Safety system of automobile
When driving a vehicle, it is inevitable to encounter accidents or obstacles ahead. When the driver treads the brake pedal with all his strength, the braking force can be greatly improved and the vehicle can be effectively decelerated. However, if the braking force is too large, it may exceed the grip between the wheel and the ground, resulting in the situation of slipping out of control. Under the condition of losing control, the vehicle will advance in the inertial direction, unable to turn according to the operation of the steering wheel, and unable to dodge. Unless the friction and resistance of the vehicle sliding are enough to stop the vehicle before the obstacle, the vehicle will hit the obstacle due to inertia.
The function of the ABS system is to make the driver keep the ability of control while braking urgently and to keep the ability to dodge while slowing down. ABS was invented to avoid the above-mentioned runaway slip phenomenon of emergency braking. Vehicles equipped with ABS systems will use the sensors of wheels to monitor whether the wheels are locked. When the wheels are locked, the ABS system will intervene under the brake system to release the brake pressure, release the brakes of the locked wheels, let the wheels roll again, let the vehicle regain the ability to control, and then restore the brake pressure, so that the vehicle can continue to slow down. So repeatedly, with the concept of time-sharing, the braking system of the vehicle can continuously brake-release-brake-release, so that the vehicle can keep the ability of control between the breaks of braking so that the vehicle can avoid obstacles and avoid accidents.
Use ABS correctly:
The advanced ABS system can perform the above actions several times to ten times in one second, so as to minimize the sliding of the vehicle and maintain the vehicle's control and dodge ability while maintaining a good braking effect. In case of emergency braking, the driver only needs to step on the pedal at the fastest speed, and ABS will intervene in the braking operation in due course. When the ABS system is actuated, the brake pedal will bounce back due to the repeated release of pressure in the brake system. This is a normal phenomenon, so the driver should not panic, and continue to press the pedal hard to keep the ABS system actuated, so as to maintain the braking and steering power. Never let go of the pedal because of this! If you release the pedal, you will lose the braking effect of the vehicle and increase the danger.
Because in the real world, the condition of the pavement is not as perfect and uniform as the theoretical condition, depending on the pavement materials and service conditions, the friction coefficient of pavement is often different; However, the difference of friction coefficient of pavement is even greater in sections with sand accumulation, water accumulation and icing. In this case, if the road conditions of the left wheel and the right wheel of the vehicle are different, the obtained grip will be different. In the case of acceleration, the wheels with lower grip may slip and reduce the driving force, while the road with better grip and the greater driving force will make the vehicle deviate from the original route in the direction with a lower grip.

The traditional brake system is designed to amplify the force applied to the brake pedal by a fixed multiple. Therefore, users with weak physical strength may face the problem of insufficient braking force, and in case of emergency, accidents may occur. To solve this problem, engineers developed BAS(Brake Assist System) braking force auxiliary system, which makes up for the lack of physical strength by engineering technology, so that drivers can generate enough braking force and prevent accidents. The BAS system will monitor the action of the brake pedal all the time during the running of the vehicle. When the sensor detects that the brake pedal is stepping down at an extremely fast speed, the system interprets it as the driver's emergency braking action, and the BAS system will pressurize the brake system to generate the maximum braking force so that the vehicle can have the best braking effect and improve the driving safety.
With the increasing importance of automobile products to human life, driving a car has become a common behavior. Both men, women and children are the main users of automobile products. Correct use of automobile safety systems to improve driving safety.
