1. A pressure module for use with a hydraulic brake system of a driving simulator, the pressure module comprising:
a connector configured to provide a fluid connection between the pressure module and a hydraulic system of the driving simulator, the hydraulic system comprising a master side and a slave side, the fluid connection including a master side fluid connection for hydraulic fluid communication with a master cylinder of the hydraulic brake system and a slave side fluid connection for hydraulic fluid communication with a slave cylinder of the hydraulic brake system;
an accumulator for increasing the volume and thereby decreasing the pressure of the hydraulic system;
a pump for increasing the pressure of the hydraulic system;
a first valve arranged to control the fluid communication between the accumulator and the master side fluid connection such that when the first valve is open, the master side fluid connection is in fluid communication with the accumulator chamber volume and the master side fluid connection experiences a decrease in hydraulic fluid pressure due to the accumulator chamber volume;
a second valve arranged to control the fluid communication between the master side and the slave side of the hydraulic system,
wherein the pump, the first valve and the second valve provide a tactile feedback by intermittently increasing and decreasing the pressure of the hydraulic system.
