On August 30th, local time in the United States, Waymo announced that the mileage of self-driving cars on public relations roads reached 9 million kilometers, and the simulation test mileage exceeded 5 billion miles.
Here, I mainly want to talk about the situation of Waymo self-driving cars on public roads, especially when the US media reported that the road test of Waymo self-driving cars caused a lot of confusion to local drivers. Facing the coming wave of autonomous driving, human drivers are facing the problem of how to coexist peacefully with unmanned vehicles.
As the world's first company to conduct self-driving car tests on public grounds, Waymo has accumulated more test mileage than all competitors. Since entering 2018, Waymo's test mileage has been accelerating.
From the figure below, we can see that Waymo tested 5 million miles in February 2018, and then increased at a rate of one million miles every two months. After June 2018, it will increase by one every month. The speed increase of millions of miles, this kind of growth curve is really wonderful for autonomous driving technology.
Apple’s current CEO Tim Cook once said that self-driving cars are the mother of all artificial intelligence projects. This sentence suffices to explain how difficult it is to implement autonomous driving technology that uses deep learning and artificial intelligence. However, in the case of public road testing, it can provide basic data for deep learning and simulation environment testing. The more mileage tested, the more data available for learning and simulation environment testing, and the more beneficial it is Improvement of autonomous driving technology.
In addition to testing autonomous driving technology through accumulated mileage, Waymo is also testing the construction of the operating system. After all, after the role of the driver is replaced by robots, some services that require manpower have to be supplemented by other positions, such as technical maintenance and manual labor. Customer service and so on,
The test of the entire operating system may affect a small number of people and positions, and the test on public roads will affect other drivers on the road, including human drivers or unmanned vehicles of other companies. At present, there are no reports of conflicts between unmanned vehicles. However, there are many conflicts between unmanned vehicles and human drivers.
Human drivers and unmanned vehicles must learn to live with each otherThe most fierce conflict between unmanned vehicles and human drivers is the occurrence of traffic accidents. The majority of the reported traffic accidents between the two are human drivers. In fact, in addition to the division of responsibilities between the two parties at the scene of the accident, for traffic accidents caused by autonomous vehicles, there is also a problem that is, if it is the responsibility of the driverless car, then whether the responsibility belongs to the technical party or the vehicle owner.
However, such a fierce conflict as a traffic accident is a small probability event after all. The conflict between unmanned vehicles and human drivers is more of a similar reported conflict on driving habits. Human drivers’ complaints about Waymo’s self-driving cars are mainly about turning or merging, which requires a long judgment time, or sometimes forget to turn on the turning lights when turning.
This conflict is not a conflict between the two driving principles. Autonomous driving technology is developed based on the existing transportation system, and human drivers also drive vehicles under the existing transportation system. The reason for the conflict is that they are not familiar enough with each other. And mutual understanding, human drivers cannot understand the state of self-driving cars.
In order to solve the communication problem between humans and self-driving cars, Ford followed a row of indicator lights on the outside of the car, and Wu Enda’s drive. ai uses the display screen to broadcast on the outside of the car to strengthen the communication between humans and self-driving cars. This kind of communication is necessary, whether it is self-driving cars and human drivers, or self-driving cars and passersby.
With the maturity of autonomous driving technology, there are more and more autonomous vehicles on the road. Human drivers and autonomous vehicles must learn how to coexist with each other.
Electronic Lock Motor product introduction:
Electronic Lock Motor, also known as Intelligent lock motor, Belong to small reducer series, the main structure composed of drive motor (motor) with a reduction gear box, composed of a shaft connection, form integrated motor reducer; Drive motor is purchasing product, reduction gear box is customized according to the project product demand, the maximum power under 10 w, maximum voltage up to 12 v, below 25 mm diameter size.
Functions: it is widely used in various intelligent locks, such as Shared bicycle lock, fingerprint lock, glass lock, safe lock, hotel lock, family lock, inductive smart lock, etc
Features:China Electronic Lock Motor is based on micro precision reducer development, small intelligent micro precision reducer can do 10 mm in diameter, is widely used in safe, locks, smart locks, sensor intelligent lock;
This kind of motor has the characteristics of low noise, low energy consumption, small volume, light quality, high precision, large torque and durability
Method of use: the best stable in horizontal plane, installed on the China Electronic Lock Motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc Electronic Lock Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Electronic Lock Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a electronic Lock Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
China Electronic Lock Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Electronic Lock Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
