  • Patent number: 11577702
    Abstract: A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.

  • Patent number: 11544858
    Abstract: Methods and systems implemented in a vehicle involve obtaining a single camera image from a camera arranged on the vehicle. The image indicates a heading angle ?0 between a vehicle heading x and a tangent line that is tangential to road curvature of a road on which the vehicle is traveling and also indicates a perpendicular distance y0 from a center of the vehicle to the tangent line. An exemplary method includes obtaining two or more inputs from two or more vehicle sensors, and estimating kinematic states of the vehicle based on applying a Kalman filter to the single camera image and the two or more inputs to solve kinematic equations. The kinematic states include roll angle and pitch angle of the vehicle.

  • Patent number: 11505245
    Abstract: A steer-by-wire steering system for a motor vehicle with a steerable front wheel axle that has two steerable wheels. The front wheel axle includes a single wheel drive which, by means of a drive controller, individually drives wheel drives which are associated with the steerable wheels. The drive controller has a controller which determines a target speed for the left-hand wheel and a target speed for the right-hand wheel in accordance with an accelerator pedal angle and a rotational angle of a steering shaft, and which limits the target speeds to a slip-limited speed. The drive controller individually drives the wheel drives in such a way that the difference between the target speed and the actual speed for each steerable wheel is minimal.
