    Description

    The Driver Commands subsystem implements the driver model that generates acceleration, braking, gear, and steering commands. The subsystem contains variants that interact with typical driver vehicle inputs, such as steering, accelerator, decelerator, and transmission commands. These variants include driver models suitable for both longitudinal and lateral reference tracking, gaming hardware, interactive canvas widgets, and pass-through or external signal inputs.

    Vehicle Command Mode Setting

    Implementation

    Longitudinal Driver

    Longitudinal Driver block — Longitudinal speed-tracking controller. Based on reference and feedback velocities, the block generates normalized acceleration and braking commands that can vary from 0 through 1. Use the block to model the dynamic response of a driver or to generate the commands necessary to track a longitudinal drive cycle.

    Note

    The Longitudinal Driver setting is the only configuration implemented in the Powertrain Blockset™ reference applications.

    Predictive Driver

    Predictive Driver (Vehicle Dynamics Blockset) block — Controller that generates normalized steering, acceleration, and braking commands to track longitudinal velocity and a lateral reference displacement. The normalized commands can vary between -1 to 1. The controller uses a single-track (bicycle) model for optimal single-point preview control.

    Predictive Stanley Driver

    Predictive Driver (Vehicle Dynamics Blockset) block — Controller that generates normalized steering, acceleration, and braking commands to track longitudinal velocity and a lateral reference displacement. For lateral control, implements the Stanley method.

    Open Loop

    Implements an open-loop system so that you can configure the reference application for constant or signal-based steering, acceleration, braking, and gear command input.

    Dashboard Widgets

    Implements dashboard widgets for accelerator and brake control.

    Game Wheel Hardware

    Implements a game wheel for 3D simulation. Requires Simulink® 3D Animation™.

    No Driver

    No driver implemented.
