1. A method of controlling a vehicle comprising:
- providing a driver subsystem and an active assist subsystem;
receiving at least one driver input into the driver subsystem from a driver of the vehicle;
outputting a driver output from the driver subsystem to the active assist subsystem, the driver output being derived from the at least one driver input;
providing at least one active assist program having at least one active input, the at least one active assist program having an on setting wherein the at least one active assist program outputs at least one active input and an off setting wherein the at least one active assist program does not output at least one active input;
providing a vehicle control and implementation subsystem; and
inputting an intended driving demand from the active assist program into the vehicle control and implementation subsystem;
wherein the intended driving demand is derived from a combination of the at least one driver input and the at least one active input if the at least one active assist program is in the on setting and if the driver of the vehicle does not overrule the at least one active assist program, otherwise the intended driving demand is derived from the at least one driver input, such that the vehicle control and implementation subsystem cannot determine if its instructions come from the at least one driver input or the at least one active assist program.

Abstract
A vehicle control system (10) including a vehicle motion control subsystem (12) that has an input receiving an intended driving demand (14) and a plurality of coordinator subsystems (16) for coordinating actuators of the vehicle. The vehicle motion control subsystem (12) communicates with the coordinator subsystems (16) to determine whether a single coordinator subsystem (16) can carry out the intended driving demand (14). The vehicle motion control subsystem (12) will distribute demand signals among one or more of the coordinator subsystems (16) to allow the vehicle to implement the intended driving demand (14).

11. A vehicle control system comprising:
-
a driver subsystem receiving at least one driver input from a driver of the vehicle, the driver subsystem including a driver output outputting a driver output signal, the driver output signal being derived from the at least one driver input;
an active assist subsystem including an assist input receiving the driver output signal from the driver output of the driver subsystem, the active assist subsystem including at least one active assist program having at least one active input, the at least one active assist program having an on setting wherein the at least one active assist program outputs at least one active input and an off setting wherein the at least one active assist program does not output at least one active input, the at least one active assist subsystem including an assist output;
a vehicle control and implementation subsystem having a control input receiving an intended driving demand from the assist output of the active assist program;
wherein the intended driving demand is derived from a combination of the at least one driver input and the at least one active input if the at least one active assist program is in the on setting and if the driver of the vehicle does not overrule the at least one active assist program, otherwise the intended driving demand is derived from the at least one driver input, such that the vehicle control and implementation subsystem cannot determine if its instructions come from the at least one driver input or the at least one active assist program. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
