Vehicle controller with complementary capacitance for analog-to-digital converter (A/D) low pass filter

A method of processing control signals of different frequency ranges, the method comprising:

• providing a control circuit configured to receive an input signal and to control at least one engine output based on the input signal;
• configuring a first setting of an adjustable low-pass filter to cause the adjustable low-pass filter to have a first cut-off frequency or configuring a second setting of the adjustable low-pass filter to cause the adjustable low-pass filter to have a second cut-off frequency, wherein the first setting configures the control circuit to be used with a first sensor having a first dynamic range and the second setting configures the control circuit to be used with a second sensor having a second dynamic range;
• and
• causing the adjustable low-pass filter to filter the input signal prior to forwarding the input signal to the control circuit.

A computer-readable medium containing computer-executable instructions stored thereon, the instructions, when executed by at least one processor, cause the at least one processor to:

• configure a first setting of an adjustable low-pass filter to cause the adjustable low-pass filter to have a first cut-off frequency or configuring a second setting of the adjustable low-pass filter to cause the adjustable low-pass filter to have a second cut-off frequency, wherein the first setting configures a control circuit to be used with a first sensor having a first dynamic range and the second setting configures the control circuit to be used with a second sensor having a second dynamic range;
• receive a filtered input signal from the adjustable low-pass filter;
• and
• control a vehicle component or system output based on the filtered input signal.
