1. A vehicle interface system of a vehicle, comprising:
- a user input device for receiving a passenger braking request from a passenger, the user input device distinct from each of a brake pedal and an accelerator pedal fixedly installed in a vehicle cabin;
a transducer coupled to the user input device for generating an output based on the braking request; and
a controller with software logic for,receiving the transducer output;
generating each of an engine brake torque command and a wheel brake torque output command based on the passenger braking request, the engine brake torque command including an engine compression braking and an engine regenerative braking command, the engine brake torque command generated independent of an operator braking request received via the brake pedal and an operator acceleration request received via the accelerator pedal, wherein the operator braking request and the operator acceleration request is received along with the passenger braking request, and wherein the generating includes overriding the operator braking request and the operator acceleration request; and
relaying the engine brake torque command and the wheel brake torque output command to a vehicle control system via a vehicle diagnostics port, the port also relaying diagnostic codes related to vehicle malfunction.

Abstract
A driver training vehicle system includes a driver training vehicle and an interface system with an auxiliary control unit that is removably installable in the vehicle. A vehicle control system can receive a brake input from a vehicle driver via a floor pedal in the vehicle as well as a brake input from a vehicle passenger via the auxiliary unit. The control system adjusts an engine torque and a brake torque based on the received brake inputs to decelerate the vehicle.

9. A driver training vehicle system, comprising:
-
a cabin of a vehicle; a powertrain system including an engine and a transmission; a brake system including wheel brakes for braking vehicle wheels; a brake pedal for receiving a brake request from a vehicle operator, the brake pedal mechanically coupled to the brake system; an accelerator system including an accelerator pedal for receiving an acceleration request from the vehicle operator, the accelerator pedal coupled to the powertrain system; a diagnostics port inside the vehicle cabin, the diagnostics port configured to receive a brake request from a vehicle passenger via an auxiliary unit removably couplable to the diagnostics port, the auxiliary unit not mechanically coupled to the brake system; and a control system with computer readable instructions for, generating a first set of commands responsive to the vehicle operator brake request or the vehicle operator acceleration request and adjusting a wheel brake torque based on the first set of commands; and upon receiving the vehicle passenger brake request via the diagnostics port along with the vehicle operator brake request or acceleration request, generating a second, different set of commands based on the passenger brake request; overriding the first set of commands; and based on the second set of commands, increasing engine compression braking, increasing engine regenerative braking, and adjusting engine operation to decrease an engine power, and increase an engine braking torque. - View Dependent Claims (10, 11, 12, 13, 14)

15. A driver assistance interface system, comprising:
-
a vehicle including a first floor pedal fixedly installed in a cabin in a driver area, the first floor pedal mechanically coupled to a brake system; an auxiliary unit including a second floor pedal removably installed in the cabin in a passenger area, the second floor pedal electronically coupled to the brake system and a powertrain system of the vehicle; and a control system with computer readable instructions for, receiving a first acceleration input from a vehicle driver via the first pedal while receiving a second deceleration input from a vehicle passenger via the second pedal; and responsive to the second deceleration input, overriding the first acceleration input by increasing a wheel brake torque, an engine brake torque, engine compression braking, and engine regenerative braking to decelerate the vehicle. - View Dependent Claims (16, 17)
