  • Patent number: 11535237
    Abstract: An electric device control method controls an electric device that includes an internal combustion engine, a first electric motor that receives a driving force of the internal combustion engine to carry out power generation, and a second electric motor connected to a drive shaft. The method sets a rotational speed of the internal combustion engine to increase as a vehicle speed of the vehicle increases while the power generation is carried out by the first electric motor. Where the driving force required by the second electric motor becomes zero or negative while the first electric motor is carrying out power generation by the driving force of the internal combustion engine, the internal combustion engine is stopped where the vehicle speed is greater than or equal to a first threshold value, and the power generation is continued where the vehicle speed is less than the first threshold value.

  • Patent number: 11531353
    Abstract: Examples relating to vehicle velocity calculation using radar technology are described. An example method performed by a computing system may involve, while a vehicle is moving on a road, receiving, from two or more radar sensors mounted at different locations on the vehicle, radar data representative of an environment of the vehicle. The method may involve, based on the data, detecting at least one scatterer in the environment. The method may involve making a determination of a likelihood that the at least one scatterer is stationary with respect to the vehicle. The method may involve, based on the determination being that the likelihood is at least equal to a predefined confidence threshold, calculating a velocity of the vehicle based on the data from the sensors. The calculated velocity may include an angular and linear velocity. Further, the method may involve controlling the vehicle based on the calculated velocity.
