Abstract: There is provided a method of controlling an electric vehicle. The method includes obtaining by a controller of the electric vehicle a first state indicator of a state of the electric vehicle, receiving at the controller a status indicator of an operating status of the electric vehicle, and updating by the controller the state of the electric vehicle based on the status indicator to an updated state. The updated state may be associated with a second state indicator. The method also includes determining by the controller a given braking type of a braking to be applied to the electric vehicle. This determining may be based on one or more of the second state indicator and the status indicator. The method also includes applying to the electric vehicle the braking of the given braking type. Systems for applying such braking are also provided.

The rotor has a hub portion, a cylindrical portion, and a disk portion. The hub portion of the rotor has a first end, a second end, and a through-hole therethrough. The brake assembly is fixed relative to the housing and configured to selectively couple the disk portion of the rotor to the housing. The first bearing is mounted between the first end of the hub portion of the rotor and the disk portion of the rotor. The second bearing is mounted between the second end of the hub portion of the rotor and the disk portion of the rotor.

Abstract: In an application, which refers to holding actuation of a parking brake mechanism (a rotation-linear motion conversion mechanism), a braking control apparatus (a parking brake control apparatus) determines an application stroke from a load detection point including as far as an overshoot amount. The load detection point is a generation point of a thrust force that is detected due to a current flowing in the electric motor. The overshoot amount is generated based on a rotation of an electric motor due to inertia after driving of the electric motor is stopped. The braking control apparatus determines a target release stroke in a release, which is release actuation of the parking brake mechanism, according to the application stroke. The braking control apparatus outputs a control instruction to conduct the release based on the target release stroke.

Abstract: A regenerative braking control system for a motor-driven vehicle is configured to provide a continuous assistant braking force by continuous reverse torque of an electric motor by enabling surplus electrical energy produced by an electric motor to be easily converted into thermal energy in generative braking, using both of a brake resistor and a heater to convert electrical energy into thermal energy, and being able to obtain an interior heating effect by using thermal energy converted by the brake resistor and the heater as heat source for interior heating without discharging the thermal energy to the outside.

Abstract: An electrical machine has a braking element and a release device. A rotor of the electrical machine includes the braking element and release device. The electrical machine is located, for example, in a rail vehicle. In order to brake the rotor of the electrical machine in the event of an error in the drive train, an overload torque is generated by the electrical machine. An overload clutch is triggered by the overload torque.

Abstract: An automated aerial vehicle (AAV) and system for automatically detecting a contact or an imminent contact between a propeller of the AAV and an object (e.g., human, pet, or other animal) are described. A safety profile for the AAV may be selected based on various factors including a position or configuration of the AAV. When a contact or an imminent contact is detected, the selected safety profile may be executed to reduce or avoid any potential harm to the object and/or the AAV. For example, if a contact with a propeller of the AAV by an object is detected, the rotation of the propeller may be stopped to avoid harming the object. Likewise, an object detection component may be used to detect an object that is nearing a propeller, stop the rotation of the propeller, and/or navigate the AAV away from the detected object.

Abstract: A linear actuator (1) comprises a spindle nut arranged to be moved between two end positions on a spindle driven by a DC motor (2). An end stop switch (31) is arranged to be activated when the spindle nut is in an end position. In its activated state, the end stop switch disconnects the motor current and connects a first diode (33) across the DC motor for short circuiting the motor when the current is interrupted. A second diode (32) is connected over the end stop switch for enabling the DC motor to drive the spindle nut out of said end position. An additional component (43) in series with the first diode reduces noise problems caused by motor current circulating through this diode during pulse pauses while the spindle nut is driven out of an end position by a pulse width modulated voltage via a cable from a control box.
