What does collision alarm active brake mean

1. Collision alarm is to use ultrasound, laser, infrared, microwave radio frequency and other ways to detect data to actively avoid collisions and effectively avoid road traffic. Slow down the speed when an accident occurs; active braking is when the car is in a situation, it is not the driver who steps on the brake, but the car brakes by itself, such as: esp configuration.

2. Collision alarm is to use ultrasound, laser, infrared, microwave radio frequency and other methods to detect data to actively avoid collisions, effectively avoid the occurrence of road traffic accidents and slow down the speed; active braking is when the car is in a situation, it is not the driver stepping on the brake, but the car to brake by itself, such as: Esp configuration.

3. The automatic braking system of the car, also known as the automatic anti-collision system of the car, is a part of the intelligent car. It is an intelligent device system that can prevent the collision of the car.

4. The active braking system can realize automatic alarm, automatic deceleration and automatic braking when obstacles are generated in front of the vehicle and pose a threat to the safe driving of the vehicle, so as to minimize the collision risk and achieve active collision prevention.

5. Active braking means a device for the vehicle to take the initiative to brake, that is, when the car is in an emergency, it is not the driver who takes the initiative to step on the brake, but the braking system in which the vehicle will brake autonomously.

6. The active braking function refers to the normal driving of the vehicle under non-adaptive cruising. If the vehicleIn case of emergency, it can actively generate a braking effect and slow down the vehicle (but the vehicle with this function may not be able to completely brake the vehicle) to improve driving safety. However, at present, the naming of this technology by various car manufacturers is not uniform.

Compare the characteristics of artificial mainCharacteristics of kinetic immunity and artificial passive immunity

1. It is characterized by fast effect and immediate effect after input. However, because the immunity is not produced by the autoimmune system and is easy to be removed, the immune effect is maintained for a short time, generally only 2 to 3 weeks. It is mainly used for treatment and emergency prevention.

2. Active immunity: a method of using antigen stimulation to make the body produce antibodies, rather than directly introducing antibodies from the autologous. Active immunity has a high degree of resistance to subsequent infections. It can be produced by the pathogen of the disease itself or through immunization.

3. Passive immunity: the human body obtains antibodies directly and passively, such as injecting tetanus toxin, and the fetus obtains antibodies from the mother.

4. The method of obtaining specific immunity. The specific immunity to a certain infectious disease can be obtained by natural immunity and artificial immunity after the disease.Artificial immunity is divided into artificial active immunity and artificial passive immunity.

What are the aspects of the active safety protection system of automobiles

I: Anti-lock system (ABS) The anti-lock system is the most basic system for active safety of automobiles. It can prevent the tail swing caused by sudden braking causing the front wheel to be dead and unable to turn effectively, and greatly improve the safety and stability of the car. Of course, the anti-lock braking system usually has no effect on the braking distance and will not shorten the braking distance.

There is also an ESP electronic stability system, which mainly helps to improve the controllability and stability of the vehicle and prevent the vehicle from losing control when it reaches the dynamic limit in an emergency.

Active security probably includes electronic stabilityThe configuration of system, warning system, ABS, EBD, etc. to remind or assist the driver in driving the vehicle safely before an accident occurs.

Automotive active safety technology has the following aspects: Forward Collision Warning System (FCW). The front collision warning system will predict possible collisions in front of your car through lasers, radars or images, and remind you to maintain a reasonable speed. It will remind you through images or sounds.

Active safety on the car includes: ABS (anti-lock braking system), ESP (body stability system), EDL (electronic differential lock), EBD (electronic brake distribution system), TCS (traction control system), etc. The active safety system is the first barrier to driving safety, avoiding dangerous situations and accidents.

Can you popularize what are the active safety systems of cars?

Seat belts, airbags and side door anti-collision steel beams are all passive safety systems of vehicles.

Active safety on the car includes: ABS (anti-lock braking system), ESP (body stability system), EDL (electronic differential lock), EBD (electronic brake distribution system), TCS (traction control system), etc. The active safety system is the first barrier to driving safety, avoiding dangerous situations and accidents.

At present, the active safety technology on ordinary cars mainly includes: ebd electronic brake force distribution system, abs anti-lock braking system, tcs traction control system, esp electronic stability system, ldws lane departure warning system, panoramic overview system, bsw blind spot warning system, Concurrent auxiliary system, tpms tire pressure detection system, emergency braking system, etc.

What are the active safety systems and passive safety systems of BMW?

Active safety system: PDC, DSC, RSC tires, AHL, AL, NIGHTVISION, automatic headlights and wipers with rain and rain sensing, headlight cleaning system, anti-glare rearview mirror, etc., active bumper.

At present, automotive active safety technology mainly includes these functions: ASS active braking, ABS anti-lock braking, EBD electronic braking force distribution, ESP body stability, TCS traction control, LDWS lane departure warning, panoramic overview, BSW blind spot warning, parallel lane assistance, TPMS tire pressure detection system and so on.

And for such a "top brand" representing Germany's highest safety quality, the full-speed active cruise control system and lane keeping assistance system have long been the standard equipment of L2-level driving assistance.

The active safety system includes brake energy recovery, brake assistance, lane departure warning, etc., which ensures safety during driving; the passive safety system includes front airbags, head airbags, knee airbags, and body rigid enhancement, etc., to ensure the safety of the occupants in the car.

In terms of active safety configuration, this model, which costs 3.69 million yuan, is equipped with AEB (active braking system) and FCW (collision warning system), which belongs to the normal level of this level.
