This article mainly describes the application of sensors such as lidar, green laser pointer, millimeter wave radar and camera in the current ADAS, the future of L4/L5 autopilot systems and the trend of multi-sensor fusion solutions.
The sensor is in rapid iteration. At present, with the continuous increase of the penetration rate of the ADAS function module, the demand of the sensor market will be mainly driven by the camera and the millimeter wave radar in the short term; while the Audi A8 of the L3 level automatic driving is mass-produced to the entire automobile industry, the automatic driving The process is earlier than expected, and each sensor and control system is rapidly iterating; before and after 2020, the L4-level autopilot production is on the road, and the market for laser radar will expand rapidly.
Due to the characteristics of each major sensor, a single type of sensor is not suitable for the complex situation and safety redundancy of the L4/L5 fully automatic driving. The multi-sensor combination solution will be inevitable. In 2030, the global automotive sensor market will exceed 50 billion US dollars.
Lidar is developing toward miniaturization and integration. Lidar: 3D environment modeling makes it a core sensor, but performance is degraded in bad weather, and the image and color cannot be recognized as its short board; in L3 and above sensor solutions, at least one laser radar is required; Transition to hybrid solid state and pure solid-state laser radar. With the expansion of mass production scale and technical iteration, the cost is rapidly decreasing. Lidar is also developing toward miniaturization, low power consumption and ASIC integration. At present, foreign manufacturers are successively It is developed in cooperation with the first-tier suppliers of auto parts. If domestic manufacturers have the ability to stabilize mass production as soon as possible, they have the opportunity to become one of the mainstream suppliers of automotive laser radar.
