A vehicle information display may include a split braking gauge for conveying information relating to braking operation and efficiency to assist drivers in maximizing energy capture during braking in vehicle with regenerative braking systems. The split braking gauge may incorporate a side-by-side or stacked configuration for conveying both regenerative braking and friction braking values. The split braking gauge may include fixed thresholds or boundaries associated with dynamic threshold values that can change based on current vehicle operating conditions.

An ECU sets a voltage of an inverter side in an external supply mode to be less than a voltage of the inverter side when a first MG supplies the electric power equal to the electric power in the external supply mode in a traveling generation mode.

In a method for controlling a vehicle drive unit having at least two individual drives and a vehicle control unit, a continuous torque comparison between a permissible torque M.sub.Zul and a further torque is performed by the control unit. The permissible torque M.sub.Zul is continuously compared to setpoint torques M.sub.setpoint,V and M.sub.setpoint,E for the least two individual drives.

A vehicle display device is provided in an electric vehicle including a friction brake and includes: a loss energy calculation module that calculates a loss energy released from the electric vehicle on the basis of an actuation state of the friction brake; a consumption calculation module that calculates an energy consumption consumed by the electric vehicle on the basis of the loss energy; a first efficiency calculation module that calculates a first energy efficiency on the basis of a travel distance and an energy consumption in a first period; a second efficiency calculation module that calculates a second energy efficiency on the basis of a travel distance and an energy consumption in a second period shorter than the first period; and a display control module that controls a display content of an onboard display on the basis of an efficiency difference between the first and second energy efficiencies.

A hybrid vehicle includes an engine; a traction battery; and a controller or a vehicle control system having a controller. The controller is programmed to respond to a state of charge (SOC) of the traction battery. When the SOC is greater than a predicted SOC the controller is programmed to decrease a SOC threshold at which the engine is shut down to reduce the SOC. The SOC threshold is defined by a difference between a maximum SOC and an expected change in the SOC associated with predicted regenerative energy for a drive cycle.

A filter processor of a control apparatus for a rotary electric machine filters target torque for the rotary electric machine to suppress a vibrational frequency component of a drivetrain using a filter having a frequency transfer characteristic. A controller performs drive control of the rotary electric machine according to the filtered target torque. A parameter calculator calculates, according to a running condition of the vehicle, a parameter associated with a request value for responsivity of output torque of the rotary electric machine with respect to the target torque. A variable setter variably sets the frequency transfer characteristic of the filter to decrease a degree of attenuation of the vibrational frequency component with an increase of the request value for the responsivity of the output torque.

A rotating electric machine includes a stator having a stator coil and a rotor provided rotatably around a specific rotation axis with respect to the stator. The rotor includes a plurality of magnets, a plurality of magnetically-assisted salient pole members provided between poles of any adjacent two magnets from among the plurality of magnets, and a magnetoresistance variation unit provided in the magnetically-assisted salient pole member along an axial direction of the rotation axis at a position offset in a circumferential direction of the rotation axis from a q-axis passing through a salient pole center of the magnetically-assisted salient pole member. The amount of offset of the magnetoresistance variation unit from the q-axis varies depending on positions of the magnetically-assisted salient pole members so that torque fluctuations cancel each other when power is applied.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

A vehicle includes a traction motor coupled to a driveline. An engine and a generator are coupled to the driveline through a planetary gearset. A controller commands the traction motor torque based on a difference between a driver torque demand and an estimated powertrain torque. The estimated powertrain torque is based on an error between actual and estimated engine speed and an error between actual and estimated generator speed. The estimated powertrain torque may be further based on commanded or estimated engine torque and generator torque. The estimated powertrain torque may utilize a state estimator to calculate internal states based on the errors.

A power transmission device of a work vehicle includes a generator, a motor, and an energy storage unit. The energy storage unit stores electricity generated by the generator. A forward/backward travel switch operation device receives an instruction for forward or backward travel from an operator. A vehicle speed detection unit detects the speed of the vehicle. A control unit includes an energy management requirement determination unit. The energy management requirement determination unit determines, on the basis of the difference between a target electricity storage amount and a current electricity storage amount in the energy storage unit, the energy management required power required by the power transmission device for charging the energy storage unit. The energy management requirement determination unit increases the target electricity storage amount when a first travel direction according to the instruction and a second travel direction determined from the vehicle speed are different.
