    摘要： A method for operating a brake system of a vehicle, where the vehicle has an electric machine usable for a regenerative braking of the vehicle and a drive unit usable in an overrun operation for an overrun braking of the vehicle, includes detecting an initiation of deceleration of the vehicle and detecting a driving situation suitable for regeneration. The method further includes initiating the overrun operation of the drive unit and the overrun braking of the vehicle and activating the regenerative braking so as to achieve a setpoint total regeneration torque. The regenerative braking is activated only after a limit value for a difference between an actual overrun regeneration torque by the overrun braking and a setpoint overrun regeneration torque is undershot.

    摘要： An auxiliary power system for a motor vehicle includes a power generator that generates electricity to charge one or more auxiliary power system batteries. The motor vehicle includes an engine and drive train that distributes power from the engine to the drive wheels. The drive train can include a transmission, a drive shaft and a differential that connects the engine to the drive wheels. The power generator can be connected to the drive train (e.g., the transmission, the drive shaft or the differential) to draw power to generate electricity as well as to apply braking loads on the drive wheels to increase the ability to stop the motor vehicle.

    摘要： A drive system includes an engine, an alternator coupled to the engine, the alternator being configured to power at least one auxiliary load, a traction motor system operatively coupled to drive wheels of the vehicle, the traction motor system being configured for receiving primary electrical power from the alternator and for propelling the vehicle in response to the primary electrical power, and a motor electrically connected to the traction motor system and mechanically coupled to the engine. The motor is configured to receive electrical power from the traction motor system in a dynamic braking mode of operation of the traction motor system and to communicate power to the engine during the dynamic braking mode.

    摘要： A vehicle control device includes: an engine and a first motor generator from both of which a driving force for traveling is output to drive wheels; and an electricity storage device that storages electric power for driving the first motor generator. When a vehicle weight is in a reference state at a time of deceleration braking, the first motor generator is mainly caused, out of the first motor generator and the engine, to generate a braking force, and when the vehicle weight is greater than that in the reference state, the engine is mainly caused, out of the first motor generator and the engine, to generate the braking force. Thus, a sufficient braking force can be obtained while an input limit of the electricity storage device is prevented from being reached.

    摘要： An in-vehicle power supply device includes an electric generator, a main power supply, a DC/DC converter, a power storage unit connected with the electric generator via the DC/DC converter, and a controller for controlling the DC/DC converter. The DC/DC converter is operable to store, in the power storage unit, regenerative electric power generated by the electric generator, and to discharge the stored regenerative electric power from the power storage unit to the main power supply and the load. The controller is operable to stop the DC/DC converter when a charging-status value indicating a charging status of the power storage unit is not larger than a predetermined lower limit value. The controller is operable to activate the DC/DC converter when the charging-status value is larger than the lower limit value and the vehicle ends deceleration. The controller is operable to activate the DC/DC converter when a speed of the vehicle is not lower than a predetermined speed and an accelerator position of the engine is not larger than a predetermined accelerator position even if the charging-status value is not larger than the predetermined lower limit value. The in-vehicle power supply device is capable of reducing power consumption of the DC/DC converter, with the recovery efficiency of the regenerative electric power being held, thereby resulting in a higher efficiency of the device.
