October 12, 2011, the United States TRW (Tianhe) Automobile Holdings announced that the company developed two technologies: one is a new generation of hybrid tire pressure monitoring system (TPMS), with a combination of sensor technology to provide automatic positioning The other is a senior pedestrian detection system with automatic emergency braking.
The new-generation hybrid tire pressure monitoring system measures the air pressure and temperature inside the tire through a basic direct tire pressure monitoring sensor mounted on the wheel, combined with vehicle ABS anti-lock braking system or ESC electronic stability control wheel speed sensor data. The automatic positioning function informs the driver which tires are in a low pressure state.
The advantage of the tire pressure monitoring system is that it has an advanced automatic positioning system that eliminates the need for additional electronic hardware that was previously used to position sensors. In addition, the receiver can be configured inside the vehicle to reduce the cost of the housing. This is the most economical type of automatic positioning system currently available.
Similar to TRW's existing direct tire pressure monitoring system (dTPMS), this technology consists of four basic sensors mounted on wheels to directly monitor a single tire pressure level, eliminating the need for additional sensor electronics for positioning. The receiver is usually fitted in the passenger compartment and uses the data from the tire pressure monitoring sensors and the vehicle ABS/ESC sensors to identify where the tire pressure is lacking.
At present, TRW supplies its customers with an indirect tire pressure monitoring system. Direct tire pressure monitoring is the best technology solution for ensuring tire safety, reducing CO2 emissions, and improving fuel consumption. Given the existing or potential mandatory regulations in Europe and Asia, the market for this product will continue to grow over the next five to ten years, and TRW will continue to develop the dTPMS technology portfolio to provide customers with more affordable solutions. The new hybrid tire pressure monitoring technology announced this time is an important step in this direction. TRW expects that the hybrid TPMS system will be put into mass production in 2013.
Another newly developed technology is the forward-looking pedestrian detection and accident mitigation system. It uses advanced signal processing algorithms to fuse video camera data and radar sensor data, and combines electronic stability control (ESC) to achieve automatic braking, helping to reduce the severity of pedestrian injuries.
In the event of a collision between a pedestrian and a vehicle, there is a high risk of serious injury or death. According to statistics, when the speed of a vehicle is 40 mph, the pedestrian crash rate is 85%; at 30 miles per hour, the mortality rate is 45%; at 20 mph, the mortality rate drops to 5%. The active pedestrian detection system can automatically decelerate the vehicle, reduce the collision speed or even avoid collisions, which can significantly improve the survival rate of pedestrians.
TRW's forward-looking pedestrian detection system fuses adjustable-level video camera sensor information with 24 GHz radar data. When the camera detects pedestrians in front of them, the system will use a sophisticated risk assessment algorithm to determine the collision probability after being confirmed by the radar to warn the driver and automatically activate the braking function to decelerate the vehicle and reduce the severity of the collision. The system is in line with TRW's production of radar-based emergency braking technology.
In addition to detecting vehicles, lanes, and identifying traffic signs, adjustable-level cameras also have the ability to detect and track pedestrians within 40 meters and can work in complex urban traffic conditions, such as detecting crowded sidewalks or umbrellas in rainy weather. pedestrian. By adding radar and speed sensor fusion technology, system performance is improved and full braking at higher speeds is achieved.
This new pedestrian detection technology can be used in conjunction with TRW's pedestrian protection system. Sensors mounted on the front of the vehicle detect actual pedestrian collisions and activate active safety devices, such as car hood opening functions that reduce collision damage, and improve collisions. Pedestrian safety protection. TRW expects to mass-produce a forward-looking pedestrian collision mitigation system with full braking capability in 2014.
