A controller changes a coast regeneration torque subject to regenerative braking by the driving motor when the vehicle is coasting, based on a difference between a driving wheel speed and a non-driving wheel speed, correction temperature determined based on the external temperature and the battery temperature, a friction coefficient of a road, and an operation condition of the ABS.

A method for controlling regenerative braking of a vehicle is provided, in which a driving area of a motor is decided when shifting gears during regenerative braking, and an amount of regenerative braking is determined based on the decided result. The method includes a first process of deciding whether motor torque is in a constant power mode, a second process of deciding whether the motor torque is in a constant torque mode, and a third process of deciding whether the mode of the motor torque is converted into the constant torque mode from the constant power mode.

A control method and apparatus of a vehicle including a drive motor are provided. The control apparatus includes a data detector that detects data to operate the vehicle and a controller that determines whether a braking condition is satisfied based on the data. The controller calculates a total braking amount and a regenerative braking allowance when the braking condition is satisfied and determines whether a shifting condition is satisfied when the braking condition is satisfied. A first actuator receives a control signal from the controller to adjust a hydraulic pressure supplied to each frictional element of the transmission and a second actuator receives the control signal from the controller to adjust the hydraulic pressure supplied to the wheel cylinder. An inverter receives the control signal from the controller to determine a switching operation of a switching element.

A vehicle electronic stability control system allows a vehicle to have improved movement performance and limit performance without causing a driver to feel uncomfortable, by actuating electronic stability control from a state where a lateral slip is relatively less likely to occur. The system prevents skidding of a vehicle including motors which individually drive a pair of left and right drive wheels. A stability determination module obtains information indicating vehicle behavior from a sensor, and determines whether or not the vehicle is in an unstable or less stable state, on the basis of the information. A braking/driving force control module which, when the stability determination module determines that the vehicle is in the unstable or less stable state, applies a braking force to one of the drive wheels, and simultaneously applies a driving force to the motor for the other drive wheel.

Systems and methods for operating a transmission of a hybrid powertrain that includes a motor/generator are described. The systems and methods may adjust one or more actuators in response to an estimated transmission input shaft speed that is determined from transmission output shaft speed. The one or more actuators may include a transmission clutch, the motor/generator, or a gear selection solenoid.

A system and method for controlling a transmission gear shift during a braking event in a vehicle having an electric motor and friction brakes both operable to brake the vehicle includes the step of reducing friction braking to increase wheel torque during the braking event. The braking event includes both friction braking and regenerative braking The reduction in friction braking to increase the wheel torque is based at least in part on a reduction in the wheel torque resulting from a change in gear ratio of a step-ratio transmission during the transmission gear shift.

A control apparatus applied to a hybrid vehicle of the invention executes a regeneration control for charging a battery with electricity generated by a motor generator while applying regeneration braking force to the vehicle from the motor generator. The apparatus executes an enlarged regeneration control for charging the battery with the electricity generated by the motor generator while applying increased regeneration braking force to the vehicle from the motor generator when a target deceleration end position is set.
