It can improve the safety and efficiency of road traffic, reduce the occurrence of traffic accidents, alleviate traffic congestion, and bring more convenience and comfort to mobile travel. At the same time, autonomous driving technology has also brought new business opportunities and development space to automobile manufacturers, transportation companies and travel service providers, and passive driving robots are the most critical products of autonomous driving technology.

[0003] Passive driving robots refer to robotic systems with autonomous navigation and operation capabilities, which can complete tasks and actions without human intervention. The development of passive driving robots in the field of transportation is particularly noteworthy. The growing number of vehicles, the demand for traffic safety and efficiency, and the pursuit of driver comfort and convenience have all prompted the development of passive driving technology.

[0004] When a passive driving robot is manipulating a driving vehicle, it needs to be fixed to the car in order to drive more stably. In the prior art, the passive driving robot is fixed to the seat with a seat belt, which is easy to cut the seat belt, has poor stability, and is easy to cause dangerous accidents; and for different passive driving robots, it is difficult to fix the seat belt. Therefore, this application provides a car execution positioning device based on the driving state of the passive driving robot, which can adjust the position of the passive driving robot and the car seat slide rail and fix the position according to the position of the passive driving robot relative to the brake pedal, accelerator pedal, and steering wheel of different driving vehicles. It is suitable for different types of passive driving robots, so that the passive driving robot increases stability and safety during the driving process. Summary of the invention

After the passive driving robot gets on the vehicle, the positions of the first adjustment mechanism and the second adjustment mechanism can be adjusted to be precisely aligned with the seat slide rails, thereby compensating for the position error between the passive driving robot and the driving vehicle seat, increasing the tolerance of the passive driving robot's position, and reducing repeated position adjustments.

[0019] The adjustment mechanism of the present application can realize left-right adjustment and at the same time can adjust the length by telescoping to achieve fixation at different distances between the seat rail of the driving vehicle after installation.
