Device and method for decelerating a vehicle having a front-loading device

A method for decelerating a vehicle (2) having a front axle and a front-loading device, the method comprising the following steps:

• determining a mass and a center of gravity of a received load by using a sensor generating sensor data,
• evaluating the sensor data and determining a maximum braking deceleration in forward travel from the sensor data for avoiding tilting of the vehicle (2) about the front axle (4), actuating a hydraulic or pneumatic brake system (12) equipped with an anti-lock brake system (ABS) configured to effect a delimitation or reduction of an effective brake pressure (pBr_R) in wheel brake cylinders (30a, 30b) of the front axle (4),
• identifying, based on a sensor signal of a sensor (70, 72) of the hydraulic or pneumatic brake system (12), an emergency braking situation when the sensor signal reaches or exceeds a predefined limit value, and,
• upon identifying the emergency braking situation, activating an emergency braking operation that cancels the delimitation or reduction of the effective brake pressure (pBr_R) in the wheel brake cylinders (30a, 30b) of the front axle (4);
• controlling the emergency braking operation such that, with the exception of an anti-lock brake control operation, a full brake pressure (pBr_S) is introduced in a controlled manner by way of a primary brake valve (16) into the wheel brake cylinders (30a, 30b) of the front axle (4).

A device (1) for decelerating a vehicle (2) having a front-loading device and a front axle, the device comprising:

• sensors (64, 66, 68) for measuring a mass and a center of gravity of a received load at the vehicle, wherein the sensors measure the mass and center of gravity of the load received at the vehicle and generate corresponding sensor data,
• an electronic evaluation and control unit (20, 62) that evaluates the generated sensor data and, based on the generated sensor data, determines a maximum brake deceleration (pBr_tilt) in forward travel that prevents tilting of the vehicle (2) about the front axle (4),
• a hydraulic or pneumatic brake system (12) that is actuated by the evaluation and control unit (20, 62) and that limits an effective brake pressure (pBr_R) in wheel brake cylinders (30a, 30b) of the front axle (4) based on the maximum brake deceleration determined by the control unit, the brake system including an anti-lock brake system (ABS), wherein at least one sensor (70, 72) of the brake system (12) generates an emergency signal in an emergency braking situation,
• wherein the electronic evaluation and control unit (20, 62) receives and identifies the emergency signal and activates and controls an emergency braking operation;
• wherein, in the emergency braking operation, the electronic evaluation and control unit cancels the limit on the effective brake pressure (pBr_R) in the wheel brake cylinders (30a, 30b) of the front axle (4) and,
• wherein, in the emergency braking operation, the electronic evaluation and control unit causes an introduction of a full brake pressure (pBr_S), with the exception of an anti-lock control operation, in a controlled manner by way of a primary brake valve (16) into the wheel brake cylinders (30a, 30b) of the front axle (4).
