Abstract: Braking expectation control, based upon manual selection by the driver of the vehicle plus automatic activation (including override of the manual selection) operates to give the following motorist information concerning the type-of-stop. Blinking yellow lights warn of an easy slowdown such as occurs when coasting with the accelerator free. Red stop warning lights burn brightly for a standard stop, as is the case for currently manufactured vehicles. For the panicstop, however, all rear lights come on--red brakelights, red or yellow turn signals together as hazard warnings, hazard lights if separate from the turn signal lights, backup lights--followed by blinking yellow for a continuing warning. The automatic control takes sensor inputs for accelerator-free, foot-on-brake, brake pressure at two levels, stop and panicstop, and includes a timer to determine whether the brake activity is a tap or a more serious stop or panicstop.
