Claim 0:
1. An electrohydraulic brake system for a vehicle comprising a plurality of wheels and a wheel speed sensor, the plurality of wheels divided into (1) a first wheel group having one or more front wheels of the vehicle and (2) a second wheel group having one or more rear wheels of the vehicle, the electrohydraulic brake system comprising:
one or more main brake assemblies configured to generate a first braking force for the wheels of the first and second wheel groups;
one or more electronic parking brakes configured to generate a second braking force for the wheels of one of the first and second wheel groups;
a main control unit configured to control the one or more main brake assemblies;
a redundancy control unit configured to, in response to detecting that a malfunction has occurs to a braking function of the main control unit, control the one or more electronic parking brakes based on a signal from the wheel speed sensor to perform a slip control on the vehicle; and
a regenerative braking unit configured to generate, based on a regeneration braking signal generated by the main control unit or the redundancy control unit, a regenerative brake force required for braking of the vehicle,
wherein, in response to detecting no malfunction of the brake function of the main control unit, the main control unit is configured to calculate the regenerative brake force and generate and transmit, to the regenerative braking unit, the regeneration braking signal indicative of the regenerative brake force calculated by the main control unit, and
wherein, in response to detecting the malfunction of the brake function of the main control unit, the redundancy control unit is configured to calculate the regenerative brake force and generate and transmit, to the regenerative braking unit, the regeneration braking signal indicative of the regenerative brake force calculated by the redundancy control unit.
