<p>PURPOSE:To allow a driver to correctly change control modes even under a blind operation by combining identifications of audible sounds at an electric operation device for a car. CONSTITUTION:An operation unit (switch) 1 for generating the first operation signal to mutually switch two types of control modes is provided. Internal conditions in a condition memory means (D-FF circuit) 5 are changed in accordance with the operation signal from this operation unit 1. Electric oscillations preset for individual internal conditions are generated by electric oscillation generating means (one-shot multivibrators) 6a, 6b in response to a change of internal conditions of this condition memory means 5 whenever a change occurrs, and the electric oscillations are applied to a buzzer 10 to generate audible sounds, thus allowing a driver to correctly change the control modes.</p> |
