System and method for validating adaptive cruise control operations
A method of operating a vehicle comprising an adaptive cruise control system and an engine control module is provided. The engine control module is coupled to the adaptive cruise control system. The method comprises issuing a speed reduction signal from the adaptive cruise control system, verifying a speed reduction with a first sensor using the adaptive cruise control system, verifying the speed reduction with a second sensor using the engine control module, thereafter, receiving a resume signal from an operator input device, and executing a speed increase of the vehicle with the engine control module in response to receiving the resume signal with the engine control module.
1. A vehicular control system for a vehicle, the system comprising:
an adaptive cruise control system configured to:
engage an adaptive cruise control mode in response to receiving an engagement signal from an operator of the vehicle;
transmit a speed reduction signal during the adaptive cruise control mode;
verify speed reduction of the vehicle using a first sensor, the speed reduction of the vehicle being influenced by the speed reduction signal;
receive a resume signal from the operator during the adaptive cruise control mode; and
transmit a speed increase signal in response to receiving the resume signal; and
an engine control module coupled to the adaptive cruise control system and configured to:
receive the speed reduction signal;
execute the speed reduction in response to receiving the speed reduction signal;
verify the speed reduction using a second sensor;
receive the resume signal; and
execute a speed increase of the engine in response to receiving the resume signal and the speed increase signal.
2. The vehicular engine control system of claim 1 , wherein the first sensor comprises a wheel speed sensor.
3. The vehicular engine control system of claim 1 , further comprising a range-finding system configured to determine a following distance between the vehicle and a preceding vehicle and to transmit an alert signal in response to detecting a following distance below a proximity threshold.
4. The vehicular engine control system of claim 3 , wherein the adaptive cruise control system is further configured to transmit the speed reduction signal in response to receiving the alert signal.
5. The vehicular engine control system of claim 1 , further comprising a resume button adapted to transmit the resume signal in response to manipulation by the operator.
