    Abstract: The invention relates to a method for improving the drivability of a motor vehicle (100; 110) with a driveline. The method comprises the step of comparing a first signal (S3; S3*) with a second signal (S4), where the first signal (S3; S3*) contains information about a torque (TQ-max; TQ-maxmod ) which can be generated by an engine (230) of the vehicle (100; 110) at a prevailing speed (RPMmom ) of the engine (230), and the second signal (S4) contains information about a torque (TQ-req ) requested from the engine. The method comprises also the step of selecting an engagement speed (RPMin) of the engine (230) for an automated clutch (235) in the driveline of the vehicle (100; 110) on the basis of said comparison between the first signal (S3; S3*) and the second signal (S4). The invention relates also to a system for improving the drivability of a motor vehicle and a computer programme product comprising programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to a device and a motor vehicle equipped with the system.

    Abstract: Method and system for monitoring the lining clearance of a disc brake or drum brake (10) which is provided with one or more brake linings (11a, 11b) and which is applied by pneumatic or hydraulic brake pressure imparted by a brake cylinder (12). The relationship between the stroke of the brake cylinder, or of some portion of a brake mechanism (16), and the brake pressure of the brake cylinder, is determined at the time of a braking operation on the basis of measured values representing said stroke and measured values representing said brake pressure. The position where thebrake linings under the action of the brake cylinder come into initial contact with the brake disc or brake drum at the time of the respective braking operation is determined by analysis of the gradient of the relationship between said stroke and said brake pressure, after which a calculation value representing the prevailing lining clearance is determined on the basis of the difference between the measured value of said stroke registered in said determined position and a measured value of said stroke registered at a time when said brake pressure is nil.
