Abstract
A computer has a processor and a memory storing instructions executable by the processor to: in response to a vehicle decelerating to a standstill, activate automatic vehicle hold mode to maintain the vehicle at the standstill. While the vehicle is at the standstill in the automatic vehicle hold mode, the instructions include instructions to: deactivate the automatic vehicle hold mode in response to depression of a brake pedal to a position that maintains the vehicle at the standstill after deactivation of the automatic vehicle hold mode; and then, deliver creep torque to wheels of the vehicle in two-pedal drive mode when the brake pedal and an accelerator pedal are both in a released position.

A computer having a processor and a memory storing instructions executable by the processor to:
- in response to a vehicle decelerating to a standstill, activate automatic vehicle hold mode to maintain the vehicle at the standstill;
- and
- while the vehicle is at the standstill in the automatic vehicle hold mode:
- deactivate the automatic vehicle hold mode in response to depression of a brake pedal to a position that maintains the vehicle at the standstill after deactivation of the automatic vehicle hold mode;
- and
- then, deliver creep torque to wheels of the vehicle in two-pedal drive mode when the brake pedal and an accelerator pedal are both in a released position.
A method comprising:
- in response to a vehicle decelerating to a standstill, activating automatic vehicle hold mode to maintain the vehicle at the standstill;
- and
- while the vehicle is at the standstill in the automatic vehicle hold mode:
- deactivating the automatic vehicle hold mode in response to depression of a brake pedal to a position that maintains the vehicle at the standstill after deactivation of the automatic vehicle hold mode;
- and
- then, activate two-pedal mode in which creep torque is delivered to wheels of the vehicle when the brake pedal and an accelerator pedal are both in a released position.
