AN EXPERIMENTAL STUDY ON DRIVER HANDLING PERFORMANCE UNDER ABNORMAL DRIVING CONDITIONS

An investigation was undertaken into the vehicle handling qualities of a driver in a vehicle subjected to side winds and in a vehicle suddenly confronted by an unexpected obstacle. These conditions were simulated on a test road by means of arbitrary and impulsive steering of the rear wheels of a four wheel steered vehicle. The investigation showed that the reaction speed of the driver by constant spectral disposition of the angle of yaw did not change. In contrast to that, driver reactions changed when the distribution functions changed; i.e. The drivers increased their steering movements in those cases where the maximum frequency component of the yaw angle was low, whilst they reduced the steering movements when the maximum frequency component was high. Experienced drivers generally reacted satisfactorily to ensure the stability of the vehicle by reducing steering movements. Immature drivers found it impossible to maintain their steering movements close to the yaw resonance point, when they were exposed to a considerable disturbance, which lay beyond their ability to control. There was then a tendency towards a hazardous situation. (TRRL)
