The invention relates to a method for protecting an on-board electrical network of a truck having a base-line equipment provided by a truck manufacturer, and having base-line loads having a current consumption, an auxiliary equipment fitted a posteriori by a truck body builder, and having auxiliary loads having a current consumption, and a battery. The method further comprises, when the engine of the truck is ON: determining that the engine is to be turned off, determining a total current consumption of the truck, determining the battery maximum capacity, if the total current consumption is lower than the battery maximum capacity, turning off the engine, and, if the total current consumption is higher than the battery maximum capacity, reducing the current consumption of at least one adjustable auxiliary load.

A vehicle control system includes at least one sensor and a power supply control system. The sensor is on board a vehicle system and configured to generate vehicle data relating to a condition or parameter associated with the vehicle system. The power supply control system is configured to control one or more power supplies on board the vehicle system and to receive the vehicle data from the at least one sensor. The power supply control system is also configured to compare the vehicle data to one or more criteria relating to vehicle movement, and, in response to a determination that the vehicle data meets the criteria and receipt of a signal indicative of the vehicle system carrying (or being configured to carry) cargo of a predetermined material, generate a control signal to deactivate at least one of the power supplies.

A method includes monitoring one or more of an ambient condition or an operational condition of a vehicle system while the vehicle system is stationary and a propulsion system of the vehicle system is operating at an idle speed, determining whether the one or more of the ambient condition or the operational condition satisfy one or more reduced auxiliary or parasitic load criteria, reducing one or more of an auxiliary load or a parasitic load responsive to determining that the one or more ambient condition or the operational condition satisfy the one or more reduced auxiliary or parasitic load criteria, and subsequently reducing the idle speed at which the propulsion system is operating to a slower speed following reducing the one or more of the auxiliary load or the parasitic load.

A travel support control device: creates a travel support plan in which one of travel modes including a CD mode and a CS mode is assigned to each travel section based on look-ahead information generated for a travel route to allow a hybrid electric vehicle to travel and calculates a total distance of electric traveling on the travel route; creates a travel support plan for travel sections to a travel section immediately before an information non-acquirable area in which information required for creating the look-ahead information is not acquirable and calculates the total distance of electric traveling on the travel route, when the information non-acquirable area is included in the travel route; and stops switching of the travel mode based on travel support control and continuously calculates the total distance of electric traveling on the travel route, when the hybrid electric vehicle is traveling in the information non-acquirable area.

A vehicle includes an electrical powertrain, a heater, at least one cooling loop, and a controller. The heater is configured to heat a vehicle cabin. The at least one cooling loop is configured to transport waste heat from at least one subcomponent of the electrical powertrain to the vehicle cabin. The controller is programmed to, in response to a command to heat the vehicle cabin and a command to operate in an economy mode, shut down the heater and operate the at least one cooling loop to transport the waste heat to the vehicle cabin. The controller is further programmed to, in response to the command to heat the vehicle cabin and an absence of the command to operate in the economy mode, operate the heater to heat the vehicle cabin.

Systems and methods are provided for controlling a hybrid powertrain of a hybrid vehicle, and may include: determining a value of a drive request for a combustion engine of the hybrid vehicle; determining electrical loading on batteries of the hybrid vehicle; adjusting operation of an accessory of the hybrid vehicle to reduce the electrical load of that accessory on the batteries of the hybrid vehicle when the drive request value is above a determined drive request threshold amount and the electrical loading on batteries of the hybrid vehicle is above a power loading threshold; and directing at least some of the power saved by adjusting operation of the accessory from the batteries of the hybrid vehicle to a drive motor of the hybrid vehicle to provide motive force for the vehicle.

A method for operating a vehicle includes obtaining personal data associated with a user of the vehicle, obtaining operating data for the vehicle, determining a driver behavior recommendation to reduce emissions of the vehicle based at least in part on the personal data and the operating data, and presenting the driver behavior recommendation on an interface.

A method for operating a hybrid vehicle includes obtaining propulsion switching data descriptive of a state of one or more vehicle systems for switching power flow of an internal combustion engine and an electric machine. The propulsion switching data may be used to provide a driver behavior recommendation and/or an actual environmental impact of the hybrid vehicle.

A hybrid vehicle includes an electric motor, a power storage device, an engine, and a controller. The controller executes switching control for switching control modes. The controller adds, to a first traveling distance, a traveling distance that is obtained when a state in which the engine is not operating and a power storage amount of the power storage device is higher than a threshold continues, and adds, to a second traveling distance, a traveling distance that is obtained when a state in which the engine is not operating and a charge depleting mode is selected continues.

A system and method for operating a hybrid vehicle that shuts down an internal combustion engine during idle and slow speed operations and instead drives a power transmission with an electric traction motor. A vehicle operating at higher speeds, under increased operating demands, or other operating conditions automatically switches from electric propulsion to internal combustion engine propulsion. This operational mode is configurable and at all times seamless to the driver and vehicle operations. By designating the low speed, low demand operation of the vehicle to the more efficient electric mode, fuel consumption can be reduced, and overall vehicle efficiency can be maximized.
