A vehicle control device includes a controller configured to control operation of a braking device and operation of a driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. The controller is configured to execute braking control, including braking by the braking device and regenerative braking by the driving motor, during the cruise control mode in accordance with a change in a vehicle traveling condition. The braking control includes causing the braking device to generate a braking force without using the regenerative braking and subsequently executing a braking-force switching process including increasing a braking force by the regenerative braking while reducing the braking force from the braking device, if a determination result indicates that the vehicle speed is stable.

A torque control method and apparatus for a vehicle, including: determining whether a torque change request is received, during a process of performing an energy recovery function; determining whether an antilock brake system is in an active state, in case that the torque change request is not received; if so, decreasing an energy recovery torque with a first torque change gradient; determining whether the antilock brake system is transited from the activated state to a non-activated state, during a process of decreasing the energy recovery torque; if so, determining whether it is satisfied that a first current driver demand torque is greater than a first preset value and the antilock brake system is in the non-activated state for longer than a first preset time; and if satisfied, recovering the energy recovery torque to the first current driver demand torque with a second torque change gradient.

A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

A hybrid all-wheel-drive vehicle includes an engine, first and second motor generators, a first clutch between the second motor generator and a front wheel, a second clutch between the second motor generator and a rear wheel, and a control unit that controls, based on a vehicle traveling state, the engine, the motor generators, and the clutches. The first motor generator is coupled to the engine and the front wheel in a manner capable of transmitting torque. During regeneration, the control unit engages the first clutch and disengages the second clutch. When the all-wheel-drive vehicle shifts from motor traveling to hybrid traveling, the control unit restarts the engine by operating the first motor generator and regulates engagement forces of the clutches and output torque of the second motor generator to compensate driving torque of the front wheel by the second motor generator while maintaining driving torque of the rear wheel.

A control device performs braking using a regenerative brake based on power generation in a motor generator in motor-driven traveling and performs a battery protecting process of starting an engine to set up transmission of a driving force between the motor generator and the engine using a clutch and performing braking based on an engine brake when a state of charge of a battery is equal to or greater than a threshold value in the motor-driven traveling. The control device sets a fuel-cutoff-permission rotation speed to a second rotation speed lower than a first rotation speed when the engine is started through the battery protecting process.
