Abstract An antilock brake system with separate front- and rear-wheel safety means, in which front-wheel antilock control means and rear-wheel antilock control means are made so operative independently of each other that, when the front-wheel antilock control means for a front wheel generally having a larger proportion of the brake force distributed is troubled in its brake force suppressing state, front-wheel saftey means makes the function of the front-wheel antilock control means wholly ineffective to ensure the brake force to the front wheel whereas, when the rear-wheel antilock control means for a rear wheel generally having a smaller proportion of the brake force distributed is troubled in a state having lost its brake force suppressing function, rear-wheel safety means operates to effect that the brake force to the rear wheel is always stronger than that to the front-wheel thereby to maintain the steering stability of the wheeled vehicle.
An antilock brake system with separate front- and rear-wheel safety means, comprising: a brake force applying system for applying a brake force to front and rear wheels; front-wheel antilock control means for suppressing the brake force applied to said front wheel when the brake force to said front wheel is excessively strong; rear-wheel antilock control means for suppressing the brake force applied to said rear wheel when the brake force to said rear wheel is excessively strong; front-wheel safety means for detecting a malfunction, when said front-wheel antilock control means is malfunctioning in its brake force suppressing state, to instantly block the supply of power to said front-wheel antilock control means; and rear-wheel safety means for suppressing the brake force to said rear wheel each time the brake force to said rear wheel is excessively strong, when said rear-wheel antilock control means has a malfunction and has lost its brake force suppressing function.

An antilock brake system with separate front- and rear-wheel safety means, comprising: a brake force applying system for applying a brake force to front and rear wheels; front-wheel antilock control means for suppressing the brake force applied to said front wheel when the brake force to said front wheel is excessively strong; rear-wheel antilock control means for suppressing the brake force applied to said rear wheel when the brake force to said rear wheel is excessively strong; front-wheel safety means for detecting a malfunction, when said front-wheel antilock control means is malfunctioning in its brake force suppressing state, to instantly block the supply of power to said front-wheel antilock control means; and rear-wheel safety means for suppressing the brake force to said rear wheel each time the brake force to said rear wheel is excessively strong, when said rear-wheel antilock control means has a malfunction and has lost its brake force suppressing function.
Claim 3
Dependent Claim
40 words
An antilock brake system as set forth in claim 1, wherein said rear-wheel safety means suppresses the brake force to said rear wheel only for a predetermined time each time the brake force to said rear wheel is excessively strong.
Claim 4
Dependent Claim
