Patent number: 11872893Abstract: A propulsion system for a device includes an electric motor configured to generate torque to propel the device. A position sensor is adapted to determine a rotor position of the electric motor. The system includes a controller having instructions recorded for determining the rotor position when a sensor fault condition is detected. The controller is adapted to selectively command injection of a voltage signal in a direct magnetic axis in a synchronous reference frame when a motor speed of the electric motor is below a predefined motor speed threshold and the sensor fault condition is detected. The rotor position is estimated based in part on a motor current response to the voltage signal. The voltage signal is defined by an alternating periodic shape having respective constant segments in each of a plurality of control periods, the respective constant segments being discontinuous between the control periods.Type: GrantFiled: April 13, 2022Date of Patent: January 16, 2024Assignees: GM Global Technology Operations LLC, Seoul Nathional UniversityInventors: Anno Yoo, Seung-Ki Sul, Hyung-June Cho

Patent number: 11872898Abstract: An abnormality diagnosis system performs an abnormality diagnosis of a plurality of motor systems that include a motor for moving a moving body. The abnormality diagnosis system identifies a comparison target system that is the motor system, among the motor systems, that is a comparison target in relation to a diagnosis target system that is the motor system to be a target of the abnormality diagnosis. The abnormality diagnosis system acquires a state-related value that is a value related to an operation state of the motor from each of the diagnosis target system and the comparison target system. The abnormality diagnosis system performs a comparison of the state-related value that is acquired from the diagnosis target system and the state-related value that is acquired from the comparison target system, and diagnoses a presence or absence of an abnormality in the diagnosis target system using a result of the comparison.Type: GrantFiled: August 17, 2022Date of Patent: January 16, 2024Assignee: DENSO CORPORATIONInventor: Shinsuke Kawadu

Patent number: 11872899Abstract: A traction battery system of an electrically operable motor vehicle is configured in the form of an underfloor battery and has at least one first battery module and one second battery module. The traction battery system includes a battery assistant module that is designed for operating the battery modules. The battery modules and the battery assistant module, which have an assistant module housing, are oriented in series in relation to one another in the direction of a body longitudinal axis of a motor vehicle body, and can be arranged between a first sill and a second sill of the body. The battery assistant module has a load-transmitting element for transmitting forces acting on side elements of the body, which load-transmitting element extends from the first sill to the second sill in the direction of a body transverse axis of the body.Type: GrantFiled: July 6, 2021Date of Patent: January 16, 2024Inventors: Philipp Kellner, Christopher Volkmer, Max Falk, Ilija Brandic

Patent number: 11872900Abstract: When a charging connector of an EVSE is connected to an inlet, a vehicle transmits charging information to a server. The server determines whether or not there is a predetermined function which is set to OFF among functions for external charging included in the vehicle. When there is a predetermined function which is set to OFF, the server transmits a recommendation notification to a smartphone. The smartphone transmits selection information in response to an operation of a user on the recommendation notification to the server. Based on the selection information, the server generates setting information about the predetermined function and transmits the setting information to the vehicle. The vehicle performs a setting for the predetermined function according to the setting information.Type: GrantFiled: March 2, 2021Date of Patent: January 16, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yoshiyuki Tsuchiya

Patent number: 11872901Abstract: Described herein are vehicle charging systems, each comprising a recharge vehicle and a work vehicle configured to form an electrical connection and charge the work vehicle battery from the recharge vehicle battery. In some examples, this charging is performed at 500 kW or more or even at 1,000 kW or more. Furthermore, the connection and/or charging can be performed while both vehicles are moving (e.g., the recharge vehicle moving in front of the work vehicle). The recharge vehicle comprises one or more DC-DC converters, configured to boost a first voltage (V1) of the recharge vehicle battery to a second voltage (V2) of the work vehicle battery. It should be noted that these voltages vary depending on the state of charge of these batteries. In some examples, each DC-DC converter utilizes a combination of immersion, conductive, and convective cooling for different components of the converter.Type: GrantFiled: September 15, 2023Date of Patent: January 16, 2024Assignee: DIMAAG-AI, Inc.Inventors: Ian Wright, Max Chapman, Sean McLean
