<p>PURPOSE:To improve the braking operation feeling by selectively outputting a braking current target value corresponding to the operation amount of brake operating means from a multiplexer. CONSTITUTION:When a brake pedal 7 is operated at a braking time, brake data correspoding to operation amount from a decoder 8 is supplied to a controller 6. The controller 6 selects brake current data corresponding to the brake operating data read out at this time from the brake current data prepared in advance in a ROM61, and supplies through photocouplers 9A-9C to a multiplexer 10. The multiplexer 10 outputs the brake current target value in response to the brake current data. A comparator 11 outputs a deviation signal between the brake current target value and the brake current, and the controller 6 controls the conduction ratio of a chopper thyristor 2 in response to the deviation signal.</p> |
