A method for controlling a brake system in an agricultural work vehicle, wherein the work vehicle comprises a drive train having a drive engine, an adjustable ratio transmission, which is arranged downstream of the drive engine and via which a driving power generated by the internal combustion engine can be transmitted to the drive axle, a service brake device and at least one auxiliary brake device.

To provide a drive control device of a moving body capable of increasing a regeneration amount without hindering a driver's brake operation and causing too much deceleration. A drive control device of a moving body that updates a regenerative pattern of a driving motor of the moving body including a brake that generates a braking force by being linked to an operation amount of a brake pedal, the drive control device including an external world information acquisition unit that acquires external world information and a brake detector that detects ON/OFF of the brake, wherein when the brake detector detects ON, the regenerative pattern is changed based on the external world information acquired by the external world information acquisition unit such that a braking distance only decreases.

A vehicle brake system and a method of control. A friction brake torque and a secondary brake torque may be applied with a friction and secondary brakes, respectively, under various operating conditions, such as when a brake torque command is less than a threshold brake torque command.

A control device for a vehicle deceleration device of a vehicle including an electronics unit, with the aid of which a time curve of an input variable predefined by a driver of the vehicle with the aid of an actuation of the brake actuating element is evaluatable and the vehicle deceleration device is activatable taking into account the updated input variable and a characteristic curve, which specifies a relationship between the input variable and a setpoint variable with respect to a setpoint vehicle deceleration to be exerted on the vehicle with the aid of the vehicle deceleration device. The electronics unit detects at least one modulation and/or variation of the input variable triggered by the driver and reestablishes at least one subsection of the characteristic curve taking into account the at least one modulation and/or variation of the input variable (x.sub.input) triggered by the driver.

A hydrostatic traction drive in a closed hydraulic circuit includes two hydraulic machines in the closed hydraulic circuit and a control unit configured to control a braking torque of the traction drive. A method for controlling the hydrostatic traction drive includes controlling the braking torque for the hydrostatic traction drive.

A method for controlling a brake system in a vehicle includes providing a first non-friction braking torque for an axle of the vehicle when the vehicle has a first load. A second non-friction braking torque lower than the first non-friction braking torque is provided for the axle when the vehicle has a second load lower than the first load. Non-friction braking at the axle is limited by the first and second non-friction braking torques when the vehicle has the first and second loads, respectively.

A method adjusts a brake pedal characteristic of a vehicle having a brake pedal configured to generate a brake pedal deceleration demand and at least one further deceleration demand generating device to generate at least one further deceleration demand. The vehicle is configured to decelerate according to the brake pedal deceleration demand and to the at least one further deceleration demand. The method determines an achievable deceleration potential as a result of the further deceleration demand; generates a deceleration demand for adjusting the brake pedal deceleration demand at 0% brake pedal input according to the achievable deceleration potential; and adjusts the brake pedal characteristic of the vehicle.

A method for controlling a vehicle deceleration in a vehicle with an ABS brake system. The method includes detecting a target vehicle deceleration specified by a driver; defining a maximum deceleration and a minimum deceleration, each depending on the detected target vehicle deceleration; detecting an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a first vehicle axle and a second vehicle axle depending on the detected actual vehicle deceleration by actuation of ABS brake valves. Controlling the braking pressure by the actuation of the ABS brake valves comprises controlling the braking pressure on the wheel brakes of the second vehicle axle depending on a detected actual differential slip if the actual vehicle deceleration is less than the maximum deceleration and greater than the minimum deceleration, wherein the actual differential slip indicates the difference in a rotational behavior of the first vehicle axle.

A method for controlling a vehicle deceleration depending on a differential slip between two vehicle axles in a vehicle with an ABS brake system includes detecting at least one of a target vehicle deceleration specified by the driver and an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a vehicle axle to be controlled by actuation of ABS brake valves in such a way that the braking pressure on the wheel brakes of the vehicle axle to be controlled is controlled depending on a detected actual differential slip, so that the actual differential slip corresponds to a target differential slip. The actual differential slip indicates a difference in a rotational behavior of the vehicle axle to be controlled relative to a further vehicle axle. The target differential slip is dependent on at least one of the detected actual vehicle deceleration and the detected target vehicle deceleration.

An outdoor grounds maintenance vehicle is self-propelled by a hydrostatic traction drive system that provides dynamic braking to the vehicle without the need for separate service brakes acting on the wheels of the vehicle. An engine kill device can be manually actuated by the operator to access the dynamic braking of the traction drive system by reducing the speed of the prime mover that powers the pump of the traction drive system. This provides an auxiliary braking system that can be used in an emergency or on demand by the operator in the event the accelerator pedal does not properly control the pump swashplates. The operator can control the rate at which the auxiliary brake system reduces the speed of the prime mover to zero.
