The present application relates to an electric off-road vehicle charging control method, a computer device and a storage medium. The method includes: acquiring first power-condition data and second power-condition data; the first power-condition data is a cumulative number of times a feedback ratio of a vehicle-mounted energy storage system is greater than a feedback ratio threshold; the second power-condition data is a cumulative number of times the feedback ratio is less than the feedback ratio threshold; comparing a target difference with a second preset threshold, and determining a charging mode according to the comparison result; the charging mode includes a normal charging mode and a reserving margin capacity charging mode; and controlling, if the charging mode is the reserving margin capacity charging mode, the vehicle-mounted energy storage system to stop charging in a case where the state-of-charge of the vehicle-mounted energy storage system reaches a full charge control state-of-charge.

A system for managing storage of electrical energy can include an electromagnetic machine and a controller. The electromagnetic machine can have a rotor and a stator. The rotor can be configured to be connected to a shaft. One of the rotor or the stator can have first windings and second windings. The controller can be configured to control first circuitry and second circuitry. The first circuitry can be configured to cause energy to flow from a first energy storage device to the first windings to cause the shaft to rotate. The second circuitry can be configured to cause energy to flow selectively: (1) from a second energy storage device to the second windings to cause the shaft to rotate or (2) from the second windings to the second energy storage device to cause the second energy storage device to be charged.

In the solution put forth, a pressure level of a pump in a hydraulic transmission system of a hydraulic working machine, or power that is feedable to an electric drive motor of an electric working machine is monitored, and/or the rotation speed at the output of the drive motor of the working machine and the rotation of moving means of the working machine are monitored. The pressure level of the hydraulic power transmission pump, or the power feedable to an electric drive motor, is compared with a lower threshold value to detect a fault situation, and/or the rotation speed at the output of the drive motor is compared with the rotation of the moving means also to detect a fault situation. In case a fault situation is detected, the braking system of the working machine is controlled to apply the brakes.

An embodiment driving distribution apparatus of a drone unit includes a first drone unit located on a first end of a vehicle and a second drone unit located on a second end of the vehicle, wherein each of the first and second drone units includes a sensor unit configured to measure a gradient traveling environment of the vehicle, a driving unit configured to apply a driving force of the vehicle, and a control unit configured to control driving amounts of the first drone unit and the second drone unit based on the gradient traveling environment of the vehicle.

A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.

A first power source system includes a first motor control section that controls at least torque of a drive motor. When a temperature of an FC is less than or equal to a prescribed temperature Th and a demand for high output is made to the drive motor, the first motor control section limits the torque of the drive motor to be lower than a maximum torque that can be output by the drive motor, and continuously implements this torque limitation.

A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.

Systems and methods for facilitating an operation of an electric off-road vehicle are provided. A method includes determining an estimated battery consumption data for a planned trip along a route including an off-road trail with the electric off-road vehicle using past battery consumption data and communicating the estimated battery consumption data for the planned trip to an operator of the electric off-road vehicle. When the electric off-road vehicle is travelling along the off-road trail, the method includes receiving actual battery consumption data associated with the electric off-road vehicle, and revising the estimated battery consumption data for the planned trip based on the actual battery consumption data. The revised estimated battery consumption data is communicated to the operator of the electric off-road vehicle during the planned trip.

A mobile object control device controls an electric motor assisting traveling of a mobile object. The mobile object control device includes a rolling resistance calculation section, a power loss calculation section, and an assist force calculation section. The rolling resistance calculation section calculates a rolling resistance based on a set weight set by a user. The power loss calculation section calculates a power loss caused until a power outputted from the electric motor is transmitted to a drive wheel. The assist force calculation section calculates an assist force of the electric motor based on an acceleration of the mobile object, the set weight, the rolling resistance calculated by the rolling resistance calculation section, the power loss calculated by the power loss calculation section, and an assist ratio.

Systems and methods for coordinating and providing towing acceleration assistance between towing vehicles and towed vehicles during vehicle towing events are disclosed. The towing acceleration assistance may be provided by the towed vehicle in the form of an assistive propulsive torque to assist the towing vehicle with acceleration during the towing event when one or more vehicle conditions indicate a need for the towing acceleration assistance. The towing acceleration assistance may end when the one or more vehicle conditions no longer indicate the need for the towing acceleration assistance.
