Abstract
A vehicle control system includes a processor programmed to control a vehicle subsystem according to a recovered signal generated from an output signal of a sensor, and a product of a time constant of the sensor and filtered changes of the output signal with respect to time such that a magnitude and phase of the recovered signal approach a magnitude and phase of an input signal to the sensor.
Claims20
A vehicle control system comprising:
- a processor programmed to control a vehicle subsystem according to a recovered signal generated from a sum of an actual output signal of a sensor and a product of a time constant of the sensor and filtered changes of the output signal with respect to time such that a magnitude and phase of the recovered signal approach a magnitude and phase of an actual input signal to the sensor.
A vehicle system controller comprising:
- input channels configured to receive an actual output signal of a sensor;
- output channels configured to control a vehicle subsystem according to a recovered signal;
- and
- control logic configured to generate the recovered signal from a sum of the output signal and a product of a time constant of the sensor and filtered changes of the output signal with respect to time such that a magnitude and phase of the recovered signal approach a magnitude and phase of an actual input signal to the sensor.
