Huawei Technologies Co., Ltd.’s patent “a driving safety measurement system for autonomous vehicles” has recently been authorized, and the applicants also include Beihang University.
The patent abstract shows that the present invention discloses a driving safety quantification system for autonomous driving vehicles, including a driving area environmental risk quantification module, a surrounding traffic participant conflict interference quantification module, a self-vehicle behavior risk quantification module, a vehicle driving safety quantification module, The display module, in which the output of the driving area environmental risk quantification module, the surrounding traffic participant conflict interference quantification module and the self-vehicle behavior risk quantification module is finally synthesized into the vehicle driving safety quantification module and the real-time safety value of vehicle driving is calculated, using different colors The difference is displayed on the display module, prompting the driver the safety status of the automatic driving system. Patent diagram is as follows:
The system quantifies the environmental complexity, the interference of surrounding traffic participants, and its own behavior status factors that affect the safety of human drivers while driving, and can provide different degrees of safety warnings and constraints for the autonomous vehicle system and its human drivers. The vehicle keeps it in a relatively stable driving state.
In terms of actual intelligent driving, Huawei chose the automatic driving technology route of multi-sensor fusion and coordination. In April this year, Huawei’s high-end intelligent driving system ADS 2.0 was released. It will not rely on high-precision maps to achieve high-level assisted driving. The M5 high-end intelligent driving version is equipped with Huawei ADS 2.0 for the first time.
