A system generates haptic feedback in an electric vehicle. The system comprises a frame, an energy storage device, and a wheel rotatably coupled to the frame. A motor receives power from the energy storage device and provides torque to the wheel. A controller determines a first operational state of the electric vehicle and transmits a first torque signal to the motor to control the motor to transmit first torque levels to the wheel to propel the electric vehicle. The controller determines a second operational state of the electric vehicle and transmits a second torque signal to the motor assembly. The motor assembly transmits second torque levels to the wheel to generate haptic feedback. The second torque signal is based on the second operational state of the electric vehicle and a torque profile stored in the memory, where the torque profile defines an irregular-shaped periodic waveform (e.g., a heartbeat rhythm).

A method (100) for operating a vehicle (1) with an electric drive-train (2), wherein this electric drivetrain (2) is fed via a DC voltage source (3) and a converter (4) for converting the DC voltage into a single-phase or multiphase AC voltage, comprising the steps: —it is detected (110) that the vehicle (1) is stopped; — it is checked (120) on the basis of at least one specified criterion (10) whether the vehicle (1) is expected to be stopped only briefly; —in response to the fact that the vehicle (1) is expected to be stopped only briefly, the vehicle (1) is transferred (130) from the ready-to-drive state into a disabled state, wherein in this disabled state the vehicle (1) is protected against unauthorized use but the converter (4) continues to be supplied with the DC voltage from the DC voltage source (3); —in response to the fact that the vehicle (1) is not expected to be stopped only briefly, at least one functional test of the electric drivetrain (2), said test being provided for powering down the electric drivetrain (2), is performed (140), and after the termination of this functional test the vehicle (1) is transferred (150) into a switched-off state, in which the vehicle (1) is secured against unauthorized use and the supply of the converter (4) from the DC voltage source (3) is interrupted.

Methods, systems, devices and apparatuses for a vehicle control system. The vehicle control system includes a memory. The memory is configured to store multiple charging events that activate multiple charging plans. The vehicle control system includes a navigation unit that is configured to obtain a current location of the vehicle. The vehicle control system includes an electronic control unit. The electronic control unit is configured to determine that the vehicle is within a threshold distance of the first charging event. The electronic control unit is configured to control an operation of the vehicle to prepare the vehicle to charge or discharge the battery based on a first charging plan when the vehicle is within the threshold distance of a first charging event.

A method for operating an electric drivetrain of a working machine is provided wherein the drivetrain comprises a work drive with an electric work motor and a travel drive with an electric travel motor and vehicle wheels, wherein the working machine experiences a speed deceleration from the outside that may result in a braking force acting on the vehicle wheels lower than a driving force acting on the vehicle wheels due to a moment of inertia of the travel motor. The method includes supplying the travel motor with a power in a direction opposite to an operating direction of the travel motor in order to reduce a rotational speed of the travel motor, if it is detected in advance using a situation detection that the braking force acting on the vehicle wheels as a result of the speed deceleration is lower than the driving force acting on the vehicle wheels.

A control device for controlling a vehicle provided with a power supply function for a user includes a control unit that causes a light of the vehicle to blink under a certain condition when a power outage is detected.

Systems and methods for coordinating steering controls between towing vehicles and towed vehicles provide more cohesive parking experiences during towing events, including bidirectional charging towing events. The towed vehicle may be controlled to provide assistive parking steering maneuvers to assist the towing vehicle when parking during the towing event. The assistive parking steering maneuver may include maneuvering a drive wheel of the towed vehicle either toward or away from a detected curb or detected traffic, for example.

A control device includes a control unit that acquires an image taken by a vehicle provided with a power supply function for a user, identifies an electric light that is turned off and that is included in the acquired image, refers to definition data that defines whether the identified electric light should be turned on during a time zone when the image was taken to determine whether a power outage has occurred.

An electric marine propulsion system is configured to propel a marine vessel and comprises a lithium ion (LI) battery, a marine drive having an electric motor powered by the LI battery, and a user input device configured to receive a user input selected an emergency depletion mode. The system further includes a controller configured to determine a battery charge level for the LI battery and reserve a minimum charge level of the LI battery associated with a normal operating area for the LI battery by ceasing power delivery from the LI battery to the marine drive once the battery charge level reaches the minimum charge level. In response to selection of the emergency depletion mode, power is delivered from the LI battery to the marine drive when the battery charge level is below the minimum charge level.

The power supply control device includes a processor configured to request noncontact power supply from the power supply apparatus to the vehicle; confirm an intention to utilize a noncontact power supply with an occupant of the vehicle, and stop the request for noncontact power supply if the occupant does not have the intention to utilize.

There are described herein methods and systems for operating an electric motor of a watercraft. In one method, the electric motor of the watercraft is controlled based on commands received from an accelerator of the watercraft, a sensor signal is received from at least one sensor of the watercraft while the electric motor is in operation, the sensor signal indicative of an undesirable condition of a water intake of the watercraft, and a change is effected to the controlling of the electric motor in response to receiving the sensor signal.
