A vehicle with a hybrid drivetrain including a fuel-fed engine coupled to a first drive axle, an electric motor coupled to a second drive axle and an APU for providing electrical power at stopover locations, and further including a controller for determining a location of the vehicle, a location of a stopover location, determining a target SOC of a battery for operating the APU at the stopover location and operating a hybrid control system to provide the target SOC for the vehicle at the stopover location.

A vehicle state display device for a vehicle includes an output limiting unit that limits an output of the vehicle when charge of a battery is equal to or smaller than a first value and a battery state display unit that displays a state of the battery. The battery state display unit switches and displays a first display mode indicating that the state of charge of the battery exceeds a second value that is larger than the first value, a second display mode indicating that the state of charge of the battery is equal to or smaller than the second value and exceeds the first value and the output of the vehicle may be limited, and a third display mode indicating that the state of charge of the battery is equal to or smaller than the first value and the output of the vehicle is being limited.

A method for assisting piloting beyond an altitude that can be reached with only the capabilities of a thermal power plant of a rotorcraft, by supplying power from an electrical power plant. After defining a take-off point of the rotorcraft and a target point, and their respective altitudes, a determination of a first maximum altitude that can be reached by the rotorcraft using only the thermal power plant is carried out according to a first altitude law. Then, an estimate of a second maximum altitude that can be reached by the rotorcraft using the thermal power plant and the electrical power plant jointly driving each rotor of the rotorcraft is made according to a second altitude law. If the second maximum altitude is higher than the altitude of the target point, the rotorcraft can fly to the target point.

An electrified vehicle includes an engine configured to selectively apply propulsive torque to wheels of a first axle of the vehicle, a first electric machine configured to selectively apply propulsive torque to the wheels of the first axle of the vehicle, a second electric machine configured to selectively apply propulsive torque to wheels of a second axle of the vehicle, a traction battery electrically coupled to the first and second electric machines, and a controller configured to control engine torque, first electric machine torque, and second electric machine torque to provide a driver demand torque at the wheels of the first and second axles. The controller allocates torque between the first and second electric machines based on associated combined losses of the first and second electric machines and maintaining the torque of the first and second electric machines in the same direction.

To sufficiently exert charging and discharging performance of a cell while reliably protecting the cell, a battery controller determines ΔVlimit which is a limit value for a difference between a CCV and an OCV of a cell module, which is a secondary cell, and determines at least one of an upper limit voltage and a lower limit voltage of the cell module. An allowable current of the cell module is calculated based on the ΔVlimit and at least one of the upper limit voltage and the lower limit voltage determined in this manner.
