A protective helmet is described comprising: an outer layer (1); an inner layer (5) for contact with a head of a wearer; and an intermediate layer (3, 4) comprising an anisotropic cellular material comprising cells having cell walls, the anisotropic cellular material having a relatively low resistance against deformation resulting from tangential forces on the helmet. The anisotropic material can be a foam or honeycomb material. The foam is preferably a closed cell foam. The helmet allows tangential impacts to the helmet which cause less rotational acceleration or deceleration of the head of the wearer compared to helmets using isotropic foams while still absorbing a significant amount of rotational energy.

The invention concerns an automated motor vehicle shift transmission (1) with an input shaft, an output shaft and several selectively engaged gears, the input shaft (W1) being connected to a drive motor (M) via an engine clutch (K) that can be engaged and disengaged. To avoid an interruption of the traction force during a shift process, a controllable friction clutch is provided as a change-under-load clutch (K5) to connect the input shaft (W1) directly to the output shaft (W3, W4) when necessary.

The invention also concerns a method for controlling the gearshifts of an automated motor vehicle shift transmission comprising an input shaft, an output shaft and several selectively engaged gears, and in which the input shaft is connected to a drive motor via an engine clutch that can be engaged or disengaged, such that in a shift process between a loaded gear that is engaged and a target gear to be engaged, the engine clutch remains closed during the gear change. To avoid a traction force interruption it is provided that during a shift process between two gears containing at most one direct step (i>=1), before the loaded gear is disengaged a change-under-load clutch, positioned between the input shaft (W1) and the output shaft (W3, W4), is at least partially closed in order to take over the torque transfer, the loaded gear is then disengaged, the target gear is then synchronized and engaged, and finally the change-under-load clutch (K5) is fully opened again.

The starting system may reverse the operation of the generator so as to apply torque to the rotor during the shutdown procedures.

In a coasting control process, an ECU increases line pressure PL of a hydraulic path to predetermined pressure P1 such that discharge pressure of an MOP becomes higher than that before a C1 clutch is disengaged at timing when an executing condition of coasting control is satisfied (time t=t1). According to such coasting control process, driving torque of the MOP increases, so that deceleration (deceleration G) caused by driving of the MOP by a drive wheel becomes larger than that in conventional coasting control in which the discharge pressure of the MOP is not increased. As a result, it is possible to inhibit a driver from feeling discomfort due to free-running feeling generated during the coasting control.
