2019 most worthy of the top 10 automotive technology
Electronic exterior mirror
The replacement of the rearview mirrors by the camera has not only stopped at the concept car, but also the production of the McLaren Speedtail and Lexus ES. Compared to traditional exterior mirrors, the camera offers a wider field of view and lower wind resistance (the McLaren Speedtail can be retracted to the body in speed mode to reach a top speed of 400km/h). In addition, the electronic camera can avoid the blind spot of the traditional exterior mirror and enhance the safety of the new car. At present, most countries' regulations do not allow the use of this technology, but believe that it is only a matter of time before release.
Head-up display (HUD)
A Japanese company can use a film containing a photoreactive material to cover the windshield. A laser projector mounted on the instrument panel can activate the material so that the windshield can display navigation, speed, speed, warning lights, etc. Key Information. Combined with the body sensor, the driver can more intuitively detect pedestrians, wild animals, etc. on the road, identify potential risk factors and make driving safer.
The maturity of 5G communication technology will enable real-time networking between vehicles and vehicles, vehicles and roads, vehicles and people, vehicles and the Internet. Through the body sensor and road information collection system, massive data will be generated and efficiently transmitted through 5G technology. , and low latency in high-density vehicle scenarios, enabling the Internet to properly monitor, schedule, and manage cars, people, roads, and objects.
In 2018, Orbis brought a very aggressive hub motor system, giving up the previous central motor solution, but biasing a small, light, low-torque motor to drive the wheels by driving a ring gear. The new hub motor greatly reduces the unsprung mass. This wheel hub motor system was modified on the Civic Type R to make the Type R a four-wheel drive with enhanced performance.
L3 level driverless
Compared with the L2-class driver who is already more common at this stage, the driver of the L3 vehicle can take a break, remove the attention from the road environment, and do his own thing. The driver needs to take over when the vehicle needs it. Although the Audi A8L can now achieve automatic driving at 60km/h, due to restrictions in policies and regulations, this configuration cannot be introduced in the domestic market. With the gradual maturity of autonomous driving technology, regulations are expected to be further liberalized.
Electric car wireless charging
Wireless or inductive charging technology can effectively improve charging efficiency. Induction uses a magnetic field to transfer electricity from the charging pad to the car, which is as efficient as wired charging. Wireless charging boards from the mainland and WiTricity transmit up to 11 kilowatts (6 to 7 kilowatts is the typical power of today's public communication equipment).
Attention assist system
The attention monitor in the Cadillac Super Cruise System uses an infrared camera to monitor the driver's line of sight. If the driver's line of sight leaves the road ahead for more than three seconds, the system will alert you to the safety of the vehicle. If you ignore the warning for a long time, the vehicle will even slow down and stop.
Underground data mining
Wvesense's HF ground penetrating radar reads the unique patterns of underground pipes, rocks and roots like fingerprints to help vehicles understand their exact location in the world. It was developed by MIT and used by the US military in Afghanistan to ensure that it travels exactly along the road on roads covered by sand. In the future, this technology can help vehicles to travel in extreme environments and solve the problem of ground driving safety covered by snow and sand.
After electrification steering and suspension electrification, the brake system will also introduce the call extrusion technology. The remote brake sends a signal from the pedal to the electric actuator. The electric actuator pushes the hydraulic oil into the caliper. Compared with the pure hydraulic system, the weight can be reduced, the response is more agile, and the flexibility can be adjusted. The feel and response of the pedal can be adjusted according to the driving mode, and the switching between the regenerative braking and the friction braking of the electric vehicle can be improved.
Magnesium is not widely used in automotive materials applications, but the new super magnesium will change this. Super magnesium is lighter than aluminum, but it is stronger than aluminum and costs half as much as carbon fiber. Compared with existing magnesium alloys, super magnesium has better corrosion resistance, weldability and multidirectional strength when mixed with rare earth metals. Although its price is currently 20% to 35% more expensive than aluminum, with the large-scale production of super magnesium, the cost will gradually decrease. This metal can be cast, forged or extruded for applications ranging from suspension links to valve body components.
