摘要： A vehicle driving apparatus includes: an engine; a first rotary electric machine; first and second output shafts; a power distribution device for distributing a power between the first and second output shafts; and a control device for controlling an electric-power generation torque of a second rotary electric machine such that a power distribution ratio between the first and second output shafts becomes a target distribution ratio, and controlling a total torque of the engine and the first rotary electric machine such that a requested drive torque is obtained. The control device executes an electric-power consuming control to supply at least a part of a generated electric power generated by the second rotary electric machine, to the first rotary electric machine without via a power storage device, and to drive the first rotary electric machine, such that an operation state of the engine is brought close to a fuel-economy optimum state.

摘要： A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected at least one of driving modes. The driving modes include a low-gear all-wheel driving mode and a high-gear all-wheel driving mode. In a case in which the low-gear all-wheel driving mode is selected in the high-gear all-wheel driving mode when the engine is in a stopped state with a vehicle power transmission apparatus being in a non-driving position that disables transmission of a drive power, the engine control portion maintains the stopped state of the engine until completion of switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode, and starts the engine after the completion of the switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode.

摘要： A control apparatus for an all-wheel drive vehicle that includes (i) a power source, (ii) a power distribution device for distributing a power from the power source to front and rear wheels, (iii) a differential limiting mechanism for placing the power distribution device in a differential limiting state in which a rotational difference between the front wheels and the rear wheels is limited, and (iv) a braking device for applying a wheel braking torque to each of the front and rear wheels. When the power distribution device is placed in the differential limiting state and the wheel braking torque is applied to each of the front wheels and the rear wheels, a torque limiting control is executed for setting an upper limit value of a torque of the power source to a smaller value when the wheel braking torque is large than when the wheel braking torque is small.

摘要： A control system includes one or more processing circuits comprising one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to acquire speed data regarding current speeds of tractive elements of the vehicle from tractive element speed sensors of the vehicle, determine speed references for the tractive elements to perform autonomous driving operations where the speed references indicate speeds at which each of the tractive elements should rotate to accommodate the autonomous driving operations, and control at least one of a driveline or a brake system of the vehicle to selectively alter the current speeds of the tractive elements of the vehicle based on the current speeds and the speed references to accommodate the autonomous driving operations.

摘要： Aspects of the present invention relate to a control system for controlling torque distribution between a first axle (110) and a second axle (120) in a vehicle (100), the control system comprising one or more controllers. The control system is configured to detect that the vehicle is in overrun and detect the vehicle speed. When the vehicle is in overrun and the vehicle speed is below a first speed threshold then the torque distribution is controlled to reduce overrun torque to the first axle and to increase overrun torque to the second axle. The vehicle may be a hybrid vehicle comprising an internal combustion engine (ICE) (201), a belt integrated starter generator (B-ISG) (205) and an electric rear axle drive (ERAD) (204).

摘要： A vehicle driving apparatus includes: an engine; a fluid transmission device; first and second rotary electric machines; an output shaft for receiving a power transmitted through a first power transmission path and outputting the power to one of a pair of front wheels and a pair of rear wheels; and a control device for controlling an engine operation point by adjusting an electrical path amount between the first and second rotary electric machines. The second rotary electric machine outputs the power to the other of the pair of front wheels and the pair of rear wheels, through a second power transmission path. The control device obtains a target electrical path amount enabling the engine operation point to become a target operation point, and causes a speed change device provided in the second power transmission path to establish a gear ratio enabling the target electrical path amount to be attainable.

摘要： A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.

摘要： An off-road vehicle includes a driveline, a control system, and a braking system. The driveline provides driveline power and driveline brake power to a first tractive assembly and/or a second tractive assembly. The control system stores vehicle information, determines driving instructions based on environment data, and determines speed references for tractive elements of the first and second tractive assemblies based on the driving instructions and the vehicle information. The braking system includes brakes and a braking subsystem. The brake subsystem operates the brakes to provide brake power to one or more components of the first and/or second tractive assemblies. The brake controller controls the brakes to selectively provide the brake power and the control system controls the driveline to selectively provide the driveline power and the driveline brake power based on current speeds of the tractive elements and the speed references to accommodate the driving instructions.
