It is determined whether chargeable and dischargeable electric power of a battery which is a power storage device are limited. When it is determined that the chargeable and dischargeable electric power of the battery is limited, an electric power balance target value of the battery during gear shifting control in a stepped gear shifting unit which is a mechanical gear shifting mechanism is calculated. A smaller value is calculated as a change rate limit value when the chargeable and dischargeable electric power is small than when the chargeable and dischargeable electric power is great, and the calculated change rate limit value is used to perform gear shifting control in the stepped gear shifting unit.

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 vehicle system is provided and includes a modular dynamically allocated capacity storage system (MODACS) and an active management module. The MODACS includes blocks of cells. The active management module is configured to: detect a first state of a first block of cells of the blocks of cells; determine whether a safety fault condition exists with the first block of cells based on the first state of the first block of cells; in response to detecting existence of the safety fault condition, isolate the first block of cells from other ones of the blocks of cells; subsequent to isolating the first block of cells, actively discharge and detect a second state of the first block of cells; and based on the second state, continue isolating the first block of cells or reconnecting the first block of cells such that the first block of cells is no longer isolated.

A vehicle includes a traction battery, an electric machine, a relay electrically between the traction battery and electric machine, and a controller. When closed, the relay completes an electrical circuit including the traction battery and electric machine. The controller selectively commands the relay to open based on a voltage across a coil of the relay and a current through the coil.

The present disclosure discloses a vehicle and a coasting feedback control method for the same. The coasting feedback control method includes the following steps: detecting the current speed of a vehicle, the depth of a braking pedal of the vehicle, and the depth of an accelerator pedal; and when the current speed of the vehicle is greater than a preset speed, both the depth of the braking pedal and the depth of the accelerator pedal are 0, and the current gear of the vehicle is gear D, when the vehicle is not in a cruise control mode and an anti-lock braking system of the vehicle is in a non-working state, controlling the vehicle to enter a coasting feedback control mode, where when the vehicle is in the coasting feedback control mode, a coasting feedback torque of a first motor generator and a coasting feedback torque of a second motor generator are distributed according to a selected coasting feedback torque curve of the vehicle.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

The control device for a hybrid vehicle includes: a mechanical power source; an electric motor to be used when the mechanical power source is started; a first clutch arranged between the mechanical power source and a first transmission mechanism including a plurality of gear shift stages; a second clutch arranged between the mechanical power source and a second transmission mechanism including a plurality of gear shift stages; an electrical power source coupled to an input shaft of the first transmission mechanism; and a control unit for controlling a torque of at least one of the second clutch or the electric motor so as to compensate a braking force decreased upon a gear shift in the electrical power source when a gear shift request for shifting the gear shift stage of the first transmission mechanism is made during a regeneration travel of the electrical power source.

The present invention provides a shift control method implemented in a vehicle equipped with an automatic transmission for controlling an input shaft rotation speed to a target input shaft rotation speed during a shift. The method includes setting of a basic target synchronization rotation speed that is a basic target value of the input shaft rotation speed during the shift, and setting of a corrected target input shaft rotation speed as the target input shaft rotation speed when the shift is a downshift without a requirement for a driving force of the vehicle, The corrected target input shaft rotation speed is obtained by decreasingly correcting the basic target synchronization rotation speed. Further, a decreasing correction amount of the basic target synchronization rotation speed is set so as to become larger as a deceleration of the vehicle becomes larger.

When an output limitation value of a battery is equal to or less than a threshold, an electronic control unit determines that basic torque is able to be output from a second motor to a drive shaft. Then, the electronic control unit sets a predetermined value as a target motoring rotation speed for ending motoring of an engine by a first motor. When the output limitation value is greater than the threshold, the electronic control unit determines that the basic torque is unable to be output from the second motor to the drive shaft at the time of starting the engine, and sets a value smaller than the predetermined value as the target motoring rotation speed.
