Abstract
An apparatus for the recognition of a rising slope is provided in particular for commercial vehicles, such as trucks or busses. The device comprises at least one sensor (1) for the axle load of the rear axle and/or of the front axle, as well as a device (4) for measuring the vehicle acceleration relative to the road. The signals of the sensor (1) and of the device (4) are fed into an electronics (2). The electronics (2) recognizes from these fed-in data, whether the vehicle is disposed on an uphill grade or on a downhill grade or on level ground. The thus generated signal can be further employed in various electronic systems, for example, in an automatic drawbar force control system.
