How to Install an ETC Device?

ETC device installation process is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly illuminate. The OLED screen will display "Label Invalid" and "Please Insert Card," indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device. ETC installation positions: For small vehicles like cars and minivans, the ETC card and OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the electronic tag surface and the horizontal plane).

Is it legal to install a rear wing on a car?

It is legal to add a rear wing to a car. When modifying the rear wing, the car owner must file a record with the vehicle management office in advance and take new photos to update the images on the vehicle license after the modification is completed. A car rear wing refers to the ducktail-like protrusion installed at the rear end of the car's trunk lid. It is part of the car's aerodynamic kit and mainly serves to reduce the lift at the rear of the vehicle. The following vehicle modifications are not considered illegal: 1. Rear wing modification: When modifying the rear wing, the car owner must file a record with the vehicle management office in advance and take new photos to update the images on the vehicle license after the modification is completed. 2. Body color: The body color can be changed, but the owner must go to the vehicle management office within 10 days to take new photos and apply for a change of registration. Some law enforcement vehicle color schemes are not allowed to be altered. 3. Partial painting: If the body color change is within 30% of the total area, there is no need to go to the vehicle management office to update the vehicle license. Additionally, wheels can be modified, but the size must remain the same as the original vehicle. The color or appearance can be changed freely, and no special registration for the change is required.

How Does Automatic Braking Work?

Automatic braking works primarily by relying on sensors installed at the front of the vehicle to monitor road conditions in real-time. When an obstacle is detected ahead with a specified risk coefficient, the system will issue audible and visual alerts to warn the driver or automatically trigger emergency braking. Advanced driver assistance systems like automatic braking have their rationale for existence. From a physiological standpoint, relying solely on human judgment and reaction cannot completely prevent collision accidents. Automatic braking refers to the vehicle's ability to actively generate braking force to slow down when encountering sudden hazardous situations during normal driving, even without adaptive cruise control engaged.

Brief Introduction to the Structure and Working Principle of a Clutch

Clutch working principle: It is located between the engine and the transmission, used to transfer the torque stored on the engine flywheel to the transmission, ensuring that the vehicle delivers appropriate driving force and torque to the drive wheels under different driving conditions. Clutch components: The clutch consists of friction plates, spring plates, pressure plates, and a power output shaft. Below are the relevant details: 1. Clutch working states: The clutch operates in three states: disengaged when the clutch pedal is pressed, fully engaged when the clutch pedal is not pressed, and partially engaged when the clutch pedal is partially pressed. 2. Clutch operation: When the vehicle starts, the driver presses the clutch pedal, which moves the pressure plate backward, separating it from the friction plate. At this point, the pressure plate and flywheel are not in contact, so there is no relative friction. During normal driving, the pressure plate is tightly pressed against the friction plate on the flywheel, creating maximum friction between them. The input and output shafts maintain relative static friction, rotating at the same speed. The third state is the partially engaged clutch, where the friction between the pressure plate and the friction plate is less than in the fully engaged state. Here, the pressure plate and the friction plate on the flywheel are in a state of sliding friction, with the flywheel rotating faster than the output shaft. This allows part of the power from the flywheel to be transferred to the transmission. In this state, the connection between the engine and the drive wheels is akin to a soft linkage.
