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.

A degradation determination device for a secondary battery is used for a hybrid vehicle, is configured to determine degradation of the secondary battery, and includes a processor. The processor is configured to determine whether predetermined charge control is executed based on a vehicle speed, an accelerator operation amount, and a fuel injection amount or a rotational speed. The processor determines that degradation of the secondary battery has progressed when a charge frequency is high compared to when the charge frequency is low. The charge frequency is the ratio of the time for which the predetermined charge control is executed to a required time for a predetermined period.

A method of controlling a sleep maintenance motion includes: determining, by a sleep maintenance mode entry determiner, whether a vehicle enters a sleep maintenance mode; when the vehicle enters the sleep maintenance mode, calculating, by an engine target speed profile calculator, an engine target speed profile; calculating, by an engine/hybrid starter generator (HSG) target torque calculator, an engine/HSG target torque based on the calculated engine target speed profile; and controlling, by the sleep maintenance mode entry determiner, a sleep maintenance motion based on an operation of an engine/HSG.

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.

Presented are hybrid electric vehicle (HEV) powertrains and control logic for optimized regenerative braking (regen), methods for making/using such systems, and HEVs with increased regen through reduced engine and transmission friction. A method of operating an HEV includes determining if an REV operating state or fault prevents engagement of a regen control operation and, if not, responsively determining if a torque request for the REV's powertrain is less than a road load on the HEV. The regen control operation is executed responsive to the torque request being less than the road load. The regen control operation includes the power transmission drivingly disconnecting the engine from the road wheels, and the engine operating at a target engine speed. A negative torque offset to maintain a vehicle deceleration rate after disconnecting the engine from the road wheels is calculated; the traction motor outputs a negative torque based on this negative torque offset.
