PCT No. PCT/EP91/02030 Sec. 371 Date Sep. 30, 1993 Sec. 102(e) Date Sep. 30, 1993 PCT Filed Oct. 26, 1991 PCT Pub. No. WO92/09464 PCT Pub. Date Jun. 11, 1992.A hydraulic antilock brake system is described, with a multi-way valve hydraulically switched to connect the brake pressure generator (1) to the wheel brake (2), controlling, in response to the pump pressure prevailing in the auxiliary pressure conduit (4), the pressure fluid connection between the brake pressure generator (1) and the wheel brake (2). The valve (3) is switched by pump pressure in the absence of pressure from the brake pressure generator, but held or switched open if the brake pressure generator is operated. This allows a low-cost adaption to traction slip control with no need for additional electronic controls while substantially preserving the basic circuit configuration, especially the electronic control system. |
