Problems solved by technology

As the "eyes" of the entire autonomous driving system, the sensor plays a vital role in the safe operation of the function. It is not too much to design redundantly for the perception system. At the same time, cost optimization is also a practical problem that has to be considered, and the industry has not given a good solution in this regard.

Embodiment Construction

[0038] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] The present invention is aimed at L3 automatic driving, and the design operation area is limited to congested working conditions under structured roads such as expressways and urban expressways, and the design operation speed is limited to ≤60km / h. The driver does not need to implement online monitoring of the driving environment, but needs to be able to respond to the system's takeover request in a timely manner when the system prompts to take over.

[0040] see figure 1 As shown, this embodiment discloses a laterally aware safe driving control method based on L3 automatic driving, including the following steps:

[0041] (S1) Obtain lateral sensing data through the sensing module 1, and control the vehicle to drive in the lane; wherein, the lateral sensing data includes lateral target information, roadside / guardrail information, and...
