Embodiment Construction

[0026] figure 1 A steering control system 100 suitable for use in a commercial vehicle is shown, comprising a braking system 20 and a steering system 30 . The braking system 20 is capable of asymmetrically braking the side wheels of the vehicle, and the steering system is capable of steering the vehicle by turning the wheels in response to a turn signal. The steering control system 100 includes a selection module 110 and a control module 120 . The control module 120 is configured to be able to generate a first steering signal 111 indicative of a steering requirement in a first steering mode and capable of generating a second steering signal 112 indicative of a steering requirement in a second steering mode. The selection module 110 is configured to be switchable between a first steering mode that steers the vehicle by turning the wheels in response to a first steering signal 111 and a second steering mode. In a second steering mode, vehicle steering is achieved by generating...

Abstract

The present invention discloses a steering control system (100) for a commercial vehicle (10). The commercial vehicle (10) comprises a braking system (20) and a steering system (30), the braking system (20) is configured to brake dissymetrically side wheels of the vehicle (10), the steering system is configured to steer the vehicle (10) in response to a steering signal (112, 113).The steering control system (100) comprises: a selection module (110) and a control module (120). The selection module is configured to switch between a first steering mode and a second steering mode, wherein the first steering mode indicates a steering of the vehicle (10) by turning vehicle wheels and the second steering mode indicates a steering of the vehicle (10) by generating a braking signal for at least onevehicle wheel resulting in a yaw moment applied to the vehicle (10). The control module (120) is configured to generate the first steering signal (111) indicating a steering demand in the first steering mode and a second steering signal (112) indicating a steering demand in the second steering mode. The control module (120) is further configured to provide the first steering signal(111)to the steering system (30) and the second steering signal (112) to the braking system (20) to brake the vehicle (10) dissymetrically and thereby steer the vehicle (10) as a result of the yaw moment.

Description

technical field [0001] The present invention relates to a steering control system and a method for controlling steering, especially a system for controlling lateral movement of a vehicle using a Steer-by-Brake process. Background technique [0002] Vehicles today are equipped with many assistance features to support the driver in various situations. For example, the traffic jam assist function helps the driver maintain a safe distance from the vehicle ahead while following the lane. Such a traffic jam assist function is only implemented in conventional systems during low-speed operation, for example in stop-start situations. However, in these conditions the vehicle has to brake frequently, leading to increased wear on the brake linings. Furthermore, autonomous lane following is difficult in conventional systems, especially for commercial vehicles, because the autonomous actuation of the steering system is technically very complex. [0003] Therefore, there is a need for a...
