Assuming that a car factory needs to modify the function of a wiper assembly, since each car has to define, calibrate and verify the wiper assembly at a given point in the development process, the subsequent modification is equivalent to secondary development, car companies need Re-sign the contract with the wiper supplier, and re-do the calibration and verification of each level. Obviously, such a hardware-oriented engineering system and process cannot support the rapid iterative evolution of products in the future when vehicles become more and more complex.
The solution is to standardize the hardware. The wiper assembly is a mechanical component driven by a motor. The sensors required by the wiper can call the camera or other sensors on the vehicle. Once the transparency of the windshield is sensed, the vehicle can automatically activate the appropriate working mode for the wiper through software control. , which realizes the purpose of software-defined wiper function. When various assemblies and modules are standardized, higher-level intelligence can be realized through the software in the central controller, just like multiple APPs running on a mobile phone, which can greatly shorten the product development cycle The widespread adoption of standardized components helps companies control costs and quality.
