Abstract: A vehicle having an electronic parking brake system is provided. The vehicle includes a braking system having a first rotor and a first caliper. An electric motor is coupled to operate the first caliper. At least one sensor coupled to the vehicle to determine a braking characteristic. A controller electrically is coupled to the electric motor and the at least one sensor, the controller transmitting a first signal to the electric motor in response to receiving a second signal from the at least one sensor and determining that the braking system is performing below a predetermined level, the electric motor actuating the first caliper to apply a clamping force on the first rotor in response to the first signal.

Abstract: A vehicle includes a chassis, a power system supported by the chassis, and a plurality of wheels supported by the chassis. At least one of the plurality of wheels is operatively connected to the power system. A plurality of brakes is operatively associated with corresponding ones of the plurality of wheels, and a simulated brake pedal is operatively associated with the plurality of brakes. The simulated brake pedal is hydraulically isolated from the plurality of brakes. A non-hydraulic braking feedback controller is operatively connected to the plurality of brakes and the simulated brake pedal. The non-hydraulic braking feedback controller selectively provides at least one of a tactile, an audible, and a visual feedback to a driver based on an activation of the simulated brake pedal.
