Background

At present, many vehicles have certain automatic driving functions, such as lane keeping ACC at high speed, and cruise at high speed is realized based on automatic driving of a number L3 of some factories. In addition, when a low-speed automatic driving system such as automatic parking is used, the driver can still be in the seat when the driver needs to park, but the system can complete the parking action in the whole process.

However, a common problem of these automatic driving functions is that the driving habit of the driver is not considered, which results in the following two problems:

the safety of the system use is reduced. For example, for an automatic parking system, how to design a reasonable vehicle speed for parking is an engineering problem. However, too high may cause the driver in the vehicle to become strained and near the obstacle. Even if the system is safe and can be stopped before an obstacle, the driver can intervene in the system due to the tension of the driver, such as taking over or braking, so that the system falls down and unsafe results are caused. In addition, in a high-speed scene, when a vehicle cut-in arrives at the lane or two lanes arrive at a large truck, the tension of the driver can cause intervention, and unsafe conditions are caused.

The experience of the system usage is reduced. For the same reason, even if the vehicle is eventually successfully taken over by the driver, the overall experience is poor.

The fundamental reason for the above problems is that the design of these autopilot systems may take into account the statistical experience and experience of the driver, but fails to customize the individual drivers so that these problems cannot be solved effectively when the individual drivers use these systems.
