Abstract
A line lock braking system includes a brake module configured to selectively apply hydraulic braking pressure against first wheels and second wheels of the vehicle, and a controller in signal communication with the brake module. The controller initiates, upon receipt of a request, a vehicle line lock mode and performs line lock braking of the vehicle where the brake module is controlled to selectively apply braking pressure against the first wheels and not the second wheels such that the second wheels are free to rotate based on a throttle applied by a driver; completes the line lock mode upon release of a button being depressed to enter and maintain activation of the line lock mode such that the braking pressure against the first wheels is released; and cancels the line lock mode upon determining a number of rotations of the second wheels exceeds a predetermined number of wheel rotations.
