A VEHICLE STEERING SYSTEM AND A METHOD FOR CONTROLLING A STEERING ANGLE OF A VEHICLE WHEEL

The invention relates to a vehicle steering system (10), comprising a steering wheel (12), a first and a second steering assembly (20A, 20B). The steering assemblies (20A, 20B) each comprise a steering linkage (22A, 22B) mechanically connected to a road wheel (4) and a support motor (24A, 24). The s...

More Information
Summary:The invention relates to a vehicle steering system (10), comprising a steering wheel (12), a first and a second steering assembly (20A, 20B). The steering assemblies (20A, 20B) each comprise a steering linkage (22A, 22B) mechanically connected to a road wheel (4) and a support motor (24A, 24). The steering wheel (12) is configured to control a steering angle of a first road wheel via a first support motor (24a) actuating a first steering linkage (22A). A processing circuitry (50) is configured to receive from the first steering assembly (20A) input signals (34A) comprising one or more steering parameter values measured for the first steering assembly (20A). Based on the received first input signals (34A), the processing circuitry (50) is configured to calculate a desired steering angle of a second road wheel (4) and to send control signals (52) to a second support motor (24B) so as to actuate a second steering linkage (20B) such that said desired steering angle of the second road wheel (4) is obtained. A method is also disclosed.
