## Abstract

A vehicle includes an engine, motor, powertrain, and controller. The engine and the motor are each configured generate power within the powertrain. The controller is programmed to, in response to full depression of accelerator and brake pedals while the vehicle is stopped and the powertrain is in drive, increase engine power to a maximum power output capacity and increase a motor torque to a predetermined torque output that is less than a maximum torque capacity.

## Claims

an engine and a motor each configured generate power within a vehicle powertrain; and
a controller programmed to, in response to full depression of accelerator and brake pedals while the vehicle is stopped and the powertrain is in drive, increase engine power to a maximum power output capacity and increase a motor torque to a predetermined torque output that is less than a maximum torque capacity.

### Claim 2 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to, in response to release of the brake pedal while full depression of the accelerator pedal is maintained, increase motor torque from the predetermined torque output to the maximum torque capacity.

### Claim 3 (depends on 2)

The vehicle of claim 2, wherein the controller is further programmed to, in response to release of the brake pedal while full depression of the accelerator pedal is maintained, increase an engine torque to a maximum torque output capacity of the engine.

### Claim 4 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to, in response to a predetermined time period elapsing while the accelerator and brake pedals are fully depressed and the vehicle is stopped, decrease engine power to an idle value and decrease motor torque to zero.

### Claim 5 (depends on 1)

The vehicle of claim 1 further comprising a traction battery and a generator, wherein the generator is configured to charge the battery, the engine rotates the generator to charge the battery while the vehicle is stopped, and the controller is further programmed to, in response to the battery obtaining a full charge while the accelerator and brake pedals are fully depressed and the vehicle is stopped, decrease the engine power to an idle value and decrease the motor torque to zero.

### Claim 6 (depends on 1)

The vehicle of claim 1 further comprising a traction battery and a generator, wherein the generator is configured to charge the battery, the engine rotates the generator to charge the battery while the vehicle is stopped, and the controller is further programmed to, in response to the battery exceeding a temperature threshold while the accelerator and brake pedals are fully depressed and the vehicle is stopped, decrease the engine power to an idle value and decrease the motor torque to zero.

### Claim 7 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to, in response to release of the accelerator pedal while full depression of the brake pedal is maintained, decrease the engine power to an idle value and decrease the motor torque to zero.

### Claim 8 (depends on 1)

### Claim 9

A vehicle comprising:
an engine and a motor each configured deliver power to a drive wheel; and
a controller programmed to, in response to full depression of accelerator and brake pedals while the vehicle is stopped, increase engine power to at least half of a maximum power capacity, increase a motor torque to a predetermined torque output that is less than a maximum torque capacity, and isolate the drive wheel from engine and motor power.

### Claim 10 (depends on 9)

The vehicle of claim 9, wherein the controller is further programmed to, in response to release of the brake pedal while full depression of the accelerator pedal is maintained, increase motor torque from the predetermined torque output to a maximum torque capacity of the motor and transfer the motor torque to the drive wheel.
