  • Patent number: 11242087
    Abstract: A synchronization signal generating portion of a transmitter microcomputer generates a synchronization signal that is synchronized with a drive timing of the own microcomputer and also causes to synchronize the drive timing of microcomputers, and transmits to a receiver microcomputer. A timing corrector of the receiver microcomputer is capable of correcting the drive timing of the own microcomputer so as to synchronize with the received synchronization signal, and includes a timing determiner which determines whether the received synchronization signal is normal or abnormal. The receiver microcomputer permits the timing correction if the synchronization signal is determined to be normal in the timing determination, and prohibits timing correction and drives the motor asynchronously with the transmitter microcomputer if the synchronization signal is determined to be abnormal.

  • Patent number: 11187536
    Abstract: A method for simultaneous location and mapping (SLAM) includes receiving, by at least one processor, a set of sensor measurements from a movement sensor of a mobile robot and a set of images captured by a camera on the mobile robot as the mobile robot traverses an environment. The method includes, for each image of at least a subset of the set of images, extracting, by the at least one processor, a plurality of detected objects from the image. The method includes estimating, by the at least one processor, a trajectory of the mobile robot and a respective semantic label and position of each detected object within the environment using the sensor measurements and an expectation maximization (EM) algorithm.

  • Patent number: 11180147
    Abstract: When having determined that an operation of an accelerator operator is initiated at a first timing and the operation amount continues to increase until a second specific timing arrives to become constant at a second timing, vehicle control means which a vehicle control apparatus comprises executes driving force control in such a manner that a time-differential value of controlled driving force during a first period from the second timing to a first terminal timing matches with a time-differential value of controlled driving force at the second specific timing as well as executes braking force control in such a manner that a time-differential value of the controlled braking force during the first period becomes a value more than or equal to a sum of a time-differential value of the controlled braking force at the second specific timing and a time-differential value of operation driving force at the second specific timing.

  • Patent number: 11173896
    Abstract: Provided is a parking assistance device capable of reducing inconvenience felt by a driver experienced in automatic parking control during parking at a target vehicle speed corrected to a lower speed at a start of use of automatic parking control, for example. The parking assistance device controls a vehicle speed of the vehicle during parking to assist parking of the vehicle. The parking assistance device increases the vehicle speed of the vehicle during parking in accordance with a behavior during parking or from previous parking of the vehicle.

  • Patent number: 11164450
    Abstract: A method for improving traffic flow at an intersection includes determining spacing data for a plurality of vehicles within traffic lanes that enable the plurality of vehicles to proceed to an intersection from a common direction, determining whether traffic flow proximate to the intersection is hindered due to spacings between the plurality of vehicles, and sending a request to at least one vehicle of the plurality of vehicles to move forward to improve the traffic flow proximate to the intersection. The spacing data may be derived from spacing-related sensor data captured by one or more vehicles of the plurality of vehicles. A corresponding apparatus and computer program product for executing the above method are also disclosed herein.

  • Patent number: 11149671
    Abstract: A vehicle system includes an internal combustion engine including a fuel injection valve configured to inject fuel into an intake port and a throttle valve configured to control intake air amount for controlling engine torque, and being mounted on a vehicle. The vehicle system further includes a control device configured to control the vehicle. The control device includes a fuel increment controlling component that executes a fuel increment control to make the air-fuel ratio richer than the stoichiometric air-fuel ratio in a plurality of cycles started from a fuel injection start cycle at the time of engine start-up. Where a torque rate correlation value correlated with a torque rate that is a time rate of increase of the engine torque is lower, the fuel increment controlling component decreases a total fuel injection amount in the plurality of cycles.
