The car B-pillar refers to the vertical pillar between the driver's side window glass and the rear side window glass. Its blind spot is mainly on the right side of the vehicle, which may lead to collisions with vehicles driving normally on the right side. Cars are divided into A-pillars, B-pillars, and C-pillars. The A-pillar is the vertical pillar between the front windshield glass and the driver's side window glass, while the C-pillar is the vertical pillar between the rear side window glass and the rear windshield. The B-pillar is mainly used to support the roof, front and rear doors, and to assemble components such as seat belts and wiring. When the vehicle is impacted from the side, the B-pillar plays a protective role for the occupants inside the car. Thanks to high-tech materials such as carbon fiber and high-strength alloys, the B-pillar is widely used in the car body.

What to Do About Abnormal Noises from the Car Steering Wheel?

Abnormal noises from the car steering wheel can be analyzed from two aspects: the steering wheel dust cover and the interior of the steering wheel. Here are the detailed explanations: 1. Abnormal noises from the steering wheel dust cover: If the noise comes from below the steering wheel, it is likely caused by the steering wheel dust cover. Solution: The owner only needs to apply some grease inside the dust cover, and the noise will disappear. 2. Abnormal noises from inside the steering wheel: If the noise comes from inside the steering wheel, it may be necessary to replace the clock spring (spiral cable) because it is damaged. Solution: Remove the airbag fuse.

What Causes Chassis Noise While Driving?

Causes of chassis noise while driving: 1. If there is noise when turning the steering wheel and it is not the sound of tire friction with the ground, it is likely caused by a damaged outer CV joint. Replacing the outer CV joint can eliminate the noise; 2. Noise from the rear wheel area is usually emitted from the connection between the rear axle and the shock absorber. Check if the screws at the connection between the rear axle and the shock absorber are loose and tighten them if necessary; 3. If the chassis makes a creaking sound while driving, it is likely coming from the connection between the MacPherson strut and the shock absorber. You can park the car in a relatively quiet place, turn off the engine, press down on the four shock absorbers with both hands, and move the body up and down to make the car sway. During this process, you can hear which part is making the noise.

What does the mode function in a car mean?

mode on the multifunction steering wheel refers to switching between controlling the car's multimedia and CD modes. Below is an introduction to the mode function on the multifunction steering wheel: 1. Music function: The in-car music playback function is probably one of the most common in-car media functions, and also one of the most original in-car media. 2. GPS navigation function: The GPS navigation function is another commonly used multimedia feature besides the in-car music function. 3. Rearview camera: The in-car rearview camera is a must-have for both new and experienced drivers when parking. It not only completely displays the blind spots at the rear of the car on the central control LCD screen, but many also come with night vision capabilities.

What is the basic principle of PWM?

PWM works by controlling the switching of inverter circuit devices to produce a series of equal-amplitude pulses at the output, which are used to replace sine waves or other desired waveforms. PWM stands for Pulse Width Modulation, and the following introduces the method of pulse width modulation: 1. The role of overall pulse width modulation: Overall pulse width modulation involves designing a controller for the control object and performing dynamic mathematical calculations on the entire system model based on the required control force, determining the duration and start time for a fixed force output. 2. Operation of the pulse width modulator: The pulse width modulator does not consider the control object model but performs 'dynamic attenuation' accumulation based on the input. After some algorithmic transformation, it determines the duration of the output. This method is very simple and can achieve approximately the same output effect.
