A revolution position of an engine is set to a revolution position suitable for a start. A control apparatus for an electric vehicle includes an engine, a motor which generates electricity, a battery, a first controller which drives the engine, a second controller which drives the motor, and a sensor. The second controller confirms a relative position relationship between a revolution position of the engine and a rotation position of the motor by acquiring information of the revolution position of the engine from the first controller during the electricity generation driving by the motor and monitors the revolution position of the engine based on the relative position relationship and a signal from the sensor, and the second controller checks the stop position of the engine through the monitoring of the revolution position of the engine when the motor finishes the electricity generation driving.

A regenerative braking control method and a regenerative braking control device of the present invention control a drive source that generates a regenerative brake force in such a manner that an upper limit of regenerative deceleration when a driver executes manual control becomes smaller than an upper limit of regenerative deceleration when automatic control is executed.

Closing timing of an intake port is changed without using a variable valve timing mechanism. An electric vehicle includes an engine for electricity generation in which closing timing of an intake port maximizes intake air charging efficiency in a specific revolution speed region, a sensor which outputs a signal related to a revolution speed of the engine, a controller which drives the engine at a revolution speed based on the signal of the sensor, a requested electricity generation amount being satisfied at the revolution speed, and a motor which applies a positive or negative torque to the engine. When the engine is driven in a revolution speed region other than the specific revolution speed region, the controller uses the motor to apply a positive or a negative torque to the engine in an intake stroke to change the closing timing of the intake port to increase intake air charging efficiency.

A control method controls a series hybrid vehicle in which a drive motor and an internal combustion engine are supported in a vehicle body via a plurality of mount members in an integrated state. The control method using a controller generates electric power using an electric power generation motor, and drives the electric power generation motor using motive power of the internal combustion engine. The control method drives a drive wheel with the drive motor using the generated electric power, and causes the drive motor to generate regenerative torque during deceleration. In the control method, the regenerative torque is generated by the drive motor such that an upper limit of the regenerative torque is restricted to a magnitude at which an engine rotational speed where resonance occurs on the vehicle body floor.

A control method for a hybrid vehicle includes a generator and an electric motor, the generator being configured to charge a battery by use of power of an engine, the electric motor being configured to drive driving wheels by electric power of the battery. The control method having driving the engine at a first rotation speed when a charging amount of the battery decreases to a first charging threshold; changing the engine to driving at a second rotation speed larger than the first rotation speed when the engine is driven at the first rotation speed and the charging amount decreases to a second charging threshold smaller than the first charging threshold; and continuing driving of the engine until the charging amount becomes equal to or more than a charging end threshold larger than the first charging threshold.

A voltage controlled aircraft electric propulsion system includes an electric propulsion system. The voltage controlled aircraft electric propulsion system may include electric propulsors providing thrust for the aircraft. In hybrid systems, a gas turbine engine may also be included. The electric propulsion system may include at least one electric generator power source, at least one propulsor motor load, and at least one stored energy power source, such as a battery. The propulsor motor load may be supplied power from a power supply bus. The voltage of the power supply bus may be adjusted according to an altitude of the aircraft while maintaining a substantially constant current flow to the propulsor motor load. Due to the adjustment to lower voltages at increased altitude, insulations levels may be lower.
