A vehicular breaking force control system includes: a plurality of actuators capable of generating a braking force for a vehicle; a coasting state detection unit configured to detect that a coasting state has been established; a target braking force calculation unit configured to calculate a target braking force on the basis of a state of the vehicle when the coasting state detection unit detects that the coasting state has been established; and a braking force distribution control unit configured to determine a distribution braking force that is a braking force to be caused to be generated by each actuator, such that the distribution braking force is equal to or less than a braking force generable by the actuator and a sum of the distribution braking forces is equal to the target braking force, and to perform control of causing each actuator to generate the distribution braking force.

There is provided a hybrid vehicle that suppresses overdischarge of a power storage device. In the case where a braking force is applied to drive wheels accompanied with regenerative driving of a second motor in an accelerator-off state upon satisfaction of a filter regeneration condition, when a state of charge of a power storage device is equal to or higher than a reference value, an engine and a first motor are controlled such as to perform fuel cutting of the engine and motoring of the engine by the first motor. When the state of charge of the power storage device is lower than the reference value, on the other hand, the engine is controlled such as to perform self-sustained operation or rotation stop of the engine.

Provided herein are systems and methods for allocating power distribution in hybrid vehicle drivetrains. An engine instrumentation unit can acquire engine measurements on a hybrid drivetrain of a vehicle. The engine measurements can include a fuel use measurement of a combustion engine and a battery use measurement of an electric motor. A vehicle control unit can maintain a power distribution profile. Each power distribution profile can define a power allocation to the combustion engine and a power allocation to the electric motor specified for engine measurements as associated with an environmental condition. The vehicle control unit can compare the engine measurements. The vehicle control unit can select a power distribution profile based on the comparison. The vehicle control unit can set a power splitter to transfer of the mechanical power from the combustion engine and the electric motor to a differential unit in accordance with the power distribution profile.

A system for emissions mitigation for a hybrid automobile vehicle includes an automobile vehicle provided with motive power from: a battery pack; an engine; and a controller in communication with the battery pack and the engine. A threshold battery pack state-of-charge (SOC) is predetermined. A minimum battery pack SOC is less than the threshold battery pack SOC. An engine-on charge depletion (EOCD) command is issued by the controller to start the engine in an engine-catalyst light-off operation condition when the vehicle is operating using power from the battery pack and when the threshold battery pack state-of-charge (SOC) is reached to mitigate against exceeding vehicle emissions standards.

A powertrain for a vehicle may include a vehicle chassis, a rotatable vehicle drive axle, at least one selectively movable electric propulsion motor having a rotatable motor shaft rotatable about an axis defined by the rotatable vehicle drive axle, a motor actuator connected to the at least one selectively movable electric propulsion motor, and a control system in communication with the motor actuator. The control system may include a memory device in communication with the control system having instructions that when executed by the control system causes the control system to receive at least one input from at least one sensor and instruct the motor actuator to rotate the at least one selectively movable electric propulsion motor based on the at least one input from the sensor.

Methods and systems are provided for controlling thermal conditioning of a battery system associated with brakes of a vehicle towing a trailer. In one embodiment, a method includes: determining, by a processor, that a temperature of the battery system is outside of a defined temperature range; determining, by the processor, a delta value between a brake request and a battery charge limit; generating, by the processor, a control signal to at least one of a heater and a compressor of the vehicle based on the delta value; generating, by the processor, a control signal to the battery system to initiate regeneration braking; and generating, by the processor, a braking reduction request to reduce braking by the trailer.

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 truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, 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.

A method collectively and yet individually assesses a parking area and locates a parking space which is energy-optimized with respect to a temperature control. A correspondingly equipped parking system carries out the method.

A control system for hybrid vehicles to prevent a reduction in a brake force when an electrical input to a battery is restricted. A controller is configured to execute a regeneration control to deliver a regenerative torque resulting from operating second motor as a generator to the drive wheels, and an engine brake control to deliver a brake torque resulting from a power loss of an engine to the output member. The controller is further configured to select an HV-Lo mode when an input power allowed to accumulate in the battery is smaller than a threshold power.

A motor control device includes an acquisition unit and a torque control unit that controls, by selectively using one of a first map and a second map, a motor torque defined in correspondence with a requested torque and an engine rotation speed in each of the first map and the second map. The torque control unit controls the motor torque using the first map when the battery temperature is less than a switch temperature lower than a limit start temperature at which the motor torque is limited, and controls the motor torque using the second map when the battery temperature is greater than or equal to the switch temperature and less than the limit start temperature. The second map includes a larger assist region than the first map. The assist region of the second map defines a smaller maximum torque than the assist region of the first map.
