Embodiment Construction

[0029] figure 1 A steering control system 100 suitable for use in a commercial vehicle is shown, including a braking system 20 . The braking system 20 is configured to asymmetrically brake side wheels of the vehicle 10 based on a steering demand to steer the vehicle 10 based on a yaw moment generated. The steering control system includes a sensor unit 110 and a control module 120 . The sensor unit 110 is configured to be able to detect a braking request or deceleration of the vehicle and / or to detect a lateral deviation of the vehicle. The sensor unit 120 generates a corresponding braking indication signal 115 and / or steering demand indicating the amount of braking and / or steering required to correct the vehicle's position or offset. The control module 120 is configured to receive a brake indication signal and / or a steering request 115 . The control module 120 is further configured to generate the steering signal 112 (only) if the braking indication signal 115 indicates a b...

Abstract

A steering control system (100) for a commercial vehicle (10) is disclosed. The commercial vehicle (10) comprises a braking system (20) configured to brake dissymetrically side wheels of the vehicle (10). The steering control system (100) comprises: a sensor unit (110) and a control module (120). The sensor unit (110) is configured to detect a braking request or a deceleration of the vehicle and / or to detect a lateral offset and, based thereon, to generate a brake indication signal (115) and / or the steering demand, and the control module (120) is configured to receive the brake indication signal and / or the steering demand (115). If the steering demand is below a predetermined threshold value, the control module (120) is further configured to generate the steering signal only if the brake indication signal indicates a braking request. On the other hand, if the steering demand exceeds the predetermined threshold value, the control module is configured to generate the steering signal evenif the brake indication signal indicates no braking request. Finally, the control module (120) is configured to provide the steering signal (112) to the braking system (20) to brake the vehicle (10)dissymetrically and to thereby steer the vehicle.

Description

technical field [0001] The present invention relates to a steering control system and a method for controlling steering, in particular to 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...
