摘要:
A driver assist arrangement (1) is provided comprising a first yaw rate controller (7), a hazard evaluation unit (9) and a driver intention evaluation unit (13). The first yaw rate controller (7) is configured to control a yaw rate of the hosting vehicle (5), by comparing an expected yaw rate with an actual yaw rate and in response thereto selectively apply brakes of respective wheels of the host vehicle (5). The arrangement (1) further comprises a second yaw rate controller (15), configured to intervene in the control of the first yaw rate controller (7), in case the evaluated risk of an accident is above a threshold value and occurrence of an avoidance manoeuvre initiated by the driver (3) is detected. The present invention also relates to a vehicle (5) comprising a driver assist arrangement (1) and a method of assisting a driver (3) of a vehicle (5).

A method in controlling a steering assistance actuator in a steering system (100) of a vehicle and one or more controllable vehicle state actuators so that the steering-wheel torque applied by the driver is an indicative for the driver intention and transformed to a target yaw and/or lateral vehicle state to be controlled by one or more vehicle state controllers and actuated by the vehicle state actuators along with the fact that the level of understeer is used to achieve an additional steering-wheel torque in the form of a ramp in the steering-wheel torque as a function of the level of understeer.

A collision avoidance assistance device configured to perform driver steering assistance to avoid a collision between a vehicle and an obstacle, the device includes a steering control unit configured to perform the steering assistance in a case where it is determined that there is a possibility of the collision between the vehicle and the obstacle. During a period from commencement of the steering assistance to elapsing of a first time determined by response characteristics of a lateral acceleration of the vehicle, the steering control unit is configured to rotate a steering wheel of the vehicle in a collision avoidance direction by a control amount determined based on a steering holding force of the driver.

The invention relates to a drive stabilisation method 24, 24', a drive stabilisation device 1 and a related vehicle 2, which is particularly a commercial vehicle. For the stabilisation 56, 92 of the vehicle 2, a steering angle ßVA, ßZA of at least one steered front axle VA and/or additional axle ZA of the vehicle 2 is changed 40, 42, 84 by automatic forced steering of this axle VA, ZA. Additional drive stabilisation is achieved with a feature a) and additionally or alternatively with a feature b). According to feature a), in response to a tilting tendency of vehicle 2 recognised by means of a tilt-stability control device 6 as being above a tilt limit value GKipp in addition to the initiation of a vehicle delay 38 for the reduction of this tilting tendency, an adjustment 48, 50 of a changed steering angle ßVA, ßZA of the steered front axle VA and or additional axle ZA is initiated in order to counteract 54 an understeering or oversteering influence 52 of this vehicle delay 38 on the vehicle 2. According to feature b) the direction of movement BZA in the wheel contact point CZA of an additional axle wheel RZA arranged on the steered additional axle ZA is determined 68 relative to the vehicle longitudinal axis 4 and the steering angle ßZA of the steered additional axle ZA is adjusted 86 depending on this respectively determined direction of movement BZA in order to reduce the drift angle aZA of the additional axle wheel RZA relative to its direction of movement BZA.

A steering system for a vehicle (10) includes a front wheel (12, 14) supported for rotation about a first axis (34) and a pivot axis (36) transverse to the first axis (34) and spaced inboard of a centerline (40) of the front wheel (12, 14). The front wheel (12, 14) is movable about the pivot axis (36) to change direction of the vehicle (10). A brake (26) coupled to the front wheel (12, 14) provides braking rotation of the front wheel (12, 14) and a controller (28) controls operation of the brake (26) to generate a desired braking force in a direction determined to adjust a vehicle direction.
