A vehicle includes a battery, an electric machine, an electrical outlet, and a controller. The electric machine is configured to charge the battery. The electrical outlet is configured to draw power from the battery to power an external device. The controller is programmed to adjust a rate at which the electric machine charges the battery based on a power consumption at the electrical outlet exceeding a threshold and a battery degradation value.

A braking control device of an industrial vehicle includes a travel motor configured So generate regenerative braking force and a mechanical brake configured to generate mechanical braking force as a braking unit and including a battery configured to be charged by the regenerative braking force. The device is configured to acquire vehicle speed information of the industrial vehicle, acquire a regenerative current of the travel motor, execute autonomous driving with a required braking force including the regenerative braking force for causing a vehicle speed of the industrial vehicle descending a slope to be a target vehicle speed based on the vehicle speed information, and adjust distribution of the mechanical braking force in the required braking force so that the acquired regenerative current is equal to or less than an upper regenerative threshold value smaller than a maximum regenerative current.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Methods and systems are provided for emissions reduction in a vehicle. In one example, a method includes pre-emptively adjusting engine operating parameters in response to an anticipated emissions causal event. The emissions causal event lasting for less than a threshold period of time or less than a threshold distance.

An electric machine and internal combustion engine are coordinated to provide traction control for an automotive vehicle. A propulsive torque limit is set by a controller during a loss of traction. When the machine torque limit is greater than the propulsive torque limit, the engine is pulled down. When the machine torque is less than the propulsive torque limit, the engine is pulled up. The controller coordinates the pulled up engine with the machine such that the engine is subordinated to the machine.

A power supply system including: a driving motor capable of outputting power for driving a driving wheel; a main battery that stores electricity to be supplied to the driving motor; an engine capable of outputting power for driving the driving wheel; a starter motor that starts the engine; an auxiliary battery that stores electricity to be supplied to the starter motor and auxiliaries; a switch of capable of making or breaking an electric coupling between the auxiliary battery and the starter motor, and the auxiliaries and the main battery; and a control apparatus that diagnoses an abnormality in the auxiliary battery. The main battery is coupled to the auxiliaries via a DC-DC converter capable of stepping down a voltage of electricity stored in the main battery. The auxiliary battery is coupled to the auxiliaries via the switch. The controller diagnoses an abnormality in the auxiliary battery with the switch open.
