Method and device for taking over a vehicle in a drive-by-wire parking maneuver
The application relates to a vehicle takeover method and device for driving and parking, wherein the method comprises the following steps: detecting the current state of the vehicle, recommending to search for a parking space meeting preset parking conditions during driving; sending a release reminding signal of a throttle pedal and a steering wheel to a user based on an activation instruction; within a preset time length, generating a parking planning route of the vehicle according to the actual position of the parking space and the current position of the vehicle, and controlling a parking system to drive the vehicle to park into the parking space according to the parking planning route. According to the application, when it is detected that the driver releases the throttle pedal and the steering wheel, the parking planning route of the vehicle is generated according to the actual position of the parking space and the current position of the vehicle, and the parking system is controlled to drive the vehicle to park into the parking space according to the parking planning route, so that the parking efficiency is improved, the demand of the user for driving and parking is met, the use experience of the user is improved, and the intelligence and practicability of the vehicle are ensured.

Multi-stage parallel parking path planning method for heavy-duty all-wheel steering vehicle
ActiveCN116625370Bsolve space problemssolve efficiency problemsNavigational calculation instrumentsInternal combustion piston enginesVehicle dynamicsReliability engineering
This invention relates to a multi-segment parallel parking path planning method for heavy-duty all-wheel steering vehicles. Based on vehicle parameters and parallel parking space dimensions and road information detected by sensors, a parallel parking scenario for the all-wheel steering vehicle is established. The starting parking point information for vehicle positioning is input, and a designed algorithm is executed to detect existing safe parking paths in real time. Specifically, a series of parking paths are generated using a parameter sampling method and discretized. Road constraints and vehicle dynamics constraints that need to be satisfied during parking are defined. A path evaluation function is designed to evaluate and optimize paths that meet the constraints, thus completing the optimized design of parallel parking paths for multi-segment, multi-steering mode vehicles. This achieves more flexible parking path design for heavy-duty all-wheel steering vehicles, reduces parking space occupied during parking, and improves parking efficiency.

Parking lot navigation system based on infrared positioning and dynamic path optimization
PendingCN122290372AHigh positioning accuracyCounteract environmental interferenceMiddle infraredIn vehicle
This invention relates to the field of infrared positioning and parking lot navigation technology, specifically to a parking lot navigation system based on infrared positioning and dynamic path optimization, including an adaptive infrared positioning module and a dynamic path planning module. In the adaptive infrared positioning module, the infrared transmitting units are distributed in a mesh network and automatically adjust their power. The vehicle-mounted receiving unit calculates the initial coordinates using an improved RSSI model, and then corrects the initial coordinates using an error compensation formula that includes correction coefficients and vehicle speed. The dynamic path planning module divides the road into intelligent road segment units and calculates the congestion coefficient. It uses an ST-Attention-GNN model to predict parking space status and travel time, and outputs the planning results based on an A* algorithm with an improved evaluation function, thereby improving positioning accuracy and navigation efficiency.
