A guardrail estimation method based on multi-sensor data fusion is provided. The guardrail estimation method comprises acquiring multi-sensor data and vehicle information, determining a traveling track of the vehicle based on the vehicle information, determining multiple guardrail sample points based on the multi-sensor data and the traveling track, and estimating guardrail information based on the multiple guardrail sample points. When the vehicle is controlled laterally, the guardrail information is used for correcting a lane line of poor quality; and when the lane line cannot be detected, the guardrail information is used for a lateral control downgrade processing, and the guardrail information also facilitates aided realization of fast and accurate expressway lane-level localization and realization of a higher-level aided driving function.

Guardrail estimation method based on multi-sensor data fusion, and vehicle-mounted device

A method and a device for determining traffic stream information, electronic equipment and a storage medium are provided. The method includes: grouping each of target vehicles based on motion information of a host vehicle and state information of one or more of the target vehicles to obtain grouping information; determining a fitting weight for each of the target vehicles based on the state information and the grouping information for each of the target vehicles; and generating, by the fitting, one or more pieces of current traffic stream information based on the motion information of the host vehicle, the state information of each of the target vehicles, the fitting weights and the grouping information of each of the target vehicles. The method can generate the current traffic stream information to achieve the sensing of traffic stream.

Method and device for determining traffic stream information, electronic equipment and storage medium

A method and a device for sensing a traffic congestion, electronic equipment and a storage medium are provided. The method for sensing the traffic congestion includes: acquiring driving environment information including lane line information of a lane in which a host vehicle is located, host vehicle driving information, and vehicle information of surrounding vehicles; determining a driving path of the host vehicle based on the lane line information and the host vehicle driving information; determining an effective vehicle on at least one side of the host vehicle from the surrounding vehicles based on the host vehicle driving path and the vehicle information of the surrounding vehicles; and determining a current congestion state of a corresponding lane based on vehicle information of the effective vehicle on at least one side of the host vehicle and a historical congestion state of the corresponding lane.

Traffic congestion sensing method and apparatus, electronic device and storage medium

The disclosure relates to a portable device for unlocking a vehicle, a method, and a storage medium. The portable device includes a communication unit and a processing unit. The communication unit is configured to scan a pairing request signal from the vehicle, and transmit a locking/unlocking signal to the vehicle. The processing unit is configured to: receive a motion status signal indicating a motion status of the portable device and a temperature signal indicating an ambient temperature of the portable device; and switch an operating mode of the portable device based on at least one of the motion status signal and the temperature signal. The portable device for unlocking a vehicle proposed in the disclosure can switch its operating mode in response to a change in the motion status and the ambient temperature, thereby solving a problem of fast power consumption and a short service life of a smart key, and solving a problem of failure of a function of the smart key at high temperature in summer or at low temperature in winter.

Portable device for unlocking vehicle, method, and storage medium

A vehicle positioning method and apparatus, an electronic device, and a storage medium are provided. The method comprises: determining a current positioning-established lane on the basis of current position information of a vehicle, road information sensed by the vehicle and map information; comparing the road information sensed by the vehicle acquired in real time with the current positioning-established lane to determine a mismatch integral value; and after determining that the mismatch integral value is greater than or equal to a preset integral value, returning to execute the step of determining the current positioning-established lane on the basis of the current position information of the vehicle, the road information sensed by the vehicle and map information.
