摘要： A hybrid vehicle includes a controller. First control is control of an engine and a motor such that the hybrid vehicle travels by switching between a charge depleting mode and a charge sustaining mode. Second control is control of the engine and the motor such that the hybrid vehicle travels in accordance with a travel plan in which the charge depleting mode or the charge sustaining mode is assigned to each travel section of a travel plan route to a destination. The controller controls the engine and the motor such that a state of charge of an electric power storage device becomes higher in the charge sustaining mode in the second control than in the charge sustaining mode in the first control.

摘要： Each of a first clutch and a second clutch is, for example, an electromagnetic clutch that is operated by an electromagnetic actuator, and is supplied with electric power from the same in-vehicle battery as a starter motor of an engine. An electronic control unit is configured to not change a drive mode during a stop of the engine, and, after a predetermined period has elapsed from a start of operation of the starter motor at a startup of the engine (for example, the startup has completed) and a battery voltage has been recovered, change the drive mode to any one of a two-wheel drive mode and a four-wheel drive mode with the first clutch and the second clutch.

摘要： In a control device for four-wheel drive vehicle, yaw moment for suppressing understeer tendency of the vehicle is calculated as target yaw moment. If the average wheel speed of right and left wheels of a front shaft is more than the wheel speed of a turning outer wheel of a rear shaft, a control unit performs control as follows: when the target yaw moment Mzt is applied to the vehicle, a wheel clutch of the turning outer wheel is engaged, and a wheel clutch of a turning inner wheel is disengaged, so that the engaging force of a transfer clutch 15 is controlled based on the target yaw moment Mzt. If the average wheel speed of the right and left wheels is not more than the wheel speed of the turning outer wheel, the transfer clutch 15, right wheel clutch and left wheel clutch are disengaged.

摘要： A drive force control portion (90B) firstly changes a front wheel command torque (Tfcm) and a rear wheel command torque (Trcm) so that each command torque reaches a torque in a predetermined range. For example, if the rear wheel command torque (Trcm) reaches the torque in the predetermined range earlier than the front wheel command torque (Tfcm), the drive force control portion (90B) restricts the change of the rear wheel command torque (Trcm) (holds the rear wheel command torque Trcm constant) until the front wheel command torque (Tfcm) reaches the torque in the predetermined range. The drive force control portion (90B) releases the restriction on the change of the rear wheel command torque (Trcm) after the front wheel command torque (Tfcm) and the rear wheel command torque (Trcm) have entered the predetermined range. Therefore, it becomes possible to improve the vehicle stability in a vehicle that includes a plurality of power sources that drives a plurality of wheels.

摘要： A detection unit directly detects an operating force acting on a wheel. A computation unit respectively computes a current value of a regenerative braking force and a current value of a friction braking force based on the result of a detection by the detection unit. A setting unit sets a target value of the regenerative braking force and a target value of the friction braking force based on a required braking force. A control unit controls a regenerative braking device based on the current value of the regenerative braking force so that the regenerative braking force approaches to the target value and also controls a friction braking device based on the current value of the friction braking force so that the friction braking force approaches to the target value.

摘要： A road situation is estimated. If in a slipping state (a wheel slip flag F_SLIPnull1) or if an output changing switch is turned on by the driver of a hybrid vehicle, a second motor is energized based on a 4WD-oriented rear motor drive power map to avoid the slip. At the same time, a first motor is driven to generate electric power based on a 4WD-mode front motor charging map, thereby energizing the second motor.

摘要： A method for preventing damage to a driving system in vehicles may include determining whether a 4-wheel drive vehicle turns based on a steering angle signal, determining, based on an accelerator opening rate signal of the vehicle, whether a maximum torque causing damage to front wheel driveshafts is produced, checking a bump stroke amount of the vehicle and determining whether the front wheel driveshafts are likely to be damaged by a maximum torque transferred to the front wheel driveshafts when the vehicle turns, and lowering, when the front wheel driveshafts are likely to be damaged, a maximum torque of a 4-wheel drive torque applied to the front wheel driveshafts.
