  • Patent number: 11085392
    Abstract: An intake air amount measuring device includes a by-pass-type air flowmeter and a processor that calculates an intake air amount of an engine based on the measurement result of the air flowmeter. When calculating the intake air amount, the processor performs lag or lead compensation for a response delay of a change in an intake flow rate in the bypass passage in relation to a change in an intake flow rate in the main passage based on loss coefficients of the main passage and the bypass passage. The processor causes values of the loss coefficients of the main passage and the bypass passage, which are used in the compensation, to be different between a forward flow state, in which the intake air flows through the main passage in a forward direction, and a backflow state, in which the intake air flows through the main passage in a reverse direction.

    Abstract: A target detection device mounted in a vehicle includes: a radar specification unit; a same target determination unit; and an image specification unit that specifies, as image target position information, an image detection region of an image detection target detected on the basis of a captured image, the image detection region representing the position of the image detection target relative to the base point on an XY-plane with the X-axis representing the vehicle width direction of the vehicle and the Y-axis representing the vehicle length direction of the vehicle. The image specification unit sets the Y-axis range of the image detection region in the Y-axis direction on the basis of the bearing from the base point to each of the two X-directional ends of the image detection target in the captured image and of an expected width minimum value and an expected width maximum value in the X-axis direction.

  • Patent number: 11087623
    Abstract: Systems and methods for compensating for driver speed-tracking error are disclosed herein. One embodiment computes a recommended speed for a vehicle; classifies a driver of the vehicle as a particular type of driver among a plurality of driver types based on measured speed-tracking error, wherein the speed-tracking error is a difference between the recommended speed and an actual speed of the vehicle; predicts the speed-tracking error at a future time increment based on the speed-tracking error at one or more past time increments using a nonlinear autoregressive (NAR) neural network associated with the particular type of driver; computes a compensated recommended speed for the vehicle based on the recommended speed and the predicted speed-tracking error at the future time increment; and communicates the compensated recommended speed to the driver.

  • Patent number: 11087568
    Abstract: Systems and methods are provided for monitoring time-series data relative to a temporal logic specification regarding expected behavior of a system, such as a vehicle. The time-series data and a threshold value(s) specified in the temporal logic specification may be encrypted and analyzed without decrypting the time-series data to maintain the privacy of a user(s) of the vehicle. Encryption of the time-series data and the threshold value(s) may be accomplished using an order preserving encryption scheme. Analysis of the time-series data may be accomplished utilizing a batch processing-type architecture or a continuous processing-type architecture. When utilizing the continuous processing-type architecture, historical time-series data may be stored and utilized to determine whether currently-monitored time-series data satisfies the temporal logic specification.

  • Publication number: 20210237584
    Abstract: When regeneration control is performed while yaw rate control is being performed, the regeneration control is prohibited, or a regenerative torque of a second rotary machine based on the regeneration control is limited in comparison with a case in which the yaw rate control is not performed. Accordingly, since an influence of the regenerative torque controlled by the regeneration control on the yaw rate control can be suitably curbed, it is possible to curb deterioration in conformability of an actual yaw rate with a target yaw rate in the yaw rate control.
