Car East April 24 news, recently, the "non-conformity comment" channel uploaded a test video of Porsche's InnoDrive system in youtube, which mainly tested Porsche's adaptive cruise system and lane keeping function, but the results were not satisfactory.
During the test, tester Kyle found that the Porsche Taycan 4 Cross Turismo did not drive well after turning on the adaptive cruise system, and after turning on the lane keeping function, the car would also touch the lane lines on both sides from time to time. Only in terms of safety, the car's driving system is ok.
During the test, tester Alyssa also compared Porsche's adaptive cruise system and lane keeping function with Tesla's, believing that Tesla's system was more robust.
First, the adaptive cruise system has limited functions, and the lane remains unstable
During the evaluation, Kyle and Alyssa found that the Porsche Taycan 4 Cross Turismo's driving system was not equipped with tracking the driver's safe eye movements, nor was there an eye tracking function for untouched steering wheel behavior.
In addition, during the driving, they also found that equipped with an adaptive cruise system can only be achieved using a pre-drawn highway map to achieve adaptive cruise function. In addition to this, the system will not be available in other environments.
When displaying planned lanes, the user can only see the lanes that are going straight, and cannot see the vehicle conversion process at the time of the turn. And during the driving process, the dashboard can not indicate the surrounding car driving situation, can not help the driver to understand the surrounding road conditions.
▲When turning, only the straight lane is still displayed on the dashboard
In addition, porsche adaptive cruise systems performed well in the automatic function evaluation session.
When accelerating and cornering, the Porsche Taycan 4 Cross Turismo adapts to the speed limit and gradually shifts to the speed limit. However, in the process of driving in a straight line, porsche adaptive cruise system does not play well, dangling in the middle of the lane. Kyle and Alyssa joked that it was a bit like drunk driving, being found by the traffic police, and that points were to be deducted.
In addition, during the operation of the adaptive cruise system, the driver changes the vehicle to the left lane, and the vehicle always automatically changes to the right lane, and the flexibility is not very strong.
▲The vehicle is erratic when going straight, and the driver adjusts the steering wheel
Second, there are some safety tips, but the system is detached without warning
In terms of safety, porsche driving systems show a high level of safety, but there is still a lot of room for improvement in some hazard warnings.
During the test, the tester simulated a situation where the vehicle issued a warning but the driver did not take over in time. In this condition, the system jerks the driver's seat belt and brakes with a "Didi" alarm sound. After the vehicle is stopped, the system detects that there are no vehicles around, judges the current state of safety, and automatically opens the adaptive cruise function to continue to control the vehicle to drive forward.
▲The system violently pulls the driver's seat belt
However, when the driver releases both hands, the system does not prompt the driver to pay attention to safety and hold the steering wheel. In addition, in the process of driving, in the case that some systems cannot be fully judged, the system also fails to remind the driver to take over in time, which has a large safety hazard.
In addition, Porsche Automatic Cruise does not do a good job of user warnings when the system is automatically disengaged and when the system is disengaged, and if the driver is not attentive, there is a high probability of accidents.
Conclusion: Porsche's autonomous driving function needs to be improved
As a luxury car brand, Porsche's high-end brand image has been deeply rooted in the hearts of the people, but in terms of car intelligence and electrification, it is obvious that Porsche is slowly lagging behind.
Not only in the automatic cruise system, Porsche is much different from many car companies, and Porsche is not doing a very good job in lane keeping. It can be said that Porsche did not exert the technical strength of an established car company.
Porsche is the time to wake up, the current car market is not the past as long as the brand is not worried about selling the market, and then it is not easy to overcome the technology, and it is only sooner or later to be eliminated by emerging car companies.
