Test Kit for Thermal Management Modules

Thermal Management Modules (TMM) distribute the cooling water in the combustion engine. These replaced the so-called thermostat, which previously regulated the cooling circuits in the engine. In contrast to the thermostat, TM modules have active components such as electric actuators and sensors for the optimal distribution of the cooling water.

For development and testing, IgH has developed a test kit that allows TM modules to be operated outside the vehicle and independently of the control unit.

Key features of the test kit are:

• a variable voltage supply for actuators: 9-16V
• various interfaces for reading out sensors
• PWM, LIN, SENT and CANbus-Interface
• servocontroller for position control
• measurement of current consumption and supply voltage of actuators
• condition monitoring of the connected sensors
• touch screen with modern operator panel
• potentiometer for setpoint setting
• emergency stop to interrupt the power supply to the actuators

The TMM test kit also has USB and network interfaces. These are used to update the firmware and transfer parameter sets. Linux is used as operating system for the built-in PC.

Measurement data can be put out in real-time via Ethernet or CANbus. Furthermore, the test case can be completely remote controlled via CANbus.

Analogue outputs can be used to control external components. These outputs are galvanically isolated.

Due to the mechanically robust design, the TMM test kit can also be used in demanding environments. The protection category is IP54 with closed cover and IP20 with open cover.
