An electrified vehicle includes a human-machine interface to enable a towed vehicle mode to enable electric pumps to lubricate and/or cool vehicle components and to disable driver assistance features while the electrified vehicle is being towed by another vehicle. The electrified vehicle includes a drivetrain having an electric machine configured to provide propulsive torque to vehicle wheels, a high-voltage traction battery selectively connected to the electric machine, a battery powered fluid pump configured to pump fluid to the drivetrain, and a controller programmed to, after receiving a signal enabling towed vehicle operation of the electrified vehicle, control operation of the battery powered fluid pump while the electrified vehicle is being towed. The controller may disable one or more driver assistance features and alerts such as automatic emergency braking, automatic shifting of the drivetrain, automatic parking brake operation, automatic headlights, automatic steering, cruise control, parking assistance, and external object distance detection.

Towed electrified vehicle control

An electrified vehicle includes an electric machine, a traction battery selectively connected to the electric machine, a human-machine interface (HMI), and a controller programmed to, after receiving a signal from the HMI enabling towed vehicle operation of the electrified vehicle, control the electric machine to generate a regenerative braking torque in response to deceleration of the electrified vehicle exceeding an associated deceleration threshold and road grade being below a road grade threshold. The controller may also be programmed to control friction brakes of the electrified vehicle in response to the deceleration exceeding the associated threshold. The controller may control brake lights of the electrified vehicle in response to the regenerative braking and/or friction braking. Regenerative and friction braking may be released in response to acceleration exceeding a corresponding threshold.
