摘要： An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination. When operating autonomously the autonomous electronic bicycle can shift between a set of balance modes, including a mode used when moving and a mode used when stationary but balanced. To transition between modes, a transition sequence of control commands can be selected and used.

摘要： A vehicle includes a battery, an electric machine, and a controller. The battery has a state of charge. The electric machine is configured to draw electrical power from the battery to propel the vehicle in response to an acceleration request and to deliver electrical power to the battery to recharge the battery. The controller is programmed to adjust an estimation of battery state of charge based on a feed forward control that includes a coulomb counting algorithm, a first feedback control that includes a first battery model, and a second feedback control that includes a second battery model. The controller is further programmed to control the electrical power flow between the battery and the electric machine based on the estimation of the state of charge of the battery.

摘要： A brake force control apparatus allocates all of required brake force to a target front wheel friction brake force when the required brake force is equal to or smaller than a maximum regeneration brake force. The apparatus decreases the target regeneration brake force by a first predetermined amount at a first time point at which a front wheel acceleration varies from a value larger than a first acceleration threshold to a value equal to or smaller than the first acceleration threshold. The apparatus increases the target regeneration brake force in such a manner that the target regeneration brake force coincides with the required brake force, if the front wheel acceleration becomes larger than a second acceleration threshold in a period from the first time point to a second time point at which a predetermined time elapses from the first time point.

摘要： A system and method for adjusting an electric vehicle charging speed that include determining that an electric vehicle arrives at a charging station and receiving electric vehicle pricing data associated with a price to charge the electric vehicle at a plurality of charging speed tiers by the charging station. The system and method also include determining a price difference between the price to charge the electric vehicle at a fast charging speed tier and a slower charging speed tier. The system and method further include adjusting the electric vehicle charging speed to the fast charging speed tier upon determining that the price difference is equal to or below a charging price delta threshold.

摘要： A method for controlling a current being fed to a battery pack including a plurality of battery cells connected in series and providing an output battery voltage includes the steps of: feeding a relatively low current through a resistor being arranged in series with the battery pack; and measuring the voltage across the resistor, thereby obtaining a value of the current. A system for controlling a current being fed to a battery pack is also provided.

摘要： A dynamic capacitive power transfer system for an elevator that can realize the real-time powering of the elevator when it is in the moving status. It includes a metal track along the building side as the power transmitter and a piece of metal at the elevator side as the power receiver. There is a gap between the transmitter and receiver, and up to kW power can be transferred wirelessly and efficiently to serve the air conditioner, lightning, and other electronic devices in the moving car. The steel wheels and ropes may be used to connect the moving car to the earth ground, which contributes to form the current returning loop. It eliminates the electric cables and the corresponding flexible cable carrier system for the linear movement.

摘要： A vehicle controller is applied to a vehicle having an engine, a transmission, a clutch connecting and disconnecting a crankshaft of the engine and an input shaft of the transmission to each other, a vehicle wheel connected to a drive axle of the transmission, and an electric motor disposed to be capable of transmitting torque to the crankshaft The vehicle controller controls driving of the electric motor such that a rotation speed of the engine is reduced when an operation state of the engine shifts from operation to stop. The vehicle controller controls rotation of the crankshaft so as to avoid coincidence between a crank angle and a top dead center angle of the engine in a vibration amplification region amplifying an amplitude of vibration generated when the operation state of the engine shifts to the stop.
