Abstract

A cruise control method includes determining that a host vehicle is traveling downhill and determining an axle torque command to maintain a predetermined headway distance from the host vehicle to a lead vehicle while the host vehicle is traveling downhill. The method further includes determining that a brake of the host vehicle is actuated to provide the axle torque command previously determined and comparing the axle torque command with a brake exit threshold to determine whether the axle torque command is greater than the brake exit threshold. Further, the method includes comparing the headway distance between the host vehicle and the lead vehicle with a headway exit threshold to determine whether the headway distance between the host vehicle and the lead vehicle is greater than the headway exit threshold. Also, the method includes commanding the brake of the host vehicle to disengage to terminate braking.
