Today, automotive safety systems have evolved from passive to active forms. In addition to the traditional passive safety systems such as seat belts and airbags, active vehicle safety systems developed to avoid accidents, such as wheel anti-lock braking systems (ABS), electronic stability control systems (ESP, VDC, VSC, VSA, DSC), etc., are gaining popularity.
At the same time, another more advanced automotive active safety system has begun to be used more. This intelligent system of various sensing devices, such as radar, infrared, image system, tire pressure monitoring system, etc., heralds another upgrade of the car safety system.
Pre-collision system protects "inside and out"
In order to avoid the occurrence of traffic accidents, many manufacturers are committed to developing a more advanced automotive active safety system-pre-crash safety system. The pre-collision system is a collection of active and passive safety systems. It integrates ESP and seat belt protection functions. It can not only monitor the state of the vehicle through sensors, but also automatically take countermeasures to reduce danger and protect the driving in the car immediately before the collision. Passengers and pedestrians.
When the pre-collision safety system detects that the vehicle may have a collision through the radar system, it will warn the driver of the vehicle. Once the collision cannot be avoided, the automatic braking system will be activated immediately. The system can also increase the brake oil pressure assistance according to the driver's braking power, so that the braking action can be completed as soon as possible, and the vehicle speed can be reduced to a minimum. At the same time, the pre-collision system will quickly close the window; drive the motor in the seat belt system to rewind the seat belt, fix the driver and passenger in the best position of the seat, let the airbag maximize the function; adjust the headrest position to prevent Neck injuries in the car.
In terms of pedestrian protection, when components such as radar, infrared or image sensors sense that the vehicle body is about to collide with a pedestrian, the pre-collision system will urgently inform the driver. When a collision is unavoidable, the vehicle activates an automatic braking system and an airbag located at the bumper and front windshield to reduce injuries to pedestrians' heads, chests, and feet.
Adaptive cruise system makes autonomous driving possible
From passive safety to pre-collision systems, it is a last resort to deal with crashes, and it is best to avoid collisions. Nowadays, the installation of an adaptive cruise control system (AdapTIve Cruise Control (ACC)) will make it possible to avoid collisions.
Adaptive cruise control system is also called speed control system, or automatic driving system. Its main function is to automatically lock the speed of the vehicle in front. The driver can control the vehicle to maintain a fixed speed automatically without stepping on the accelerator pedal. When following the car, when the vehicle is too close to the vehicle in front, the system automatically decelerates the vehicle and accelerates the vehicle when the distance is far enough to ensure a certain safety distance between the vehicles.
The main operating principle of the system is: the system first locks the target vehicle in front through the sensor, and calculates the movement information of the vehicle in front, such as vehicle speed, acceleration, yaw rate, etc., and then further calculates based on the calculated distance, relative speed, etc. Make a safe distance between the two cars and make acceleration and deceleration actions according to this standard. When the distance between the two vehicles is too close, when the adaptive cruise control system detects a possible crisis, it will issue a warning signal in time and automatically switch to the vehicle's pre-crash handling mode.
Safety warning system fully monitors vehicle status
In addition to the control and handling of collisions and vehicle speeds, advanced vehicle active safety systems can also monitor the driving behavior of the owner and the quality of the tires through various sensing systems and make warning actions. These safety warning systems include driving danger warning systems, visual blind spot warning (or blind spot detection) systems, and automobile tire pressure monitoring systems.
Most of these warning systems use various sensors for monitoring, and determine whether the behavior of the vehicle or driving is safe through a set of identification systems, and issue appropriate warning signals in due course.
The driving hazard warning system uses image sensors to monitor the driver's behavior. When the driver appears to be dozing off or the line of sight is too far away from the lane, the system will issue a warning. Some systems even monitor the concentration of alcohol in the car and issue appropriate warnings.
In addition, because the driver's line of sight has many blind spots, the visual blind spot warning system will provide the driver with environmental information about the blind spot through the sensor installed at the rear of the vehicle. For example, the use of CCD digital sensors or ultrasound to monitor, visualize and warn behind objects can avoid accidents when the vehicle is backing.
The car tire pressure monitoring system is also an active safety system. This system can send the tire pressure signal to the display on the driver's platform through the built-in sensor placed on the tire, allowing the driver to monitor the tire pressure in real time during driving . When the tires show signs of danger, the system will alarm in time to avoid tire puncture during high-speed driving.
A notable phenomenon is that although pre-collision systems, adaptive cruise systems, and safety warning systems and other automotive active safety technologies are gaining more and more attention, the owners of these technologies represent automobile manufacturers such as Mercedes-Benz, Toyota, and Volvo. A small number of high-end models are equipped with such systems, but we can already see the expected picture of the upgrade of car safety systems.
