摘要： The drive and braking arrangement for a motor vehicle comprises at least one electric motor (7) driving the vehicle dependently upon the position of an accelerator pedal (11), a selector (15) setting the direction of rotation of the electric motor (7) drive to forward or reverse and means (27) for detecting the vehicle's travelling speed. In order to control the braking force of a friction brake device (17) acting on at least one (9) of the vehicle's wheels there is a controlling element (23) which can be set to a braking position by an electronic control (25) if the accelerator pedal (11) is set to a driving position for longer than a predetermined period and at the same time the detected vehicle speed is zero and/or if the means (27) allocated to the control (25) detect an actual direction of movement of vehicle which is opposite to that set by the selector (15).

摘要： The drive system for a motor vehicle comprises an internal combustion engine (1) with at least one controlling element (29) affecting its power and/or torque and/or rotation speed, controllable by a motor element (27), an electric generator system (3) driven by the engine (1), at least one electric motor (11) powered by the generator system (3) and driving the motor vehicle and an electronic control (19) which controls at least the one motor element (27) and the electric power supplied by the generator system (3) and/or the electric power taken by the electric motor (11) depending on the position of an accelerator pedal (23). The system includes means for detecting the actual value of the rotation speed of the engine (1) and means for detecting an actual value of the power supplied by the generator system (3). The control (19) comprises rotation speed regulators (33), which maintain the actual rotation speed at a predetermined setting, and power regulators (37) which maintain the actual electric power at a predetermined setting. To the control (19) is allocated a data store (31) in which characteristic data for combinations of data for the power setting and data for the rotation speed setting and/or data for regulating the at least one motor element (27) are stored. Both with the generator arrangement (3) and with the engine (1) on overrun, depending on the current from the generator arrangement, the control (19) detects the torque cycle depending on the crankshaft angle and, depending on the rotation speed cycle, diagnoses operating faults and/or the state of the motor.

摘要： A motor vehicle contains a unit (2) consisting of an internal combustion engine and a generator which supplies current to electric motors (12, 16) coupled to the driving wheels (14, 18) via a power-distribution power electronics system (8). In addition there is an accumulator (22) into which power from the internal combustion engine-generator unit (2) is fed. An electronic control (20) controls the power distributor (8) depending on a running signal in accordance with boundary conditions, e.g. the lowest possible specific fuel consumption. A temporary high power requirement can be covered by the accumulator (22). During more sustained increased power consumption, the internal combustion engine, which is run when possible in a mode consuming little fuel, is speeded up to cover the increased power requirement. At the maximum power of the internal combustion engine, the power stored in the accumulator (22) can be used for additional thrust.

摘要： A drive system for a motor vehicle having at least one driven wheel (1, 7) on each side of the longidudinal axis of the vehicle comprises an internal combustion engine (13), an electric generator (11) driven by the internal combustion engine (13), an electric motor (9) for each driven wheel (1, 7) and an electronic control system (15, 19, 21) that controls the amount of electric power supplied by the generator (11) to the individual electric motors (9). The control system (15, 19, 21) controls the power and the distribution of the driving torques to the individual wheels (1, 7) so that the roll steer effect of the vehicle is controlled by conferring a yawing moment that depends for example on the transverse acceleration of the vehicle or on the extent of a yawing moment generated by a side wind. By measuring the wheel pressure of the individual driven wheels, the road grip limits of the wheels may be detected and the electric motors may be controlled in order to improve traction.

摘要： In order to detect a critical driving torque or an information representing the coefficient of friction at the road adhesion threshold for a vehicle having several driven wheels (5), at least two of the driven wheels (5) are associated to torque controlling means (13) that allow the ratio between the driving torques of both driven wheels (5) to be varied. Torque detecting means generate a torque signal that corresponds to the strength of at least the highest driving torque among those of both driven wheels (5). Wheel slip detecting means (19) that detect the increase in wheel slip of the wheel (5) with the highest driving torque beyond a predetermined slip threshold are associated to the driven wheels (5). The information on the coefficient of friction is generated depending on the strength of the detected driving torque of the wheel (5) whose slip exceeds the slip threshold. In order to determine the information on the coefficient of friction, the distribution of the driving torques of front axle (7) and rear axle (9) is periodically and alternatively increased.
