Brake Pedal Switch

A Brake Pedal Switch can be used with your ECU for additional Drive-By-Wire safety, datalogging, Cruise Control, Starter Motor Lockout and many other uses and conditions. Up to 2 brake pedal switches can be enabled and configured.

The main node can be used to enable and configure the Brake Pedal Switch inputs types and wiring.

Options

Brake Pedal Switch 1 Input Mode

Select 'Digital - Switched' if the sensor is wired directly to the ECU. Select 'CAN Input' if the selected Vehicle CAN broadcasts the Brake Pedal Switch state to the ECU.

Brake Pedal Switch 2 Input Mode

Select 'Digital - Switched' if a secondary sensor is wired directly to the ECU. Select 'Disabled' if there is no secondary Brake Pedal Switch.

Connections

This area configures the physical input assigned to the Brake Pedal Switch input. Both Analog Inputs and Digital Inputs can be used for the Brake Pedal Switch. Since the switch is an on/off sensor, voltage thresholds must be configured if using an Analog Input, or the Edge Select set if using a Digital (SPI) input.

Generally, the Brake Pedal Switch is wired between the ECU input and ground, and therefore can be set up as follows:

If wired to an Analog Input, set the On Voltage to 2.0v, the Off Voltage to 3.0v, and enable the Pull Up setting. This will hold the input at 5v until such time that the Brake Pedal Switch closes, pulling the input to ground. If your switch is a Normally Closed sensor, swap the On and Off voltages.

If wired to a Digital (SPI) input, set the Edge Select to Falling, Sensor Type to Hall Effect and Pull Up to Enabled. This will hold the input at 12v until such time that the Brake Pedal Switch closes, pulling the input to ground. If your switch is a Normally Closed sensor, swap the Edge Select value to Rising.
