  • Patent number: 11802773
    Abstract: A method for navigating and route planning based on a HD map and with reference to other electronic devices moving along a similar route includes setting a start location and an end location; planning at least one navigation route based on the start location and the end location; acquiring locations of own electronic device and of co-travelling external electronic devices based on the HD map; acquiring speeds of the external electronic devices and selecting those moving at low speed; identifying moving directions of the slow-speed target electronic devices; and re-planning and resetting the at least one navigation route when the moving directions of the target electronic devices intersected with a direction of the lane. An electronic device and a server applying the method are also disclosed.

  • Patent number: 11694544
    Abstract: A traffic safety control method is provided. The method includes determining whether there is an intersection in front of a vehicle. When there is the intersection in front of the vehicle, a driving direction of the vehicle at the intersection is predicted according to a plurality of lane positions of the vehicle that are continuously obtained. A message is transmitted once the predicted driving direction is determined to be conflicting with a traffic rule of the intersection.

  • Patent number: 11562648
    Abstract: A method for providing driving assistance based on a HD map includes acquiring information such as position of a vehicle and timing, and acquiring a speed of the vehicle based on the manner of driving, and acquiring distance an intersection in front of the vehicle and information from a HD map such as traffic light intersection ahead. Deciding such as whether the vehicle can pass through the intersection based on the speed of the vehicle, intersection distance, and the traffic light information and prompting and/or controlling the vehicle if it is determined that passage through is not possible. A vehicle-mounted apparatus applying the method is also disclosed.

  • Patent number: 11465625
    Abstract: A traffic safety control method is provided. The method includes obtaining first related information of a road when a vehicle is traveling on a road. Second related information is detected using a detecting device of the vehicle when the first related information indicates that there is the intersection in front of the vehicle on the road. The vehicle is controlled according to the first related information and the second related information.

  • Publication number: 20210300372
    Abstract: An driving assistant method is provided. The method includes identifying a type of a traffic line between a current lane in which a vehicle is located and an adjacent lane of the current lane. The type of the traffic line is used to determine whether or not the adjacent lane is an overtaking lane. An overtaking speed of the vehicle is calculated when the vehicle can overtake from the current lane to the adjacent lane. A prompt including the overtaking speed is issued once the overtaking speed is obtained.

  • Patent number: 9382862
    Abstract: An air-fuel parameter control system includes an injector, an air-fuel parameter sensor, a fuel film parameter calculation module, an air-fuel parameter prediction module and a fuel injection calibration module. The injector injects fuel into an intake manifold. The air-fuel parameter sensor detects a detected air-fuel parameter in an exhaust pipe. The fuel film parameter calculation module calculates a fuel film parameter relating to a fuel film accumulated the intake manifold based on the detected air-fuel parameter, an amount of the injected fuel and an amount of air flowing into the engine. The air-fuel parameter prediction module predicts a predicted air-fuel parameter based on the detected air-fuel parameter and the fuel film parameter. The fuel injection calibration module calibrates the amount of the injected fuel based on a difference between a reference air-fuel parameter and the predicted air-fuel parameter.
