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.

A platform for use with a temporary or auxiliary brake in a vehicle. An upper portion of the platform has a raised wall and stabilization flanges. The temporary or auxiliary brake is mounted on the raised wall. The raised wall is spaced from a floorboard of the vehicle. The stabilization flanges engage the floorboard to stabilize the upper portion. An extension plate, joined with a specialized and flexible weld, extends from the upper portion to provide increased stabilization of the platform and maintain the platform and the temporary or auxiliary brake in position on the floorboard of the vehicle, allowing the platform to fit virtually any year, make, or model of vehicle. The use of the platform and the temporary or auxiliary brake does not require drilling or deformation of the vehicle.

A steering brake locking system for a vehicle, such as an agricultural tractor, has at least first and second adjacent steering brake pedals, and a locking pin arranged to selectively lock the pedals together. The locking pin and at least a portion of the first and second pedals are formed from a conductive material, such that an electrically conductive path is formed between the first and second pedals through the locking pin when the pin is used to lock the pedals together. The locking status of the pedals can be determined by measuring the electrical conductivity between the first and second pedals.
