摘要:
A vehicle driving force control apparatus controls a control torque command of an electric motor (4) based on a power supplying condition of an electric power source (7). The power source (7) supplies electric power to the electric motor (4) that drives at least one wheel (3L or 3R) of the vehicle. An electric power supplying status detecting section (8J) determines an electric power supplying capacity of the electric power source (7) based on the power supplying condition of the power source (7), while an electric motor torque control section (8C) controls the control torque command of the electric motor (4) based on the power supplying condition determined by the electric power supplying status detecting section (8J). Preferably, an internal combustion engine (2) that drives at least one other wheel (1L or 1R) also drives a generator (7) that acts as the power source of the electric motor (4). The vehicle driving force control apparatus is especially useful in a four-wheel drive vehicle.
摘要:
A driving force control apparatus is provided to optimize the acceleration performance and improve the energy efficiency of a vehicle. Preferably, the front wheels (1R, 1L) are driven by the internal combustion engine (2), while the rear wheels (3R, 3L) are driven by the electric motor (4). The electric motor (4) is driven by electrical power generated by the generator (7). The generator (7) is driven by the engine (2). When acceleration slippage occurs in the front wheels (1R, 1L), the generator (7) is controlled so as to produce a generation load torque corresponding to the acceleration slippage magnitude.

To suppress occurrence of a wheelie of a motorcycle. A torque control apparatus includes a the detection unit that detects a state in which the front wheel of the motorcycle is likely to be lifted up based on at least one of engine information of the motorcycle, accelerator operation information of the driver of the motorcycle, and information of the vehicle body or wheel of the motorcycle. The torque control apparatus further includes an output unit that, when the detection unit detects the state in which the front wheel is likely to be lifted up, outputs a torque smaller than a request torque of the driver as a request torque for an the engine of the motorcycle or outputs the difference between the request torque of the driver and a torque smaller than the request torque of the driver as a brake torque.
摘要:
A vehicle (10) includes a set of motors (21, 23, 25, 27) for driving ground engaging elements (20, 22, 24, 26), for example wheels, and a controller (60) for controlling the traction of the ground engaging elements. The disclosed system and method for controlling traction on a work vehicle utilize front differential speed, rear differential speed, and fore-aft differential speed.

A traction control device includes: rotation speed detectors (43FL to 43CR) provided to wheels; a control-start determiner (82) that determines whether or not to control a braking mechanism and a differential adjusting mechanism based on rotation speeds; a braking mechanism controller (84) that controls the braking mechanism based on a result of the determination of the control-start determiner (82); and a differential adjusting mechanism controller (85) that controls the differential adjusting mechanism based on the result of the determination of the control-start determiner (82), in which the control-start determiner (82) includes: a right-left-wheel rotation speed difference calculating section (822); a front-rear-wheel rotation speed difference calculating section (823); and a control-start determining section (825) that determines whether or not to start controlling at least one of the braking mechanism and the differential adjusting mechanism when one of rotation speed differences reaches or exceeds a predetermined threshold.
