Abstract: A trailer backup assist system for vehicles utilizes surface slope data to provide an alert to an operator if a problematic operating condition is present and/or imminent while the vehicle is backing up with a trailer attached thereto. The trailer backup assist system may also be configured to utilize surface slope data to control steering, braking, or other vehicle operating parameter while the vehicle is backing up with a trailer attached thereto. The trailer backup assist system may also be configured to generate a warning and/or control the vehicle if a jackknife condition is imminent. The surface slope data may be obtained utilizing sensors on the vehicle, or the surface slope data may be obtained utilizing a database that includes topographical data.

Abstract: A driving pattern based plug-in hybrid electric vehicle (PHEV) energy consumption preplanning process enables a PHEV trip-oriented energy management control (TEMC) to utilize scalable levels of available trip foreknowledge in order to optimize the onboard energy (fuel and electricity) usage. The preplanning process generates an optimal battery state-of-charge (SOC) depletion profile for a given trip to be traveled by a PHEV. The preplanning process may generate the battery SOC profile using a driving pattern based dynamic programming (DP) algorithm. The TEMC controls the onboard energy usage in accordance with the battery SOC profile, which is optimized for the trip. The preplanning process makes use of spatial domain normalized drive power demand (SNDP) (or S-NDP) distributions in which each set of distributions is indicative of a respective driving pattern. The trip foreknowledge is used to select the driving pattern best representative of the driving process for the trip.

Abstract: Hybrid-electric and pure electric vehicles include a traction battery. During vehicle operation, impedance parameters of the traction battery may be estimated. To ensure accurate estimation results, certain persistent excitation criteria may be met. These conditions may not always be met, in which case active excitation of the traction battery power demand may be initiated. The invocation of active battery excitation may be based on a variability of estimates of a battery parameter and an age of a most recent estimate of the battery parameter. As the variability of the parameter estimates increases, the time between active battery excitation requests may decrease.
