Abstract: An adaptive cruise control system includes a forward-looking sensor generating a range signal corresponding to a distance between the host vehicle and a target vehicle. The forward-looking sensor also generates a range rate signal corresponding to a rate that the distance between the host vehicle and the target vehicle is changing. A controller is electrically coupled to the forward-looking sensor. The controller maintains a preset headway distance between the host vehicle and the target vehicle by adjusting the host vehicle velocity in response to the range signal and the range rate signal. The host vehicle may come to a full stop when the target vehicle is acquired below a predetermined velocity. If the target vehicle is acquired above the predetermined velocity, then a warning is given when braking is required.

Abstract: A brake system includes a brake pedal connected to a brake pedal actuator for applying a variable brake feel force to the brake pedal. A forward detection apparatus is used to detect the relative distance and speed to a target vehicle. A controller monitors the relative distance and speed to notify the driver to slow down. Upon application of the brake, the brake feel force is reduced in proportion to the level of threat detected. In this way, the driver is induced to apply an increased brake pedal force.

Abstract: A multiple channel braking notification system includes an accelerator pedal and an accelerator pedal actuator for applying a variable force to the accelerator pedal. A forward detection apparatus is used to detect the relative distance and speed to a target vehicle. A controller monitors the relative distance and speed to notify the driver to slow down. Driver notification is accomplished by applying a predetermined amount of variable force to the accelerator pedal. The amount of force applied is proportional to the level of braking required.
