Claim 8:
9. A method of braking a vehicle comprising (1) one or more main brake assemblies, (2) one or more electronic parking brakes, (3) a plurality of wheels, and (4) a wheel speed sensor, by using (1) a main control unit controlling the one or more main brake assemblies, (2) a redundancy control unit controlling the one or more electronic parking brake, brakes, and (3) 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, the method comprising:
determining whether the main control unit malfunctions;
determining whether the redundancy control unit malfunctions;
in response to determining that the main control unit is not malfunctioning, controlling the main control unit to (1) perform a first slip control on the plurality of wheels based on a signal from the wheel speed sensor, (2) calculate the regenerative brake force, and (3) 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
in response to determining that the main control unit is malfunctioning and the redundancy control unit is not malfunctioning, controlling the redundancy control unit to (1) perform a second slip control on the plurality of wheels of the vehicle based on the from the wheel speed sensor, (2) calculate the regenerative brake force, and (3) generate and transmit, to the regenerative braking unit, the regeneration braking signal indicative of the regenerative brake force calculated by the redundancy control unit.
