  • Patent number: 9925884
    Abstract: Methods and systems are described to control the use of electrical power when charging a traction battery. A vehicle module can drive the contactor coils with two set-points for controlling the power into the contactor coils, namely, a travel or vehicle “on” set point and a charging, vehicle “off” set point. In use, full power is initially applied to the coils to guarantee immediate closure of the contactor. During charging and after closing the contactor, the power is set at the charging, vehicle “off” set point. The travel or vehicle “on” set point is higher than the charging, vehicle “off” set point. Using the charging, vehicle “off” set point reduces electricity consumption. The vehicle “on” set point is at a higher electrical level as it must maintain closure under worst-case vibration and shock conditions considering mounting location, contactor orientation, as well as other characteristics of the vehicle and contactor.

  • Patent number: 9616879
    Abstract: In a vehicle, a controller divides a route into route segments. The controller operates a traction battery over the route segments to achieve a target state of charge upon completion of one of the route segments. The target state of charge is based on a target battery power defined by a classification for each of the route segments including the one of the route segments according to a set of fuzzy rules applied to vehicle acceleration and road grade associated with the route segments. Fuzzy rules may be applied to the classification for each of the route segments.

  • Patent number: 9573454
    Abstract: A powertrain for a vehicle includes an engine and a method of assembling the powertrain includes providing the engine. A starter mechanism is selectively operable to start the engine. A motor-generator includes an adapter to dispose the motor-generator and the starter mechanism in alternative assembly configurations being a first assembly configuration and a second assembly configuration. The first assembly configuration is when the starter mechanism is coupleable to the adapter to selectively transfer torque from the motor-generator through the adapter and the starter mechanism to start the engine. The second assembly configuration is when the starter mechanism is spaced from the adapter to operate independently of the motor-generator such that the starter mechanism selectively transfers torque to start the engine.

  • Patent number: 9534605
    Abstract: In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical components provided in a fluid circuit by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. When the electric pump is operating, a diagnostic can be performed to determine system integrity. According to one embodiment, an actual quantity provide to the circuit is determined; an expected quantity is estimated; and a fault is determined when the actual and expected quantities differ by more than a predetermined amount. The fault may indicate a leak or plug in the fluid circuit or a failure of a component in the fluid circuit.
