With the advancement of high technology, human beings are researching some high-tech technologies for automobiles, such as driverless, 360-degree panoramic images, tire monitor sensor, blind spot monitoring, lane keeping, adaptive cruise, wireless tire pressure monitoring system, etc. These high-tech technologies can make you more handy when driving. Next, let's talk about six most advanced safety systems.
The lane-keeping assist system is one of the intelligent driving assist systems. It is based on the lane departure warning system (LDWS) to control the brake control coordination device. The lane-keeping assist system can help vehicles keep driving safely in the preset lanes. The concentration of driving increases with the speed of the car. Running on the high-way is definitely the most troublesome. Sometimes there is often a mental dissipation. Although it is only a few seconds, it is really dangerous. Whether it is cruise control, adaptive cruise, or this lane-keeping assist system, it is actually an auxiliary means to help the driver improve safety.
The FCW system can constantly monitor the vehicle in front through the radar system, determining the distance, orientation and relative speed between the vehicle and the preceding vehicle, and warning the driver when there is a potential collision hazard. The FCW system itself will not take any braking measures to avoid collision or control the vehicle. If the vehicle is too close to the vehicle in front during driving, the warning light at the front windshield will continue to flash to remind the driver. If the vehicle continues to approach, the driver has not taken braking measures, the warning light flashing frequency and the brightness are further enhanced, and the alarm sounds. At this time, the collision warning system will also intervene in the braking system to actively brake the vehicle, thereby reducing the accident injury rate.
The adaptive cruise control system is a new system that adds a control function to maintain a reasonable distance from the front vehicle on the base of the system that performs cruise control at a set speed. According to the information detected by the vehicle distance sensor, and the vehicle's driving route information determined by the vehicle's speed sensor and the yaw rate sensor, it is determined whether there is a vehicle driving ahead on the same lane of the vehicle. The distance sensor uses microwave radar or range radar. When there is no vehicle in front of the same lane, the car drives at the set speed like normal cruise control. When a vehicle appears in front of you, the car drives at a speed lower than the set speed to control the reasonable distance between the vehicle and the vehicle in front. An intelligent car equipped with an adaptive cruise control system uses radar and a computer to identify whether it is a bicycle, a car, or a pedestrian that is close to the vehicle to control the driving state of the vehicle according to road conditions, completely or partially replacing the driver's operation.
Crossroads and intersections are locations where traffic accidents occur frequently. In response to this situation, many manufacturers have introduced this system. When you change lanes in reverse, it can detect potential objects in the rear and give warnings. Especially in road conditions with extremely low visibility, the assist system can even assist the driver.
The blind-spot warning system is a key function in the driver assistance system, covering 360° road conditions around the vehicle body at low speed. The active safety loop detection system also includes adaptive cruise control, tyre pressure sensor, lane departure warning, parking sonar, tpms tyre pressure monitoring system, etc. Some driver assistance systems make your driving safer, especially when driving for long periods of time. Detect the relative position of the vehicle behind the adjacent lane and the own vehicle through the cameras on both sides of the rear of the vehicle. When there is a vehicle in the blind spot area, the small light on the exterior rearview mirror will light up to warn the owner of the collision with the blind spot vehicle or pedestrian when changing lanes. When the user pours the car out of the parking space, the system will detect if there is a vehicle passing behind and alert the driver.
AEB is an automotive active safety technology, mainly composed of three modules: ranging module, data analysis module and actuator module. The core of the ranging module includes microwave radar, lidar and video system, etc. It can provide comprehensive, accurate and real-time image and road condition information of the road ahead. The AEB system uses radar to measure the distance to the vehicle in front, and then uses the data analysis module to compare the measured distance with the alarm distance and safety distance. When the distance is less than the alarm distance, an alarm prompt is given, and when the distance is less than the safety distance, even when the driver has no time to step on the brake pedal, the AEB system will also be activated to automatically brake the car, thereby escorting for safe travel.
In addition, TPMS system is also listed as one of the major safety systems for automobiles. The tyre pressure monitoring system was installed in the United States in 2003 and the European Union began to install it in 2014. When the tires are stuck, the tire pressure is too high or too low, the temperature is too high, etc., we can not judge the hidden consequences, at this time, the function of pressure monitoring system or the smart tpms sensor is to monitor tire information in real time to ensure our driving safety.
