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.

Provided is a braking control device configured to apply auxiliary braking force only as needed, for example, when a travel path of a vehicle includes a curve such as a blind corner, and configured to apply the auxiliary braking force without causing a driver of the vehicle to feel uneasy about operation. The braking control device calculates target braking force based on reference braking force and input braking force information (a driver-input braking force converted value), calculates, based on the target braking force, the auxiliary braking force for reducing uneasiness (performing a process to reduce uneasiness) felt by the driver about the braking operation, and then calculates final target braking force by using the auxiliary braking force (by adding the auxiliary braking force to the driver-input braking force converted value).
