What is the following distance when driving below 100 km/h on the highway?

When driving on the highway at speeds below 100 km/h, the distance between your vehicle and the one in front in the same lane can be appropriately reduced, but the minimum distance must not be less than 50 meters. Below is relevant information about following distances: Road speed limit requirements: According to traffic experts, speed limits are primarily set based on the road environment and traffic flow needs. For example, some suburban roads may only have two lanes in each direction but allow speeds up to 70 km/h; in urban areas, some roads may have eight wide lanes but are densely populated with inconvenient traffic, likely resulting in speed limits of 40 km/h or 60 km/h. Different speed limits for different road sections: Even on the same highway, speed limits can vary for different sections, especially on sharp curves, slopes, tunnels, bridges, ramps, and construction zones. These limits may be adjusted and can change based on actual conditions. Generally, the maximum speed limit for passenger cars on highways is 120 km/h, but due to factors like road environment in the actual design and construction of highways, speed limits can range from 80 km/h to 120 km/h.

Should You Use the Clutch or Brake to Control Speed in First Gear?

When controlling speed in first gear, you should use the brake. Below is a related introduction about gear positions: Concept: Gear positions are adjustment devices that regulate the speed and traction (torque) of a car. The lower the gear, the slower the speed, but the greater the car's traction (torque). The higher the gear, the faster the speed, and the smaller the car's traction (torque). Gear positions are generally divided into two main categories: forward gears and reverse gear. Engaging a forward gear makes the car move forward, while engaging the reverse gear makes the car move backward. Common car gear positions: Typically, a standard car has five forward gears and one reverse gear. The first forward gear is the starting gear, where the speed is the slowest (0-10 km/h), but the torque is the highest. Applications of each gear: First gear is also suitable for climbing steep slopes. After starting, when the engine speed reaches around 2000 rpm, shift to second gear, which is suitable for low-speed urban driving and climbing gentle slopes. Similarly, shift to the next gear when the speed reaches around 2000 rpm. The fourth and fifth forward gears are high-speed gears, suitable for driving on highways with good road conditions.

What do service brake and engine brake mean?

Service brake and parking brake mean the following: The parking brake refers to the handbrake. Emergency braking is mainly distinguished from anticipatory braking, which means immediately taking braking measures when an emergency is detected to stop the vehicle in the shortest possible time. Engine braking refers to using the engine's drag force to implement braking. For example, during long downhill descents, prolonged use of the foot brake can cause the brake pads to overheat and fail. In such cases, you can shift to a lower gear and coast at idle speed, using the engine's drag force to control the vehicle's speed. The meaning of the brake is as follows: The brake is the device used to stop the vehicle. Brakes are divided into service brakes (foot brake) and parking brakes (handbrake). During driving, the service brake (foot brake) is generally used to slow down or stop the vehicle while moving forward. The brake is not only used to keep the car stationary. The parking brake is used only when the service brake fails. Once the vehicle comes to a complete stop, the parking brake (handbrake) should be engaged to prevent the vehicle from rolling forward or backward. After parking, in addition to using the parking brake, it is advisable to shift into first gear when on an uphill slope to prevent rolling backward, and into reverse gear when on a downhill slope to prevent rolling forward.

What are the emergency measures when a tire suddenly bursts while driving?

Emergency measures when a tire suddenly bursts while driving are as follows: In the event of a front tire blowout, firmly grip the steering wheel to keep the vehicle moving as straight as possible, while avoiding sudden braking. Since most vehicles are front-wheel drive, jerking the steering wheel or braking suddenly may cause the vehicle to roll over. While maintaining control of the vehicle, apply the brakes gently to gradually reduce speed, then pull over to the side of the road at a safe speed. After stopping, set up a warning triangle as soon as possible to alert approaching vehicles and prevent secondary accidents. Rear tire blowouts are relatively less dangerous, but the handling method is similar. Before driving, it is advisable to check the vehicle's condition, including tire pressure, fuel level, and oil status, to prevent accidents. Analysis is as follows: Do not brake to reduce speed under any circumstances, as the vehicle's center of gravity will shift toward the side of the blown-out tire, and braking will exacerbate this shift, potentially causing a rollover. When a tire blows out, it is crucial to maintain control of the steering wheel and make appropriate corrections. Generally, when a high-speed blowout occurs, the vehicle will rapidly veer toward the side of the blown-out tire. If you cannot remain calm and apply the correct steering correction, the vehicle will be unable to maintain its direction, swaying dangerously back and forth on the road.

What are the main materials of brake pads?

Main materials of brake pads: 1. Resin-based brake materials; 2. Powder metallurgy brake materials; 3. Carbon composite brake materials; 4. Ceramic-based brake materials. Automobile brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. The steel plates are painted to prevent rust, and the temperature distribution during the painting process is detected by SMT-4 furnace temperature tracker to ensure quality. Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration.

What Causes the Speaker on One Side of the Car Door Panel to Stop Working?

Speaker malfunction may be caused by poor sealing leading to moisture, poor contact at the electromagnetic coil terminals, or contact point erosion. Poor Sealing Leading to Moisture: Although the speaker interior is sealed, if the sealing is not tight, moisture can enter during car washing or water vapor in the internal space can cause the contacts to become damp, preventing normal operation. Poor Contact at the Electromagnetic Coil Terminals: Some speakers have aluminum metal rivet crimp connections for the enameled wire terminals of the internal electromagnetic coil, rather than secure welded connections. If the insulation varnish on the wire ends is not properly removed or the rivet crimping is not secure, it can easily lead to intermittent contact faults, resulting in poor speaker performance. This type of fault is due to speaker quality issues and cannot be repaired; only replacement with a new part is possible. Contact Point Erosion: Prolonged use of the horn can cause the speaker contacts to erode, creating resistance. This reduces the current flowing through the electromagnetic coil, weakening the electromagnetic force and preventing it from attracting the armature to drive the diaphragm for normal vibration. This results in a hoarse sound or even complete silence. However, when the horn is pressed continuously, a momentary strong current passing through the resistance can still allow normal operation, leading to intermittent functionality.
