Abstract: A vehicle is disclosed comprising a battery and a controller. Projected battery impedance parameters are calculated based on predetermined parameter values and historical parameter values generated by a battery parameter estimation model. The values may be weighted according to time data associated with the historical impedance parameter values and a temperature of the battery. Recent historical impedance parameter values may affect the projected battery impedance parameter values more than older historical impedance parameter values. The model is initialized with projected parameter values at vehicle initialization. Battery power capability is calculated using the projected parameter values for a period of time following vehicle initialization. After the period of time following vehicle initialization, battery power capability is calculated using impedance parameters generated by the model. The period of time following vehicle initialization may end when the model output has converged to a stable solution.

Abstract: A pillar assembly for a vehicle includes an outer panel, a reinforcement and an inner panel. The outer panel extends from a roof to a rocker. The reinforcement is attached to the outer panel and extends from the roof to a lower end that is spaced from the rocker. The reinforcement defines an opening in one side extending upwardly from the lower end of the reinforcement to a hip seating reference point level. The inner panel encloses the lower end of the reinforcement in conjunction with the outer panel. The pillar reinforces the assembly to facilitate inwardly collapsing a lower portion of the pillar to a greater extent than an upper portion of the pillar in a side impact collision.

Abstract: A service warm-up feature warms transmission fluid to normal operating temperature faster than normal idle without requiring continuous technician attention. This facilitates checking the transmission fluid level. The feature increases the warm-up rate by commanding an increased line pressure and an increased idle speed, which causes more heat to be generated as the fluid flows through restrictions at an increased flow rate with an increased pressure drop. The warm-up rate may be further increased by holding the turbine shaft stationary to increase torque converter heat generation. Various precautions prevent accidental vehicle movement.

Abstract: A hybrid vehicle includes an engine and an electric machine selectively coupled to the engine via a disconnect clutch. At least one controller issues commands to control the engine, the electric machine, and the clutch. During cruise control, the controller controls the torque output of the engine and electric machine, as well as the slipping of the clutch, such that the speed of the vehicle is attempted to be maintained at the cruise control set speed. For example, when the engine is off and additional torque is necessary to maintain the speed, the controller can issue a command to change the state of the engine from off to on. When the vehicle experiences oscillations in road load, the controller delays or inhibits changing the on/off state of the engine for an amount of time that is based on the oscillation associated with road load.

Abstract: A discontinuous pulse width modulation technique is used in a controller to control an inverter that converts DC battery power to AC power to operate an electric motor, e.g., in a hybrid electric vehicle. The discontinuous pulse width modulation technique uses only one of the two zero state voltage vectors in its calculations whereas traditional pulse width modulation uses both zero state voltage vectors. The use of a single zero state voltage vector can result in one of a group of switches in the inverter remaining in a constant state during a complete duty cycle while still providing the commanded voltage vector to the electrical motor. As a result losses due to switching can be reduced.
