Vehicle power management system
An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.
CHARGING SYSTEMS AND METHODS FOR ELECTRIC VEHICLES
Systems and method are provided for controlling a vehicle having one or more batteries. In one embodiment, a method includes: receiving, by a processor, data from at least two of a user of the vehicle, the vehicle, one or more charging stations, and one or more vehicle services; determining, by the processor, optimization criteria based on the received data; computing, by the processor, a charging route solution based on the optimization criteria; and generating, by the processor, interface data for presenting the charging route solution to the user of the vehicle.
VEHICLE BATTERY ANALYSIS SYSTEM
In one embodiment, a vehicle battery diagnostics system forecasts a future state for a battery by monitoring, over a period of time, one or more of voltage, current or temperature signals from at least one battery of the vehicle, storing information from the voltage, current or temperature signals as time-series data, obtaining a forecasting model from a server, the forecasting model indicating at least one shapelet feature that corresponds to a forecast categorization, identifying, in the time-series data, a shapelet that matches the at least one shapelet feature to a degree exceeding a predetermined similarity threshold, and providing a notification indicating the forecast categorization.
REGENERATIVE BRAKING CONTROL APPARATUS FOR ELECTRICALLY-POWERED VEHICLE
A regenerative torque control unit is configured to reduce a regenerative torque and increase a rising gradient of the regenerative torque at a start of regeneration when a road surface friction coefficient acquired by a road surface friction coefficient acquisition unit is low as compared to when the road surface friction coefficient is high. Thus, it is possible to suppress occurrence of a slip on a low μ road, and it is less likely to provide a feeling of strangeness from a change between a low μ road and a high μ road.
Apparatus, method and article for a power storage device compartment
A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.

Vehicle control unit (VCU) and operating method thereof
Disclosed are a vehicle control unit (VCU) and an operation method thereof that calculate a speed variation of a vehicle based on input information, predict an average speed of the vehicle based on the calculated speed variation, generate a first speed profile based on the predicted average speed, and generate a second speed profile by applying speed noise information to the first speed profile.
Battery management system for vehicle, battery management method thereof and vehicle including the same
A battery management system for a vehicle, a battery management method thereof and a vehicle including the same, which can vary a state of charge (SOC) of a battery in accordance with a location of a recharging station are disclosed. The battery management system includes: a position information acquisition unit for acquiring position information of a recharging station and the vehicle; a storage for storing a hilly area recharging station list comprising position information of hilly area recharging stations and learned full SOC values; and a controller for controlling the position information acquisition unit and the storage. The controller checks whether a recharging station where recharging of the vehicle is executed is a hilly area recharging station, and restricts a full SOC in order to avoid restriction of regenerative braking according to downhill road travel, thereby enhancing fuel economy and safety.
Vehicle maneuver planning based on predicted battery power
A vehicle includes a traction battery and a controller. The controller, responsive to a command to enter a highway, confirmation the traction battery can output power to accelerate the vehicle to enter the highway via an entrance at a same speed as traffic on the highway in a vicinity of the entrance, and an increase in temperature beyond a threshold of the traction battery predicted to occur on the highway due to expected commands to maintain the same speed on the highway with power from the traction battery, increases cooling of the traction battery prior to entering the highway.
METHOD OF IMPROVING FUEL EFFICIENCY OF FUEL CELL ELECTRIC VEHICLE BY USING NAVIGATION INFORMATION, AND APPARATUS AND SYSTEM THEREFOR
Disclosed are a method of improving fuel efficiency of a fuel cell electric vehicle, and an apparatus and a system therefor. The method includes collecting navigation information and vehicle speed information, calculating a coasting line when a specified event point is detected based on the navigation information, determining whether deceleration is necessary by comparing a current traveling speed with a coasting line speed corresponding to a current location, and changing a criterion for determining whether to enter a fuel cell stop (FC STOP) state when the deceleration is necessary as a determination result.
