Abstract:
A front wheel and rear wheel interlocking brake system for a motorcycle in which a front wheel brake and a rear wheel brake, each being hydraulically operated, are provided on a front wheel and a rear wheel, respectively, said brake system comprising:a front wheel side actuator for applying a hydraulic pressure to said front wheel brake; a rear wheel side actuator for applying a hydraulic pressure to said rear wheel brake; a first and second brake operating means operated by a driver; an operated amount detecting means for detecting an operated amount of said brake operating means; and a control means for receiving and calculating an operated amount detected by said operated amount detecting means, and outputting drive control signals to said front wheel side actuator and said rear wheel side actuator on the basis of the calculated result, wherein said control means receives running state information other than said operated amount detected by said operated amount detecting means, and performs brake control for single brake control for singly driving either said front wheel brake or said rear, wheel brake and interlocking brake control for driving said front and rear wheel brakes in accordance with a specific braking force distribution characteristic, and causes control to switch between single brake control and interlocking brake control on the basis of said running state information, and wherein said control means also performs brake control in such a manner that when either of said first and second brake operating means is operated, said single brake control is performed until said detected operated amount reaches a specific value, and if said detected operated amount exceeds said specific value, said single brake control is switched into said interlocking brake control.
