How to Stimulate the ECUs Sensors
Modern electronic control units (ECUs) contain a wide variety of sensors that are often deeply integrated into the ECU and cannot be separated. To test these sensors, the ECUs need to be presented with real stimuli to capture their response.
dSPACE test benches provide the ability to apply the right stimuli for these applications, e.g., by using motion platforms. Special solutions are developed in consultation with the customer.
Examples of use cases include the following:
- Brake control unit, e.g., ESP, parking brake
- ABS/wheel speed sensors
- Passenger detection
- Steering angle sensor
- Acceleration, speed, and angle sensor
- Gyroscope
- Consumer goods, e.g., bicycle airbag sensors
Generation of Realistic Sensor Input
Additional sensor input for real-time simulation is provided by simulation models such as dSPACE Automotive Simulation Models (ASM). They enable the creation of all the input you need to test the ECU thoroughly. dSPACE ASM includes specialized models for different use cases, for example, ASM Vehicle Dynamics.
Different Methods of Sensor Stimulation
Depending on the application, mechatronic test benches from dSPACE offer various options for sensor stimulation. Typical applications include the stimulation of the following:
- Inductive engine speed sensors using controlled coils
- Pressure membranes via strong lifting magnets or linear actuators
- Temperature sensors via controlled hot plates or Peltier elements
- Integrated switches via magnetic fields
- Integrated acceleration sensors and yaw rate sensors via a 3D motion platform or tilt rockers
- Integrated torque sensors via mechanical setups and load motors
