Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
101 words
An automotive energy management system comprising in combination: a housing, a first hydraulic unit having a first input/output member, a first reaction member, a first inlet port and a first outlet port, a second hydraulic unit having a second input/output member, a second reaction member which is coupled to said housing for obtaining therefrom an external reaction to torque developed in said second hydraulic unit, a second inlet port and a second outlet port, clutch means for selectively coupling said first reaction member to said second input/output member, and, brake means for selectively anchoring said first reaction member to said housing.
Claim 2
Dependent Claim
101 words
