Influence of Tool Steer During Driving on Uneven Straight Roads for Heavy Trucks
Published September 21, 1992 by Verlag Des Verein Deutscher Ingenieure GmbH in Germany
Using an air-spring, two axle truck of 18.5t gross weight, the paper discusses open and closed loop maneuvers when driven over a 20cm high ramp with the left wheels, and with the steering wheel fixed, or with correction applied. The effect of the vehicle's response to specific driver inputs such as abrupt steering movements, frequency, braking in constant radius etc., is shown, and compared with the recommended limit values for lateral acceleration and yaw rate on this type of vehicle
