No Collision: Analysis of Volvo's New S60 Safety System

As we all know, Volvo has always been famous for its safety. The new S60, which debuted at the Geneva Motor Show, not only innovated the style of the car, but also made new achievements in active safety. It is not difficult to see that Volvo has not forgotten their promise to protect the lives of consumers.

Advanced integrated braking function

This advanced braking system is an important component of Volvo's new S60 dynamic driving system, ensuring that it can brake in the shortest distance under all road conditions.

The braking system includes Ready Alert Brakes, which slightly tightens the brake calipers before the driver brakes when an emergency is predicted, thus shortening reaction time. Hydraulic Brake Assist also intervenes in emergency situations. If the driver's braking force or speed is insufficient, it will increase the braking force by controlling the ABS to ensure the shortest stopping distance. Complementary to this is Optimized Hydraulic Brakes, which can hydraulically compensate for the vacuum pressure in the brake booster during full braking to increase braking force. In addition, there is Fading Brake Support technology. In long-distance, high-intensity braking, the braking system will show a phenomenon of fading effect due to rising temperature. The application of fading compensation technology will gradually increase the brake pressure in this case, thereby reducing the negative effects of thermal fading.

Pedestrian Detection System

This groundbreaking pedestrian detection system is the core part of the new safety technology. Combined with automatic full-force braking, it can be said to be keeping up with the trend of the times and building a new "harmonious society" between pedestrians and motor vehicles.

This system is mainly composed of radar and camera. A dual-mode radar is integrated on the front grille of the new S60, which is responsible for detecting the position of all objects within the working range; the camera integrated on the back of the rearview mirror will transmit the captured image to the central processor to determine the type of object. In addition, since the newly adopted radar has a wider detection range than traditional radar, it can detect pedestrians beside the lane in advance. The high-resolution camera can not only collect images, but also capture the posture of pedestrians for processor analysis. With these data, the new S60 has transformed from simply sensing pedestrians to a "magic weapon" that can predict whether pedestrians are likely to enter the lane.

The camera on the back of the rearview mirror can distinguish the type of object

If the radar and camera sense danger at the same time, the driver will be alerted through a warning sound and a warning light on the head-up display, and the brake calipers will be pre-tightened.

The radar integrated into the grille is responsible for detecting the distance of objects.

Thomas Broberg, Volvo's senior safety advisor, also said that thanks to these new sensors, the new S60 can detect all objects over 80 cm high, which means that even children walking on the street will not be missed.

With the information from the detection system, the automatic full-force braking device can show its skills. If the radar and camera both feedback the information of dangerous situations, the new S60 will issue a warning sound and flash a warning signal on the head-up display system located on the front windshield. In order to conform to the driver's instinctive reaction, Volvo also designed the warning signal to imitate the style of brake lights. However, if you ignore these warnings, the automatic full-force braking device will intervene in time. This setting can almost completely avoid the occurrence of car accidents when the speed is less than 34 kilometers per hour; if it exceeds this speed, the speed will be reduced as much as possible to minimize the danger and possible losses.

However, although the resolution of the camera is not low, it has limitations just like the human eye. When in foggy or low-light conditions, the camera also has difficulty accurately identifying objects.

City security system

Although the city safety system of the older XC60 seems a bit bland compared to the technologies mentioned above, it is still used as standard configuration on the new S60. This includes functions such as fatigue driving warning, blind spot warning, and of course, things like steering-activated headlights.

Among them, the more interesting one is the Lane Departure Warning function. It is said that when the vehicle changes lanes without turning on the turn signal, the system will sound a warning to remind the driver. Speaking of this, we can't help but worry about Volvo. This technology may make most "domestic" drivers who like to change lanes without turning on the signal feel annoyed, right? But then again, although the safety system of the new S60 has provided insurance for our driving safety, we are the ones driving after all, and a little more caution and good driving habits may be more effective than any safety system.
