What is active safety and passive safety of automobile?

  Ordinary consumers are often confused by the words "active" and "passive". In this issue of Elecdeer's blog sharing, we will introduce various configurations and designs of active safety and passive safety of automobiles.

  Safety is always a hot topic in today's automobile industry. With the increasing importance of automobiles to human life, automobiles have become a part of every modern life. Since the invention of the first car, the word car accident has become a part of human life. As the vehicle's performance is getting better and faster, the risk cost caused by a traffic accident is getting higher and higher. In order to ensure the safety of automobile consumers and get the best guarantee, safety design has become the most important part of modern automobile design, and the cost of safety configuration is increasing in the proportion of automobile production. With decades of development, safety considerations have been added to the design of chassis, the building of car body, and the design and safety of every key component.


  Generally speaking, the distinction between active safety and passive safety configuration is mainly based on the impact when accidents occur. Active safety configuration mainly refers to the auxiliary devices that are operated before impact. These devices will start when the vehicle is close to out of control, and intervene in driving actions in various ways, hoping to use mechanical and electronic devices to maintain the control state of the vehicle, and make every effort to enable the driver to regain control of the vehicle and avoid accidents.

  The so-called passive safety device passively protects the passengers in the situation that the accident is inevitable and the vehicle is out of control. It is hoped that the occupants in the vehicle can be fixed in a safe position through the fixing device, and the structural guidance and collapse can be used to absorb the impact force as much as possible to ensure the safety of the occupants in the vehicle to the maximum extent. Common driving AIDS such as ABS and VSC belong to active safety configuration; The safety belt, airbag, and cage car body structure are passive safety configuration and design.

  Safe driving is the most important. Here, we must remind all netizens that active safety configuration and passive safety configuration are "auxiliary" devices when the vehicle runs, and they are auxiliary devices when the vehicle exceeds the control limit. Assembling these auxiliary devices can not ensure the absolute safety of driving, but can only reduce the probability of accidents and injuries. The key to safe driving is still proper maintenance to ensure the normal operation of vehicle institutions and safe driving behavior.

  ABS is the most well-known auxiliary system among automobile active safety auxiliary systems, and it is also the most accessible active safety auxiliary system for general consumers. ABS is the abbreviation of Antilock Brake System, and its full name in Chinese translation is an anti-lock brake system. As the name implies, with the assistance of ABS, it can prevent the vehicle from locking when braking, thus improving the handling performance of the vehicle and increasing driving safety.


  As we all know, when a vehicle runs on the ground, it depends on the friction between the wheels and the ground, which is generally called grip in the field of automobiles. There is a limit to the grip between the wheel and the ground. Therefore, if the combined force of acceleration, steering, braking and other forces acting on the wheel exceeds the grip between the wheel and the ground, the wheel and the ground will change from the original rolling mode to the sliding mode, and it will become impossible to control according to the steering wheel, resulting in runaway slip.

  To sum up, this article has shared the active safety and passive safety of automobiles. I believe everyone will know more and more about car safety. I hope this article will be of great reference value to readers. If you want to know more interesting knowledge, you can browse other articles in our blog or keep an eye on our updates.
