  • Publication number: 20210006183
    Abstract: Prior to starting of first and second synchronous motors, direct-current excitation is performed to pull in rotors of the synchronous motors to a designated position. In the direct-current excitation, a difference between a value of a direct current flowing through the first synchronous motor and a value of a direct current flowing through the second synchronous motor is reduced. For example, d-axis currents and q-axis currents corresponding to three-phase currents flowing through the motors are determined; a d-axis voltage command value for making one of the d-axis currents larger in absolute value equal to a d-axis current command value is determined, and a q-axis voltage command value for making one of the q-axis currents larger in absolute value equal to a q-axis current command value is determined; an inverter is driven using the determined d-axis voltage command value and q-axis voltage command value.

  • Publication number: 20200247373
    Abstract: A system for controlling a trailer brake output circuit includes an electronic control unit having one or more processors and one or more memory modules. The trailer brake output circuit is configured to output a trailer brake output signal. Machine readable instructions cause the electronic control unit to: receive a signal from a vehicle stability control system indicating that a vehicle stability control flag is set, generate the trailer brake output signal in response to the vehicle stability control flag being set such that the trailer brake output signal ramps up to a target value over a predefined period of time, maintain the trailer brake output signal at the target value while the vehicle stability control flag is set, and output the trailer brake output signal such that the trailer brake output signal ramps down from the target value when the vehicle stability control flag changes from set to not set.

  • Publication number: 20200247372
    Abstract: A vehicle control system of a vehicle includes a trailer brake control electronic control unit (ECU), which in turn includes a trailer brake output circuit. The trailer brake control ECU is configured to receive an electronic parking brake (EPB) state flag and a vehicle acceleration message. The dynamic EPB state flag indicates one of an ON state and an OFF state of a dynamic EPB, and the vehicle acceleration message indicates an acceleration of the vehicle. The trailer brake control ECU outputs, via the trailer brake output circuit, a trailer brake signal based on the acceleration of the vehicle indicated by the received vehicle acceleration message in response to determining that the received dynamic EPB state flag indicates the ON state.

  • Patent number: 10460451
    Abstract: In an evaluation information provision system, subject's motion data is stored in association with attributes. When an attribute is assigned, the evaluation information provision system selects feature data from a plurality of the subject's motion data associated with the assigned attribute. The evaluation information provision system calculates a score for the assigned attribute, for the user's motion, using a statistical distance between the selected feature data and the user's motion data. The calculated score is displayed, for example, as a screen.
