A regenerative braking control method of a hybrid vehicle may include: a vehicle condition determination operation of determining, by a controller, whether a vehicle speed and a driving mode satisfy conditions suitable for regenerative braking control of the hybrid vehicle; an accumulated count increasing operation of increasing, by the controller, an accumulated count of a reduction direction signal when the reduction direction signal is input from a two-way input device while the conditions are satisfied; an accumulated count reducing operation of reducing, by the controller, the accumulated count of the reduction direction signal depending on a count of the increase direction signal when the increase direction signal is input from the two-way input device while the conditions are satisfied; and a phased braking operation of increasing, by the controller, regenerative braking torque of a motor in phases depending on the accumulated count of the reduction direction signal.

A system and a method of controlling an operation of an autonomous vehicle are provided. The method includes receiving, by the autonomous vehicle, information about neighboring vehicles and estimating a lane change intention of a first vehicle of the neighboring vehicles in a next lane in a front direction of the autonomous vehicle through the input information. Whether to allow the first vehicle to change a lane in consideration of acceleration/deceleration of the autonomous vehicle and whether a safe distance between the autonomous vehicle and the neighboring vehicles is secured is determined. An acceleration/deceleration control signal is generated for adjusting a traveling speed of the traveling vehicle and regenerative braking force and friction braking force of the autonomous vehicle is distributed according to the acceleration/deceleration control signal to perform braking.

The present disclosure provides an electronic stability control method for a vehicle for performing vehicular electronic stability control simply by adjusting driving force and braking power that are generated by a driving device of the vehicle without use of a driving force distributing method between front, rear, left, or right vehicle wheels. To this end, the vehicular electronic stability control method includes determining a vehicular state value indicating a driving state of a vehicle from information collected from the vehicle, comparing the determined vehicle state value with a first reference value, and controlling an operation of a driving device for generating driving force for driving the vehicle by the controller when the vehicle state value is greater than the first reference value to adjust driving force for preventing understeer or oversteer of the vehicle.

A hybrid vehicle using an engine driving a generator to supply power to electric drive motors through a system power bus, and a method for controlling power regeneration in a hybrid vehicle are disclosed. Ground drive controllers associated with the drive motors are configured to determine a slope of a surface on which the vehicle is driving and set a maximum downhill speed of the vehicle based thereon. A generator controller, in response to the drive motors generating power through regenerative braking, regulates power on the bus by directing the generated power to recharge the battery when the battery has capacity, reducing an output of the generator to the bus when the battery is fully charged, and driving a driveshaft to drive the engine with the generator to consume excess power on the bus when the generator output is reduced to zero.

A power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of a power source affixed to a trailer to capture energy from movement of an axle of the trailer, and a motor powered by the power source to operate and provide movement assistance to the axle.

A regenerative braking control method of a vehicle, may include a first operation of determining a driving risk of a road surface on the basis of a status of the road surface while driving; a second operation of determining whether an accelerator pedal is released while driving; a third operation of determining whether a brake pedal is operated while driving; and a fourth operation of performing no regenerative braking when the accelerator pedal is determined as being released, the driving risk of the road surface is determined as being high, and when the brake pedal is determined as not being operated.

A vehicle includes an accelerator pedal, a brake pedal, an electric machine, friction brakes, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle during regenerative braking. The friction brakes are configured to brake the vehicle. The controller is programmed to, responsive to an operator selection of a one-pedal drive mode, decrease vehicle speed via regenerative braking in response to releasing the accelerator pedal. The controller is further programmed to transition the vehicle to an inhibit state in which the friction brakes are applied to prevent vehicle creep in response to receiving an automated signal to disable the one-pedal drive mode and vehicle speed becoming zero while the one-pedal drive mode is selected.

A system for coupling a towing vehicle to a towed vehicle and/or for controlling charging/braking by the towed vehicle. The system may include a coupler coupling to the towing vehicle; and first and second tow bars having first and second ends and a rotational joint situated between the first and second ends, the first and second tow bars coupled to the coupler at the first ends and being non-parallel in at least one plane with the second ends located further apart from each other than the first ends. The rotational joint providing for the first and second tow bars to be positioned in an open and a folded position. The second ends of the first and second tow bars are configured to be coupled to the towed vehicle. For charging, a trip distance and charge of a towed vehicle battery is utilized to determine a charging rate for the trip.

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 power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of: a power creation module that generates electrical power, a battery which store the electrical power, a motor affixed to a trailer axle of a trailer which provides a turning force to the trailer axle when enabled to operate from the stored electrical power of the battery, and a motor controller configured to initiate the motor to operate according to a predefined sensor condition.
