and prevents unnecessary sliding when the automatic electronic parking brake is engaged. The implementation of the automatic parking system function is not simply achieved by using an electronic handbrake. When people park on slopes or before traffic lights, they use the handbrake for parking. In such cases, relying solely on the electronic handbrake results in slower response times. Manually pulling or releasing the handbrake takes no more than 0.3 seconds, and manual control is more flexible than electronic control. Activating the electronic handbrake requires a preliminary action of pressing the brake pedal, along with the response time of the button, and the motor operation time is relatively long, about 0.5 seconds. Even when the electronic handbrake is automatically released upon pressing the accelerator, this action can feel somewhat abrupt. Therefore, the automatic parking system operates on a different principle. The causes of electronic parking system malfunctions are: The parking brake lever cannot be fixed; The parking brake fails; The parking brake makes abnormal noises or is aged; Excessive gap between the friction pads and the brake drum; Oil contamination or severe wear on the friction pads and brake drum. The solutions for electronic parking system malfunctions are: Replace the parking brake; Adjust the gap between the friction pads and the brake drum; Clean the friction pads and brake drum; After starting the vehicle, press the foot brake and hold the electronic handbrake to reset.

What is the typical turning radius for a small car in meters?

The typical turning radius for a small car is 6 meters. Calculation method for turning radius: Based on the track of the outer center of the steering wheel, the minimum turning radius is calculated from the outermost point of the vehicle body; where R0—the minimum turning radius of the outer center track of the steering wheel; R—the minimum turning radius of the outermost point of the vehicle body, L—wheelbase, θmax—the maximum steering angle of the outer steering wheel, front track, front overhang length, overall vehicle width, kingpin center distance. The turning radius of the vehicle is defined as R, the distance from the vehicle's longitudinal symmetrical plane to the instantaneous turning center O. Here is an introduction to the turning radii of various types of vehicles: 1. Microcars have a turning radius of 4.50m. 2. Small cars have a turning radius of 6.00m. 3. Light vehicles have a turning radius of 6.50-8.00m. 4. Medium-sized vehicles generally have a turning radius of 8.00-12.00m. 5. Articulated vehicles generally have a turning radius of 10.50-12.50m. 6. Ordinary fire trucks have a turning radius of 9.00m. 7. Large fire trucks generally have a turning radius of 12.00m. 8. Aerial fire trucks have a turning radius of 12.00m. 9. Some special fire vehicles have a turning radius of 16.00-20.00m. Here are four points to note when turning a car: Use turn signals: You must turn on the turn signal when turning, otherwise the driver behind may misjudge, leading to unnecessary casualties. Avoid turning the steering wheel too sharply: When turning, reduce speed and avoid turning the steering wheel too sharply to prevent excessive centrifugal force causing the car to skid. Avoid coasting into turns: In neutral gear, the engine cannot control the rotation of the wheels, and the car moves by inertia. All braking and steering operations are significantly less effective, which can easily lead to safety hazards. Turn left in a wide arc: To avoid obstacles or collisions, try to turn as far as possible.
