The invention relates to a brushless motor drive device that performs switching determination of energization modes of a three-phase brushless motor according to a sensorless method, and a drive method thereof. A pulse induced voltage induced in a non-energized phase of three phases by a pulse voltage is compared with a threshold to determine the switching timing of the energization modes. Here, by limiting a duty ratio of a voltage application to equal to or greater than a lower limit, a situation in which the pulse induced voltage is sampled while the pulse induced voltage is oscillating is avoided, and a situation in which the pulse induced voltage falls below a voltage detection resolution is avoided. As a result, determination of energization mode switching timing based on a pulse induced voltage can be performed more stably.

A controller judges whether or not a passing power of a DC/DC converter falls within a reduced response performance area for the number of active phases as of the present moment. When the controller determines that the passing power of the DC/DC converter falls within the reduced response performance area, the controller determines the number of phases which avoids the driving within the reduced response performance area, and outputs a command for switching to the determined number of phases (phase switching command) to the DC/DC converter.

A method and system for use with a vehicle battery pack having a number of individual battery cells, where the method estimates, extrapolates or otherwise determines individual cell resistances. According to an exemplary embodiment, the method and system use a voltage and temperature reading for each of the individual battery cells, as well as a voltage and current reading for the overall battery pack to determine one or more cell resistance values, such as a minimum and maximum cell resistance for the battery pack. This approach relies upon temperature deviations in the battery pack to make assumptions or estimates regarding individual battery cell resistances. By having individual cell resistance values—instead of using an overall pack resistance value and building in a buffer to account for cell variations—better and more accurate cell-level data can be obtained that, in turn, can improve charging, discharging, cell balancing and/or other battery-related processes.

A vehicular energy management system (EMS) determines a net total power from a traction drive load, an auxiliary device load, and a regenerative power. If the net total power is a net supply power, the EMS causes regenerative power to be provided to a power source and energy source in a controlled manner to initially charge the power source to a desired state-of-charge (SOC) and then subsequently charge the energy source. If the net total power comprises a net power load, the EMS causes power to be drawn from the power source and the energy source, with a split of the power being drawn from the power source and the energy source being based on a magnitude of the net power load. The EMS adjusts/maintains the SOC set-point of the power source and the DC link voltage based on vehicle speed and relative altitude of travel of the vehicle.

By using the tire, the area inside the tire, the tire rim, or the wheel as the inductive pick-up for a powered roadway system the prior art problems are solved. Namely, since the tire/wheel is always in contact, or near contact with the road, the air gap is reduced to a minimum, and substantially fixed, distance. By mounting the secondary on the perimeter of a wheel, relative motion between the road and inductor is minimized In addition, the pick-up can be encased in the tire, eliminating the problem of road debris, snow and ice entirely. Also, some heating of the tire due to electrical losses may enhance traction and tread performance on snowy or wet roads. In all configurations, the vehicle's wheel suspension adjusts vertically adjusting for road imperfections and obstacles.

Provided herein is a vehicle drive force control. When a driver requests to start the vehicle with the brake OFF and depresses the accelerator pedal, a target drive torque exceeds a gradient load. To avoid excess current being supplied to the motor, the upper limit of motor speed, which is the input speed of a second clutch, is set to a value less than a slip detectable limit value at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed) is set to a value equal to or greater than the slip detectable limit value so that the required driving force can be achieved by the gradient load corresponding driving force control.

In order to prevent elements from being damaged by electrical energy when a regenerative braking force is generated, an electric motor ( 108 ) in a vehicle power supply device ( 100 ) converts the kinetic energy of a vehicle ( 10 ) into electrical energy to generate a regenerative braking force, and an inverter ( 103 ) converts AC electrical energy outputted by the electric motor ( 108 ) into DC electrical energy. The converted DC electrical energy accumulates in a battery ( 106 ) via first switches ( 105 a, 105 b ) and second switches ( 107 a, 107 b ). A control unit ( 109 ) switches the second switches ( 107 a, 107 b ) on when electrical energy resulting from a regenerative braking force generated by the electric motor ( 108 ) is capable of accumulating in the battery.
