2results about How to "Traffic safety" patented technology

A multi-functional transport trolley for inclined shaft widening includes a vehicle frame, a traveling mechanism, a transport platform, an unloading channel, and a pedestrian ladder. The top of the inclined surface of the vehicle frame is equipped with lifting lugs. The transport platform is fixed to the top of the vehicle frame and includes a platform steel plate, guardrails, and a detachable partition fence. The platform steel plate is fixedly connected to the top of the vehicle frame around its perimeter, and the guardrails are installed around the transport platform. The detachable partition fence is telescopic and is fixed to the guardrails with snap-fit ​​fasteners. The platform steel plate has an unloading hole and a manhole, both with covers. An unloading channel is provided on the inclined surface of the vehicle frame below the unloading hole, and a pedestrian ladder is provided on the inclined surface of the vehicle frame below the manhole. The traveling mechanism is symmetrically installed on both sides of the inclined surface of the vehicle frame. This transport trolley uses detachable partition fences to freely divide the transport platform, enabling simultaneous transport of personnel and materials, improving transport efficiency and ensuring personnel safety.

The present disclosure relates to a vehicle control method, a program product and a vehicle. The vehicle control method is applied to a first vehicle and includes: in a case where the first vehicle is to change lanes to a target lane, determining a perceived second vehicle; generating N pieces of candidate trajectory information of the first vehicle; generating predicted trajectory information corresponding to M predicted driving conditions of the second vehicle, the M predicted driving conditions including predicted driving conditions with different occurrence probabilities; determining a target generation value of each trajectory combination in a plurality of trajectory combinations; and controlling the first vehicle to travel according to candidate trajectory information in a trajectory combination corresponding to a minimum target generation value. By the above scheme, the predicted driving conditions of the second vehicle with different occurrence probabilities are considered, the frequent jumping phenomenon of the first vehicle driving trajectory decision is reduced, the collision risk is reduced, and the safety and efficient passing of the first vehicle in the lane changing process are ensured.
