Принадлежит: Individual

The present disclosure relates to a hybrid working vehicle which determines the change of load by using a displacement of a flyweight or flyball in a governor, and controls a motor-generator according to the change of load, and a control method thereof. The hybrid working vehicle detects the change of load based on the displacement of the flyweight or flyball measured by a displacement measuring device, operates a motor-generator as a motor to supplement the power in a case where the load increases, and operates the motor-generator as an electric generator to collect energy in a case where the load decreases. In this way, revolution per minute (RPM) of a diesel engine may be detected rapidly and accurately based on the displacement of the flyweight or flyball without installing any complicated apparatus such as a torque measuring device which measures torque of a load, and accordingly controls the motor-generator so as to enhance the energy efficiency of the hybrid working vehicle and to improve the comfortable feeling of a driver.

Improved methods of controlling the stability of a vehicle are provided via the cooperative operation of vehicle stability control systems such as an Active Yaw Control system, Antilock Braking System, and Traction Control System. These methods use recognition of road surface information including the road friction coefficient (mu), wheel slippage, and yaw deviations. The methods then modify the settings of the active damping system and/or the distribution of drive torque, as necessary, to increase/reduce damping in the suspension and shift torque application at the wheels, thus preventing a significant shift of load in the vehicle and/or improving vehicle drivability and comfort. The adjustments of the active damping system or torque distribution temporarily override any characteristics that were pre-selected by the driver.

A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.

Precise operation of an accelerator operating member ( 7 ) is more difficult to perform in a reversing operation of a vehicle ( 1 ) as compared with an advancing operation. Therefore, behavior of the vehicle ( 1 ) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle ( 1 ), driving force output from an internal combustion engine ( 2 ) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle ( 1 ) in conformity to the actual operation of the accelerator operating member ( 7 ) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle ( 1 ). At this time, the vehicle ( 1 ) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle ( 1 ) from being unnatural.

Method for operating a motor vehicle and motor vehicle

Принадлежит: Audi AG

A motor vehicle can have multiple drive modes, for example rear wheel drive, four wheel drive, front wheel drive. Here, an active chassis device is used to make different adjustments, for example with respect to the toe-in angle and the camber angle, of a wheel or else with respect to wheel loads as a function of the drive load. As a result, the driving behaviour can be matched in each case in an optimum way to the drive mode, or conversely can be configured in such a way that changing the drive mode does not have a perceptible effect for the driver.

To avoid excess current being supplied to the motor, the upper limit of motor speed, which is the input speed of a second clutch, is set to a value less than a slip detectable limit value at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed) is set to a value equal to or greater than the slip detectable limit value so that the required driving force can be achieved by the gradient load corresponding driving force control.
