ADAPTIVE CRUISE CONTROL BRAKING WITH DECELERATION MONITORING
First Claim
1. A vehicle speed control device, including:
- an electronic control unit (ECU);
a forward vehicle sensor, electrically communicating with the ECU, which generates a forward vehicle signal as a function of whether a forward vehicle is detected, the forward vehicle signal indicating a speed and a distance to the forward vehicle;
a speed sensor, electrically communicating with the ECU, which senses a driven vehicle speed; and
control logic, electrically communicating with the ECU and the forward vehicle sensor, controlling the driven vehicle speed as a function of a driven vehicle acceleration and the forward vehicle signal, the control logic setting a fault status as a function of the driven vehicle acceleration and the forward vehicle signal.

Abstract
In one embodiment, a vehicle speed control device includes an electronic control unit (ECU). A forward vehicle sensor, electrically communicating with the ECU, generates a forward vehicle signal as a function of whether a forward vehicle is detected. The forward vehicle signal indicates a speed and a distance to the forward vehicle. A speed sensor, electrically communicating with the ECU, senses a driven vehicle speed. Control logic, electrically communicating with the ECU and the forward vehicle sensor, controls the driven vehicle speed as a function of a driven vehicle acceleration and the forward vehicle signal. The control logic sets a fault status as a function of the driven vehicle acceleration and the forward vehicle signal.
