Steering control device for a vehicle and method for operating said device
First Claim
1. A steering control device for reducing a turning radius of a vehicle having a steering actuator, a pair of steerable wheels, and a steering transmitting device connecting the steering actuator and the steerable wheels, and a vehicle brake control system, with the steering control device comprising a sensor arranged to detect the position of the steering actuator and to generate a steering position signal indicative of said position, with said vehicle brake control system receiving said steering position signal and braking the inside wheel when the steering position signal indicates that the steering actuator is approaching a maximum limit position.

Abstract
The invention relates to a steering control device for a vehicle, comprising a steering actuator, a pair of steerable wheels (1a, 1b) attached to the same wheel axle, a steering transmitting device connecting the steering actuator and the steerable wheels(1a, 1b), and a sensor (5) arranged to detect at least one parameter relating to a condition of the steering actuator and generate a signal indicative of said condition, which signal also categorizes each of the steerable wheels (1a, 1b) as an inside and an outside wheel respectively. The control device further comprises an electronic control unit (10) for a vehicle brake control system, which system is arranged to brake the inside wheel when a signal from the sensor (5) exceeds a predetermined value for a particular condition, in order to reduce the turning radius (R1, R2) of the vehicle. A method for operating the control system is also disclosed.
