Abstract
An enhanced autonomous emergency braking system includes an accelerator pedal operated by the driver and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle while the vehicle engine speed is reduced. The amount of brake force applied is a continuous function of relative speed, relative distance, collision probability and target classification. The braking force may be reduced when the driver or passenger are unbuckled or may be disabled if the driver depresses the accelerator pedal by a predetermined amount. In addition, the amount of brake force applied by the driver is amplified to further enhance braking performance.
