An electrically driven vehicle contains a current collector for supplying electrical energy from a bipolar overhead line system. The collector has an articulated support rod, which bears, on the contact wire side, a contact collector having a contact strip, and which is coupled, on the vehicle side, to a lift drive for positioning the support rod and for pressing the contact collector to a contact wire of the overhead wire system, a detection device for detecting a lateral position of a contact point of the contact wire on the contact strip and a driver assistance system for executing an automatic steering intervention as a function of the detected lateral position of the contact point. The vehicle has increased availability for a feed of electrical energy from the overhead line system in that the contact strip is supported on the contact collector via at least two spring elements.

A mobile vehicle wirelessly receives AC power from a power transmission device including first and second power transmission electrodes arranged along a road surface. The mobile vehicle includes: a sensor that detects an obstacle located at least either on a route of the mobile vehicle or under the mobile vehicle; a first power reception electrode that forms electric field coupling with the first power transmission electrode when facing the first power transmission electrode; a second power reception electrode that forms electric field coupling with the second power transmission electrode when facing the second power transmission electrode; an actuator that moves at least the part of the first power reception electrode in a direction of gravity; and a control circuit that controls the actuator based on a result of detection by the sensor to avoid contact between the first power reception electrode and the obstacle.

A method of controlling vibration reduction of a vehicle is capable of efficiently reducing vibration occurring when entering a P range on a ramp. The method includes: when an input to a parking range is received, determining whether or not a predetermined condition for entering a vibration reduction control mode is satisfied; when the entering condition is satisfied, calculating a motor torque for reducing vibration due to backlash by using the driving information; controlling a driving motor so as to output the calculated motor torque; controlling the parking device such that the parking range is engaged; determining whether or not a brake is released; and if the brake is released, reducing a motor torque output by the driving motor so that vibration due to the backlash is reduced.

An autonomous mobile device (AMD) operating in a first mode moves within a physical space to perform various tasks such as displaying information on a screen, following a user, and so forth. The first mode may involve the AMD moving or maintaining a particular pose. While the AMD is in the first mode, a user may apply an external force to the AMD to reposition the AMD to a desired pose. Application of this external force on the AMD is detected and results in the AMD transitioning to a second mode in which the AMD may be repositioned. While in the second mode, the user may reposition the AMD. The second mode may constrain the magnitude of the resulting movement, preventing the user from moving the AMD too quickly which could damage components within the AMD. Once the external force ceases, the AMD may transition back to the first mode.

Environmentally friendly electrical vehicles are presented. The electrical vehicles include electrical low speed vehicles (LSVs) that may use sensed location data to obtain one or more operational profiles. The operational profiles may govern the behavior of the LSV in a specific environment, area, or zone to ensure the LSV reduces its impact on the local terrain. The LSV may leverage locally sensed data to form a local context in which the LSV is operating. The LSV's vehicular controller may refine the operational parameters of the operational profile to ensure smooth operation based on local conditions from the local context.

A method uses the electric motor (4) of an electric vehicle to reduce vibration of the vehicle body (1). The electric motor (4) is supported on the vehicle body (1) or on the subframe (2) of the electric vehicle. The method includes determining a vibration of a subframe (2) or of the vehicle body (1) in the area of force introduction sites where electric motor (4) is supported. The method proceeds by determining a torque required to be generated by the electric motor (4) to introduce a force into the subframe (2) or into the body (1) for counteracting the force caused by the determined oscillation acting on the subframe (2) or the vehicle body (1) and adjusting at least one driving signal of the electric motor (4) such that the required torque is generated based on the change in the drive torque of the electric motor (4).

A power management system for an air mobility vehicle includes a plurality of batteries configured to provide power to a propulsion unit of the air mobility vehicle to propel the air mobility vehicle, and a discharge control unit configured to monitor an operation state and a charge state of each battery, determine a discharge mode of each of the plurality of batteries according to the monitored operation state and the monitored charge state, and control whether each of the plurality of batteries is discharged or a discharge rate thereof according to the determined discharge mode.

Aspects of the disclosure relate generally to speed control in an autonomous vehicle. For example, an autonomous vehicle may include a user interface which allows the driver to input speed preferences. These preferences may include the maximum speed above the speed limit the user would like the autonomous vehicle to drive when other vehicles are present and driving above or below certain speeds. The other vehicles may be in adjacent or the same lane the vehicle, and need not be in front of the vehicle.

A method for controlling regenerative braking includes setting a filter simulation map for simulating a filter of removing or passing a natural frequency component of vehicle suspension pitch motion according to suspension device characteristics of the vehicle and providing the filter simulation map to a controller of the vehicle, determining, by the controller, a required regenerative braking force command based on vehicle driving information collected during driving of the vehicle, determining a final front wheel regenerative braking force command and a final rear wheel regenerative braking force command from the determined required regenerative braking force command through a limit value application process using a limit value determined in the filter simulation map, and controlling a regenerative braking force applied to front and rear wheels as a force for decelerating the vehicle by a driving device for driving the vehicle according to the determined final front and rear wheel regenerative braking force commands.

Systems and methods are directed to dynamically and automatically adjusting a standard regenerative braking intensity. Roadway data, data from one or more sensors of a vehicle and data including parameter values for operating states of the vehicle regarding a roadway from a route being navigated by the vehicle are received by a processor of a control system of the vehicle. Standard regenerative braking intensity values based on a vehicle's acceleration is retrieved from memory. Adjusted regenerative braking intensity values are calculated based on at least one of the roadway data, the sensor data and the parameter values of the operating states of the vehicle and the standard regenerative braking intensity values. The adjusted regenerative braking intensity values are transmitted to the control system and an acceleration or deacceleration amount is applied to the vehicle based on the adjusted regenerative braking intensity values.
