Abstract: A vehicle includes at least one brake assembly configured to brake at least one wheel of the vehicle in response to an applied voltage. A power supply is in signal communication with the at least one brake assembly. The power supply is configured to operate in a first mode that outputs a first voltage and a second mode that outputs a second voltage greater than the first voltage. A brake control system is in signal communication with the at least one brake assembly and the power supply. The brake control system is configured to determine a driving state of the vehicle, and is configured to output a brake boost request signal to initiate the second mode of the power supply in response to detecting the driving state, wherein a braking response time of the at least one brake assembly is improved in response to applying the second voltage.

Abstract: A vehicle includes an engine, an accelerator pedal, transmission, transfer case, mode selection device, road wheels, an electronic brake assembly, and a controller. The transfer case is connected to the transmission, and is operable for establishing a predetermined transfer case mode. The mode selection device receives a requested crawl mode of the vehicle in the predetermined transfer case mode. The electronic brake assembly has a brake motor and brake calipers, with each brake caliper disposed proximate a respective wheel to brake the respective road wheel. The controller is programmed to simulate a four-wheel drive-low mode of the transfer case in response to the requested crawl mode by decelerating the vehicle via control of the brake assembly and limiting a gear state of the transmission to 1st or 2nd gear. An auto-hold state may be engaged in crawl mode when the vehicle stops to prevent rolling of the vehicle.
