  • Patent number: 11447144
    Abstract: Embodiments of the present disclosure relate to methods for updating an autonomous driving system, autonomous driving systems, and on-board apparatuses. In the embodiments of the present disclosure, the autonomous driving system, in a manual driving mode, senses the surrounding environment of a vehicle, performs vehicle positioning, and generates an autonomous control instruction for an underlying vehicle execution system. However, the autonomous driving system does not issue an instruction to control the driving of the vehicle. Instead, it compares the instruction with a control instruction from the driver of the vehicle for the underlying vehicle execution system in the manual driving mode to update a planning and control algorithm of the autonomous driving system. As such, the updated autonomous driving system better caters to the driving habits of the driver and improves the driving experience for the driver without compromising the reliability of planning and decision-making of autonomous driving.
