    • Embodiments of the present invention provide a motor vehicle having: prime mover means; at least first and second groups of one or more wheels; and a driveline operable by means of control means to connect a torque transmission path from the prime mover means to the first and second groups of one or more wheels such that the first group of one or more wheels and not the second group is coupled to the torque transmission path when the driveline is in a first mode of operation and both the first and second groups of one or more wheels are coupled to the torque transmission path when the driveline is in a second mode of operation, the driveline being operable to connect the second group to the torque transmission path by means of an auxiliary portion comprising first and second releasable torque transmitting means and a prop shaft, the first releasable torque transmitting means being operable to connect a first end of the prop shaft to the torque transmission path, the second releasable torque transmitting means being operable to connect a second end of the prop shaft to the second group of one or more wheels, the control means being operable to control the auxiliary portion to switch the driveline between the first and second modes of operation such that in the first mode the prop shaft is disconnected from both the torque transmission path and said second group of one or more wheels, the driveline being operable to transition from the first mode to the second mode responsive to a value of at least one vehicle operating parameter, when a transition to the second mode is made the vehicle being operable not to transition back to the first mode from the second mode before a disconnect delay period has expired.
    • 本发明的实施例提供一种具有:原动机装置的机动车辆; 至少第一组和第二组一个或多个轮; 以及传动系,其可通过控制装置操作,以将来自原动机装置的扭矩传递路径连接到一个或多个车轮的第一和第二组,使得第一组一个或多个车轮而不是第二组联接到 当传动系处于第一操作模式时,当传动系处于第二操作模式时,一个或多个车轮的第一组和第二组都联接到转矩传递路径上,扭矩传递路径可操作以将 第二组通过包括第一和第二可释放扭矩传递装置和传动轴的辅助部分到扭矩传递路径,第一可释放扭矩传递装置可操作以将传动轴的第一端连接到转矩传递路径, 第二可释放扭矩传递装置可操作以将支柱轴的第二端连接到第二组一个或多个车轮,控制装置b 可操作地控制辅助部分以在第一和第二操作模式之间切换传动系,使得在第一模式中,支轴与扭矩传递路径和所述第二组一个或多个车轮分离,所述传动系可操作 响应于至少一个车辆操作参数的值,从第一模式转换到第二模式,当进行到第二模式的转变使得车辆在断开之前不能从第二模式转换回到第一模式 延迟期已过。
