These automotive safety technologies have been developed to meet your autonomous driving needs

Recently, Tesla's Autopilot autopilot function has been in succession, causing doubts about the safety of the Autopilot function. Tesla also said many times that in most cases, the driver abused the Autopilot autopilot function and caused the accident. To reduce the possibility of similar accidents, Tesla will introduce a new Autopilot safety alert System. In the new system, if the driver does not respond within 15 seconds of the warning, the automatic steering system will end the work and a warning will be issued again asking the owner to hold the steering wheel with both hands. The new safety alert system not only protects the driver after the Autopilot system is activated, but also prevents the driver from intervening after the system has stopped working. The driver cannot activate the Autopilot system until the vehicle is fully braked and the gear is engaged in the parking gear. At present, this constraint seems to only affect the automatic steering function, and Traffic Aware Cruise Control (TACC) will continue to work.

These automotive safety technologies have been developed to meet your autonomous driving needs. Nissan Improves ProPilot Autopilot Technology

Recently, Nissan revealed that it will improve ProPilot semi-automatic driving technology and plan to achieve automatic driving at the intersection by 2020. ProPilot technology can be easily turned on or off by buttons mounted on the steering wheel, and the car has a personal display that shows the vehicle's operating status. The driver can preset the speed between 30km/h and 130km/h (approximately 18 mph to 81 mph) and the system will automatically drive at a preset speed.

If the vehicle in front stops, the Nissan ProPilot system will automatically brake, allowing the vehicle to stop completely and maintain a safe distance from the vehicle in front. The ProPilot system also automatically maintains the direction of the car on the traffic road, keeping the vehicle in the middle of the lane. Nissan's ProPilot technology requires drivers to put their hands on the steering wheel to keep track of road conditions. This means that if there is a problem with semi-automatic driving technology, the driver can receive a reminder and quickly take over.

Denso development image recognition technology

Denso Group has developed a technology that uses a single-eye camera to quickly and accurately recognize a person's body orientation, height, and distance from a car. It has been experimentally confirmed that in the demonstration environment of the analog in-vehicle device, the processing time is only 56 milliseconds. Denso intends to apply this technology to automotive ADAS (Advanced Driver Assistance Systems). When identifying multiple features, the amount of data processed is large, so it is difficult to perform real-time processing using the original method. Denso shortened the calculation time by adjusting the image data. At the same time, the amount of calculation is also reduced to about 1/10 of the original, and can also be used on on-board semiconductors with limited computing power.

Adjust DNN to meet ADAS requirements

The technology was developed by Denso IT Laborator, a subsidiary of Denso. The image recognition algorithm uses a kind of deep learning - DNN (Deep Neural Network).

Previously, image processing was performed using a combination of Directional Gradient Histogram (HOG) and Linear Support Vector Machine (SVM), but only a simple judgment was made in the image. Since a plurality of feature quantities cannot be obtained in parallel, it is impossible to determine the state and attributes of pedestrians such as the direction of the pedestrian and the distance from the vehicle.

The newly developed image recognition method uses DNN to process a plurality of different information in an image in parallel. Improved the method called "Image Pyramid" to improve processing speed. The original image recognition ensures the recognition accuracy by repeating the "reduction resolution-recognition" process of about 20 to 30 times. This time, by reducing the number of cycles to 2 or 3 times, the amount of calculation is reduced.

Continental 24GHz radar technology avoids collision with side cars

At the TechRide 2016, a technical test drive for the news media on September 14th, the Continental Group demonstrated the technology of avoiding collisions with side cars at intersections. The front bumper is equipped with a 24 GHz radar on the side and automatically brakes when it detects a vehicle that is likely to collide.

The vehicle used in the test was Volkswagen's "Golf", and a 24 GHz band radar was installed inside the side of the front bumper. ACC (Adaptive Cruise Control) and the automatic millimeter wave radar used in the automatic braking system have a detection distance of up to 200 m, but the detectable angle is only about 90 degrees, so it is difficult to detect the vehicle coming from the left and right direction. Therefore, the 24 GHz band radar mounted on the bumper has selected products with a detectable angle of 150 degrees. Although the detection distance is only 60m, it can detect a wide range of obstacles, so you only need to install one on each side.

The test hypothesis on the test road is that when the car enters the intersection with poor visibility, the vehicle comes from the right. The car enters the intersection at a low speed. At this time, there are vehicles on the right side that pass through the front and cross the road. If you move on, you will hit the side of the right side of the car. However, the 24 GHz band radar detects the right side of the car in advance, the automatic braking system starts, the car stops, and the vehicle that is crossing the road continues to pass the front of the car.

In this demonstration, this function was implemented using only radar, and the camera was not used. It is possible that the radar of the 24 GHz band cannot be used in the future, so it is estimated that it will be replaced with a large detection angle radar of the 77 GHz band when it is put into practical use.

A new breakthrough in the automatic driving technology of WABCO OnGuardMAX system

WABCO, the world's leading provider of safety, efficiency and smart interconnect technology for commercial vehicles, has introduced the OnGuardMAX® Advanced Automatic Emergency Brake System (AEBS) for trucks and buses. The system provides full braking when encountering a stationary and traveling vehicle ahead. WABCO is the industry's first independent system supplier to offer AEBS, and the launch of the OnGuardMAX system marks another breakthrough in commercial vehicle autopilot.

WABCO's OnGuardMAX is equipped with the most advanced 77GHz radar and high-resolution camera to detect a collision with the vehicle in front and to alert the driver with obvious audible, visual and tactile warnings. For example, when entering a traffic jam, if the driver does not take appropriate corrective action, the OnGuardMAX system will perform a full brake to bring the vehicle to a complete stop as it approaches the stationary and traveling vehicles.

Even under low visibility conditions, the OnGuardMAX system maintains high precision operation and meets global AEBS regulatory standards. In addition, the OnGuardMAX system has a lane departure warning (LDW) feature that complies with relevant government regulations that are currently in effect or are about to take effect. The OnGuardMAX system also has the ability to achieve full braking at high speeds.
