In general, car sensors can be used to predict whether a high-speed vehicle will crash. Ordinary radars may not be able to prevent problems in the event of scratches at low speeds or accidents at low speeds due to driver blind spots. A few days ago, parts supplier Continental Group developed a touch sensor system with voice recognition function. Based on the received sound signals, the system can detect low-speed contact between the vehicle and people or objects, and feedback to the vehicle to guide the vehicle. Take emergency braking action.
Accidental scratches that may be caused by vehicles at low speeds often have specific sound characteristics, so the contact sensor system can detect the vehicle surroundings in real time through voice recognition. This system is mainly suitable for situations where pedestrians or objects are close to the car, but do not enter the detection range of other sensors (such as on-board radar). In addition, the touch sensor system can also authenticate the driver, and the certified driver can activate the automatic door opening function even if he taps the door.
This sensor developed by Continental can detect the sound of a physical collision. The sensor can adjust low-speed contacts and make different responses based on the sound signal mode. In the future, the touch sensor system will also provide additional signal paths to detect sounds around the vehicle, such as underwater sounds. This technology will have important implications for the development of autonomous vehicles.
Considering safety factors, judging from the current development level of autonomous driving, mainland's new sensor technology may come out in 2022. This technology will help to further ensure the safety of the vehicle and avoid accidents that are difficult to detect, such as low-speed scratches and escapes.
