  • Patent number: 11951984
    Abstract: An open vehicle includes a vehicle upper portion, a traveling device, an external sensor, and an ECU. The vehicle upper portion has a riding surface that forms a bottom surface of the riding space and is configured for a plurality of users to ride on. The ECU is configured to control the traveling device to cause the open vehicle to automatically travel. The ECU is configured to execute: a specific person recognition process to use the external sensor to recognize a specific person existing in an outside space; and an automatic travel control process to control the traveling device such that, when the specific person exists within a predetermined distance range, the traveling device executes at least one of moving the open vehicle away from the specific person and increasing a vehicle speed as compared to when the specific person does not exist within the range.

  • Patent number: 11939011
    Abstract: A stand-up vehicle includes a vehicle upper portion, a handrail, one or more biometric information sensors, and one or more processors. The vehicle upper portion has a riding surface on which a user stands. The handrail is provided at an upper portion of the vehicle and is gripped by a user. The one or more biometric information sensors are at least one of a sensor provided on a handrail and a weight sensor provided below a riding surface and having the riding surface as a weight detection surface, and detect biometric information of the user. The one or more processors perform notification processing for notifying a user of biometric information detected by the one or more biometric information sensors.

  • Patent number: 11938936
    Abstract: In a stand-up vehicle having a vehicle upper part having a riding surface configured for a user to stand on, one or more electronic control units execute emergency situation detection processing for detecting an emergency of the user when receiving notification from the user or based on information from one or more sensors, safety posture determination processing for determining whether or not the user takes a safety posture based on information from one or more sensors after detecting the emergency, and upper limit speed management processing executed when detecting the emergency and determining that the user takes the safety posture. The upper limit speed management process increases the upper limit speed to be higher than the basic upper limit speed selected when the safety posture determination process determines that the user is not in the safety posture, or cancels the upper limit speed.

  • Patent number: 11927958
    Abstract: An automatic traveling vehicle includes a vehicle structure including a first top plate, and an electronic control unit. The electronic control unit is configured to execute a storage mode when a storage execution condition is satisfied. The storage mode includes a storage posture formation process of causing the vehicle to automatically travel so as to take a predetermined storage posture together with a counterpart automatic traveling vehicle. In the storage posture, the vehicle is in a superposition state in which the vehicle overlaps with the counterpart vehicle in a plan view, or a parallel state in which the vehicle is lined up with the counterpart vehicle while the first top plate and a second top plate of the counterpart vehicle are standing and facing each other so as to be parallel to or substantially parallel to a vertical direction.

  • Publication number: 20230029300
    Abstract: A maintenance apparatus (10) transmits a pulse signal from a predetermined observation point (P) of rails (R), observes an observation signal that appears at the observation point (P) after transmission of the pulse signal, compares an observation history of the observation signals and the observation signal received this time, and detects occurrence of abnormality in any one of the rails (R) and at least one electric apparatus (20) connected to the rails (R).

  • Publication number: 20210376390
    Abstract: An object of the present disclosure is to provide a nonaqueous electrolyte secondary battery resistant to the occurrence of electrode plate deformation which can cause an internal short circuit. A nonaqueous electrolyte secondary battery according to an example embodiment of the present disclosure includes a wound electrode assembly including a positive electrode, a negative electrode and a separator, and a nonaqueous electrolyte. The separator is bonded to the positive electrode over a region from the end of the positive electrode on the coiling start side to a length corresponding to at least one loop in the winding direction.

  • Publication number: 20190386344
    Abstract: A nonaqueous electrolyte secondary battery is disclosed including a flat electrode body in which an electrode group including a positive electrode plate, a negative electrode plate, and a separator interposed therebetween is rolled, a nonaqueous electrolyte, and an outer jacket member. The electrode body includes bent portions, in which an electrode group is bent, at both end portions in the major axis direction of a cross section perpendicular to a rolling axis. A resin tape is attached to a portion, which is arranged nearest the rolling start position of the positive electrode plate, of the roll inner surface of the positive electrode mix layer in the bent portion. The resin tape includes an adhesive layer and a base material layer that does not pass lithium ions. An adhesive force of the resin tape to the positive electrode mix layer is 0.1 N/cm or more and 2 N/cm or less.
