A vehicle having a front trunk and a method of controlling a vehicle to access the trunk may include raising a hood from a closed position adjacent body structure to a fully open position with the hood oriented horizontally to provide access to a front trunk, raising a grille with the hood; and pivoting the grille about a hinge affixed to the hood. Front trunk lighting and bins maybe included in the vehicle.

A hydraulic lock for a hydraulic system includes a flow control valve and a second check valve. The flow control valve having a first inlet, a first outlet, a first check valve and a flow restrictor, each of the first check valve and the flow restrictor being communicably coupled to the first inlet and the first outlet and being arranged in parallel between the first inlet and the first outlet. The second check valve having a second inlet and a second outlet, the second inlet being communicably coupled to the first outlet, the second check valve further having a ball seating surface having an aperture there through, a ball, and a resilient member biasing the ball towards the ball seating surface to seal the aperture, the aperture being communicably coupled to the second inlet and the second outlet.

To reduce or prevent erroneous recognition by a user concerning the roof operation of a convertible vehicle whose roof is adapted to be opened and closed. A roof opening/closing system of a convertible vehicle includes an opening/closing device for opening/closing the roof of the convertible vehicle; and a controller for determining, with respect to at least one of the opening and closing operations by the opening/closing device, whether to enable or disable the operation; and a notifying device for notifying a user whether the operation is enabled or disabled as determined by the controller. For example, in the case where the burning protection is turned off, following the determination based on the condition relevant to burning protection lift of prohibition of the roof operation is notified when other permitting conditions for the roof operation are fulfilled.

A hydraulic drive for a sash of a door, a gate, a window or the like comprises a housing and a piston which is displaceably guided in the housing and which divides the interior of the housing into a pressure chamber and a non-pressurized chamber. In this case, the drive, which can in particular be a hydraulic door closer, comprises a regulating valve which is arranged on the end face of the housing delimiting the pressure chamber on the side facing away from the piston and which is integrated in particular in a housing cover for activating an impact function. The regulating valve has a valve member which is displaceable between a closed position and an open position in a valve bore of a valve housing formed in particular by the housing cover, is impinged on in the closing direction by the pressure in the pressure chamber and can be transferred into the open position thereof by the spring force of a spring unit when the pressure in the pressure chamber falls below a predeterminable limit pressure.
