Claim 16:
17. A vehicle comprising:
a human-machine interface unit configured to generate a tow mode activation signal; and
a drive unit including:
an electric motor;
an encoder configured to generate motor speed information of the electric motor; and
an inverter configured to control operation of the electric motor; and
a controller including a processor having computer-readable media configured to store computer-executable instructions configured to cause the processor to:
receive the generated tow mode activation signal from the human-machine interface unit;
activate a hold mode in response to the received tow mode activation signal;
generate a zero-speed command in response to the hold mode being activated;
send the generated zero-speed command to the inverter;
compare the generated zero-speed command to a threshold value; and
deactivate the hold mode in response to the generated zero-speed command being greater than the threshold value such that the processor ceases to generate the zero-speed command until the free-wheel tow mode is deselected by a user.
