Abstract
A transportation vehicle provides a brake autohold function to maintain braking without requiring the driver to continuously apply pressure on a brake pedal. The vehicle comprises an autohold selector, a parking brake selector, a brake pedal, and an accelerator pedal. A braking system is adapted to enter an autohold event according to a pressed brake pedal at vehicle standstill during an active autohold mode toggled by the autohold selector. A controller is configured to terminate the autohold event in response to either a deactivation command using the parking brake selector or accelerator pedal movement, without deactivating the autohold mode. By manually terminating the brake autohold event the vehicle can begin to creep forward using only the torque generated by the engine at idle, thereby avoiding the additional torque that is generated when the accelerator pedal is used to terminate the brake autohold event.
