Patent number: 11959328Abstract: A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body including an adjustment member, a drive element operatively coupled to the adjustment member such that the adjustment member is movable with respect to the drive element for moving the vehicle door, a sensor device for measuring a measuring quantity indicative of a movement of the vehicle door to provide a sensor signal, a brake device operatively connected to the drive element for braking a movement of the vehicle door, and a control device for controlling operation of the door drive device. The control device is configured to compute, from the sensor signal obtained from the sensor device, an acceleration value indicative of an acceleration of the vehicle door and evaluate the acceleration value to distinguish movement of the vehicle door caused by a gravity force from movement caused by a user action.Type: GrantFiled: February 14, 2019Date of Patent: April 16, 2024Assignee: Brose Fahrzeugteile SE & Co. Kommanditgesellschaft, BambergInventors: Takafumi Eguchi, Sebastian Vogt, Daniel Steiner

Publication number: 20240112509Abstract: A vehicle is a vehicle that is equipped with an illumination device in a vehicle cabin and that is capable of traveling in an EV mode, the vehicle being configured to change a manner of luminescence of the illumination device when the vehicle enters a low emission zone (LEZ) where the vehicle needs to travel in the EV mode, and to cause a driver to perceive the entrance. For the change in the manner of the luminescence, for example, the color of the luminescence of the illumination device may be changed from a regular color to a specific color. By the change in the manner of the luminescence of the illumination device, it is possible to cause the driver to sensorily recognize the entrance to the low emission zone.Type: ApplicationFiled: September 29, 2023Publication date: April 4, 2024Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, SUMITOMO WIRING SYSTEMS, LTD.Inventors: Yasunori WAKAMATSU, Masatoshi ISHINO, Yuuki ARAI, Takafumi EGUCHI, Akihiro KUSADA

Publication number: 20220332315Abstract: A method for operating a motor vehicle, in which an object situated in a sensor region is detected with the aid of a sensor in surroundings of the motor vehicle; A piece of position information relating to the object is created. The position information is retained when the object is moved out of the sensor region, due to a movement of the motor vehicle, the distance of the object to the motor vehicle not increasing. The invention further relates to a motor vehicle and a computer program product.Type: ApplicationFiled: April 18, 2022Publication date: October 20, 2022Applicant: Brose Fahrzeugteile SE & Co.

Patent number: 11408220Abstract: A control unit for establishing a functional connection between two gearing components comprises at least one control element, which can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow movement of the gearing components in relation to one another in a second switching state. An actuator is used to move the at least one control element. A control mechanism controls the actuator. It is provided thereby that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state, in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).Type: GrantFiled: December 14, 2018Date of Patent: August 9, 2022Assignee: BROSE FAHRZEUGTEILE GMBH & CO. KOMMANDITGESELLSCHAFT, BAMBERGInventor: Takafumi Eguchi

Publication number: 20220098916Abstract: A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body includes an adjustment member and a drive element operatively coupled to the adjustment member. A sensor is configured to measure movement of the vehicle door and/or a force acting onto the vehicle door and to output a sensor signal. A control device is configured to control operation of the door drive device and is programmed to detect an action onto the vehicle door indicative of a user command for moving the vehicle door based on the sensor signal, and conclude for an action onto the vehicle door indicative of a user command for moving the vehicle door by evaluating a characteristic value derived from the sensor signal based on a decision parameter, wherein the decision parameter is variable depending on a movement direction of the vehicle door.Type: ApplicationFiled: February 1, 2019Publication date: March 31, 2022Applicant: Brose Fahrzeugteile SE & Co.
