Abstract
A vehicle includes a powertrain having a powerplant and a transmission. The transmission has an input shaft operably coupled to the powerplant and an output shaft operably coupled to driven wheels. A vehicle controller is programmed to, in response to a brake pedal being applied, a speed of the output shaft being less than a threshold speed, and a position of an accelerator pedal being less than a threshold position, automatically engage friction brakes regardless of road grade and continue engagement of the friction brakes despite subsequent release of the brake pedal such that the friction brakes are engaged to hold the vehicle stationary independent of the road grade. The controller is further programmed to release the friction brakes in response to a position of the accelerator pedal being greater than a second threshold position.
