Abstract
A method is described comprising modulating vehicle speed about a target speed by operating a vehicle with an engine at high output and then operating the vehicle with the engine off, and adjusting operation of a suspension system based on the vehicle operation with the engine at high output and the engine off to control vehicle pitch during the modulating of vehicle speed about the target speed.
Claims20
A method, comprising:
- modulating a vehicle speed about a target speed during cruise control operation by repeatedly operating one or more engine cylinders to increase the vehicle speed, and then deactivating one or more engine cylinders to reduce the vehicle speed, via a control system;
- and
- adjusting a vehicle suspension system based on the cylinder operation to control vehicle pitch during the vehicle speed modulation.
A vehicle, comprising:
- an engine;
- a suspension system;
- and
- a control system including one or more controllers, a network, and one or more memories with instructions executable stored therein to modulate a vehicle speed about a target speed by operating the vehicle with the engine at increased output and then with the engine off, and adjust suspension system operation based on the vehicle operation to control vehicle pitch during the modulating of the vehicle speed about the target speed.

A method for a control system of a vehicle, comprising:
- via the control system:
- during vehicle-controlled speed regulation, operating one or more engine cylinders to increase the vehicle speed, and then deactivating one or more engine cylinders to reduce the vehicle speed without a change in driver pedal request;
- and
- adjusting a vehicle suspension system responsive to the vehicle-controlled speed regulation and in coordination with timing of the increase and decrease in vehicle speed.
