Vehicle Control

The user wants to develop, implement and test a function for longitudinal and/or lateral vehicle control based on environmental data provided by VTD.

01
MiL
Model in the Loop
Workflow

VTD provides vehicle dynamics, traffic and sensor models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to a software model that computes the reaction of the car to the actual situation.

Use Cases

ADAS and active safety systems (emergency braking, cruise control etc.)

Benefits

VTD provides a scalable solution for deterministic real-time and non real-time testing early-on in the development of a control system.

02
MiL-v
Model in the Loop (Variant)
Workflow

VTD provides the sensor and traffic models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to a software model that computes the reaction of the car to the actual situation. The vehicle dynamics is executed on the user’s side and the resulting position is sent back to VTD.

SiL
Software in the Loop
Workflow

VTD provides vehicle dynamics, traffic and sensor models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to the actual software that computes the reaction of the car to the actual situation.

04
HiL
Hardware in the Loop
Workflow

VTD provides traffic and sensor models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to the actual ECU hardware using custom protocols. The vehicle dynamics is executed in the real-time HiL system and the resulting position is sent back to VTD.

Use Cases

ADAS and active safety systems (emergency braking, cruise control etc.)

Benefits

VTD operates in co-simulation mode with real-time performance. The HiL implementation is used in later stages of a system’s development cycle.

05
DiL
Driver in the Loop
Workflow

VTD provides traffic, sensor and vehicle dynamics models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to the vehicle control system. The human driver has his own perception of the environment (via monitors or projection systems). The controller blends and prioritizes human vs. controller commands and sends the result back to the vehicle dynamics on VTD side.

Use Cases

ADAS and active safety systems (emergency braking, cruise control etc.)

Benefits

VTD operates with real-time performance and high-quality graphics.

06
ViL
Vehicle in the Loop
Workflow

VTD provides traffic and sensor models. The sensors filter the environment for relevant static and dynamic objects and provide object lists to the vehicle control system. The human driver controls a real vehicle in a virtual traffic scenario on a real-world or simulated track.

Use Cases

ADAS and active safety systems (emergency braking, cruise control etc.)

Benefits

VTD operates with real-time performance and high-quality graphics. The vehicle dynamics is “perfect”.
