What are the blind spots of cars and how to deal with them?

A-pillar blind area. Generally, a car has three columns on each side, of which the oblique columns on both sides of the front windshield are called the A pillar. Whenever the car turns or enters the curve, the driver's vision will be partially blocked by the A-pillar, creating a blind spot in the field of vision. Blind spot of inner wheel difference.

The most common man-made blind spot is that many car owners like to put a lot of plush toys under the rear windshield, which blocks the view of the rearview mirror in the car, leading to danger. Therefore, don't do this for the so-called decoration of your car.In addition to the rear windshield, try not to put anything to block the view on the co-driver's seat, otherwise it will be very dangerous.

Reflective blind area If the isolation pier on the highway is reflective, it will cause a large visual blind spot for the driver. Some drivers can't judge the speed and distance because of the reflection, resulting in rear-end accidents. In order to avoid this situation, the driver can install a protective plate or maintain the distance to avoid accidents due to reflection.

A-pillar blind area A-pillar refers to the front windshield. The oblique columns on both sides of the car are called the A column. Whether turning or driving in a straight line, part of the driver's sight will be blocked by the A-pillar. Cause visual blind spots.

There are several factors that cause the blind area of the front blind area caused by the car itself, such as the height of the car body, the height of the seat, the length of the front of the car, the figure of the driver, etc. are all related. If the distance of the front blind spot is not well controlled, tailgating is easy to occur.

New Energy Vehicle Industry Regional Differentiation

1. At present, China's new energy vehicle industry is mainly concentrated in Zhusan Angle, lengthTriangle, Beijing-Tianjin-Hebei and other regions, among which, representative enterprises in the Pearl River Delta include BYD, Xiaopeng Automobile, GAC Aian, etc.; Tesla, Geely Group, etc.; representative enterprises in Beijing-Tianjin-Hebei include Great Wall Automobile, Xiaomi Automobile, Ideal Automobile, etc.

2. In this way, whether new energy vehicle enterprises have innovation, core technology, and complete industrial chain determines the final result of the market share competition. Obviously, under the condition that the market accelerates the victory and defeat, the phenomenon of internal differentiation is an inevitable purge.

3. Promote the development of regional key industrial clusters. The development and research of new energy vehicles itself cannot be completed by an enterprise alone, so the Ministry of Industry and Information Technology began to guide many new industrialized enterprises to communicate, research, cooperate and produce with these new energy enterprises.

So how to identify the inside and outside blind spots of cars?

1. The front blind spot The place where it cannot be directly observed in front of the hood is called the front blind spot. There are many factors for the formation of the front blind area, which is usually related to the length of the front of the car, the length of the driver's upper body, the height of the driver's seat, etc. If the front blind area is not well controlled, it is easy to lead to tailgating events.

2. Rearview mirror blind area: The rearview mirrors on both sides of the car can only see both sides of the car body, and cannot fully collect all the information around the car body, especially from the main road of the auxiliary road. The vehicle cannot be observed from the left rearview mirror. If you accelerate to cut the innermost lane at a large angle, it is easy to drive at high speed with the innermost lane. The car collided.

3. When driving, the driver should often "look left and right".The rear blind area of the trunk belongs to the rear blind area. Although most vehicles are equipped with reversing radars or reversing images, the radar also has corners that cannot sweep (such as the bottom of the car) and is sometimes misjudged, so you should not rely too much on electronic assistive devices.

4. Find visual blind spots: All three-dimensional obstacles will produce visual blind spots, and there will be a possibility of moving objects. In driving observation, it cannot be limited to the direct view and position, and the front and rear conditions must also be deeply observed.

5. Blind area A-pillar blind area During driving, if you turn or parallel, the driver will not be able to see the road ahead due to the blocking of the A-pillar. Although the A-pillar of the vehicle becomes narrower after the speed increases, it will still block the view. Drivers should be extra careful when turning or paralleling to prevent mistakes in judging passing vehicles.

How much do you know about the key technologies and MCU solutions of automotive regional controllers?

1. Wireless communication technology Long-distance wireless communication technology is used to provide instant Internet access, mainly using 4G/5G technology, especially 5G technology, which is expected to become a special technology for long-distance wireless communication in vehicles.

2. MCU refers to the power electronic unit unique to new energy vehicles that controls the motor to output the specified torque and speed to drive the vehicle by receiving the vehicle driving control instructions of VCU. It realizes the conversion of the DC energy of the power battery into the required high-voltage alternating current, and drives the motor body to output mechanical energy.

3. Electric vehicle motor control is a key element to achieve the performance, efficiency and reliability of electric vehicles.Single-chip microcomputer (MCU) plays a key role in electric vehicle motor control. It supports the efficient operation of motors by providing functions such as high-performance computing, sensor interface, communication interface, functional security and power management.

4. Just like the left and right brains of people, SOC is responsible for data processing, MCU is responsible for logical calculation, realizing the integration of four domains, and applying regional control technology to reconstruct the distribution of the whole vehicle sensor and actuator, realize standard interface communication, and shorten the length of the whole vehicle harness to 5km.

5. The controller plays a key role in the normal driving of the car, the management of the whole vehicle, gear management, torque control, accessory control, fault diagnosis and processing and other functions. MCU is the unique core power electronic unit of new energy vehicles and the brain of the motor.

6. Environmental perception technology Environmental perception includes vehicle's own state perception, road perception, pedestrian perception, traffic signal perception, traffic sign perception, traffic condition perception, surrounding vehicle perception, etc.

The cleaning of these positions of the car, everyone who knows the car does this

1. It's a little troublesome to clean the roof, and it needs to be cleaned like a carpet with a vacuum cleaner. If there is a stain on the ceiling, you need to clean up the stained area with detergent, and then vacuum the moisture.

2. Car cleaning generally includes car body cleaning, interior cleaning, engine compartment cleaning, wheel hub cleaning, body waxing and polishing, interior care and in-car sterilization and disinfection services. Car washing refers to the cleaning inside and outside the car, which is more meticulous and cleaner than traditional car washing.

3. In daily driving, you can often wipe the steering wheel with wet tissue or use car cleaner to clean it, which has a good effect. Cleaning carpet mats, I don't know if you have heard such a sentence: the cleanliness of the carpet can often tell whether the car owner loves cleanliness! Because the carpet in the car itself is very clean.
