Pedal Haptics

Screenshot

Overview

We now have support for Simagic’s HPR (Haptic Pedal Reactors). These are mounted onto your Simagic P1000 or P2000 pedals, or custom mounted to pedals for other manufacturers, and connected to a Simagic P2000 controller box.

The Simagic P-HPR Neo Rumbles are supported as well.

Enable and Disable

The pedal haptics tab has a checkbox in the tab header to turn on and off this feature.

Pedal Effects

There are several effects currently supported by this feature. Each pedal can support up to three pedal effects, and each effect has its own vibration intensity slider. The order of the effects for each pedal is important – only one effect can be felt at a time – so put the most important and shorter effects at the top. For example, in the screenshot above, the brake pedal has the following effects in this order –

  1. ABS Engaged
  2. Wheel Lock
  3. Steering Effects

What this means is that you feel the steering effects only when the ABS is not engaged and the wheels are not locking up.

Gear Change

The gear change effect is driven directly by iRacing telemetry data. There is a heavy thump when shifting out of neutral and into any other gear, and a lighter thump when shifting into neutral.

ABS Engaged

The ABS engaged effect is driven directly by iRacing telemetry data. The pedal will start pulsing when iRacing says that the ABS system is active, and the strength of the pulses depends on how hard you are pressing on the brake pedal.

RPM (Wide)

The RPM (Wide) effect is driven directly by iRacing telemetry data. Starting at half shift RPM, the pedal will start to vibrate softly at a low frequency, and the vibration will ramp up in both frequency and strength until the engine reaches the recommended shift RPM.

RPM (Narrow)

The RPM (Narrow) effect is driven directly by iRacing telemetry data. Starting when the engine is within 5% of the recommended shift RPM, the pedal will start to vibrate softly at a low frequency, and the vibration will ramp up very quickly in both frequency and strength until the engine reaches the recommended shift RPM.

With this effect, the pedal does not vibrate when you are already in top gear.

Steering Effects

The vibrations for the steering effects are driven by the settings you have chosen on the Steering Effects tab. Both the understeer and the oversteer effects can be felt. Make sure to visit the steering effects tab and set the Fx Style to Pedal Haptics for the steering effects you want to feel in the pedals.

Wheel Lock

The wheel lock effect is a calculated effect. The wheel lock is estimated based on the running average of the ratio of engine RPM to forward speed, for each gear. When MAIRA detects that the current ratio is 5% higher than the running average, it assumes that the wheels are locking up, and vibrates the pedals. This effect is automatically disabled when the clutch is pressed in. This effect does not work correctly to detect wheel lock on the front wheels of a rear wheel drive car.

Wheel Spin

The wheel spin effect is a calculated effect. The wheel spin is estimated based on the running average of the ratio of engine RPM to forward speed, for each gear. When MAIRA detects that the current ratio is 5% lower than the running average, it assumes that the wheels are spinning, and vibrates the pedals. This effect is automatically disabled when the clutch is not fully engaged.

Clutch Slip

When the clutch is between 25% and 75% engaged, the pedal vibrates. The frequency of the vibration is based on the engine RPM.

Pretty Graphs

You can enable the pretty graphs for the pedal haptics by clicking on the Enable Pretty Graphs button. This will show three graphs, one for each pedal, and you will be able to visually see the vibrations for each pedal.
