After the emergence of the Tesla driverless death accident, a wide-ranging discussion was held on the safe application of driverless technology. Some analysts believe that Google has entered the development level of the highest level level 4 in the development of driverless technology (that is, there is no steering wheel in the car, no driver intervention at all), because there are drivers in the low-level driverless technology. Human intervention, and people can not remain focused all the time and lead to increased risk.
In order to improve the safety of driverless technology applications, some measures must be taken. For example, to increase mutual understanding between people and unmanned driving, the vehicle can clearly know the state of the person, and the person can clearly know the range of the ability of the driver; for example, in addition to the sensor of the vehicle itself, it is also dependent on other communication equipment. The data assists in judgment and decision making. Only in this way can unmanned driving to take advantage of its real advantages.
In general, the following five things should be started now.
Control automatic/manual switching time between 10 and 15 seconds
Vehicles that currently have ACC, LCA or even blind spot detection and front-alarm assisted brakes are actually equivalent to driverless when driving on a highway. Manual intervention is required only in the event of an unforeseen system failure, so these techniques often require the driver to put his hand on the steering wheel.
When the vehicle receives the signal that the driverless function is released, it will sound a warning tone after 10 to 15 seconds, and after 5 seconds, exit the lane keeping assist function and switch to the manual driving state. Some manufacturers set the switching time to 1 minute or longer for the driver to reserve enough preparation time, which is enough to climb the self-timer video in the back seat, and the driver is in such a long switching time. It may not be able to concentrate and may even fall asleep.
In fact, setting the switching time to 15 seconds is sufficient. The driver can use this 15 seconds to connect the smart phone, turn around and grab the schoolbag from the back seat or grab a message to send a message (of course these two things should not be done).
Must teach the user to know what unmanned cars can't do
Tesla Autopilot has been successful in marketing strategy, but so far it has been over-committed in terms of practicality, even if it launched a "beta" version. In fact, the user needs not the "user litigation cost commitment" after the problem occurs, but the manufacturers and dealers carry out rigorous technical training for the users, so that the users of the vehicle fully understand all the technical features of the new car, such as the new initiative. Safe driving assistance technology, human-computer interaction system and car navigation system.
Then the problem came out. Although the car sales staff is skilled in sales techniques, they generally don't know about car technology. If a salesperson knows the technology well, he may find another way out without having to hang on to a 60-hour sales job this week. At this time, some new training methods are needed. For example, some manufacturers will provide sales personnel with technical training for users. Some dealers will assign special personnel to answer technical questions for customers (of course, if these people accumulate technology to a certain extent, they will naturally find another job). Some sellers will attract customers to participate in technical training by giving away gift vouchers, and users will receive technical training through online video and built-in video of the car after buying the car. This is a good start.
Use cameras and radars to work together to monitor parallel vehicles
When the vehicle with the adjacent lane is ready to be merged into the lane you are driving, the ACC system takes about 1 second to lock the parallel vehicle and slow down your vehicle. This process will give drivers and passengers a more thrilling experience, especially during long-distance highway travel, this scene will happen from time to time.
The camera mounted on the windshield is used to control lane keeping assist, automatic far and near light switching, front collision warning and other systems. It can monitor the vehicles in the front lane of your car. The cooperation between the central controller and the ACC can reduce the time taken to take braking measures by a fraction of a second. This means that a car with this function has been upgraded from Unmanned Technology Level 1 (ie one or more assisted driving functions to work independently) to Level 2 (ie multiple assisted driving functions work together), in the next few years, this It will be an effective solution to help drivers improve their driving experience during commuting or long-distance travel in large cities, reduce physical and mental consumption, and prevent distractions from causing accidents.
Increase fatigue driving warning function
With the help of a lot of accessibility features, you may not have to focus your attention on driving. But before the driverless technology is upgraded so that you have enough time to take over the control of the vehicle, you still need to be vigilant, instead of going to a nap or WeChat chat.
At this point, the fatigue driving warning function can help. The initial design of the technology was complex, including a camera for monitoring the state of the human eye, an instrument for monitoring breathing and heartbeat, etc., but later the technician found that when the driver put his hands on the steering wheel, The driver's attention can be judged by monitoring subtle changes in driving behavior. At the same time, the vehicle can also determine whether the vehicle deviates from the driving lane through the information captured by the LCA system.
