Abstract

A lane keep assist system for a vehicle includes a controller that receives first and second signals including values for a distance from a point on the vehicle to an edge of a lane marker for the vehicle's lane of travel at first and second times. The controller determines a rate of change in the distance responsive to the first and second signals and generates a power steering system control signal responsive to the rate of change. The control signal generates a force on a steering gear of the vehicle connected to one or more steerable wheels on the vehicle to control the position of the vehicle relative to the lane of travel with the amount of the force responsive to the rate of change.

Abstract

The invention relates to the ride height control of vehicle structures with air suspension. A compressor (12) functions as a pressure source, which supplies a pressure accumulator (40) with pressure, wherein the compressor (12) supplies a respective spring element (15,16) of a respective wheel suspension with pressure via a directional control valve (24) and a pressure supply line (23). Via a corresponding actuation of the directional control valve (24), the spring elements (15, 16) can be connected to a collection container or the atmosphere in order to lower the ride height. The lowering process is improved with constructive design. In addition, the air spring valves (26) of an axle (VA), where there is a higher pressure level, are connected to a first common supply line (25), and the air spring valves (26) of an axle (HA), where there is a lower pressure level, are connected to a second common supply line (27). The construction is also provided with a pressure adjusting device (30) between the separate supply lines (25, 27) for both axles (VA, HA) and the pressure supply line (23) from the pressure accumulator (40), which provide for pressure adjustment between the two axles (VA, HA) during the lowering of the ride height. Furthermore, a throttle valve (32) can also be used in the pressure adjusting device (30), which provides for a lowering of the pressure at the axle (HA), where there is a lower pressure level, in order to prevent a raising of the vehicle body at this axle (HA) via the overflowing of pressure medium from the other axle.

Abstract

A wear monitoring device of a disk brake includes a brake disk, a first brake lining on a first face of the brake disk, and a second brake lining on a second face of the brake disk, in particular for commercial vehicles. The wear monitoring device has a first sensor unit that quantitatively ascertains the cumulative wear of the first and second brake linings. The wear monitoring device outputs, at the output connection of the first sensor unit, a first electrical output signal that is associated with the cumulative wear. A signal line is connected on the one hand to the output connection of the first sensor unit and on the other hand to an evaluating unit. The signal line is arranged in such a manner that, when a predetermined first wear limit of the first or second brake lining is reached, the signal line comes into contact with a stop.

A first control chamber is connected via a first control piston to a control arrangement in the control valve. During an adjustment of the first control chamber via the service-brake control pressure, the spring-loaded brake pressure at the working output is a function of the service-brake control pressure or of the parking-brake control pressure. The first control piston is connected to a third control chamber, wherein the pressure in the first control chamber acts on the first control piston in one direction, and the pressure in the third control chamber acts on the first control piston in the opposite direction. The first control chamber is selectively connectable to the third control chamber via a switchable bypass valve.

The invention relates to a method for controlling a vehicle (1), particularly a utility vehicle (1), when travelling on a bend (K), the utility vehicle (1) comprising a roll stability control system (10) for determining the probability (W) of overturning, said method comprising at least the following steps: determining bend information (R, R2), the bend information characterising the shape of the bend (K) in the direction of travel (F) from a current position (P) of the vehicle (1); determining predicted lateral acceleration values (alat_pi) according to the bend information (R, R2), the predicted lateral acceleration values (alat_pi) respectively indicating a lateral acceleration (alat) expected to act on the vehicle (1) in future positions (Pi) further along the bend (K); and determining the probability (W) of overturning in the future positions (Pi) according to the predicted lateral acceleration values (alat_pi). According to the invention, a reduced deceleration request is output by the roll stability control system (10) when the predicted lateral acceleration values (alat_pi) at least partially fall short of a lateral acceleration threshold value (plat_th), the reduced deceleration request (zSoll_r) being lower than a current deceleration request (zSoll) requested by the roll stability control system (10) in the current position (P), and for the reduced deceleration request (zSoll_r), the predicted lateral acceleration values (alat_pi) still remain lower than the lateral acceleration threshold value (plat_th).

Abstract

The invention relates to a method for decelerating a trailer vehicle (4), wherein wheel brakes (9) on the trailer vehicle (4) are actuated pneumatically using trailer brake pressure (14) so that the tendency of a trailer vehicle without ABS brakes to skid or push against the vehicle in front in a vehicle combination (5) during a braking process can be counteracted using simple vehicle equipment. According to the invention a wheel module (18) on one or more wheels (7) of the trailer vehicle (4) measures acceleration values for the wheel (7) concerned, generates an information signal (21) on the basis of the measured acceleration values and transmits said information signal wirelessly. The measured acceleration values are analysed and monitored for a tendency to lock up and, on receipt of an information signal (21), an electronic brake control unit (34) adjusts the trailer brake pressure (14) on the basis of the information signal (21). The invention further relates to a wheel module (18) for performing the method and a vehicle combination (5) having a towing vehicle (2) and at least one trailer vehicle (4).
