A method for operating an electrically operated or also electrically operable motor vehicle provided with a rechargeable electric energy storage device associated with the drive motor of the motor vehicle. A target charging state is determined for the energy storage device and an operating strategy is determined for a route that is calculated, entered or predicted for the next trip, by which recuperative deceleration is enabled with a specifiable minimum amount for deceleration processes occurring along the route. A total mass of the motor vehicle, including optionally a trailer connected to the motor vehicle, deviating from an input normal value and an air resistance of the motor vehicle deviating from a predetermined normal value are taken into account.

A processing unit segments the route into a plurality of sections. It is, for each section, obtains a set of route section characteristic values, R.sub.SCV, that will impact the energy consumption of the vehicle whilst driving within the section, obtains a set of vehicle energy consumption values, V.sub.ECV, that will impact the energy consumption of the vehicle whilst driving within the section at least partly based on R.sub.SCV, estimates a first probability distribution, P.sub.1, of the energy consumption for the vehicle whilst driving within the section based on R.sub.SCV, V.sub.ECV, and a first set of traffic information values, T.sub.1, within the section, estimates a second probability distribution, P.sub.2, of the energy consumption for the vehicle whilst driving within the section based on R.sub.SCV, V.sub.ECV, and a second set of traffic information values, T.sub.2, within the section, estimates a traffic flow indicator, I.sub.TF, for the section based on R.sub.SCV, V.sub.ECV and a third set of traffic information values, T.sub.3, within the section, and determines a route section probability distribution, P.sub.RS, of the energy consumption for the vehicle whilst driving within the section based on the relation between I.sub.TF, P.sub.1, and P.sub.2.

A management method of a battery system includes determining whether a wireless communication failure occurs between a master battery management system (BMS) and at least one of a plurality of slave battery management systems (BMSs); receiving road condition information of where the vehicle equipped with the battery system is currently positioned if the wireless communication failure occurs; determining whether the vehicle is on the road based on the road condition information; setting a first failure confirmation time if the current position of the vehicle is on the road; setting a second failure confirmation time if the current position of the vehicle is not located on the road; and entering a safety mode if a wireless communication failure section from the time when the wireless communication failure occurs to the current time reaches the first failure confirmation time or the second failure confirmation time.

This disclosure relates to an electrified vehicle configured to selectively deactivate a restricted power mode based on an acceleration request, such as an imminent or current acceleration request. A corresponding method is also disclosed. An example electrified vehicle includes a battery and a controller configured to apply a restricted power mode when a state of health of the battery is below a predefined lower threshold. Further, when in the restricted power mode, the controller is configured to limit an amount of power drawn from the battery. Additionally, the controller is configured to selectively deactivate the restricted power mode in response to a signal indicating a current or imminent request for acceleration of the electrified vehicle requiring power to be drawn from the battery above an upper limit of the restricted power mode.

A method for inertia drive control is provided. The method includes performing advanced inertia drive control by an inertia drive controller. The controller detects a speed reduction event during road driving of a vehicle, lane division together with road type division for a road, and performs inertia drive control guide and the inertia drive control based on drive conditions of lane change and lane maintenance.

A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.

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.

Systems and methods for reducing a current speed of a vehicle that can operate on solar energy to increase solar energy collection. The system may include a photovoltaic (PV) panel configured to receive sunlight to drive an electric motor, a solar loading sensor configured to detect solar load, a global position system (GPS) sensor configured to detect vehicle location data, a speed sensor configured to detect vehicle speed, and an electronic control unit (ECU) connected to the electric motor, the solar loading sensor, the speed sensor, and the GPS sensor. The ECU may determine whether the vehicle is exposed to solar load greater than a predetermined threshold value and, if so, present a driver of the vehicle a minimum acceptable speed to select based on sensor data and a difference of solar energy collection between the minimum acceptable speed and the current speed.

An operating system for a vehicle having an electric vehicle (EV) drivetrain and a plurality of electrically-powered accessories is described. A controller determines, via a navigation system, a target off-road trail segment, and characterizes the subject vehicle, ambient conditions, and the target off-road trail segment to determine an estimated consumption of electric energy for the vehicle to operate over the target off-road trail segment. The EV drivetrain and the electrically-powered accessories are controlled during operation of the vehicle on the off-road trail segment based upon the estimated consumption of electric energy for the subject vehicle. This is done to minimize a likelihood of a low SOC event for the DC power source for the trail segment and to avoid a low battery state at a location that is distal from a charging station.
